Watco Heavy Duty Anti Slip Traffic Paint is a tough, two pack, anti slip, solvent based epoxy resin coating for use in heavily trafficked areas, such as car parks, driveways and vehicle access areas.

The hard aluminium oxide grit offers a good level of slip and abrasion resistance with just one high build application. This versatile, exceptionally strong coating contains a solvent which bites into asphalt surfaces, and slightly penetrates concrete surfaces for the maximum possible adhesion without the need (generally) for a primer. It contains a pre-blended aggregate which provides a finely textured slip resistant surface. It leaves a more uniform and easily cleaned finish than conventional anti slip coatings where grit is sprinkled on separately.

Heavy Duty Anti Slip Traffic Paint carries CE Mark EN 1504-2 and has impressive test results for slip resistance, hardness, abrasion, adhesion and impact resistance.

Suitable for Asphalt, tarmac, concrete, brick, masonry and similar porous surfaces. The moisture content of concrete should be less than 75% RH.
Finish Coloured, textured, low sheen.
Interior or Exterior Exterior.
Composition Two pack, solvent based epoxy resin.
Number of components 1 x curing agent and 1 x resin.
Coverage 15-20m² depending on the texture of the substrate. The coverage rate does not allow for filling the crevices and texture of a tarmac or asphalt surface. Using the product in this way will greatly reduce coverage and extend drying time.
Mix ratio 24 parts curing agent: 100 parts resin.
Application tools Medium pile roller. Cut in using a brush.
Wet film thickness 250-300 microns.
Dry film thickness 200-250 microns.
Minimum application temperature Air temperature 15°C, floor temperature 10°C.
Pot life Up to 30 minutes at 20°C.
Storage Between 15°C-25°C for at least 8 hours prior to use. Do not allow to freeze.
Shelf life 12 months in unopened container.
Principle limitations Watco Heavy Duty Anti Slip Traffic Paint is intended as a decorative finish only, and will not bind or fill weak or defective asphalt surfaces. Do not apply too thickly - this coating contains an aggregate to provide slip resistance and if applied too thickly the aggregate could settle within the paint film and slip resistance will be reduced. Similarly, if the crevices and texture of the asphalt are filled with paint, this can prevent water draining which may result in a slip hazard. Although Heavy Duty Anti Slip Traffic Paint is resistant to degradation by UV rays, after intense or prolonged exposure to sunlight, some weathering may occur such as loss of gloss or slight fading – the strength and mechanical properties will not be affected. Do not apply to damp surfaces. Wood – If a small wooden section needs painting, providing it is sound, clean and dry and is not allowed to flex, this coating would be suitable. However, it should not be used on large wooden areas or decking. Unsuitable for Mastic Asphalt.
Cleaning Mild, neutral detergent – Watco Protect is ideal.
Cleaning tools It is not practical to clean applicators and they should be discarded after use.

Surface preparation

New asphalt & tarmac – should be sound and at least 3 months old. If any residual oils remain, the surface should be washed using Watco Concroff.

Existing bare asphalt & tarmac – remove any grease or oil deposits using Watco Concroff. 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.

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 four weeks to dry in the summer and six in the winter. The surface should then be prepared using Watco Etch & Clean and thoroughly rinsed away and left to dry prior to applying this coating.

Damp surfaces – this coating can be applied to residual damp which may remain after cleaning.

Metal – remove any dust 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.

Priming – Standard: one coat is generally sufficient. On very porous or open textured surfaces, two coats may be required. The first coat will act as a ‘priming coat’ and may be diluted with up to 10% water to assist with application.

Heavy duty – priming is not usually required, but for open textured, or highly 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.

Mixing (heavy duty)

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 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. The slip resistant particles are already pre-blended (in the Resin). Tip the mixed components into a shallow paint tray – do not leave in the outer tin. This coating is not intended to be thinned, however, in some situations up to 5% of Watco Solvent TH99 may be added to assist in application.


Original: Stir the paint thoroughly and do not thin, however in very hot weather, (25°C+); up to 10% water may be added to make application easier. Apply by roller and work well into the surface. It can be applied by brush but this may result in reduced coverage. Avoid applying the paint too thickly as this encourages water to puddle on the surface and as such may become slippery. If a second coat is required, apply it as soon as the first coat is dry (generally 6 hours), and within 5 days of applying the first coat. If more than 5 days elapse, the first coat should be lightly abraded before the second coat is applied. Avoid washing the surface for 7 days.

Heavy Duty:  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 asphalt or concrete. It can be applied by brush but this may result in reduced coverage. Do not exceed the maximum coverage of 20m² per 5L pack. If a second coat is required, apply it as soon as the first coat is dry (generally 6 hours), and within 5 days of applying the first coat. If more than 5 days elapse, the first coat should be lightly abraded before the second coat is applied. Avoid washing the surface for 7 days.
