Instructions for Use

Preparation of Substrates

Ensure the substrate meets British standards and industry regulations. Substrates must be clean, free of dust, oil, grease, moisture, and loose particles. Remove residues of cement, lime, paint, and adhesives. The substrate should be stable, non-deformable, crack-free, and fully cured.

Priming:

• Cement-based screeds: Primer A Eco (Diluted)
• Calcium sulphate-based screeds: Primer A Eco (Undiluted)
• Concretes: Primer A Eco (Diluted)
• Ceramic floors/tiles: Keragrip Eco (Undiluted)
• Flooring grade plywood: Primer A Eco (Diluted)
• Gypsum fibre or fibre-cement panels: Primer A Eco (Diluted)
• Metal substrates: Keragrip Eco (Undiluted)

Preparation

1. Pour 4.5-5.0 liters of clean water into a container.
2. Add a bag of Levelflex Rapid while mixing.
3. Mix with a mechanical mixer until smooth and self-leveling.
4. For larger quantities, use suitable mixers.
5. Let the mixture rest for 2 minutes, then mix briefly again.

Note: Do not add extra water as it may cause shrinkage and reduce performance.
