White surface for painting opens up endless possibilities for color decoration. Unlike pre-painted items,decorative molding for paintingallows selecting the ideal shade that harmoniously fits the existing color scheme of the room. You can maintain the classic white color, choose pastel tones, or paint in vibrant hues — all depends on the design concept.

High-density polystyrene as a modern material

The base of molding D22 is high-density polystyrene, also known as duro-polymer or fitopolymer — a modern composite material of the latest generation. This material is produced by extrusion at high temperatures followed by pressure treatment, creating a dense, homogeneous structure with unique performance characteristics. The material density significantly exceeds that of ordinary expanded polystyrene, ensuring high mechanical strength and product longevity.

High-density polystyrene has several advantages over traditional materials. It is completely moisture-resistant, makingpolystyrene moldingan ideal choice for rooms with high humidity — kitchens, bathrooms, and toilets. The material does not rot, is not a nutrient medium for mold and fungi, and is not attacked by insects. This guarantees the preservation of the product's original appearance for decades of use.

The temperature stability of polystyrene ensures the preservation of the profile's geometry within temperature fluctuations ranging from -40 to +70°C. The material does not deform when heated by radiators or cooled in unheated rooms. The coefficient of thermal expansion is minimal, preventing gaps at joints during seasonal temperature changes. The molding retains its ideal shape regardless of operating conditions.

The ecological safety of modern polystyrene is confirmed by international certificates. The material does not emit harmful volatile compounds at normal temperatures, has no odor, and is completely safe for human health.HI WOOD Polystyrene MoldingIt is permitted for use in residential spaces of all categories, including children's rooms, bedrooms, and kitchens. The material is hypoallergenic and does not cause irritation even for people with heightened sensitivity.

Profile geometry and design solutions

Profile dimensions 22 × 10 mm represent an optimal combination for creating elegant decorative compositions. The 22 mm height creates sufficient relief for light and shadow play, giving the molding volume and expressiveness. At the same time, the profile does not appear bulky, preserving the lightness and elegance of lines. This height is ideal for rooms with standard ceiling heights, where larger profiles might visually overload the space.

The 10 mm thickness provides sufficient mounting surface area for secure attachment of the molding to walls or ceilings. At the same time, the profile remains lightweight — one linear meter weighs only about 100 grams, which is several times less than similar products made of MDF or wood. The low weight significantly simplifies installation and allows mounting the molding even on gypsum board structures without risking deformation of the base.

The profile shape is executed in a classic style with smooth lines and elegant relief. The front surface has a characteristic curve, creating a soft play of light and shadow. The clarity of the relief is achieved through a high-precision manufacturing process — extrusion under computer control. Each plankmolding D22has identical geometry with deviations not exceeding 0.1 mm, ensuring flawless element alignment during installation.

The plank length of 2000 mm is chosen considering the optimal balance between practical use and transportation convenience. Two molding planks cover a wall 4 meters long, corresponding to typical room sizes in modern apartments. If needed, the molding can be easily cut with a fine-toothed saw or a construction knife, allowing adaptation to any size and space configuration.

Installation technology of polystyrene moldings

Installation of molding D22 from polystyrene is simple and does not require special professional skills. The material's lightness allows for self-installation without helpers. Surface preparation includes cleaning from dust, dirt, and oily contaminants. The surface must be dry and degreased. Large irregularities are recommended to be leveled with putty, but polystyrene molding, due to some elasticity, can compensate for minor base defects.

For mountingpolystyrene moldingSpecial mounting adhesives based on acrylic or polymer are used. It is absolutely not recommended to use adhesives based on organic solvents — they may damage the polystyrene structure. Optimal are acrylic adhesives such as liquid nails, MS-polymer-based sealants, or specialized polystyrene compositions. The adhesive is applied in dots or dashed lines to the back of the molding with an interval of 10–15 cm.

After applying the adhesive, the molding is pressed against the surface and firmly held for several seconds. Due to the low weight of the product, the adhesive sets quickly, and additional fixation is usually not required. Excess adhesive protruding at the edges is immediately wiped off with a damp sponge before it dries. Some professionals recommend using painter’s tape for temporary fixation until the adhesive fully sets, especially for ceiling installations.

Corner joints are made by beveling ends at a 45-degree angle. Polystyrene cuts exceptionally well with a standard construction knife with replaceable blades or a fine-toothed saw. For precise angles, a miter box is recommended. The joint is filled with acrylic sealant, which is sanded smooth with fine-grit sandpaper after drying. A correctly executed corner joint becomes practically invisible after painting.

Finishing painting options

The white surface of molding D22 is ideally prepared for painting. The material has a fine-pored structure that ensures good adhesion with water-based paints. For paintingmolding for paintingWater-based acrylic paints are recommended — they are safe, odorless, dry quickly, and create a durable elastic coating. Paints based on organic solvents are not recommended, as they may damage polystyrene.

Classic white coloring highlights the elegance of the profile and creates the effect of traditional plaster molding. To achieve a perfectly white surface, apply 1–2 layers of quality acrylic paint. The first layer can be applied with a microfiber roller for even coverage, and the second layer with a brush to detail raised areas. White molding is universal and suitable for any interior style, from classic to modern minimalism.

Colorful coloring allows creating bright accents and unconventional design solutions.decorative moldingIt can be painted in any color from the palette — from pastel soft tones to vibrant saturated shades. Popular contrast solutions include dark molding on light walls or light molding on a dark background. Colored molding can match the color of furniture, textiles, or decorative accessories, creating harmonious combinations in the interior.

Decorative painting techniques offer additional possibilities. Patination involves applying a base light layer followed by dark patina to recesses to create an aged effect. Gilding is performed with metallic pigment paints and adds luxury and elegance to the interior. The ombre technique with a smooth color transition creates a modern artistic effect. Polystyrene surface holds any acrylic paints and decorative compositions perfectly.

Areas of application in interior design

Wall compositions using molding are one of the most popular decoration methods.Molding HI WOOD D22It is ideal for creating framed panels of various sizes and configurations. Rectangular frames on walls visually structure the space, create rhythm, and add architectural expressiveness. The interior of the frames can be painted in a contrasting color, covered with patterned wallpaper, or left to match the wall color.

Molding around door and window openings gives them a finished, elegant look. Molding conceals technological gaps between the frame and the wall, creates a visual frame, and protects corners from mechanical damage. The lightness of polystyrene makes it ideal for arched openings, where molding can follow the arch’s curve due to the material’s slight flexibility when slightly heated.

Ceiling moldings made from D22 molding create a smooth transition between wall and ceiling. Installed along the room’s perimeter, molding visually lifts the ceiling and makes the room appear more proportionate. A LED strip can be hidden behind the molding to create a floating ceiling effect — one of the trends in modern design. The lightness of polystyrene allows installing moldings even on suspended ceilings without risking deformation.

Zoning space with horizontal moldings allows visually altering the proportions of the room.polystyrene moldingInstalled at one-third the height of the wall, it divides the wall into two zones with different finishes. This classic technique is suitable for hallways, corridors, and dining rooms. Several parallel moldings create a dynamic rhythmic structure.

Decorating furniture with molding transforms ordinary items into designer objects. Cabinet facades adorned with polystyrene molding appear like expensive classic furniture. The material’s lightness allows attaching molding directly to furniture facades without risk of detachment. Headboards, doors, panels — molding adds extra decorative appeal everywhere.
