MPN: SKPRIMEMB5

Barcode: 7612894379990

This high-performance two-part epoxy primer creates a robust moisture barrier and consolidates substrates for wood flooring applications on various surfaces including cement screeds, concrete, mastic asphalt, and surfaces with old adhesive residues.

Who This Product Is For

This primer is designed for professional flooring contractors and experienced individuals undertaking wood flooring installations. It suits those working on projects where moisture control and substrate preparation are critical considerations.

This product is appropriate for jobs involving new wood flooring installations, refurbishment projects, and situations where substrates require stabilisation or moisture protection before adhesive application.

Key Features

• Moisture Protection: Forms a durable barrier on cement-based substrates with high moisture levels, providing long-lasting performance.
• Substrate Consolidation: Stabilises and strengthens surfaces like concrete and anhydrite screeds for better flooring adhesion.
• User-Friendly Application: Low viscosity allows for effortless spreading by brush or roller, saving time and effort.
• Underfloor Heating Compatibility: Works seamlessly with heated flooring systems without compromising effectiveness.
• Solvent-Free Formula: Provides safer use with minimal odour and environmental impact.

Practical Applications

• Suitable for moisture control on cement screeds with up to 6% CM moisture content.
• Strengthens and stabilises weak or refurbished substrates, ensuring a solid base for flooring installations.
• Encourages adhesion on challenging surfaces, such as mastic asphalt or residual adhesive layers.
• Compatible with both new builds and refurbishment projects, offering flexible use across different environments.

How This Fits Into a Typical Job

This primer is used during the substrate preparation phase, after surface cleaning but before adhesive application. It serves as a moisture barrier and surface consolidator that prepares the substrate to receive wood flooring adhesives.

The product forms part of a system where proper surface preparation leads to successful adhesive bonding. Following the correct mixing and application procedures ensures the primer creates an effective barrier and adhesion-promoting layer.

How to Use

1. Surface Preparation:
   • Clean the surface thoroughly to remove dust, grease, and loose material. Then, make sure the substrate is dry and ready for priming.
2. Mixing:
   • Combine the two components as per the manufacturer’s instructions. Stir well to create a consistent mixture.
3. Application:
   • Apply the primer using a brush or roller, for even coverage across the entire surface.
4. Drying Time:
   • Allow sufficient curing time based on temperature conditions: 12 hours at +20°C, 18 hours at +10°C, or 6 hours at +30°C.
5. Final Check:
   • Once cured, the material will become transparent, indicating readiness for subsequent adhesive application.

Storage and Maintenance

• Store in a cool, dry place away from direct sunlight to preserve product quality.
• Clean tools immediately after use to prevent epoxy residue buildup.
• Avoid prolonged exposure to extreme temperatures to maintain effectiveness.
