Sika Waterproof PVA, available to buy at HSS, is a specially formulated vinyl acetate polymer designed for exterior applications. The 5-litre waterproof adhesive and sealer is perfect for a variety of construction tasks, in both indoor and outdoor environments.

As the PVA is specially formulated for use in exterior conditions, it ensures reliable adhesion and sealing. Unlike standard PVA, the waterproof formula will not re-emulsify when exposed to moisture, providing lasting protection and strength. It is ideal for priming, sealing, waterproofing and toughening surfaces such as brickwork, mortar, screed, render and plaster.

Applying the PVA is straightforward, which makes it suitable for both professional and DIY projects.
