Subfloor Adhesive

hey folks....

i'm prepping to install my 3/4" ply subfloor.

i've got two questions:

1) what would be the recommend screw type / length?
2) is there any subfloor adhesive that you guys have found to be best?

as always,
thanks much!

Screws - 3" square drive or combo-drive deck screws. Be careful to avoid twisting off the screw heads.

Construction adhesive - Liquid Nails in the 29 oz. size. It's about the only thing that comes in that size tube. Everything else is the 11 oz. size, such as caulk.

Here's one Howto site:

just do a Google search for "install subfloor".

You will probably have other questions as well.

I only use PL Premium Construction Adhesive by OSI Sealant. Available at Home Depot in either small or large tubes. Urethanes stick to everything. Costs a little more bu you use less so ends up the same. Strongest stuff out there.

http://www.stickwithpl.com/Products/...PLProductID=14

I have had trouble with non-urethanes sticking - like Liquid Nails or similar.

Urethane-based. Gives off no fumes. Securely bonds and is compatible with all building materials. Bonds can be made in temperatures ranging from 0 to 400 F. Material may be repositioned up to 1 hour without losing strength. Tested 3 times stronger than conventional adhesives and provides twice as much coverage as conventional adhesives. May be used inside or outside. 10 to 12 hour cure time. Exceeds glued subfloor and construction code AFGl-01.

You won't be back to Liquid Nails (or equivalent) if you try this stuff.
