Why Choose Colorex BLOCKA Insulation Paint?

Colorex BLOCKA offers multiple advantages for your interior painting projects:

• Odor Blocking: Effectively seals in strong odors from walls and ceilings, ensuring a fresh indoor environment.
• High Washability: Achieves a Class 1 washability rating (EN 13300), making surfaces easy to clean and maintain.
• Versatile Application: Functions as an insulation paint, primer, and top coat on wood, concrete, plaster, chipboard, and fibreboard.
• Fully Matt Finish: Delivers a uniform, low-reflection matt surface with excellent coverage and richness.

Colorex BLOCKA is an alkyd-based paint, known for its excellent durability and adhesion, making it ideal for challenging surfaces. It’s especially effective for repainting previously distempered or lime-washed walls and ceilings where water-borne materials are not suitable. Beyond its insulating properties, it blocks strong odors, ensuring a clean, fresh atmosphere in any room.

Achieve a professional, fully matt finish with Colorex BLOCKA. With a high coverage of 4–6 m²/L, it often requires fewer coats, saving you time and material. The paint’s formulation ensures a low light reflection (Gloss 3), preventing a patchy appearance and providing a consistent, elegant look. Using isoparaffin as a solvent makes this paint almost completely odorless, even during indoor application, improving comfort for the painter and occupants.

This versatile product serves as both a primer and a top coat, simplifying your painting process. Whether you’re insulating knots in wood or preparing a wall for its final finish, Colorex BLOCKA provides a strong, even base and a beautiful, durable top layer.

Usage

Always read the label instructions before starting. Ensure the air and surface temperature is at least +5°C.

• Pre-painting: Ensure the surface is clean, firm, dry, and dust-free. Brush or scrape away loose old paint. Sand previously glossy surfaces. Protect floors and furniture. Stir the paint well from the bottom before use.
• Painting: Apply the ready-to-use product with a roller or brush. For spraying, dilute with white spirit (preferably aromatic-free). When insulating knots, apply a thin first coat, let dry for 14–18 hours, then apply a second coat. To achieve an even, concealing surface, pull the roller in the same direction at a consistent speed and pressure while the paint is still wet. One coat is usually sufficient, but two may be necessary in some situations.
