Watco has developed a highly advanced formulation that puts Epoxicote High Build into a class of its own. This one coat, high build, virtually solvent free epoxy resin floor coating, guarantees exceptional wear and offers superior protection for concrete floors. The ‘rapid’ versions cure within just 8 hours to withstand light traffic saving on downtime, whilst the ‘anti slip’ versions provide a good level of slip resistance where needed.

All grades now carry CE Mark EN1504-2 and have impressive test results for hardness, abrasion, scratch and impact resistance, as well as for adhesion, slip resistance and flexibility. They also offer superior chemical resistance, and have an A+ VOC emissions rating with a low level of VOC.

Surface preparation

Bare Concrete – remove surface laitance, dust and any light dirt or grease deposits using Watco Etch & Clean. Watco Etch & Clean also etches smooth, bare concrete surfaces to provide a key. Flush with clean water and allow surface to dry. For the removal of heavier deposits of oil and grease we recommend Watco Concroff, again, flush with clean water and allow the surface to dry.

New Concrete – as a guide, new concrete should be left for eight weeks to dry (if the Application has to go ahead before this, use Watco New Concrete Primer). The surface should then be prepared using Watco Etch & Clean and thoroughly rinsed away and left to dry prior to applying this coating.

Painted surfaces – abrade to remove any weak or loose paint. Check remaining paint is well bonded. Very smooth, glossy paint should be lightly abraded to provide a key. Watco Bio D can be used to remove grease and oil from painted surfaces. Watco Concroff is a very powerful degreaser for contaminated bare concrete, do not use on a previously painted surface since it can soften paint.

Priming – is not usually required, but for open textured, or very porous high suction surfaces, such as sand and cement screed, use Watco 4 Hour Epoxy Primer to ensure a uniform finish and to prevent air entrapment bubbles. Very smooth or power floated concrete should be primed with Watco Powerfloat Primer.

Metal – remove any rust and flaking material by disc grinding or wire brushing. Apply the coating immediately after Preparation to the clean metal surface. Grease or oil can be removed using Watco Bio D. Allow the metal to dry before coating.

Galvanised Metal – Watco Galvaprime must be used to prepare galvanised metal.

Non-ferrous Metals - for advice, please contact our Technical Department.


Remove the two inner tins from the tall outer tin. Stir the contents of each tin thoroughly and pour all of the contents into the outer tin, (scrape around the inside of the tins to remove any residue). Mix the components together thoroughly using a spatula or similar wide bladed tool, (a piece of wooden batten is ideal) and do not thin. Continue mixing until an even colour and consistency are obtained. Do not mix more than one pack at a time. If a paint stirrer fitted to an electric drill is used, also use the spatula to blend in any unmixed material from the sides and bottom of the tin. In the anti slip versions the slip resistant particles are already pre-blended (in the Curing Agent).


Important - once the contents of the pack have been mixed, a chemical reaction takes place which creates heat. The product should therefore be decanted into a shallow tray to avoid reducing the pot life and used straight away. Best results are obtained in warm (minimum of 15°C), dry conditions with good ventilation. Apply one coat with a medium pile roller, (not foam), working well into the surface of the concrete. On vertical surfaces 2 thin coats are recommended. Do not exceed the maximum coverage of 18m² per 4L pack. Do not wash or allow water to lie on the surface for at least 7 days.
