Decorating Instructions

Coprox Waterproof Dualcoat is an easy and effective cement based waterproofing or decorative wall and floor coating suitable for commercial and domestic applications. It is ideal for the waterproofing of water bearing positive side surfaces or interior surfaces such as bathrooms, showers and kitchens. Coprox Waterproof Dualcoat provides waterproofing and an aesthetically attractive decorative finish all in one step. It eliminates the need for plaster, paint and tiles, providing an attractive and unique naturally aged, mottled and rustic finish, which becomes more pronounced over time. It is available in a wide range of striking colours. It can be brush applied as an elegant textured finish to a variety of surfaces or can be trowelled to a classic glass smooth skim coat finish onto walls, floors and over clay tiles.


Where Coprox Waterproof Dualcoat is used as a decorative finish, it is still applied in exactly the same manner as a waterproofing application. (see Waterproofing Instructions)

For aesthetic purposes however, additional attention must be given to the surface preparation. Where unpainted and painted surfaces adjoin each other, the unpainted surfaces should first be painted the same colour as the painted surfaces before application commences in order to minimize colour variations of the completed application. When used on dry wall partitioning, the joints should first be covered with jointing tape and then the entire surface primed with a suitable oil based primer.

The application should only start once all building or renovation work has been completed, as cement coatings cannot be easily touched-up once dry without leaving noticeable patch marks.

An entire wall (corner to corner) should be completed without interruption. Cutting around window and door frames, light fittings and cornices must be done as and when they are encountered and not prior to application.

Work in manageable sections. Do not allow previous sections to dry before continuing with subsequent sections – overlap marks will be noticeable if wet and dry edges of sections overlap each other. Work section by section and complete the entire surface area without interruption.

On high walls or large surface areas, one applicator should apply from the top down while another applies from the bottom up, or one applicator applies from the left side and another from the right.

Where a Second Coat is desired, the same colour must be used for both the first and second coat. The second coat may appear lighter than the first coat.

When being used in bathrooms, showers and kitchens the application should be sealed with Coprox Wall & Floor Clear Sealer to prevent staining.
