Wood over cinderblock wall outdoors
I am very new at this and am trying to add a decorative element to my backyard. i have a cinder block wall, and my landscape guy tried attaching douglas fir 1x10x10. With two days of rain, they warped, split, and look awful. I have realized he doesn't know what he is doing and I am have to figure this out myself. Any suggestions of the right wood to use? He also was installing with nails, and not using cement glue.
I rally appreciate any suggestions and help.
