Prim Plus - Adhesion Primer
Prim Plus is a solvent-free water-based adhesion primer made with styrene-acrylic copolymer resins, ideal for smooth, non-absorbent, or closed surfaces such as:
- - Wood
- - Painted surfaces
- - Old tiles
- - Helicopter-polished concrete
This primer is essential for ensuring perfect adhesion between your substrate and the final coating. It enhances surface preparation and ensures compatibility with applied materials, providing a long-lasting, durable result.
Why Choose Prim Plus?
- • Specially Formulated: Designed to adhere to closed, smooth, or challenging surfaces.
- • Versatile Application: Compatible with various substrates, from wood to polished concrete.
- • Enhanced Bonding: Prepares the surface for improved adhesion with decorative finishes.
- • Effortless Preparation: Simplifies the adhesion process for even the most complex surfaces.
How to Determine the Right Primer
Test the surface to determine whether it is porous or closed:
- Place a few drops of water on the surface.
- If the water is absorbed, the surface is porous (use Prim).
- If the water beads up or remains on the surface, it is closed (use Prim Plus).
Application Instructions
- Prepare the Surface: Ensure the substrate is clean, dry, and free of dust or grease.
- Apply the Primer: Using a roller or brush, apply a thin, even layer of Prim Plus to the surface.
- Drying Time: Allow the primer to dry completely before applying the final coating.
Note: For surfaces in wet environments (e.g., showers, sinks, etc.), ensure proper waterproofing is completed beforehand using a waterproof undercoat and fiberglass reinforcement tape for angles.
Technical Specifications
- • Type: Adhesion Primer
- • Color: White liquid
- • Consumption: 1 L per 10–12 m² (varies by substrate porosity)
- • Shelf Life: 12 months in unopened, original packaging stored in a dry, frost-free environment
Pro Tip: Always use Prim Plus for smooth, closed surfaces to ensure flawless adhesion and a professional finish. For porous substrates, switch to Prim Adhesion Primer.
