Our poor poor deck was painted with brown paint, well it is peeling off bad. I am planning on pressure washing it (2400 psi-I think) to get the most of the paint off. Some of the boards have rough spots on them, can I just put on thicker stain to smooth out those spots. If the pressure washer does not work-any suggestions. I have lots of babies(four legged ones) and prefer not to use chemicals. Would a TSP solution work? any recommendations with stain?
