We have a couple of indoor rattan chairs which we want to repurpose as outdoor furniture. They will be in a covered entryway and should be set far enough back to keep them out of direct sun and rain (other than the rare wind-driven storm). I've found articles about using polyurethane on the wood and marine waterproofing spray for the fabric (and figure I could use silicone spray on the metal springs to try to keep rust under control). But as we live in the southeast, humidity is the real issue and I was wondering about the foam padding in the cushions. Is there anything I could use on the padding to make it moisture resistant (vs. waterproof which is probably not necessary) that wouldn't destroy it? Or barring that, any reputable sources for outdoor foam padding? Thanks in advance.

 

Hello and welcome to the forum! There is silk film you can use to wrap your foam which you can get here.
You could also use painter's plastic, but the silk film is nicer. They also sell outdoor foam if you'd rather replace the foam.

 

Thanks for the response, and will check into these options.
