People use them for walls of houses. I actually have 1/4th marine ply behind them.really? how do they weather? I love the looks of them
My expectation is that they will be good for 4-5 years. With polyurethane they may be OK for 10 years.
At 40 dollars a gallon to polyurethane them, its cheaper to replace them than try and preserve them.
Lots of resorts use them to give a native feel and the patterns in the weave can be quite beautiful.
I just went for the basic basic.
