Technical Specifications of D40V2 Profile

Model D40V2 is a wall profile of classic shape with a height of 40 mm and an elegant multi-level relief, creating a striking play of light and shadow on the wall surface. The height of 40 mm is optimal for creating a noticeable decorative effect — the profile is sufficiently expressive to structure the space and attract attention, yet does not appear bulky even in medium-sized rooms. The thickness of the profile, 16.5 mm, ensures sufficient structural strength with minimal weight, facilitating installation and not creating load on walls.

Standard length of 2000 mm simplifies calculation of required material quantity for room finishing and minimizes the number of joint seams during perimeter installation. The D40V2 profile has a symmetrical shape with a central protruding element and side grooves, creating a classic architectural pattern. Clear line geometry and smooth transitions between relief levels are achieved thanks to high-precision computer-controlled manufacturing equipment.

The material used is high-density polystyrene (durable polymer, plant polymer) — a modern thermoplastic polymer subjected to special technological processing. The material density is 600-650 kg/m³, significantly exceeding the indicators of ordinary polystyrene foam and providing increased mechanical strength. The extrusion technology under high pressure followed by slow cooling creates a homogeneous structure without voids, cavities, or internal stresses. The weight of one profile is approximately 0.30-0.40 kg, allowing installation on any type of wall without risk of detachment due to its own weight.

Unique properties of the material

Polystyrene impact-resistant wall moldingHi Wood model D40V2 possesses a complex set of unique characteristics making it the optimal choice for decorating modern interiors. Absolute water resistance — the material does not absorb water, swell, or deform even with prolonged direct contact with moisture, allowing use in rooms with high humidity: bathrooms, toilets, kitchens, laundries, pools. The hygroscopicity of the material is less than 0.5%, which excludes the formation of mold and fungi even in humid environments.

Impact-resistant polystyrene wall moldingDemonstrates high resistance to ultraviolet radiation — special UV stabilizers are included in the material composition, preventing destruction of the polymer molecular structure under sunlight exposure. The profile does not yellow, fade, or lose mechanical strength even when installed opposite south-facing windows with intense sunlight. Service life exceeds 15-20 years with proper use and maintenance.

Temperature stability allows using the product in a wide temperature range from -40 to +70°C without changes in physical properties or geometric parameters. The profile does not deform under seasonal temperature fluctuations, which is especially important for rooms with irregular heating — country houses, cottages, technical and auxiliary rooms. The coefficient of thermal expansion of polystyrene is 6-8×10⁻⁵ 1/°C, ensuring dimensional stability and preservation of joint seam density under temperature regime changes.

Mechanical strength of the dural polymer is 3-4 times higher than that of ordinary polystyrene foam due to high material density and special manufacturing technology. The profile surface is coated with a protective layer of increased hardness, 0.5-1 mm thick, formed during extrusion and providing additional protection against scratches, chips, and mechanical damage during transportation, installation, and operation. The material is resistant to accidental impacts and pressure, does not crumble during processing and cutting.

Antistatic properties prevent static electricity accumulation on the surface, thus the profile does not attract dust and airborne contaminants. This ensures longer preservation of cleanliness and aesthetic appearance of decorative elements, reduces the frequency of required cleaning. Biological inertness — the material is chemically neutral, not a nutrient medium for microorganisms, mold, fungi, bacteria. Polystyrene does not emit harmful substances, has no odor, is completely safe for human health and pets, confirmed by sanitary-epidemiological certificates.

Variety of Applications in Interior Design

polystyrene molding on the wallD40V2 opens up limitless possibilities for creative space decoration. Creating classic wall panels — the most popular application of moldings in traditional interiors. Profiles are installed on walls as rectangular or square frames, within which contrasting wallpapers, decorative paint of another shade, Venetian plaster, or fabric covering are placed. This solution visually structures the space, gives walls volume and depth, creates an atmosphere of aristocratic European interior.

Horizontal zoning of walls using molding allows visually altering the proportions of the room. The profile installed at a height of 90-120 cm from the floor divides the wall into two parts: lower panel and upper part. The lower zone is traditionally finished with a darker and more practical material (wooden panels, washable wallpapers, decorative plaster), protecting walls from dirt and mechanical damage from furniture. The upper part is made light and decorative, visually increasing ceiling height and creating a sense of spaciousness.

Framing architectural elements — door and window openings, arches, niches, bay windows, fireplace portals — gives them a finished elegant look. Molding emphasizes the geometry of the opening, making it a striking interior accent, creating visual depth. Double or triple framing using moldings of different widths creates a multi-level molding effect and enhances the decorative effect. Framing mirrors, paintings, photographs, decorative panels, and wall sconces using molding creates the effect of expensive picture frames at minimal cost.

Separation of different finishing materials — an important functional task of moldings. Joints between wallpapers and paint, paint and decorative plaster, different types of wallpapers can be beautifully finished with a profile that hides the technological seam and turns it into a decorative element. Molding allows combining materials of different thicknesses and textures without visible transitions. Vertical accents are created by installing parallel vertical moldings at a distance of 15-30 cm from each other, imitating columns or pilasters, visually increasing the height of the room.

Ceiling decoration — using molding as an alternative to traditional ceiling molding. Profile D40V2, thanks to its expressive shape, creates an impressive ceiling frame, emphasizing the geometry of the room. Molding can be combined with corner elements, outlets, creating complex multi-level compositions. Protective function — installing molding at the height of chair, sofa, and bed backs protects walls from damage and dirt caused by contact with furniture, which is especially relevant for hallways, corridors, dining rooms, children's rooms.

Professional Installation of D40V2 Molding

If you decidedbuy polystyrene moldingFor interior decoration, it is important to know all aspects of proper installation. Installation of D40V2 molding does not require special professional skills and can be performed independently by following the technology. The preparatory stage begins with careful preparation of wall surfaces. The base must be clean, dry, strong, and relatively flat — allowable unevenness should not exceed 5-7 mm per linear meter.

Significant wall defects — cracks, dents, level discrepancies — must be eliminated by spackling and subsequent sanding. Loose crumbling areas are strengthened with deep-penetration primer in two to three layers with intermediate drying. Old wallpaper, peeling paint, grease stains, and dust must be completely removed, as they impair adhesive bond. After mechanical cleaning, the surface is vacuumed or wiped with a damp cloth and primed with acrylic primer if necessary to improve adhesive bond.

Marking — a critically important stage determining the quality of the final result. For horizontal lines, a laser or water level is used, ensuring perfect horizontal alignment along the entire wall. A chalk line or long ruler is used to draw a reference line along which installation will be performed. When creating decorative panels, a detailed scheme on millimeter paper with precise dimensions of all elements is first prepared, then transferred to walls using a pencil, level, and tape measure.

It is important to maintain symmetry — if panels are placed symmetrically relative to the center of the wall, the central axis must first be found, then equal distances should be marked to the left and right. When creating multiple panels of the same size, the distances between them must be strictly equal. Using a construction square to check right angles is mandatory — even a slight deviation from 90° will be noticeable to the eye and spoil the overall appearance.

The adhesive for installation must be specialized for polystyrene — universal polymer-based construction adhesives without organic solvents. The optimal choice — acrylic adhesives in tubes for construction guns, such as Moment Super Strong, Titan Wild, Quelyd Mastifix. Adhesives containing acetone, toluene, gasoline, and other solvents are absolutely unsuitable, as they destroy the polystyrene structure. The adhesive is applied to the back of the profile in dots or dashed lines with a 8-12 cm spacing, leaving 1.5-2 cm from the edges to prevent excess squeezing out.

After applying the adhesive, the profile is pressed against the wall along the marked line and evenly pressed along its entire length. The pressure should be sufficient for the adhesive to contact the wall surface, but not excessive to avoid deforming the profile or squeezing out all the adhesive. The profile is held pressed for 30-60 seconds until the adhesive begins to set. To ensure secure fixation during full drying (12-24 hours), painter’s tape is applied over the molding and fixed to the wall. After the adhesive dries, the tape is carefully removed at an acute angle to avoid damaging the surface.

Cutting and Corner Joints

Questionhow to cut polystyrene moldingWhat tools are needed for cutting corners? A professional miter saw is an essential tool for precise cutting at the required angle. For standard internal 90° angles, each of the two profiles to be joined is cut at a 45° angle. When installing the profile into the miter saw, correct orientation is crucial: the front face should face you, and the side that will be attached to the wall should press against the side wall of the miter saw.

How to cut polystyrene moldingFor internal angles (room corner), the right profile is cut with the saw blade moving from left to right, and the left profile from right to left. For external angles (projecting angle, column), the cutting direction is mirrored. It is recommended to practice on scraps before cutting main elements to avoid mistakes. After cutting, all ends are processed with fine sandpaper grit 180-240 to remove burrs and achieve a perfectly smooth surface, ensuring tight fitting of parts without gaps.

After cutting, all ends are sanded with fine sandpaper of grit 180-240 to remove burrs and achieve a perfectly smooth surface, ensuring tight fitting of parts without gaps.

A small amount of adhesive is applied to the ends when joining corner elements. The parts are carefully aligned according to the relief pattern and pressed together. Any excess adhesive is immediately removed with a damp sponge before it sets. The corner joint is additionally secured with painter's tape crisscrossed until the adhesive is fully dry. If minor gaps of up to 1-2 mm are detected after drying, they are filled with white acrylic sealant. Wider gaps indicate cutting inaccuracies — such joints are better reworked to ensure a high-quality result.

Final finishing and painting

After completing the installation of all elements and allowing the adhesive to fully dry (typically 24 hours at 18-22°C and normal humidity), final finishing work begins. All joints between adjacent profiles and corner joints are carefully inspected for gaps. Even minimal gaps are filled with white acrylic sealant, which has an elastic consistency, good adhesion to polystyrene, and does not shrink upon drying.

Sealant is extruded from the tube in a thin bead directly into the gap, then smoothed with a damp rubber spatula or finger dipped in soapy water. Movements should be smooth and confident to ensure the sealant evenly fills the entire joint space. Excess material is immediately wiped away with a damp sponge before it sets. After the sealant has fully dried (typically 12-24 hours depending on layer thickness and room conditions), all joints are sanded smooth with fine-grit sandpaper (220-240 grit) until perfectly smooth, making the joints completely invisible.

Buy polystyrene molding for wallCan be used in its original white color, which is a classic solution for most interiors. However, painting opens up additional design possibilities and allows moldings to be perfectly integrated into the room’s color scheme. Only water-based paints are suitable for polystyrene: acrylic, water-emulsion, latex, or water-dispersed paints. Organic solvent-based paints are strictly prohibited, as they cause deformation and dissolution of polystyrene.

Before painting, it is advisable to prime the surface with acrylic primer, which improves paint adhesion, equalizes the material’s absorbency, reduces paint consumption, and ensures a more uniform finish. Primer is applied in a thin layer with a brush or mini roller and dried according to the manufacturer’s instructions (typically 2-4 hours under normal conditions). Painting is done in two to three coats with intermediate drying of each layer for 4-6 hours. The first coat is applied thinly to establish a base, while subsequent coats are applied more densely to achieve a rich color and even coverage without streaks.

Color solutions and decorative effects

Polystyrene moldingD40V2 offers wide possibilities for color styling. White moldings on white walls create an elegant monochromatic interior in Scandinavian or minimalist styles, where form is more important than color, and emphasis is placed on relief, play of light and shadow, and surface volume. White moldings on colored walls — a classic solution — highlight the room’s architecture, create a clear structure, and visually expand the space.

Moldings in wall color create a bas-relief effect, where decorative elements stand out solely through relief without color contrast. This solution appears refined and modern, suitable for neo-classical and contemporary interiors. Contrasting combinations — dark moldings on light walls or vice versa — create a graphic, expressive interior with clear lines and accents. Colored moldings — bright or pastel shades — transform profiles into independent art objects.

Metallic finishes (gold, silver, bronze, copper, patina) add luxury and grandeur to classical palace-style interiors. Special decorative techniques include patination (applying dark paint to recessed relief areas), dry brushing (highlighting raised parts with light paint), gradient coloring, and using pearlescent and metallic paints to create special lighting effects.

Combination with interior styles

Molding D40V2, due to its classic shape and medium size, fits organically into various stylistic directions. In classical style, it is used to create traditional wall panels, fireplace, door, and window trim. Neoclassicism allows for more flexible use — accent walls, selective application. Modern styles (minimalism, contemporary, Scandinavian) use moldings for geometric compositions and zoning. Provence and country styles suggest pastel coloring and an aged effect.

Care and longevity

Molding requires no complex maintenance — regular dry cleaning with soft cloth and periodic wet cleaning with mild cleaning agents. Mechanical damage can be locally repaired with putty and touch-up paint. Repainting allows updating the interior without replacing elements. Service life exceeds 15 years with proper use.

Economic Advantage

The cost of polystyrene moldings is 40-60% lower than equivalents made of polyurethane and plaster. Lightweight design reduces transportation costs. Easy installation allows DIY completion, saving on professional services. Durability and low maintenance minimize operational expenses. The ability to repaint multiple times extends the product’s service life.
