Our Gaco deck- What can be done to seal it & cover seams?
We had our wood deck painted with Gaco finishled by ProfessionalS. The seams twisted the first summer & a few holes appeared. The professionals sanded the seams & repainted with Gaco with the sand finish. We can still see the tape lines & they are twisting again. I know about heat making things expand & cold contracting but this is outdoor paint. What can be done to seal it & cover all the seams?
