Product Details

Key Performance Features

• Deep Penetrating Power: Unlike surface-level water-based coatings, our solvent-based formula soaks deep into the pores of concrete and masonry, locking down dust and creating a solid, cohesive surface.

• Rapid Curing: Engineered for efficiency, it becomes touch-dry in just 1–2 hours (depending on ambient temperature), allowing contractors to apply the final waterproofing layer the same day and accelerate project timelines.

• Superior Adhesion Promoter: significantly enhances the bond strength between the substrate and bitumen-based waterproofing membranes (liquid or sheet), preventing peeling and delamination.

• Anti-Corrosive Protection: When applied to metal, it acts as a robust barrier against oxidation, preventing rust formation on iron and steel surfaces.

• All-Weather Resilience: Once cured, it is resistant to rain, UV exposure, and thermal cycling, ensuring the base layer remains intact even during installation delays.

Areas of Application

This versatile primer is the industry standard for preparing surfaces before the application of bitumen-based materials:

• Concrete Roofs & Foundations: Primes porous concrete, screeds, and masonry before applying torch-on membranes or liquid bitumen coatings.

• Metal Roofing & Piping: Protects metal surfaces and provides a “key” for waterproofing tapes or coatings.

• Old Bituminous Surfaces: Rejuvenates and prepares aged bitumen for over-coating.

• Timber & Wood: Seals and primes wooden substrates in roofing structures.

• Damp Proof Course (DPC): Used as a simple, effective primer for DPC applications.

     Application Guidelines

1. Preparation: Ensure the surface is clean, dry, and free of loose debris, oil, or grease.

2. Method: Apply evenly using a stiff brush, roller, or airless spray equipment. Scrub the primer well into porous surfaces to maximize penetration.

3. Coverage: Approximately 4–6 m² per liter (depending on surface porosity).

4. Drying: Allow to dry until the surface is tack-free (1–2 hours) before applying the next layer.

Why Use a Solvent-Based Primer?

Skipping the primer is the #1 cause of waterproofing failure. Our Solvent-Based Bituminous Primer offers distinct advantages over water-based alternatives:

• Better Penetration: Solvents carry the bitumen deeper into the concrete capillaries.

• Faster Drying: Evaporates quicker than water in humid conditions.

• Stronger Grip: Binds dust particles more effectively, ensuring your expensive waterproofing membrane doesn’t detach.
