Why choose a deep penetrating primer?

Deep penetrating primers are perfect for strengthening your existing surface; the formula will absorb deeply into the surface, effectively reducing its porosity and providing a thorough seal, thus preparing it impeccably for a flawless application of a top coat of paint. Should you have any additional queries regarding specific substrates, please do not hesitate to contact our dedicated sales team on 0330 0570 695, and they will be more than happy to offer you comprehensive and tailored advice.

Please note: the above coverage rates are dependant on the porosity of the surface.




Old paint finishes should be removed if flaking at all and the surface should be sanded to create a texture (also known as a mechanical key) prior to applying Resincoat Deep Penetrating Epoxy Primer. When preparing for a floor coat, doing so mechanically (shot-blasting or grinding) is always advisable for best results, but if that is not possible then sanding the area or our Etch and Clean is a good alternative. After the surface has been completely abraded, thoroughly sweep and vacuum the area of any remaining dust or contaminants. For more information on preparation, please see technical data sheet. 

Please note: Etch and Clean is only suitable for use on bare concrete.



We advise when applying this product the ambient temperature is at least 7°C.

1. Mix Part A on its own with a mixing paddle attached to an electric drill for about 1 minute before adding ALL of Part B and continue to mix for another 90 seconds, keeping the paddle in suspension to avoid mixing air into the unit.

2. Pour entirety of the tin's contents into a plastic paint scuttle or tray.

3. Immediately begin applying your paint with a nylon-bonded resin suitable roller.

4. Use a brush around the edges to cut in (a second pair of hands can be useful for this stage).

5. As soon as the primer has started curing (is no longer tacky to touch) you apply your first coat of paint; this should take 8-12 hours.

6. The cured final coat is ok for foot traffic after 12-24.


PLEASE NOTE: The pot life of this product is 20 minutes. This means that once parts have been mixed, the paint will start to chemically cure after this time. Ensure you remove the paint from the tin in this window. The paint will then be workable on your floor for up to 40 minutes. 

Pot life = Time to harden in pot following addition of hardener

Working Time = Time to apply product before it becomes unworkable



Roller sleeves should be used once per coat, two coats will require two roller sleeves.

This product should NOT be split. Taking smaller quantities from each tin, even if measured correctly, may cause issues with activating.

This product is NOT self levelling.

As standard this product arrives grey, if you require a clear primer you must tell us at the point of ordering.
