Had my kitchen and master bath redone in January. Extra backer board, also called cement board was left in my carport. Since then it has snowed & rained a few times. Some if it has gotten wet and dried.

I was wondering if it was anygood after being left out in the weather like that. It is under the carport, but sometimes the snow or rain will come down sideways and still get stuff in there wet.

Anyone know, or have an opinion; should I trash it or hold on to it, about 3 or 4 extra panels of the stuff.

 

How does the stuff look? Is it warped at all?

Considering that backer board is made specifically to go behind tile in wet installations, I would expect it to be okay. However, if it looks messed up, then toss it.

 

for the 60 bucks you might save I'd probably toss it, or hack off the parts I thought were bad and save what I thought was good for random patch panels etc.

 

like above, it's always good to save some - you never know when you'll need it.

 

thanks.
