PRODUCT DESCRIPTION Coprox Masonry Waterproofing is a highly acclaimed cure to dampness, moisture and water seepage. When applied to raw porous masonry structures, Coprox Masonry Waterproofing becomes an inseparable part of the structure effectively impeding the progress of moisture in or out of the protected surface.
Coprox Masonry Waterproofing is a cementitious product. It has an extremely dense structure which will not allow the passage of water molecules. It will however, allow the passage of air enabling the structure to breathe and dry completely.
Coprox Masonry Waterproofing is unique; it can be applied to the negative side in situations where it is impossible to get to the source of the problem such as basements, wine cellars, retaining walls etc. Coprox Masonry Waterproofing can be applied directly onto damp - it is not necessary to wait until the affected area is dry before treatment commences.
Coprox Masonry Waterproofing 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.
When used as a decorative application, the same colour must be used for both the first and second coat. As with all cementitious products, Coprox Masonry Waterproofing 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.
ADVANTAGES
• Waterproof
• Can be applied to the negative side
• Damp does not need to dry before treatment commences
• Wide range of colours
• More cost effective than plaster and paint
• Ideal for ponds, pools and reservoirs
• Odourless and non-toxic
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 porous mortar, screed, concrete, cement plaster or cement washes of recognised building mix standards.
b) Good quality cement, clay or unglazed semi-face bricks.
Smooth, non-porous masonry surfaces, gypsum and swimming pool plasters are not suitable surfaces.
SURFACE PREPARATION
a) Remove surface efflorescence whilst dry using a stiff bristle scrubbing brush.
b) Thoroughly clean the surface - remove dust, dirt and any other foreign matter.
MIXING
a) Sprinkle 5 kg Coprox Masonry Waterproofing slowly into 5 litres of clean water stirring constantly with a wooden paddle or a mechanical mixing device, until smooth and free of lumps.
b) Let the solution stand for 10 - 15 minutes.
c) Use within 1 hour.
FIRST & SECOND COAT
Where Coprox Masonry Waterproofing is to serve as a decorative finish, the entire wall should be completed without interruption to avoid noticeable overlaps and patch marks. Unlike conventional paint, cutting around light fittings, cornices etc., must be done during application 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.
FIRST COAT
a) Thoroughly wet a workable section of the surface with clean water preferably using a hose pipe.
b) Stir the solution well and apply to the wet section using a fibre or whitewash brush.
c) To prevent settling, stir the solution frequently throughout the application.
d) As soon as the Coprox Masonry Waterproofing 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) Allow 6 - 8 hours after curing before proceeding with the second coat.
b) Repeat steps (a)-(d) above.
POWDERING
The structure will only absorb sufficient Coprox Masonry Waterproofing as is necessary to render it waterproof. Powdering after application may therefore occur. Simply dust or wash off the excess. Before applying paint, epoxy coatings, tiles etc., the surface must also be completely dry.
Once cured, Coprox Masonry Waterproofing is non-toxic and therefore not harmful to human, animal or plant life. The water must however, be allowed to age sufficiently or be treated chemically before use or before introducing fish or plants. Consult your local pet shop, swimming pool shop or water authority in this regard.
