No, not a fully cured one. KBS Klean is used all the time to clean painted surfaces and will not harm a fully cured coating when used according to the directions. Two conditions do the work in that sentence: the finish has to be fully cured, and you have to follow the directions, which means diluting it, not letting it dry on the paint, and rinsing thoroughly.
Cured Is the Condition
A fully cured coating has developed its final hardness and chemical resistance. A film that is still curing has not, and that is true of any coating, not just KBS products. If the paint is new, let it cure completely before you clean it with anything.
For reference, RustSeal cures by absorbing moisture from the air and forms a rock hard, non porous shell; the RustSeal directions carry the recoat and cure figures for that product.
How to Clean Painted Surfaces
- Start at the lightly soiled ratio of 10 parts hot water to 1 part KBS Klean and step up only if the dirt does not move.
- Shake well, apply liberally, and wash for 5 to 10 minutes or as long as needed.
- Use a soft applicator on finished surfaces. Save the bristle brush and scouring pad for heavily soiled bare metal.
- Do not allow KBS Klean to dry before rinsing.
- Rinse thoroughly with water and let the surface dry.
Test an inconspicuous area first on any finish you have not cleaned with it before. That is ordinary practice with any cleaner and it costs you two minutes.
Where This Comes Up Most
Chassis work, mostly. You are treating bare and rusted areas of a frame that also carries sound cured paint or undercoating, and you want to know whether the cleaning step will cost you the good coating next to the bad. It will not. Neither will the etch step: RustBlast will not disturb a fully cured coating either.
