Bituminous Roofing Primer

High-Adhesion, Fast-Drying Waterproofing Base Coat

Description:

Bituminous Roofing Primer is a high-performance, solvent-based bitumen primer designed to prepare and prime surfaces before the application of bituminous waterproofing membranes, coatings, and roofing systems. Its fast-drying formula deeply penetrates porous substrates, improving adhesion and enhancing the lifespan of the waterproofing system.

Ideal for use on concrete, metal, masonry, asbestos, and timber surfaces, this versatile primer ensures maximum bonding for bitumen-based membranes and coatings. Whether you’re waterproofing a roof, bridge deck, basement, or foundation, Bituminous Roofing Primer provides the perfect base coat to achieve long-lasting, effective protection.

Manufactured with select refined bitumen and blended with premium-grade solvents, the primer offers excellent coverage, deep penetration, and outstanding surface compatibility. It is engineered to resist water, corrosion, and chemicals, ensuring superior durability under the harshest conditions.

Features:

• Fast-Drying Formula – Touch-dry in 1–2 hours depending on temperature.

• Strong Surface Penetration – Seals porous substrates and improves membrane adhesion.

• Multi-Surface Compatibility – Suitable for concrete, metal, wood, masonry, etc.

• Solvent-Based Performance – Ensures better penetration and drying over water-based products.

• Corrosion Resistant – Protects metal substrates from rust and oxidation.

• Weatherproof – Withstands rain, UV rays, and fluctuating temperatures.
