We have two cedar decks. We were using Cabot's Decking stain, but not satisfied as it lasted one year. We are seniors with health issues, so I went to the paint department of a national chain. We were told to use Behr semi transparent which would last us 3 years. We cleaned the deck and power washed it. We let it dry for a few days (weather was windy during this time) It took about a week and before the summer was out the paint was wearing off and peeling in spots. Confused. We did everything according to directions. We found out that it was latex semi transparent - I was specific when purchasing the paint that we had been using Cabot's oil base. We just read in a magazine that once you use an oil base you should not use a latex. How are we going to remove all paint close to house - that isn't peeling at this time. Exactly what paint/stain should we be using for longevity? Retired, limited income and health issues (only one of us can work on project). Need direction.
