I am licensed floor contractor in the state of California. I am installing solid oak treads in open steps in stairs 2"x12"x43", because open steps over 39" wide must be over 1 1/2" thick. But, 2" solid oak treads are not available at my local supplier; they are only available in 1" thick treads.
Can I glue two 1" treads to make one 2" tread and be within code?
If so, how would I do this?
