I have just finished building a deck made out of pressure treated lumber. Should I be putting a sealer on it or can that wait for a while. Does it need a sealer at all? I also have a pressure treated fence which is 2 years old and the wood is starting to turn grey. I know you don't advise putting a stain on but would a seal or wash keep it looking good?
Answer:
The PT products don't need anything in the way of preservative and colour is something you can adjust. To keep it looking good, you might want to wash is with a biodegradable wood wash every couple of years and when the PT colour starts to fade you can stain it.
