Anybody know of a way to seal and waterproof mdf for outdoor signs?
Honestly, The best way is to choose a diffent material. Even with coats and coats of paint and urethane. The moisture will find a way in and ruin the project.
I have to agree with Seth here, MDF and outdoors just don’t belong in the same sentence in my opinion.
Yeah. That’s what I thought. Thanks.
Hello. Don’t know where you are but do a search for medite tricoya mdf. I’m in Scotland and have worked with this on a few exterior projects. Hope that helps.
Sorry P.S. It’s really expensive , £200 odd for an 8’x4’
