we have a very large commercial building that has pine log siding..the finish is peeling in some spots and the yellowy color is not attractive. what is the best way to remove all the finish? can the siding then be left unfinished to grey naturally?
Corn cob blasting would be the best way to remove it, and yes, you could leave it to turn gray. If so, you may want to apply a good borate treatment. Call Mike at 866-670-3020 for help.
