That may be true Dave but what the hell does that have to do with requiring
the painter to seal the back side of the baseboard..With the leaks NOT
spills you mention sealing the baseboard won't do diddly squat...You'll have
ALOT more to be concerned about then the back side of the baseboard being
painted...As I said the homeowner is a PITA and is full of it....But thanks
for throwing the Red Herring into the discussion...
