SMOOTH or STEEL FLOATED CONCRETE (new or old, unpainted): This surface must be etched before painting to ensure maximum adhesion. The etching process will slightly roughen the surface by removing the sheen. The roughened surface should look like sand paper and must be present prior to painting. Etching the surface with White Knight Concrete Etcher is a safer, environmentally friendly alternative to conventional acid etching. Follow the instructions on White Knight Paints Concrete Etcher pack. After etching, it is essential to remove all loose residues before painting. This can be done by thorough scrubbing with a stiff bristle broom or by water blasting. Any scrubbing must be followed by thorough rinsing with a strong water jet from a garden hose, before the surface dries. Ensure the etching has slightly roughened the surface and created porosity. It should feel like rough sandpaper”if not, repeat the etching process. When dry test for loose residue with adhesive tape. If cement or loose material is picked up on the tape, repeat the cleaning process. If loose residues persist, call White Knight Customer Service on 131 686 for further Technical advice.

Painted Concrete Surfaces: Check for lifting of old paint prior to re-painting. If it™s not sound, the total removal of the old paint is required. Scrape off all loose and flaking paint. Remove all contaminants such as dirt, grease, oil or dust. Sand glossy or smooth surfaces to improve adhesion. Clean thoroughly with a strong detergent and rinse thoroughly with water, then allow to dry. Grease or oil spots may need a degreasing agent to remove them prior to painting. Before repainting, create a test area to ensure compatibility with the old coating. After 24 hours of drying, check for lifting of old paint or poor adhesion. If problems are observed total removal of the old paint is required. To improve Slip resistance If additional slip resistance is required add White Knight Pave and Deck Grip to the paint before application. Follow the instructions on the pack.
