FAQ - Preparation

I've applied the paint over existing solvent based paint that was in good condition but the paint chips off when knocked, why is the happening?

When using this type of paint it is essential the surface to be painted is clean and dry. However rubbing down to provide a key is just as important especially when painting over old gloss finishes. Failure to carryout any of these two simple processes will result in a lack of adhesion making the coatings much more susceptible to impact.
