TAL - Keycoat Latex Adhesion Primer - 1L

TAL Keycoat Latex Adhesion Primer (1 Litre) is a high-performance synthetic latex-based primer specially formulated to enhance the bond between cementitious materials and smooth, dense, or difficult substrates. This professional-grade product creates a strong, flexible, and durable interface that ensures superior adhesion of new screeds, plasters, or tile adhesives to existing concrete, power-floated surfaces, and other low-porosity backgrounds.

Engineered for demanding tiling and flooring applications, TAL Keycoat effectively improves adhesion, flexibility, and water resistance in both interior and exterior installations. It is particularly suitable for use in high-moisture areas such as bathrooms, showers, and kitchens, helping to prevent debonding, lifting, and cracking caused by moisture ingress or substrate movement.

The product is easy to mix and apply, either as a primer coat or as a slurry bonding layer when combined with ordinary Portland cement. Once cured, TAL Keycoat creates a tough, chemical-resistant film that enhances the mechanical bond and long-term durability of the applied materials.

Key Features & Benefits

• Superior Adhesion: Promotes strong bonding between new and existing cementitious surfaces.

• Enhanced Flexibility: Reduces cracking and delamination on rigid or high-movement substrates.

• Water & Chemical Resistance: Improves resistance to damp and moisture exposure.

• Multipurpose Application: Can be used as a primer, bonding agent, or additive to adhesives and screeds.

• High Durability: Ensures long-lasting results even in high-traffic or wet environments.

• Easy to Apply: Simple brush or roller application with consistent coverage.

Typical Uses

• As a bonding primer between new plaster, screed, or tile adhesive and old or smooth concrete surfaces.

• For priming dense, non-porous substrates such as power-floated concrete and terrazzo.

• As an additive to cementitious mixes to improve adhesion, flexibility, and workability.

• Ideal for wall and floor applications in both residential and commercial settings.

Application Instructions

1. Surface Preparation:
   Ensure the substrate is clean, sound, and free of dust, oil, grease, or loose materials.

2. Mixing (for slurry coat):
   Mix TAL Keycoat with ordinary Portland cement at a 1:2 ratio (by volume) to form a smooth slurry.

3. Application:
   Apply the slurry to the substrate using a brush or roller while still wet, then immediately place the new screed, plaster, or adhesive.

4. Drying Time:
   Allow sufficient curing time before applying subsequent layers or tile adhesives.
