Due to the variable nature of concrete surfaces some concrete may not be suitable for painting (e.g. underbound, smooth trowelled or glossy concrete). All bare concrete should be tested for suitability prior to application of Berger Jet Dry. A simple water bead test will determine if the surface is sufficiently porous to allow adequate penetration of the product. This is indicated when water drops absorb into the surface, instead of beading on the surface. If beading occurs the concrete will require either abrasive blasting or acid etching. To acid etch, mix 1 part of Spirit of Salts (hydrochloric acid) to 3 parts water. Apply liberally to the concrete and begin scrubbing with a stiff broom. Care must be taken - Avoid contact with eyes and skin. Wear goggles, gloves and cover all areas of the skin. If contact is made with the skin, wash immediately with water. Allow 15 minutes for the acid mix to react on concrete surface before rinsing off with high pressure water hose – it is important all the acid is completely removed from the surface. Repeat treatment as necessary, until the surface is clean and has a rough feel (like sandpaper). This will vary depending on the concrete. Allow to dry thoroughly before painting.

Previously painted surfaces: Ensure previously painted surface is sound by cutting a small X through the existing paint with a sharp blade, press cellulose tape firmly across the cut, then rip off the tape. Repeat at random in a number of areas to test the surface. If the old paint comes off, it is unsound and should be completely removed. All sound gloss and semi gloss paint surfaces need to be sanded to a matt finish and thoroughly cleaned in order to provide good adhesion. Then apply 2 coats of Berger Jet Dry Non Slip. All surfaces where the paint has been removed must be thoroughly cleaned and treated as per instructions for bare concrete.

New Concrete: New concrete surfaces must be allowed to cure for at least 12 weeks before etching and painting. Longer curing times may be required depending on environmental conditions and the thickness of the concrete.

Aged, unpainted or worn concrete: Remove poorly bound or powdery concrete with a wire brush before etching and painting.

Stained concrete: Lightly stained areas (car oil, grease etc) should be cleaned using commercial concrete cleaners.

Brush, roller, conventional or airless spray.
Stir thoroughly with broad flat paddle before use.

Apply 2 coats by brush or roller using full even coats direct from container. It is recommended to thin the first coat of Berger Jet Dry non Slip with up to 10% by volume of Mineral Turpentine to aid penetration. Suitable for application by standard spray equipment. If necessary thin with mineral turpentine or enamel thinner to aid atomisation up to 50ml per litre.

Allow a minimum 24 hours drying time after application of final coat before subjecting the painted surface to normal pedestrian traffic. Under cooler or humid conditions be sure to allow longer drying times.
