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.

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.

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 – for previously painted surfaces, check compatibility with the existing coating; if compatible, 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 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.

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.

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.


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.


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.

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.
