Useful Information

Ensure surfaces are clean and dust-free before application.

• As an adhesive: Apply PVA to both surfaces, press together firmly and allow 24 hours to cure.
• As a plaster bonding agent: Prime using 1:2 PVA/water and allow to dry; apply a second 1:2 mix and plaster while still tacky.
• As a cement admixture: Mix 1L of PVA per 5kg of cement (or 5L per 25kg bag).
• As a sealer/primer: Dilute 1:4 PVA/water depending on surface porosity.

Drying time varies with temperature, humidity and substrate. Once dry, PVA films resist oils and greases but may soften with prolonged water exposure.
