BOSTIK EXTERIOR WATERSEAL 5L

Bostik Exterior Waterseal 5l is suitable for brick, stone, slate, terracotta, render and timber to give water resistance and can also help prevent condensation, efflorescence and frost damage. Clear in colour and shouldn’t affect the appearance of the treated surface. Some surfaces may darken very slightly, so carry out a test of a small area first.

Available clear and contains 5 litres.
