Underlayment subfloor

Post by Sprague22 » Wed Oct 02, 2019 4:39 pm

So i have an older home built in 1971. I am remodeling and i ripped up all my old hardwood floors and found my subfloor to be 1/2 in plywood. I screwed the subfloor down where the existing nails were to fix the squeaking.

I plan to install LVP pergo outlast floor so i need to strengthen the subfloor as it is not going be 3/4 thick like traditional hardwood. I play to lay underlayment plywood ontop of the subfloor and screw it down. My question is should i install the plywood in the same direction as the existing subfloor or in the oposite direction. Also is screwing the plywood to the subfloor fine or should i glue and screw. Thank you

I would keep the new layer running the same direction but stagger the joints and seams so they are not in the same place as the original. I would off set them at least 16".
Screwing the new layer is completely fine on its own, glueing it down will create a huge job for the next guy years down the road.
