Who This Product Is For

This product is suitable for both domestic users undertaking home improvement projects and professional tradespeople working on construction or renovation jobs.

It can be used for tasks ranging from basic repairs and surface preparation to more involved building work involving concrete, plaster, or screed applications.

Key Features

• Multi-purpose formula functions as adhesive, sealer, primer, and bonding agent
• Economical solution with good coverage that reduces material waste
• Fast drying properties speed up project timelines
• High bond strength between porous and non-porous surfaces
• Suitable for use with wood, plaster, concrete, tiles, and other materials
• Acts as an effective admixture for stronger cement mixtures

Practical Applications

The Sika Sikabond PVA+ is suitable for various domestic and professional projects:

• Securing cement screeds, render, or plaster to surfaces like stone and brick
• Sealing dusty floors or applying as a primer to prepare walls for painting
• Acting as an internal filler when combined with plaster or sawdust
• Binding new screeds or concrete layers to existing ones without surface preparation
• Serving as an adhesive for wood, textiles, cork, and paper in everyday repairs

How This Fits Into a Typical Job

This product is typically used during surface preparation and bonding stages of construction or renovation work. It prepares surfaces for subsequent applications like plastering, tiling, or painting by improving adhesion.

It fits into workflows where surfaces need priming before finishing treatments, or where materials need bonding together before further construction stages proceed.

How to Use

1. Surface Preparation:
   • Clean the surface thoroughly, removing dust, grease, or loose particles
2. Priming Absorbent Surfaces (e.g., Concrete or Plaster):
   • Dilute one part PVA+ with three to six parts water and apply evenly. Allow it to dry before proceeding
3. Bonding Coat Application:
   • Mix one part PVA+ with 0.5 to two parts water. Apply while still tacky, then add plaster, cement, or screed
4. Sealing Non-Absorbent Surfaces (e.g., Paint or Tiles):
   • Prime the surface as above, let it dry, and proceed with painting or tiling
5. Using as a Cement Admixture:
   • Replace 10-15 litres of gauging water with PVA+ for every 50kg of cement to enhance cohesion and bonding strength
6. Internal Patching or Screeding:
   • Apply the bonding coat and add mortars, screeds, or renders while tacky. Reapply if the bonding coat dries prematurely

Storage and Maintenance

• Store the tub in a cool, dry place away from direct sunlight to maintain product integrity
• Clean tools immediately after use with clean water to prevent residue build-up
• Always reseal the container tightly to avoid contamination or drying out of the product
