PRODUCT DESCRIPTION
Coprox Waterproof Dualcoat is a decorative waterproof cement wall and floor coating.

As a brush-on application, Coprox Waterproof Dualcoat gives interior and exterior walls an aesthetically appealing textured coating. A trowel-on application is an ideal decorative and durable wall and floor coating.

As a brush-on application it can even be applied directly over most surfaces without the need of a keying agent. Coprox Waterproof Dualcoat is available in a wide range of attractive colours. It achieves a unique naturally aged, mottled and rustic appearance which becomes more pronounced over time.

Where a two coat application is required, the same colour must be used for both the first and second coat. As with all cementitious products, Coprox Waterproof Dualcoat cannot be easily touched up without leaving noticeable patch marks. The application should therefore, only be undertaken once all building or renovation work has been fully completed.

WEATHER CONDITIONS 
Do not apply on exterior surfaces if rain is imminent, during freezing temperatures or high winds. Where possible apply under shady conditions.
SUITABLE SURFACES
a) Raw, cured, settled and dry mortar, screed, concrete, cement plaster or cement washes of recognised building mix standards.
b) Good quality cement, clay or unglazed semi-face bricks.
c) Dry wall partitioning.
d) Other surfaces should first be tested for suitability.
e) All surfaces must be firm, rigid and non-flexible.
SURFACE PREPARATION
a) Remove surface efflorescence whilst dry using a stiff bristle scrubbing brush.
b) Prevent or remedy rising damp or any ingress of negative moisture with Coprox Masonry Waterproofing.
c) Painted and unpainted surfaces should be uniform in appearance. All unpainted surfaces should therefore, be painted the same colour.
d) Polyurethane or high gloss finishes should be sanded.
e) Dry wall partitioning should be suitably primed.
f) Thoroughly clean the surface - remove dust, dirt and any other foreign matter.
BRUSH-ON APPLICATION
MIXING
a) Slowly sprinkle 25 kg Coprox Waterproof Dualcoat into 10 litres of clean water stirring constantly with a wooden paddle or preferably a mechanical mixing device, until smooth and free of lumps.
b) Use within 1 hour.

FIRST COAT

a) Masonry surfaces - thoroughly wet a workable section with clean water preferably using a hose pipe.
  Painted or other surfaces must be completely dry.
b) Stir the mixture well.
c) Apply using a suitable brush. The type of brush used will determine the texture of the application.
d) To avoid noticeable overlaps and patch marks, the entire section must be completed without interruption. Cutting around light fittings, cornices etc., must be done as and when they are encountered.
  On high walls, it is recommended that one applicator applies from the top down while another applies from the bottom up, continually working to a wet edge.
e) To prevent settling, stir the mixture frequently throughout the application.
f) As soon as the Coprox Waterproof Dualcoat visibly begins to dry, cure the application by evenly wetting it with a fine mist spray. Repeat this procedure at least two or three times. In hot climates or where direct sunshine cannot be avoided, cure the application frequently.
SECOND COAT
A second coat may be applied in the same manner as above. Allow 6 - 8 hours after curing before proceeding with the second coat. The second coat may appear lighter than the first coat.
COVERAGE - ONE COAT
Raw Brick - 20 m2 per 25kg (approx.)
Raw Plaster - 30 m2 per 25kg (approx.)
Painted Surface - 35 m2 per 25kg (approx.)

TROWEL-ON APPLICATION

MIXING
a) Slowly sprinkle 25 kg Coprox Waterproof Dualcoat into 7 litres of clean water stirring constantly with a wooden paddle or preferably a mechanical mixing device, until smooth and free of lumps.
b) Use within 1 hour.

APPLICATION

a) Porous masonry surfaces must be keyed using clean water. Smooth or dense masonry surfaces must be keyed using Coprox Flexible Waterproofing liquid.
b) While the surface is still wet or the Coprox Flexible Waterproofing liquid is still tacky, evenly spread the Coprox Waterproof Dualcoat over the entire surface.
c) Before the application is dry, float the Coprox Waterproof Dualcoat using a wet wooden float to a thickness of between 3mm and 5mm.
d) The entire section must be completed without interruption to avoid noticeable overlaps.
e) To achieve a smooth surface, use a wet steel plastering trowel.
f) On large floor areas, use expansion joints to minimise crazing or cracking.
g) As soon as the Coprox Waterproof Dualcoat visibly begins to dry, cure the application by evenly wetting it with a fine mist spray. Repeat this procedure at least two or three times. In hot climates or where direct sunshine cannot be avoided, cure the application frequently.
h) After curing, allow the application to dry for at least 24 hours. Drying times may be longer in cold or wet weather.
