I built a bunch of small wooden planter boxes out of plywood. They will be for indoor use only and I am looking for an easy way to waterproof/seal the inside of them. I’m thinking some kind of a spray? I’ve also considered epoxy but that’s a bit on the expensive side and can be messy. Looking for a cheaper, easier option. Thanks! via /r/DIY https://ift.tt/2Mr3KKq
