Please select from the below:

Waterproofing Decorating Changing Existing Colour

Suitable Surfaces

Sufficiently aged and cured, porous virgin mortar, screed and plaster of recognized building mix standards.
Good quality virgin porous cement and clay bricks.

Weather Conditions

Do not apply to exterior surfaces if rain is imminent, during high winds or freezing temperatures.

Surface Preparation

Remove any efflorescence whilst dry using a stiff bristle scrubbing brush.
Clean the surface – remove dust, dirt and all other foreign matter.

Mixing

Pour 5 litres of clean water into a clean plastic container.
Sprinkle 5 kg Coprox Masonry Waterproofing slowly into the clean water stirring constantly until smooth and free of lumps.
Use immediately.
To prevent settling, stir frequently throughout the application.

First Coat

Thoroughly wet the surface with clean water. Surfaces which are already wet as a result of damp or rain, do not need to dry before application commences.
Liberally apply the Coprox Masonry Waterproofing to the wet surface using a suitable brush. Ensure all depressions, fine cracks and pin holes are covered.
Once the Coprox Masonry Waterproofing visibly begins to dry, cure the application by evenly wetting it with a fine mist spray. Repeat this procedure one or more times to minimize crazing and powdering. In hot climates or high temperatures, cure the application more frequently.

Second Coat

Apply the second coat 6 – 8 hours or more after curing the first coat.
Wet the first coat with water and apply in the same manner as before.

Powdering

The structure will only absorb sufficient Coprox Masonry Waterproofing as is necessary to render it waterproof. Powdering after curing may therefore occur. Simply dust or wash off the excess.

Coverage per 2 Coats

2,6 m² per kg (approx.)

Filling Swimming Pools, Ponds, Reservoirs & Water Features

Remove any excess powder:

1. Thoroughly hose down the surfaces several times with generous amounts of water, 24 hours or more after the second coat has been cured.
2. Mop up the water.
3. Fill with clean water.

Toxicity

Once cured, Coprox Masonry Waterproofing is non-toxic and therefore not harmful to human, animal or plant life.

The water must be free of any excess powder and allowed to age sufficiently and treated chemically before introducing fish or plants. Consult your local pet shop or water authority in this regard.

In the case of swimming pools, pH levels should be properly maintained. All chemicals should be added via the weir.

Cleaning Tools & Equipment

Use clean water. Product and waste water containing product should not be discharged directly into drains and waterways.
