Surface preparation

Surfaces should not have been previously painted. They should be firm and free from loose material, mould, oil or grease. Organic growths should be removed by brushing with a solution of 1 volume household bleach (sodium hyperchloride) and 3 volumes water. Allow 12 hours to kill spores and then remove with a wire brush and flush with water. Allow the surface to dry before applying Cretestain. Extremely dense, steel or power floated floors may require acid washing prior to application of Cretestain to make them penetrable.

Mixing

Cretestain can be diluted with water if lighter shading is required. Do not dilute black.

Application

Apply with an acid-resistant paintbrush, spray canister, etc. ensuring that adjacent areas are protected from over-spray and spills. Avoid splashes, puddles and dry joints by maintaining a wet edge and applying continuously between architectural features. Using an acid-resistant brush, scrub the Cretestain into the surface once it has been applied. Vertical applications are to be started at the bottom, commencing upwards whilst avoiding excessive run-down. All reacted residue must be removed by flushing thoroughly with water after a minimum of 4 hours. Subsequent treatments may be necessary to achieve the desired depth of colour or special

effects. Newly placed concrete must be cured for at least 14 days prior to application of Cretestain.

Sealing

Once dry, surfaces should be sealed with 2 coats of Colour Hardener Sealer in accordance with its data sheet.

Coverage

Brush application - approximately 8m²/litre/coat, depending on suction and texture of surface. A sample area should be done to confirm colour and coverage

Packaging

Available in 125ml, 1 litre and 25 litre non-returnable containers.
