Last fall I used a stain/seal for 1st on deck. Part of boards peeled.

It only happened on exposed boards n just a few of them did it. I know I need to sand them n redo but not sure why this happened.

    you put the stain on too thick so it peeled. Sand and restrain.

    Parts of the deck boards could have had some dirt embedded in them or the boards weren't completely dry.

    Same thing happened us I was told it was pine sap, because the boards were new and had not aged

    More Likely the product you used was faulty.

    Did you use a primer? In our paint store they fancy a layer of primer before painting wood.

      Is it a two-in-one product? Sometimes wood leaks out essential oils and other substances or maybe it was contaminated with something like fatty substance before. I think I would return to the place where I bought it and ask there what to do.

    If it is treated boards , which I'm assuming it is. Then your not supposed to paint or stain them for a whole years, because they have to go through the curing process during that time by drying out some . If you do paint or stain them before they are completely dry then the stain or paint will peel and flake off, because of all the excess stuff on the boards that they treat the boards with from the plant and the excess sap and moisture that is still in the boards , the paint or stain will not adhere to the boards. Besure to use a scraper and scrape off some of the sap that builds up in the middle of the board if it has any ,so you won't have a lump in the middle of the board, just an idea. I hope it helps , yaw have a blessed day.

    Moisture trapped by stain, and the sun exposure forcing it out caused the pealing. The unexposed likely cured slower so it didn't cause as much visual damage. The undamaged areas still should be moderately scrapped and sanded to make sure it is actually still adhering.

    So basically scrap and sand them down. You shouldn't have to go to bare wood, just remove the worse and really scuff and flatten down the rest. Start next time with a lighter clear or transparent stain and use sparingly, only stain after a decent dry spell, and it should over time achieve much better results.

    I used the below product on my deck and I live in Miami, tons of sun and rain and a year later it has held up.

    Hi Terrie, I'm from Canada and our winters can be brutal on decks - especially with shovelling. I suggest you Powerwash your deck and allow it to dry completely then, check your long range weather forecast. Whatever product you use requires a specific drying time - sometimes that's 2 or 3 consecutive days of sunshine to properly cure. If not, there will be peeling. Best of luck!

    Is stain and sealer combo a two-in-one product? If the wood is too fresh or maybe too old with residues of former treatments or some kind of invisible impurification, this could "come up" when being painted over. This is why the paint stores here would recommend a primer. But with a combined paint, I've no experience. I would turn to the people who sold the paint to you and ask them (equipped with the photo).
