What I can use to waterproof that wooden AC tray?

I'm looking for a good suggestion. I have my air conditioner sitting in a wooden tray, but I don't want the wood to get wet and rot out.

It's currently covered by a couple layers of spar urethane, but I don't think that's enough.

Any suggestions what I can use to waterproof that wooden tray?

My normal response to any wood needing water proofing is epoxy. Maybe a layer of 4 oz. fiberglass also for abrasion. But since you already have urethane on it, I don't think that will work.

Not sure on this, but what about the stuff that you dip tool handles in to put a rubberized grip on them?? It is liquid and you could probably just poor it around in there and paint it up the sides a bit.

something like this: http://www.kk.org/cooltools/archives/000210.php

I like the looks of that clear coating from Gemplers, but I am not going to pay $107 for a gallon of the stuff!!! :o :o :o

Any other ideas?

What about making a metal tray out of some galvinized sheet with a 1" lip around the edge. You could use roofing caulk to seal the corners.

We got a clear water proofing brush on product at Menards. We used it around skylights on the roof and 5 years latter it is still clear and no leaks.

What about the stuff they use on bartops. It looks like it's about an inch thick - but it's not. That oughta do it for ya'.

PVC shower base stuff will do it and you don't have to stick it down. Just cut and cement the corners.

Mine is done with epoxy. An after thought and the epoxy stuck to the polyurethane. :roll: At least I think it did.

I see by some of the post fiber glassing the area leaves a clear finish and is water tight, but requires a lot of work and special venting considerations during the application. :thinking:

If you can get by with a rubber membrane for a pan, one is available from HD or lowes that is used under shower stall installations. its available by the foot.

Personally I'd prefer the clear approach :thumbsup:

I used epoxy and glass cloth, I don't remember what the weight was. It was to glass the fins on one of my rockets so it was pretty light weight cloth.

I guess the question is, can you epoxy over spar urethane?
