I applied solid deck stain on my deck that I cleaned well and let dry. It had not been stained previously. Some wood was new, other old, cedar.
Within two months it was peeling off (not oil based). I sent a sample to the company and they said I should have used a primer. The can did not mention a primer, instead it mentioned its superb bonding properties.
Is it common to use a primer? It’s not mentioned often in the preparation parts of “How to”.
