Multi-Purpose Water Resistant PVA - Biokil Crown

Biokil Crown Water Resistant PVA

Multi-Purpose Water-Resistant PVA Adhesive, Sealer & Primer for Building Applications

Biokil Crown Water Resistant PVA is a professional-grade polyvinyl acetate emulsion designed to act as a sealer, primer, bonding agent, and dustproofer for a wide range of construction applications. Its water-resistant formulation offers excellent adhesion and durability, making it ideal for use on porous surfaces such as concrete, plaster, cement screeds, and timber. Suitable for both internal and sheltered external use, this versatile PVA enhances bond strength, controls suction, and improves finish consistency in preparation for plastering, tiling, or painting.

Key Features & Benefits

• Water-Resistant Formula: Offers enhanced moisture resistance for longer-lasting performance on damp-prone surfaces.
• Versatile Use: Functions as a primer, bonding agent, sealer, and general-purpose adhesive.
• Improves Bonding: Enhances adhesion for plaster, render, tile adhesives, and other finishing products.
• Reduces Surface Suction: Controls porosity on absorbent surfaces to achieve uniform finishes.
• Easy to Apply: Ready-to-use or dilutable with clean water depending on application requirements.

Product Details

• Type: Polyvinyl acetate (PVA) emulsion
• Colour: White (dries translucent)
• Packaging: 5L and 25L containers
• Cure Time: Typically 24 hours depending on ambient conditions and substrate

Application Instructions

1. Surface Preparation: Ensure substrates are clean, sound, and free from grease, dust, or flaking material.
2. Priming & Sealing: Dilute with clean water (typically 1:4) and apply with brush or roller to control suction.
3. Bonding Agent: Apply neat or slightly diluted to both surfaces before bringing them together while tacky.
4. Allow to Dry: Dry time varies depending on use — typically 1–2 hours for thin coats; allow 24 hours for full cure.

Limitations

• Not suitable for permanent external exposure or immersion in water.
• Do not use below +5°C or on frozen surfaces.
