I need to finish three interior oak (solid core) doors. They are Mastercraft from Menards. I was wondering if I could get a brief rundown of the appropriate steps to take. From what I understand, I should use one coat of stain and then two or more coats of polyurethane. Does that sound right? Also, does the environment in which I finish the doors matter. They are currenly in my garage (while other work is being done in the basement). The temp is around 90 degrees. Thank you very much for any help you can provide!
