Sika Sikabond PVA+ is a quick-drying adhesive, sealer, bonding agent, and cement admixture for construction and building tasks.

Who This Product Is For

This product suits builders, plasterers, and other construction professionals working with plaster, screeds, and cement-based materials. It also serves serious DIY users undertaking renovation or repair projects involving bonding, sealing, or surface preparation.

It is appropriate for tasks such as bonding new plaster to existing surfaces, sealing walls before painting or tiling, priming absorbent substrates, and improving cement or mortar mixes.

Key Features

• Functions as an adhesive, sealer, bonding agent, and cement admixture
• Bonds with wood, textiles, cork, paper, and other porous materials
• Seals surfaces to reduce dust and provide a stable base for finishes
• Strengthens mortar and plaster mixes when used as an admixture
• Applied with brush, roller, or spreader
• Acts as a primer to improve adhesion on absorbent surfaces

Practical Applications

The Sika Sikabond PVA+ is used for bonding, sealing, and priming in domestic and professional settings:

• Securing new plaster or screeds to existing surfaces without mechanical keys
• Creating a sealed base for painting or tiling
• Mixing with wood shavings or plaster for internal filling and patching
• Improving workability and durability of cement renders as an admixture
• Dust-proofing internal walls or surfaces

How This Fits Into a Typical Job

This product is typically used during surface preparation and bonding stages. First, diluted PVA+ is applied as a primer to absorbent surfaces. Once tacky, a bonding coat helps adhere new plaster or screed. It can also be mixed into cement or mortar during preparation to enhance the mix’s properties.

The sequence involves cleaning the surface, applying primer if needed, applying bonding coat while tacky, then proceeding with plaster, screed, or finish application.

How to Use

1. Surface Preparation
   • Make sure all surfaces are clean, free from grease, and dry before application.
2. Priming Absorbent Materials
   • Dilute one part PVA+ with three to six parts water. Apply evenly and allow to dry.
3. Bonding Coat Application
   • For plaster or screeds, mix one part PVA+ with 0.5 to 2 parts water. Apply while tacky for optimal adhesion.
4. Sealing Non-Absorbent Surfaces
   • Prime using the same dilution ratio as above. Once dry, proceed with painting or tiling.
5. Patching or Screeding
   • When applying mortars or screeds, make sure the bonding coat remains tacky and use a gauging trowel to mix and apply the material. Reapply the bonding coat if necessary.
6. Cement Admixture
   • Replace 10-15 litres of gauging water with an equivalent amount of PVA+ per 50 kg of cement.

For finishing and smoothing plaster or screeds, use a suitable plastering trowel to achieve an even surface. A soft-grip plastering trowel gives better control when levelling the bonding coat.

Storage and Maintenance

• Store in a cool, dry place away from direct sunlight
• Clean brushes and tools immediately after use with clean water
• Keep the container tightly sealed when not in use
