building a pergola
Good afternoon folks. I am building a pergola. I would like to reduce expense as much as possible. I was planning to use pressure treated woods that we can buy from Home Depot. However, I just learned today that PTW twist. I also learned that I should buy kiln dried PTW.
My posts will be standing on an 8" diameter concrete.
What should I really buy? I don't want them to twist. Oh, is there a product we can apply to prevent this from happening or slow it down?
