What is a polystyrene floor skirting board

Polystyrene skirting board is made from expanded polystyrene — a synthetic polymer with unique properties. The material consists of 98% air enclosed in billions of microscopic cells, which explains its incredible lightness while maintaining sufficient strength for household use.

The production technology is based on extrusion or injection molding. Polystyrene granules are heated, foamed, and formed into profiles of the desired configuration. Modern equipment allows creating products with clear lines, diverse relief patterns, and flawless geometry. From simple rectangular strips to elegant profiles with decorative grooves — the assortment satisfies any request.

Technical Parameters

Floorpolystyrene skirting board for floorIt has the following characteristics:

Profile height: varies from 40 to 150 millimeters. The most popular models are 60-80 mm for standard apartments and 100-120 mm for rooms with high ceilings.

Thickness: Standard thickness is 10-20 mm, providing a balance between strength and lightness. The popular request "buy polystyrene skirting board 80mm 12mm" reflects optimal parameters for most residential spaces — height 80 mm and thickness 12 mm.

Plank length: Industry standard — 2 meters. This length is convenient for transportation, storage, and installation. Some manufacturers offer 3-meter variants to reduce the number of joints in long rooms.

Weight: One linear meter weighs only 120-200 grams depending on profile height. For comparison — a wooden analog weighs 500-800 grams.

Material density: 25-35 kg/m³, which is 15-20 times lighter than wood and 40 times lighter than plaster.

Physical properties

Water absorption: less than 2% by volume within 24 hours, making the material ideal for humid environments.

Temperature range: from -40 to +70 degrees Celsius. Within these limits, the material retains all its properties.

Thermal conductivity: 0.037-0.040 W/(m·K) — low value, preventing cold bridges.

Bending strength: sufficient for household use, although the material is less resistant to strong mechanical impacts compared to wood and polyurethane.

Service life: under proper use, reaches 30-50 years. The material does not rot, does not suffer from mold, and is not attractive to insects.

Advantages of floor polystyrene skirting boards

The popularity of this material is explained by an impressive list of advantages, making it the optimal choice for various situations.

Affordable cost

This is the first thing that attracts buyers. The cost of polystyrene skirting boards is 3-8 times lower than high-quality wooden analogs. Even with the purchase of glue, sealant, and paint, overall expenses remain minimal. For repairing a 20-square-meter room, materials will cost approximately 1500-2500 rubles.

Minimal weight

The lightness of the material solves many practical problems. Transportation does not require heavy vehicles — material for an entire apartment fits in the trunk of a passenger car. One person can easily bring all the planks to any floor. During installation, no help is needed — all operations are performed alone without physical strain.

Important: a lightweight skirting board does not create additional load on walls, which is critical for structures made of gypsum board, aerated blocks, or other lightweight materials. Water-based glue securely holds the item without additional fasteners.

Absolute water resistance

Unlike wood, MDF, and plaster, polystyrene does not fear water. It can be safely used in bathrooms, showers, kitchens, laundries, pools — anywhere with high humidity. The material does not swell, warp, or lose its shape even with prolonged contact with water.

In case of flooding from upstairs neighbors, it is enough to dry the skirting boards — they will restore their original appearance. Wooden analogs in such a situation are irreversibly damaged.

Ease of processing and installation

Questions "what to cut polystyrene skirting board with" and "what to saw polystyrene skirting board with" concern many beginners. The answer is simple: any sharp tool. Construction knife, fine-toothed hacksaw, circular saw, jigsaw — all are suitable. No special machines or expensive equipment are required.

installation of polystyrene baseboardsSo simple that even a person without construction experience can handle it. No self-tapping screws, anchors, or drill required — only glue and a minimal set of tools.

Design versatility

The white color of the products — a clean canvas for creativity. Skirting boards can be easily painted with any water-based paint, allowing them to be adapted to any interior. From classic white to bright accent colors, from matte to glossy surfaces — possibilities are limitless.

Variety of profiles will satisfy any taste. Simple smooth planks for minimalism, profiled ones for classic style, tall skirting boards for spacious rooms — the choice is vast.

Ecological safety

At room temperature, polystyrene is inert and does not emit harmful substances. The material is hypoallergenic, contains no formaldehyde, heavy metals, or volatile organic compounds. It can be used in children's rooms, bedrooms, medical facilities.

Quality products have sanitary-epidemiological conclusions and certificates of conformity, confirming their safety for health.

Biological resistance

Polystyrene is a synthetic material that is not attractive to microorganisms, fungi, or insects. Unlike wooden skirting boards, which may be attacked by termites or mold, polystyrene products retain their original appearance for decades.

Even under increased humidity, if mold appears on the walls, the skirting boards themselves will not be affected. It is sufficient to treat the surface with an antiseptic.

Thermal insulation properties

Although the skirting board is not a thermal insulation element in the strict sense, its low thermal conductivity prevents the formation of 'cold bridges' at the junction of the wall and floor. This is especially relevant for ground-floor apartments and corner units.

Disadvantages and limitations

Objectivity requires mentioning the material's weaknesses. Understanding limitations will help avoid disappointments and ensure proper application of the products.

Mechanical strength

Polystyrene is a relatively soft material. Strong impacts from furniture, pressure from sharp objects, or vacuum cleaner impacts will leave dents or punctures. In homes with active children or large pets, the surface may sustain damage.

However, local defects are easily repaired with putty and repainting. In case of serious damage, the damaged section is simply replaced with a new piece.

Sensitivity to solvents

Contact with organic solvents leads to deformation or partial dissolution of the material. This restricts the choice of adhesives, paints, and cleaning agents. It is necessary to carefully read the compositions and avoid products containing acetone, toluene, or white spirit.

Temperature limitations

Although polystyrene withstands temperatures up to 70 degrees, prolonged exposure to heat from radiators or heated floors with high temperatures may cause deformation. It is necessary to maintain a safe distance from powerful heat sources.

Flammability

Polystyrene belongs to combustible materials of class G3-G4. It ignites at around 240 degrees, releasing toxic products. Modern manufacturers add flame retardants, but the material does not become completely non-combustible.

In household conditions, this is not a problem — skirting boards do not come into contact with open flames. However, in case of fire, they will contribute to the spread of flames.

Static electricity

The surface is prone to accumulating static electricity, attracting dust. Skirting boards require more frequent cleaning compared to wooden ones. The problem is resolved by using anti-static agents.

Varieties of floor polystyrene skirting boards

The assortment of floor polystyrene skirting boards is diverse. Let's consider the main categories.

By profile height

Low (40-60 mm). Suitable for small rooms with low ceilings (up to 2.4 m), where a high skirting board visually reduces room height. Also used in modern minimalist interiors, where understated detailing is important.

Standard (60-80 mm). A universal option for most residential rooms with ceilings 2.5-2.7 meters high. Balanced height provides good wall protection and a harmonious appearance. The query 'buy polystyrene skirting board 80mm 12mm' reflects the popularity of this size.

High (90-120 mm). For spacious rooms with ceilings of 3 meters or more. Creates a sense of monumentality and classic elegance. Visually increases the perceived height of the room.

Very high (150+ mm). Primarily for commercial spaces, offices, and reception halls. In a regular apartment, they may appear excessive.

By Profile Type

Simple smooth. Rectangular or slightly rounded profiles without decorative elements. Ideal for minimalism, high-tech, and Scandinavian styles. Simplicity is the main advantage.

With decorative relief. Profiles with grooves, protrusions, and classical molding imitation. Suitable for traditional interiors, neoclassicism, and Provence. Decorative complexity ranges from simple lines to intricate ornaments.

With cable channel. A practical solution for modern apartments with abundant technology. The back of the skirting board has a special recess or removable strip for wire placement. Particularly relevant for offices with many computers and office equipment.

Flexible. Special high-elasticity skirting boards for decorating curved sections — columns, bay windows, rounded walls. More expensive than standard ones, but indispensable in non-standard situations.

By finish variant

White uncolored. Standard variant, ready for installation. Universal white color matches any interior.

With pre-primed finish. Items coated with a thin primer layer, ready for painting. Primer improves paint adhesion and reduces paint consumption.

Colored. Some manufacturers offer skirting boards pre-colored in popular shades. This is convenient, but the choice of shades is limited.

With a wood-grain texture. Wood-like surface pattern on polystyrene. From afar, they look like wood, but retain all the advantages of polystyrene.

Choosing the right skirting board

Correct selection is the key to a successful result. Let's consider the selection criteria.

Matching ceiling height

This is a basic rule: the higher the ceilings, the higher the skirting board can be.

For ceilings up to 2.4 meters, skirting boards 40-60 mm are optimal. They do not visually reduce the room's height.

For standard ceilings of 2.5-2.7 meters, profiles 60-80 mm are suitable. This is the golden middle ground, working in most apartments.

For high ceilings of 3 meters and above, skirting boards 100-120 mm are appropriate, emphasizing the scale of the space.

Style compatibility with interior design

Minimalism, high-tech, modern style: simple smooth profiles without decoration, clean lines, white or gray color.

Classic, neoclassical: profiles with relief imitating traditional moldings, painted in cream, white, or wall tone.

Loft, industrial style: neutral profiles, painted in gray, graphite, or black.

Scandinavian style: simple medium-height white skirting boards, creating contrast with wooden flooring.

Provence, country style: skirting boards with soft relief, painted in pastel shades - beige, lavender, mint.

Matching floor covering

Laminate and parquet flooring: skirting board can be left white for contrast or painted to match wood tone. Modern trend - white skirting boards with dark flooring.

Ceramic tile: choose color to match grout or create contrast with tile color.

Carpet: color can match floor covering for monochromatic effect or contrast.

Linoleum: neutral white, matching floor covering, or contrasting - depends on overall concept.

Resin floor: simple smooth profiles, painted gray to match concrete or white for contrast.

Product quality

When purchasing, carefully inspect the material:

Geometry. Planks must be perfectly straight. Place against a flat surface - there should be no gaps. Curved planks will create gaps during installation.

Surface. Smooth, uniform, without bubbles, dents, or unevenness. Roughness indicates low-quality raw material.

Edges. Sharp, without chips or burrs. Uneven edges will make creating neat joints difficult.

Color. Uniform white along the entire length. Yellowing, gray spots, or color variations indicate low-quality raw material or manufacturing defects.

Odor. A mild, specific odor is acceptable and quickly dissipates. A sharp chemical odor indicates low-quality material.

Manufacturer and price

Do not compromise on quality. The price difference between good and poor materials is small - 20-30%, but the result is drastically different. Quality skirting boards have precise geometry, strong structure, and uniform color.

Require compliance certificates. A reputable seller will provide them immediately.

Material quantity calculation

Measure the room's perimeter with a tape measure. Subtract the width of doorways (usually 80-90 cm each). Add 10-15% for trimming and potential defects.

Example: room 4x5 meters. Perimeter 18 meters. One door opening 0.9 meters. Total: 18 - 0.9 = 17.1 meters. With 15% reserve: 17.1 x 1.15 = 19.7 meters. Standard plank length 2 meters: 19.7 / 2 = 9.85. Round up to 10 planks.

For rooms with complex geometry, bay windows, niches, make a detailed drawing and calculate the material based on it.

Detailed installation instructions

installation of polystyrene baseboardsA process accessible to everyone. Follow the instructions, and the result will be professional.

Preparation of the room and tools

Wall inspection. Walls must be flat, clean, and dry. Significant unevenness (more than 5 mm) will hinder tight fitting. Level with putty if necessary.

Cleaning. Remove dust with a vacuum cleaner, then wipe with a damp cloth. Pay special attention to the lower part of the walls where the skirting board will be glued. Wipe grease stains with alcohol. Allow the surface to dry completely.

Acclimatization. Bring the material into the room 24 hours before installation. Temperature adaptation prevents deformation after installation.

Tools:

• Miter gauge for precise corner cutting

• Fine-tooth hacksaw

• Sharp utility knife

• Tape measure and pencil

• Adhesive for polystyrene skirting boards

• Narrow putty knife

• Sandpaper (grit 120-180)

• White acrylic sealant

• Sealant caulking gun

• Clean rag

• Painter's tape

Choosing and preparing adhesive

Use only specialized compositions for polystyrene. Suitable:

Polymer construction adhesives on acrylic or rubber base. They set quickly, create a strong bond, and do not damage the material.

Liquid nails marked "for polystyrene" or "universal solvent-free". Check the composition — should not contain organic solvents.

Acrylic spackling compounds. Finishing acrylic spackling compound can be used as adhesive. Advantage — simultaneously bonds and fills wall imperfections.

Strictly prohibited: adhesives based on organic solvents, silicone sealants, cyanoacrylate super glues.

Cutting technique

Questions "what to cut polystyrene skirting board with" and "what to saw polystyrene skirting board with" are resolved by choosing the right tool.

Straight cut. For cutting in the middle of the plank, use a fine-tooth hacksaw or a sharp utility knife. Mark the cut location with a pencil. Cut slowly without heavy pressure to avoid chipping.

45-degree angle cut. Use a miter gauge — a device with slots for required angles. Insert the skirting board into the miter gauge, align it with the required slot, press firmly, and cut with confident movements.

Rule for internal corners: the left plank is cut so that the long side of the cut is against the wall (bottom), the short side — toward the room (top). The right plank is mirrored.

Rule for external corners: the long side of the cut should be toward the room (top), the short side — against the wall (bottom).

Cleaning. After cutting, inspect the end. Lightly sand the burrs with sandpaper. A perfectly smooth cut ensures a tight joint without gaps.

Adhesive application process

Marking. Start from the corner most visible upon entering the room. If all corners are equally visible, start from the farthest one.

Apply adhesive in a thin line or in dots spaced 10-15 cm apart on the back of the skirting board. Leave 3-5 mm from the edges to prevent excess adhesive from squeezing out.

For uneven walls, use more adhesive or spackle. Apply in a thick layer — the material will fill irregularities and simultaneously bond the skirting board.

Installation. Press the board against the wall, aligning it with the bottom edge (the skirting board must fit tightly against the floor). Press firmly along the entire length. Hold for 30-60 seconds to allow initial adhesive setting.

Joining boards. Install the next board butt-joint to the previous one. Apply a thin layer of adhesive to the end of the first board to seal the joint. Place the second board, align it vertically, and press firmly.

The joint should be almost invisible. If there is a small gap, it’s not a problem — fill it later with sealant.

Removing excess. Immediately wipe away squeezed-out adhesive with a damp cloth. Removing dried adhesive is significantly more difficult.

Working with corners

Corners — the most critical stage. A correctly executed corner joint is practically invisible.

Internal corners. Prepare two boards with 45-degree bevels. Place them at the corner without adhesive — check the fit. If there is a gap, lightly sand the ends with sandpaper.

Apply adhesive to both boards. First, attach one board, pressing firmly into the corner. Allow 2-3 minutes to set. Then attach the second board, pressing firmly against the first at the joint.

External corners. The technique is the same, but the bevels are mirrored. External corners are more noticeable, so pay special attention to cutting accuracy.

Uneven corners. If walls meet at an angle other than 90 degrees, a standard 45-degree cut won’t work. Measure the actual angle, divide it in half, and cut at that angle. Or use the trial method: make several test cuts on scrap pieces, gradually achieving perfect fit.

Filling joints and gaps

After the adhesive dries (12-24 hours), inspect the work. Fill gaps between boards and minor gaps between skirting board and walls/floor with acrylic sealant.

Fill the caulking gun with sealant. Trim the nozzle tip at an angle — the opening should be narrow (2-3 mm). Carefully apply sealant in a thin line directly into the gap.

Smooth the sealant with your finger or a rubber spatula dipped in soapy water. The motion should be confident, in one smooth stroke. This will create a perfectly smooth surface without waves.

Immediately wipe away excess with a damp cloth. Allow to dry for 2-4 hours. After complete drying, the sealant can be painted along with the skirting board.

Typical installation mistakes

Installing on a dirty wall. Dust and dirt reduce adhesion. Result — the skirting board will peel off within several months.

Using unsuitable adhesive. Adhesives with solvents damage polystyrene. Check the composition before purchasing.

Rushing corner cuts. Inaccurate cuts create gaps at joints. It’s better to spend time on precise fitting than to patch gaps with sealant.

Insufficient adhesive. Saving on adhesive leads to peeling. Apply enough adhesive for secure fixation.

Ignoring wall irregularities. On uneven walls, gaps form between the skirting board and the surface. Use more adhesive or pre-level the walls.

Painting polystyrene skirting boards

The question 'what to paint polystyrene skirting board with' arises when white doesn't fit the interior design concept.

Paint Selection

Water-based acrylic paints. Optimal choice. No solvents, dry quickly, no strong odor, available in a wide color range. Choose paints for interior use with matte or satin finish.

Water-dispersed paints. Eco-friendly, affordable, easy to apply. Easily tinted to any shade. Provide even coverage.

Latex paints. Form a durable, washable coating. More expensive than standard, but justified for skirting boards in hallways or kitchens.

Absolutely not to use: oil-based paints, alkyd enamels, nitro paints — all contain solvents that damage polystyrene.

Preparation for painting

Cleaning. The surface must be perfectly clean. Remove dust with a dry cloth. Wipe with a mild soapy solution, then rinse with clean water and dry.

Priming. Apply acrylic primer on water-based with a thin layer using a brush or roller. Primer improves paint adhesion and reduces paint consumption by 20-30%. Drying time - 1-2 hours.

Surface Protection. Apply painter's tape tightly to walls and floor up to the baseboard. Protect flooring with plastic sheeting or old newspapers.

Painting Technology

Tools. Use a 40-60 mm wide brush with soft bristles or a velvet roller. A brush provides better control, while a roller gives a smoother, streak-free finish.

First Layer. Apply paint in a thin, even layer along the baseboard. Do not attempt to cover the entire surface at once — a thick layer will cause runs. The first layer may not be perfectly even — this is normal. Allow 2-4 hours to dry.

Second Layer. Apply after the first layer is fully dry. Brush strokes should be perpendicular or light crosswise for even coverage.

Third Layer. A third layer may be required for deep, dark colors. Apply only after the second layer is fully dry.

Removing Tape. Remove tape 10-15 minutes after painting, when the paint has set but not yet hardened. Peel slowly at a sharp angle.

Decorative Techniques

Painting to Match Floor. Creates a visual expansion of the floor area. Choose paint as close as possible to the floor covering’s shade.

Painting to Match Walls. The baseboard 'melts' into the wall, creating a seamless transition effect. Visually increases room height.

Contrasting Painting. A dark baseboard on light walls or vice versa creates a clear graphic line, adding expressiveness to the interior.

Two-Tone Solution. Divide the baseboard horizontally — upper and lower sections in different colors. First paint the lower section, then apply tape after drying, then paint the upper section.

Patina Effect. For classic interiors: apply a light base coat, let it dry, then apply a darker paint and partially rub it off with a damp cloth. Seal with matte varnish.

Care and Maintenance

Proper care will extend the lifespan and maintain an impeccable appearance.

Regular cleaning

Weekly Dry Cleaning. Wipe baseboards with a dry, soft cloth or a special cleaning cloth to remove dust. For textured profiles, use a soft brush.

Monthly Wet Cleaning. Wipe with a damp (not wet) cloth. Add a few drops of dish soap or a non-abrasive all-purpose cleaner to the water.

Stain Removal. Wipe fresh stains immediately with a damp cloth. For old stains, soak with warm soapy water, then gently scrub with a soft sponge.

Antistatic Treatment. Every 2-3 months, treat the surface with an antistatic spray for plastic. This reduces dust attraction.

What to Avoid

• Abrasive powders and stiff sponges — scratch the surface

• Solvents (acetone, gasoline, white spirit) — dissolve the material

• Hot water above 60 degrees — may deform

• Strong alkalis and acids — damage the structure

• Stiff brushes — leave scratches

Protection against damage

When moving furniture, use protective pads on legs. Do not drag heavy furniture close to walls.

Distance from heaters — minimum 30 cm. Prolonged exposure to high temperatures deforms the material.

In the bathroom, ensure good ventilation. After bathing, wipe baseboards dry.

When using a vacuum cleaner, be careful — brush impacts leave dents.

Repair of damage

Minor scratches. On painted skirting boards, touch up the damaged area with the same paint using a fine brush. On white items, light scratches can be filled with acrylic putty.

Dents. Fill with acrylic putty, let dry, then sand with fine-grit sandpaper. Paint to match the skirting board color.

Chips. If a piece has broken off, restore the shape with putty. Apply putty generously, let dry, then sand to the desired shape, prime, and paint.

Delamination. If a section has detached from the wall, remove any remaining old adhesive. Apply fresh adhesive, press firmly, and secure with painter’s tape for 24 hours.

Replacing a damaged section. For severe damage, cut out the damaged fragment with a sharp knife. Prepare a new piece of the same length with properly angled edges. Attach it in place of the old one, seal the joints with sealant, and paint if necessary.

Combination with various finishing materials

Harmony between the floor skirting and floor and wall finishes is an important design element.

With floor coverings

Laminate and parquet flooring. The most common combination. A white skirting on a dark floor is a modern trend that visually expands the space. A skirting painted to match the wood tone creates a classic harmonious look.

Ceramic tile. Polystyrene skirting is a practical alternative to ceramic. Easier to install, cheaper, and easily replaceable if damaged. Choose a color to match the grout or create a contrast.

Carpet. The skirting holds the edge of the covering, preventing it from curling. The color can match the carpet for a monochromatic effect or contrast.

Linoleum. Standard combination. The skirting covers the edge of the linoleum and secures it to the wall. Universal white or to match the covering.

Cast-in-place floor. Smooth polystyrene profiles do not overwhelm a minimalist look. A gray skirting to match the concrete or white for contrast — both options work.

With wall coverings

Wallpaper. The skirting is installed after wallpapering, pressing the bottom edge. A white skirting is universal; painted to match the walls creates a unified plane.

Painted walls. Ideal combination. You can paint the skirting to match the walls for a monochromatic look or create a contrast.

Decorative plaster. A smooth skirting creates a pleasant contrast with the textured wall surface.

Wall panels. When using panels, the skirting is installed after panel mounting, covering the bottom edge.

Comparison with alternative materials

For objectivity, compare polystyrene skirtings with similar alternatives.

Characteristic	Polystyrene	Wood	MDF	Polyurethane	Plastic	Ceramic
Price	Low	High	Medium	Medium to high	Low	High
Weight	Very Light	Heavy	Medium	Medium	Light	Very heavy
Moisture resistance	Good	Low	Medium	Good	Good	Good
Strength	Medium	High	Medium	High	Low	Very High
Ease of Installation	Very simple	Complex	Medium	Medium	Simple	Very complex
Paintability	Yes	Yes	Yes	Yes	Limited	No
Durability	30-50 years	More than 50 years	15-25 years	More than 50 years	10-20 years	More than 50 years
Ecological	Good	Good	Medium	Good	Medium	Good

It is evident from the table that polystyrene is optimal in terms of price-quality-ease of installation. It is inferior to wood in prestige, to polyurethane in strength, and to ceramic in durability, but for most household applications these advantages are insignificant compared to the accessibility and practicality of polystyrene.

Special cases of application

Consider non-standard situations for using polystyrene skirting boards.

Warm floor

With an electric or water-based warm floor, polystyrene skirting boards can be used without restrictions. The surface temperature of the floor rarely exceeds 28-30 degrees, which is significantly lower than the critical 70 degrees for polystyrene.

However, avoid installing directly against the pipes of the warm floor where they exit through the wall. Maintain a minimum distance of 5-10 cm from hot elements.

Balconies and loggias

On glazed, heated balconies, polystyrene skirting boards work excellently. They are not recommended for open balconies — ultraviolet radiation and temperature fluctuations accelerate material aging.

On cold balconies, use skirting boards painted with UV-resistant paints.

Commercial Spaces

In offices, stores, cafes, polystyrene skirting boards with cable channels — a practical solution. Quick installation, easy replacement upon damage, low cost make them the optimal choice.

For high-traffic areas, choose thicker and more durable profiles or consider polyurethane alternatives.

Wet rooms

In bathrooms, showers, pools, and laundries, polystyrene performs excellently due to its moisture resistance. The main condition — good ventilation to prevent mold formation at joints.

Treat all joints with antiseptic sealant. When painting, use moisture-resistant paints with antiseptic additives.

Rooms with heightened sanitary requirements

In medical facilities, kindergartens, and food production facilities, polystyrene skirting boards are permissible due to the material's hygiene. The smooth surface is easy to clean, does not accumulate dirt, and is resistant to water-based disinfectants.

Frequently asked questions

Can floor polystyrene skirting boards be used on the ceiling?

Technically yes, but not recommended. Floor skirting boards are designed for vertical installation and have a corresponding profile. For ceilings, it is better to use special ceiling moldings (coving), which have optimal geometry for horizontal mounting.

How long does it take to install skirting boards in a room?

For an inexperienced person, installation in a standard room of 15-20 m² takes 3-4 hours including preparation, cutting, and installation. An experienced professional can complete it in 1-1.5 hours. Most of the time is spent on precise corner fitting.

Do you need to remove skirting boards when replacing floor covering?

Yes, it is recommended. New flooring may have a different thickness, requiring adjustment of the skirting board height. Additionally, when laying laminate or parquet, a compensatory gap is needed, which is covered by the skirting board. Remove skirting boards carefully — with careful dismantling, they can be reinstalled.

Can polystyrene skirting boards be glued to wallpaper?

Yes, but not recommended. The adhesive sticks to the wallpaper, not the wall, reducing the reliability of the mounting. It may be possible with heavy vinyl wallpaper, but for paper wallpaper, the risk of peeling is high. It is better to install skirting boards before wallpapering or leave a gap between the wallpaper and the floor for the skirting board.

How often should painted skirting boards be renewed?

It depends on usage intensity and paint quality. In bedrooms, painted skirting boards retain their appearance for 7-10 years. In hallways or corridors with high traffic — 3-5 years. When scratches, scuffs, or sun fading appear, a light sanding and fresh coat of paint are sufficient.

How to fill a large gap between skirting board and uneven wall?

For gaps up to 5 mm, use acrylic sealant. For larger gaps (5-10 mm), apply acrylic putty — spread with a trowel, smooth, sand after drying, and paint. For very large gaps (over 10 mm), it is better to level the wall with putty before installing the skirting board.

How to connect skirting boards of different heights?

When transitioning between rooms, it may be necessary to connect skirting boards of different heights. Create a smooth transition: cut both boards at an angle, creating a slope from higher to lower. Fill and sand the joint for a smooth transition.

Do polystyrene skirting boards deteriorate from sunlight?

Direct sunlight may cause yellowing of white polystyrene over time. The process is slow — noticeable changes after 5-7 years of constant exposure. Colored skirting boards are more resistant, but the paint may fade. For rooms with intense sunlight, use UV-resistant paints with UV filters.

No, absolutely not. The temperature in saunas and steam rooms exceeds 70-80 degrees, which will cause deformation and even melting of polystyrene. For such rooms, use wooden skirting boards made of thermally treated wood or special heat-resistant materials.

How to remove a glued skirting board if necessary?

Carefully pry the skirting board with a thin putty knife or knife, moving along the board. Work slowly, gradually detaching from the wall. When using quality adhesive, the skirting board will likely be damaged — polystyrene is softer than the adhesive bond. After removal, clean the wall of adhesive residue with a putty knife, and if necessary, soften it with warm water.

Carefully pry up the skirting board with a thin putty knife or knife, moving along the strip. Work slowly, gradually detaching from the wall. With quality adhesive, the skirting board will likely be damaged—the vinyl is softer than the adhesive bond. After removal, clean the wall of adhesive residue with a putty knife, and if necessary, soften it with warm water.

Does polystyrene skirting board affect room sound insulation?

The effect is minimal. The porous structure of the material provides some sound absorption, but due to its small surface area, the effect is insignificant. To improve sound insulation, use specialized wall and floor materials — skirting boards are merely a decorative element.

Can polystyrene skirting board be used with underfloor heating systems?

No, it is absolutely unsuitable. Underfloor heating systems heat the skirting board to 70-90 degrees, which will cause deformation of polystyrene. For such systems, use special metal or heat-resistant plastic profiles.
