OT Primer – Garage Floor Primer

OT Primer – Garage Floor Primer

A major cause of floor coating failures is oil contamination.
The oil penetrates deep into the concrete, even when the floor is degreased or even mechanically prepared.
Nevertheless no matter how much the surface is prepared, the remaining oil within the substrate will rise and ‘pop’ the newly applied coating or screed.
OT Primer – Garage Floor Primer is a highly specialised twin pack epoxy floor primer.
Formulated to tenaciously adhere to contaminated garage floors impregnated with almost any oil or grease.
These include animal, vegetable, or mineral based oils.
Our unique formulation binds up to 15% water into the resin without any emulsion or bubble formation, enabling application to oil soaked concrete floors immediately after the cleaning of the surface.
Any oil impregnation becomes locked into the substrate, reacting with the OT Primer to draw it down into the capillary pores.

  • Oil Tolerant Epoxy Floor Primer
  • Water-reactive and unparalleled oil binding properties
  • Highly resistant to rear side soaking from both oil and water
  • Ideal for engineering, garage and workshops floors
  • Safe and easy to use
  • Solvent free formulation

OT Primer – Garage Floor Primer Product Details

Since 1991, Polycote have laid thousands of square metres of floor coatings in all types of vehicle garages and workshops and we fully understand the on-going issues caused by the presence of oil within the substrate.

We have helped thousands of customers, many of which were painting their floors on a regular basis, often every three months, with a revolutionary oil tolerant OT Primer – Garage Floor Primer.  The water-reactive and oil binding properties which are highly resistant to rear side soaking from both oil and water, not only offer a tenacious adhesion to contaminated substrate, but also ensure a total seal of the surface.

OT Primer – Garage Floor Primer, and can be applied to both dry and damp surfaces and is suitable for use prior to the application of a Garage floor Paint (Flortex Professional), the repair of garage floors with Cretex OT Mortar Garage Floor Repair or the installation of a new self-levelling screed (Easi-Screed Industrial).

Thorough substrate preparation is essential.
The surface must be free of brittle particles and laitance. Any remains of previous coatings should be removed by means of scabbling, shot-blasting and/or diamond grinding. Oil and grease build up should be removed using high pressure hot water or steam jet, to fully expose the substrate.
Important: Free pores must be exposed to ensure good adhesion to the surface.
All water must be removed from the surface, leaving it damp but not wet. Garage Floor Primer (OT Primer™) may then be applied to the damp surface immediately after cleaning.


Add the whole of part ‘A’ to the whole of part ‘B’ in a suitable container, and thoroughly mix for at least 3 minutes. For best results use a slow speed drill with a mixing paddle, making sure all material from the sides and bottom of the container are thoroughly mixed in.
Ensure thorough mixing as an unmixed product will result in a poor or non-cure situation.


Apply by brush, roller, or squeegee, in one or more continuous applications until the material is absorbed and a film has formed. Make certain that the entire surface is completely covered to prevent oil or water migration. Oil or grease impregnated surfaces are best primed with a paint brush or soft sweeping broom, in order to ensure the primer is worked well into the surface. Allow to fully cure before the application of any further coating.
Whilst this is in fact extremely rare, it is important to note that if contamination is particularly bad, the substrate may require a further coat of Garage Floor Primer (OT Primer).
Re. Self-Levelling Cementitous Screeds. Should the intention be to pour a cementitous screed (Polycote Easi-Screed) over the primer, then it is important to broadcast kiln dried sand over the primer to ensure an intercoat adhesion is achieved between the primer and the screed.
Ensure Aggregate should be sprinkled evenly over the OT Primer whist it is still WET, at a rate of 1kg per m². (Spiked shoes may be worn to avoid disturbing the wet coating).
Allow to cure for a further 24 hours before removing any loose / excess aggregate from the surface, which is then ready to receive the desired Easi-Screed product.
Where dampness and/or oil contamination is of particular concern, it is advisable to seal the surface completely with one first coat of Garage Floor Primer (OT Primer) and then to lay a second coat onto which the aggregate would then be applied. The reason for this is to ensure there is no ‘bleed through’, should any particles of aggregate penetrate the primer. (Whilst any such penetration is in fact extremely unlikely, some companies with strict requirements / constraints prefer the certainty of a 100% seal, prior to any aggregate being applied).
Should time constraints be limited, it is worthy to note that we do have a faster curing version of the Garage Floor Primer (OT Primer) – see Garage Floor Primer XFH (OT Primer XFH).
