  • As a coating in walk-in fridges, cold stores and loading bays


  • Withstands heavy wear and tear
  • Excellent chemical resistance
  • Can be applied between -10°C and +30°C

Surface preparation

All the surfaces must be -10°C or above and free from ice or water. The concrete to be treated must be at least four weeks old, completely dry and free of contaminants. Grease or oil should be removed with Watco Bio D (or a similar emulsifying degreasant) and the area thoroughly washed off and allowed to dry.

Very smooth concrete or concrete with surface laitance (a weak dusty layer) should be abraded or etched with Watco Etch & Clean to ensure adequate adhesion. The concrete should be thoroughly washed down and allowed to dry after treatment with Watco Etch & Clean.

Watco Powerfloat Primer is recommended on power floated surfaces but it must be fully cured before over-coating. Previously painted surfaces should be thoroughly abraded by sanding to improve adhesion and to remove any weak or loose material. A trial area is advisable to test compatibility with previous coatings. 

Below 5°C it may be necessary to avoid processes which involve wetting the floor due to the difficulty in drying. A good sweep or mechanical brushing may be sufficient. Do not apply outside if rainfall is imminent.


Only mix in temperatures between 10°C and 25°C. Remove the two inner tins from the tall outer tin. Stir 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 a similar wide bladed tool (a piece of wooden batten is ideal). 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. Do not dilute.


If appearance is critical we recommend the application of a small trial area first.

Only apply in temperatures between -10°C and +30°C. The viscosity will be somewhat thicker at very low temperatures, slightly reducing coverage.

Useful information

Our Cold Set Coating needs to be applied in two coats. It’s supplied as a tin of resin and a tin of curing agent. And when you mix the contents of the two tins together, it starts a reaction which causes the paint to cure.

If you’re painting an area of 30m², you’ll need four 2.5L tins (because, once mixed, a tin won't keep for the second coat).

Here’s how we work it out:

  • Area to be painted: 30m² with two coats (we recommend two coats for the best result)
  • Tins needed: 4 x 2.5L
  • Why: Use 2 x 2.5L for the first coat; and the same again for the second

Our Coverage Calculator works this out for you – that way you know you’re buying exactly the paint you need and can use, without unnecessary waste.
