Hi everyone. Now I've just finished building my new pallet decking. Now it looks amazing and very proud of our hard work but I have been told a couple of times that the pallets I used may rot! The decking has membrane sheeting underneath and also it is on slabs off the floor... I would love some info or advice on how to keep it in great condition. Thanks in advance.

Welcome Alfie1000. That looks great. Pallets are usually made from cheaper and untreated wood so you will need to paint or stain it like any deck. They are often in full sun and/or close to ground level and need more attention.

A good stain with sealer built in, paint or one of those deck restorers like Deck Over.

Looks great but I think you should have used treated 4x4 lumber. As Marc said pallets are usually made from cheap untreated wood. Hopefully being raised off the ground with the stone will keep them around for awhile. I agree about getting some water sealer on the deck.

Nothing you can really do now. The rotting will occur between the ground area and the underside, where it will hold moisture. The wood should have been painted with water sealer before it was built/assembled. Hopefully it will last a few years before you need to redo it and it didn't cost much.
