Description

Enhance your building and preparation work with SikaBond Waterproof PVA 5L – a versatile, high-performance vinyl acetate bonding agent designed to act as a primer, sealer, adhesive and admixture in one powerful solution.

Formulated specifically for demanding construction environments, this waterproof PVA improves adhesion, strengthens surfaces and protects against moisture, making it ideal for use on brickwork, plaster, concrete, screed and render. Unlike standard PVA, it will not re-emulsify when wet, ensuring long-lasting performance even in damp or external conditions.

Key Features & Benefits

  • Multi-Purpose Formula – Works as a primer, sealer, adhesive and cement admixture
  • Waterproof Performance – Ideal for internal and external use without breaking down in moisture
  • Improves Adhesion – Enhances bonding of plaster, render and screeds to difficult surfaces
  • Strengthens Surfaces – Toughens floors, renders and mortar mixes for durability
  • Will Not Re-Emulsify – Maintains performance even when exposed to water
  • Easy to Apply – Can be brushed, rolled or mixed directly into cement

Typical Uses

SikaBond Waterproof PVA is designed for a wide range of construction and preparation tasks:

  • Priming surfaces before plastering or painting
  • Sealing porous or dusty surfaces
  • Bonding render and screed to existing substrates
  • Adding to mortar mixes to improve flexibility and adhesion
  • Waterproofing and strengthening floors and walls

It’s widely used by builders, plasterers, roofers and DIYers as an essential preparation product.

Suitable Materials

This versatile PVA bonds effectively to:

  • Brick & masonry
  • Concrete & screed
  • Plaster & render
  • Wood & timber
  • Most porous building materials

It is designed to improve bonding where at least one surface is porous, making it highly effective across typical construction applications.

Why Choose Waterproof PVA?

Compared to standard PVA adhesives, SikaBond Waterproof PVA offers:

  • Superior water resistance for external and damp environments
  • Stronger, longer-lasting adhesion across multiple substrates
  • Greater versatility as a 4-in-1 product (primer, sealer, adhesive, admixture)
  • Improved durability of renders and screeds

This makes it a go-to solution for professionals who need reliable performance in all conditions.
