CROSprime® Polymeric Primer elevates surface preparation with its advanced polymeric formula, engineered to
maximize adhesion and
extend the lifespan of cementitious coatings. Trusted by professionals, this primer adapts to diverse substrates, ensuring a robust base for
epoxy floors,
render systems,
tiles, and
waterproofing membranes.
Why Choose CROSprime®?
- Unmatched Bonding:
- Deep Penetration: Seals porous surfaces (concrete blocks, bricks) and strengthens weak substrates (AAC, old concrete).
- Rapid Drying: Achieve a tack-free surface in 1–3 hours, accelerating project timelines.
- Versatile Dilution: Adjust mix ratios (1:1 or 1:2) for optimal absorption based on substrate porosity.
- Broad Applications:
- Indoor/Outdoor: Ideal for garages, patios, warehouses, and façades.
- Surface Types: Concrete floors, walls, AAC blocks, refurbished surfaces.
- Coatings Compatibility: Prepares surfaces for epoxy, polyurethane, tiles, and renders.
- Ease of Use:
- Simple Application: Apply with a brush, broom, or roller.
- No Overcomplication: Undiluted for flooring compounds; diluted for walls/porous substrates.
Technical Excellence:
- Mixing Ratios:
- Porous & Strong Surfaces (bricks, concrete blocks): 1 part primer + 1 part water.
- Porous & Weak Surfaces (AAC, aged concrete): 1 part primer + 2 parts water.
- Flooring Compounds: Use undiluted for maximum adhesion.
- Coverage: Varies based on porosity (approx. 5–10m² per liter).
Surface Preparation:
- Clean: Remove dust, grease, and contaminants via mechanical methods (shot blasting, grinding).
- Dry: Ensure substrate moisture <75% RH (per ASTM F2170).
- Prime: Apply evenly; allow drying before second coat (if needed).
