Principle limitations Can be applied to asphalt where vehicles will be parked, but not recommended for concrete where vehicles will be parked, (see instead Watco Heavy Duty Anti Slip Traffic Paint, a strong, two pack, anti slip, solvent based epoxy resin). Watco Asphalt Paint is intended as a decorative finish only, and will not bind or fill weak or defective asphalt surfaces. Do not apply in areas which will be constantly under water. Please refer to Watco Anti Slip Traffic Paint where slip resistance is required. Do not apply too thickly. If the crevices and texture of the asphalt are filled with paint, this can prevent water draining which may result in a slip hazard. Do not apply to Mastic Asphalt.
Cleaning Mild, neutral detergent – Watco Protect is ideal.
Cleaning tools Water.

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, but not where there is rising damp.

Priming – 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.


The paint should be thoroughly stirred and should not be thinned, 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.
