What is the best way to do subject when the seams of the panelling are not smooth. Should I use a drywall filler to smooth out the gaps?
Answer:
Even drywall filler will shrink back as it re-acts to temperature and atmospheric humidity. The long and the short of it is that if you have grooved panelling, wash it with steel wool and varsol and then prime and paint it because if you paper it, the grooves will show through.
