Surface preparation

Remove as much oil as possible by scraping or grinding. Clean the surface with a degreasant. It is important to rinse all traces of the cleaner away and allow the surface to dry. If using a solvent based cleaner, follow the supplier’s Instructions but, again, all traces should be removed.

The floor surface should preferably be dry, but slight traces of residual dampness can be tolerated. If preparing timber, use a suitable cleaner recommended for the purpose and follow the supplier’s Instructions.


Open the inner tins carefully and pour all of the contents of both the resin and curing agent tins into the clean, empty outer tin. Mix thoroughly with a wide bladed stirrer. Scrape the bottom and sides thoroughly to ensure no unmixed material remains. Decant the mixed product into another vessel (or a paint tray, if applying by roller) and apply to the prepared surface.


Do not apply at temperatures below 10°C. Apply one good coat of Flowcrete Oil Block Primer to the prepared surface and allow it to dry.

Application by brush is preferable, because it allows the primer to be worked into the surface, but if applying by roller, use a medium pile roller, working it backwards and forwards to encourage penetration into the surface.
