iam installing pine flooring in my living room. my room is 15 by 15 iam cutting 16 ft. boards and iam going to install them on top of a 3/4 in sub floor. my question is: to keep my floor from sqeaking afterwards should i #1 lay 15lb felt paper down first then nail,or skip the felt paper and use a adhesive to the bottom of the boards and then nail.my boards are 5and 3/8 wide and iam afraid if i dont use an adhesive they wont lay on the floor tight enough,and if i put felt paper down how can i use the adhesive because the felt paper wont be completely bonded to the floor?? PLEASE HELP THANK YOU!!
