Sika Sikabond PVA Plus 25L is a trade-size general-purpose PVA adhesive, sealer, primer, bonding agent and mortar improver for internal building preparation work. It is used for priming, sealing, bonding, dustproofing and improving mortars, renders, screeds and plaster applications on suitable prepared substrates.

The 25 litre drum is suited to contractors, builders, plasterers, decorators, maintenance teams and frequent users who need a high-volume PVA product for repeated internal jobs. It is a practical choice for larger preparation areas, dusty surfaces, absorbent backgrounds and cement-based mixes when used in line with manufacturer guidance.

What This Product Is Used For

This PVA Plus product is used where internal building surfaces need priming, sealing, bonding or improved mortar performance before further work.

• Priming porous surfaces before plastering, painting, tiling or repair work.
• Sealing and dustproofing concrete, masonry, plaster and similar internal substrates.
• Bonding absorbent surfaces before screeds, renders, plaster or patching mortars.
• Improving workability of mortars, renders, screeds and grouts when used as an admixture.
• General-purpose adhesive used on suitable wood, cork, paper, textiles and building materials.
• Bulk internal preparation work for trade refurbishment, maintenance and construction jobs.

Key Performance Benefits

• Trade Size 25L Drum: Suitable for repeated use, large areas and contractor-level internal preparation work.
• Multi-Use PVA Formula: Works as an adhesive, primer, sealer, bonding agent, admixture and dustproofer.
• Surface Preparation Support: Helps control porosity and prepares surfaces for later building or finishing work.
• Mortar And Render Improver: Can improve workability and bonding performance of suitable cement-based mixes.
• Water Clean-Up: Tools and equipment can be cleaned with water immediately after use.

Why Choose This PVA Plus

Choose Sika Sikabond PVA Plus 25L when internal building work needs a bulk primer, sealer, adhesive or admixture for repeated use. It is the correct choice for larger preparation jobs where smaller containers would need frequent replacement.

Compared with smaller PVA tubs, the 25-litre drum is better for contractors and high-use jobs. Compared with waterproof PVA or SBR products, this PVA Plus is best treated as an internal-use product and should not be selected where manufacturer guidance requires an external waterproof bonding system.

How It Fits Into The Job

This product is used during the preparation, bonding or mix-improvement stage before plastering, screeding, rendering, sealing or finishing work.

1. Prepare the surface so the PVA can bond to a clean, stable substrate.
2. Dilute or use neat according to the intended application.
3. Apply before the next trade layer or mix stage as directed by the manufacturer’s guidance.

Quick Use Guide

Use only on suitable substrates and follow the manufacturer’s guidance for dilution ratios, drying time and application method.

• Ensure the surface is dry, clean and free from dust, grease, dirt and loose material.
• Agitate the product before use.
• Apply by brush, roller or spreader.
• For sealing and priming, dilute with clean water as required by the application.
• For bonding absorbent surfaces, apply the bonding coat and complete the next layer while tacky.
• Clean tools and equipment with water immediately after use.

Important Notes

• Recommended for internal use only according to the technical data sheet.
• For external applications, use a suitable waterproof PVA or SBR product where required.
• Not suitable for load-bearing applications.
• Protect from frost and store in correct conditions with the container tightly closed.
• Consumption varies depending on surface porosity, dilution and application method.
• Always follow the technical data sheet and safety data sheet before use.

Safety

Wear safety glasses, protective gloves and suitable work clothing when handling PVA products. Use normal hygiene measures when handling chemical products, avoid unnecessary skin and eye contact, and wash equipment with water before the material dries.
