Watco Oil Block Primer is a two part epoxy primer specially developed to aid adhesion to porous floor surfaces that have become soaked with oil. It is suitable for concrete, brick and masonry and it will also work on timber surfaces. It is not suitable for use on non porous, previously painted surfaces or metal surfaces.
Grease and oil should be removed from the surface of a floor before priming, using a degreaser. The Watco Oil Block Primer then works by penetrating the surface with solvent, sealing in soaked-in oil contamination. This also helps to bind together weaker surfaces.
Watco Oil Block Primer is intended for mineral oil residues such as motor oil or cutting oils. It is not usually suitable for vegetable, animal or synthetic oil residues.
Watco Oil Block Primer is intended to be overpainted with epoxy floor coatings, but it can be used with many types of floor coatings.
Remove as much oil as possible by scraping or grinding.
Clean the surface with a degreasant such as Watco Concroff. 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 Block Primer.
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 such as a wooden batten or better still, use a 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.
Do not apply at temperatures below 10°C.
Apply one good coat of 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.
Watco Oil Block Primer can enable a successful floor coating under conditions of deep seated oil contamination that would otherwise be difficult to prepare thoroughly, but it should not be seen as a substitute for good preparation.
It is not suitable for use on non porous, previously painted surfaces, or metal surfaces. It is intended for mineral oil residues – not usually suitable for vegetable oil residues.
Do not overcoat with floor coatings that will be softened by oil, such as conventional single pack floor paints or most water based acrylic paints.
Watco Oil Block Primer will not provide a wearing surface – it requires overcoating with a suitable floor coating.
Contains solvent. Use only in well ventilated areas.
