Each Watco Fine Crack Filler Cold Cure pack contains a tin of curing agent and a separate tin of resin. Add the contents of the curing agent tin to the tin of resin and stir thoroughly with a flat bladed mixer, or a slow speed drill fitted with a paddle. Scrape down the sides and bottom of the tin during mixing to avoid unblended resin/curing agent creating ‘soft spots’ in the cured product.
Pour carefully out of the tin onto and along the line of the crack and level off by using a straight edge or plastic/rubber scraper. Wipe away any excess. Leave to harden for 4 hours at 20°C before coating or overlaying. The repair may be coated with any type of floor paint or high performance coating e.g. Watco Epoxy Gloss Coat.
Please note: Cracks in floors where one side has subsided can also be filled, but it will be impossible under these circumstances to achieve a flush finish. Watco Concrex may be used to make up differences in floor levels.
