Bitumen-Polymer Prime Coating

Ready to use solvent-based polymer-bitumen primer

Description:

Bitumen-Polymer Prime Coating is a high-quality, universal quick-drying primer designed to prepare and protect surfaces before applying bituminous waterproofing membranes, mastics, or coatings. Engineered with advanced polymer-modified bitumen, this product provides excellent adhesion, superior penetration, and outstanding protection against moisture and corrosion.

This bitumen primer is ideal for use on concrete, metal, wood, brick, asbestos cement, and other porous or non-porous surfaces. It forms a strong, durable film that enhances the bonding of waterproofing layers, extending the service life of construction systems in roofing, foundations, basements, bridges, and civil engineering structures.

Whether you are working on commercial, industrial, or residential projects, Bitumen-Polymer Prime Coating ensures reliable surface preparation, faster application, and long-term durability.

Key Features & Benefits

• Excellent Adhesion – Creates a strong bond between substrates and subsequent waterproofing layers.

• Quick Drying – Fast curing formula reduces waiting time before applying membranes or mastics.

• Deep Penetration – Effectively seals porous surfaces, ensuring maximum waterproofing performance.

• Corrosion Protection – Prevents metal substrates from rusting and prolongs service life.

• Universal Application – Suitable for concrete, metal, wood, brick, asbestos cement, and bituminous surfaces.

• Flexible & Durable – Resistant to cracking, aging, and harsh environmental conditions.

• Improves Waterproofing System Performance – Increases the adhesion and longevity of bitumen membranes and mastics.

Applications

Bitumen-Polymer Prime Coating can be used in a wide variety of construction and waterproofing projects:

• Roofing Works – Primer for roll-fed bituminous membranes and liquid-applied waterproofing.

• Foundation Waterproofing – Surface preparation for basement and foundation coatings.

• Bridge Decks & Civil Structures – Reliable adhesion layer for waterproofing and protective coatings.

• Metal Protection – Corrosion-resistant primer for pipelines, steel tanks, and structural steel.

• Concrete & Masonry Surfaces – Seals porous surfaces to prevent water penetration.

• Repair & Maintenance – Restores adhesion on aged or weathered bitumen surfaces.

Technical Data Sheet (TDS)

General Information

Physical & Chemical Properties

Surface Preparation

1. Clean the surface thoroughly, removing dust, dirt, rust, grease, and loose particles.

2. For metal surfaces, ensure rust and scale are removed by wire brushing or sandblasting.

3. Ensure the substrate is dry or slightly damp (no standing water).

4. Stir the primer well before application.

Application Method

• Brush or Roller: Apply evenly across the surface.

• Airless Spray: Recommended for large surface areas for uniform coverage.

• Consumption Rate: 0.25 – 0.35 kg/m² (depending on surface porosity).

• Drying Time: 2–4 hours under normal conditions before applying waterproofing membranes or coatings.

Storage & Handling

• Store in tightly sealed containers in a cool, dry, well-ventilated area.

• Keep away from direct sunlight, open flames, and sources of heat.

• Shelf life: 12 months in original unopened packaging.

• Transport according to flammable liquid regulations.

Health & Safety Precautions

• Use in well-ventilated areas.

• Avoid contact with skin and eyes; wear protective gloves and goggles.

• Do not inhale vapors – wear a mask if working indoors.

• Keep away from children, sparks, and fire sources.

• In case of skin contact, wash immediately with soap and water.

Advantages Over Traditional Primers

• Polymer-modified formulation ensures stronger adhesion and flexibility compared to traditional bitumen primers.

• Faster drying time reduces project delays.

• Better corrosion resistance extends the lifespan of steel and concrete structures.

• Universal application makes it suitable for diverse substrates, unlike standard primers limited to certain surfaces.
