Barcode: 5029347613372 | Size: 25L Drum | Colour: White (liquid)

This 25L trade-size drum is designed for high-volume use across large-scale construction and site projects. It provides a cost-effective solution for bonding, sealing, and improving cement-based materials where consistent performance is required across multiple applications.

Key Performance Benefits

• Improved Adhesion: Helps create a strong bond between surfaces and applied materials.
• Surface Sealing: Reduces porosity on absorbent substrates before plastering or decorating.
• Enhanced Flexibility: Improves mortar performance and helps reduce cracking.
• Dust Reduction: Helps stabilise surfaces by binding loose particles.

Typical Applications for Large Projects

• Priming walls and ceilings prior to plastering or painting.
• Sealing porous surfaces across large areas.
• Adding to mortar mixes to improve adhesion and workability.
• Surface preparation on commercial and trade sites.

Quick Application Guide

Ensure all surfaces are clean, sound, and free from dust, grease, and loose material before application.

• Priming: Dilute with clean water depending on surface condition and application requirements.
• Admixture: Add directly to mortar or cement mixes as required.
• Application: Apply evenly using a brush, roller kit, or sprayer.
• Drying: Allow sufficient drying time before applying additional finishes.

Helpful Tools

For accurate dilution and preparation, use a paint kettle or suitable mixing container to achieve consistent results.

This PVA sealer and admixture is widely used across construction and renovation projects where reliable bonding, surface preparation, and high-volume application are required.
