I have recently re-fitted our kitchen. We choose the paint from the kitchen catalogue as it matched the kitchen units. Not very original I know but anyway. The paint was described on the tin as a chalky elmusion. The colour is fine but the paint finish marks so easily. We have a dog and kids and it is scratched and marked within weeks. Is there product I can paint over it to protect it and make it easier to clean and less prone to scratches? Would a thinned PVA solution work?
