CONTINUOUSWAVE

Have a 1984 Outrage 22'. I pulled the rear deck over the live well. Deck is not soft, but the wood is starting to get wet. I don't have the time to chisel out the wood, replace it then glass it in.

Does anyone think that lining the bottom of the deck in Redgard would work?

I see this product for tile and stone applications.

If you don't have time to address it now, can you leave as is until the offseason?

There are some spots that were pretty soggy. I'm not even certain that I can get to it next winter.

Thought it would buy me some time.

I'm a tile guy and have used red guard for many purposes. I'll say this..it's basically pure latex. So it's a great waterproofing membrane between two surfaces. BUT it has absolutely no life span when exposed. It's wear life is very short in other words...You will be able to simply roll up a corner and remove the entire application area like a skin if left uncovered. This could be good if you don't plan to use the area, but bad if you plan to clean the deck or stand on the area. It's very temporary at best if used. Great protection if unmolested by you or the elements...Good luck.

one more thing! redguard will form a moisture barrier of course, locking IN moisture as well, so it will impede your drying of the area..FWIW

just noticed that you were going to apply to the underside, sorry, no wear worries, but it doesn't cure well to moist surfaces..
