Uses: machine workshop floors, and factory, warehouse or garage floors. Watco Oil Penetrating Primer is a two part epoxy primer specially developed to aid adhesion to porous floor surfaces that cannot be thoroughly cleaned.

Suitable for concrete, brick and masonry, and it will also work on timber surfaces.

Not suitable for use on non-porous, previously painted surfaces or metal surfaces.

Not usually suitable for vegetable, animal or synthetic oil residues. It will tolerate slight dampness in the substrate. Free small liquid samples are available for trial purposes. It should be over coated with a suitable coating such as Watco Epoxy Gloss Coat. Coverage approx. 15 – 20m² per 4 litres. Only one coat is normally required.

Surface Preparation
Remove as much oil as possible by scraping or grinding. Clean the surface with a degreasant such as Watco Concroff Supersafe. 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 before applying Watco Oil Penetrating Primer.
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.

Mixing
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 Watco Paint Mixer. 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.

Application
Do not apply at temperatures below 10°C. Apply one good coat of Oil Penetrating 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.
