Q: I was told my new “lap & gap” red pine may cause problems with curving, lifting, and not being able to lay down evenly. Do you have any insight on the practicality of using “lap & gap” red pine for flooring and installing “lap & gap”?
A: I am not familiar with lap and gap joints. However, I don’t see why these boards would curve after 100 years of seasoning. I think I would use a combination of adhesive and perhaps screws through the face, into the floor joists to install it. It will have to be professionally sanded and finished, but I don’t think you necessarily wasted your money. Depends the look you are after.
