Watco Cold Set Coating is a high performance formulation that can be applied in cold conditions where conventional coatings will fail to dry.

Use in heavily trafficked unheated areas, such as workshops, warehouses, loading bays and cold stores.

Cold Set Coating is resistant to UV and weathering, making it a versatile interior and exterior coating.

This tough, glossy coating is smooth and easy to keep clean and maintain. If a slip resistance finish is required, please see instead Watco Safety Coat Cold Cure (wet PTV 47).

Cold Set Coating carries CE Mark EN1504-2 and has impressive test results for abrasion, scratch and impact resistance, as well as for adhesion and hardness.

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 the 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. 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 and check remaining paint is well bonded. 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).

Application in low temperatures – if applying in cold conditions the product should ideally be stored in a warm room at least 8 hours prior to use. 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.

Priming – is not usually required, but for open textured, or very porous high suction surfaces, such as sand and cement screed, use Watco Polyaspartic Primer to ensure a uniform finish and to prevent air entrapment bubbles. Watco Polyaspartic Primer should also be used to improve adhesion on smooth (but not powerfloated) concrete.

Metal – remove any rust or 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. Wood – must be sound, clean and dry.

Mixing

Mix between 10°C and 15°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 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 side and bottom of the tin.

Application

Apply between -10°C and 15°C.

Empty the mixed components into a paint tray and apply to the floor using a short pile roller, (not a medium pile or foam), ‘working out’ the coating into a thin paint film.

A paint brush can be used for cutting in. Do not apply the paint too thickly since this will result in reduced coverage. A feature of polyaspartic coatings is that they should be applied as a thin film. The second coat should be applied as soon as the first coat is dry (generally 6 hours at 15°C), but it must be applied within 5 days. If more than 5 days elapse, the first coat should be lightly abraded.

Limitations

Do not apply to damp surfaces.

When used outdoors, Cold Set Coating will seal the substrate and in poorly drained areas puddling could occur, potentially creating a slippery surface, in such cases use Safety Coat Cold Cure.

Do not apply if rainfall is imminent.

Do not apply to power floated surfaces.

Most self-levelling compounds cannot be painted – please ask for details.

Painting chequer paint can be a problem since coatings can wear prematurely off the ‘high spots’.
