What is the best way to remove paint from an outdoor deck?

Is the entire deck painted or has paint spilled

pressure wash first. then strape the flakes up. They have paint thinners in hardware stores, but that is a lot of work, Why not just repaint it.

It depends on what was used before. If a product called Restore by Rust Oleum was used, the best way to get it off is to use boiling water. If it's not Restore, Tammy's instructions are good except, I believe she meant paint strippers, not paint thinners to remove old paint. I'd try pressure washing then see if the rest can be sanded off. Paint removers are a pain. I'm trying to remove paint from a table top and am on the edge of quitting and throwing the table away, BUT I'm stubborn and don't want to let it beat me. Therefore I procrastinate. LOL

Entire deck I used deck restore

Hi there, I'm not sure what your deck is made from but in most cases, you can use a pressure washer to remove any loose or peeling paint, then, depending on the type of deck you can prime and repaint it with a suitable paint.

If you want the paint completely removed, you will need to use a chemical stripper. After that, it will need sanding.
