Calyco Water Primer (Interior Primer), Brand Name : Calcyo

Calyco Waterproofing Sealer is a high-performance, water-based acrylic elastomeric coating designed to deliver long-lasting waterproof protection for interior and exterior surfaces. Formulated with flexible polymers and UV-resistant additives, it forms a seamless, crack-bridging membrane that blocks water ingress and protects structures from rain, moisture penetration, efflorescence and environmental damage.

The coating offers excellent adhesion to multiple substrates, including concrete, masonry, plaster, cement, brickwork, metal and wood, making it suitable for a wide range of waterproofing applications. Its breathable film technology allows trapped moisture within the substrate to escape while preventing external water from entering, reducing blistering and improving durability.

Calyco Waterproofing Sealer resists fungal and algal growth, ensuring long-term surface cleanliness. Ideal for terraces, parapet walls, basements, planters, retaining walls, wet areas and structural surfaces exposed to moisture. With coverage of 85–110 sq.ft./L/coat and strong crack-bridging ability up to 1 mm, it provides reliable waterproofing performance for residential, commercial and industrial structures.
