Concrete Etcher

Concrete_etch_1kg

White Knight Concrete Etcher is a preparational product, which roughens the surface of smooth concrete and increases the ability of paint to bond to it. It is non-toxic, environmentally friendly, low in odour and doesn’t generate aggressive fumes. A powder form additive, it is very easy to use: just add to water.

Smooth concrete must be etched before painting to ensure maximum adhesion.

Application Details

Application Details

Use a plastic watering can to evenly pour the solution over the concrete and then scrub with a stiff bristle broom. Reaction of  White Knight Concrete Etcher with the concrete is shown by bubbling or foaming. Allow the Concrete Etcher solution to react with the concrete for 20 seconds or after bubbling stops. If the etcher solution does not foam a clear coating or surface contamination may be present. The clear coating must be removed by mechanical means before etching. 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. 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.
