Solvent Based Bituminous Primer

Solvent-Based Bituminous Primer

1. Product Description

PC-Prime® 01 is a high-quality, low-viscosity, solvent-based bituminous primer. It is composed of selected bitumens dissolved in a petroleum solvent to form a penetrating solution.

PC-Prime® 01 is designed to penetrate deeply into porous substrates (concrete, masonry, and timber) to bind dust particles and seal the surface, creating an optimal bonding area for subsequent bituminous waterproofing membranes, coatings, or mastics.

1. Key Features & Benefits
  • Deep Penetration: Low viscosity allows the primer to absorb deep into concrete pores.

  • Adhesion Promoter: Significantly enhances the bond between the substrate and bituminous waterproofing membranes (Torch-on or Self-Adhesive).

  • Dust Binding: Consolidates dusty or friable surfaces.

  • Fast Drying: Rapid solvent release allows for quicker overcoating compared to water-based alternatives.

  • Water Resistant: Acts as a temporary damp-proofing layer once cured.

  • Cost-Effective: High coverage rate reducing project costs.

  • Standard Compliance: Conforms to ASTM D41 (Standard Specification for Asphalt Primer Used in Roofing, Dampproofing, and Waterproofing).

2. Areas of Application

PC-Prime® 01 is suitable for use on vertical and horizontal surfaces in the following applications:

  • Priming concrete roofs prior to the application of Torch-On or Self-Adhesive Bitumen Membranes.

  • Priming foundations and basement walls before applying bituminous coatings.

  • Damp-proofing concrete, masonry, and metal surfaces.

  • Protection of buried steel and pipes.

4. Application Instructions

Surface Preparation:
The surface must be clean, dry, and free from oil, grease, loose particles, and curing compounds. Fresh concrete should be cured for at least 14 days. Metal surfaces should be wire-brushed to remove rust.

Application:

  1. Stir PC-Prime® 01 well before use.

  2. Apply using a brush, roller, or airless spray.

  3. Ensure a uniform coating; do not allow the primer to pool in depressions.

  4. Allow the primer to dry completely (until all solvent has evaporated and the surface is tack-free) before applying the subsequent waterproofing layer.

Coverage Rate:
Approximately 4 to 6 m² per liter, depending on the porosity and texture of the substrate.

5. Packaging & Storage
  • Packaging: Available in 20-liter pails and 200-liter drums.

  • Storage: Store in a cool, dry, well-ventilated area away from direct sunlight and sources of ignition. Keep containers tightly closed when not in use.

  • Shelf Life: 12 months in original unopened containers.

6. Health & Safety
  • Flammability: PC-Prime® 01 contains volatile solvents and is flammable. Keep away from open flames, sparks, and heat sources. No smoking during application.

  • Ventilation: Ensure adequate ventilation when using in enclosed spaces.

  • PPE: Wear protective gloves, safety goggles, and suitable protective clothing.

  • First Aid:

    • Skin: Wash thoroughly with soap and water (do not use solvent).

    • Eyes: Flush with water for 15 minutes and seek medical attention.

    • Ingestion: Do not induce vomiting; seek immediate medical attention.
