  • Fastening of 1/2" Plywood to match height of old engineered hardwood for LVP

    Posted by Keith on August 12, 2021 at 10:37 pm

    Hi Joe… Tomorrow(Friday) I’m getting 11 sheets delivered of 1/2″ sanded plywood to install in a bedroom that was carpet to match the height of the old cheap engineered hardwood that I’m installing the Mannington Apex on. Here is what is looks like now:

    In one of your videos to me you mentioned to run some beads of (I think) construction glue on the underside of the plywood and then nail or staple every 4 or 5 inches.

    Currently my only nailer/stapler is this 18GA one from Harbor Freight:

    It can do only 18GA Brad Nails 5/8″ to 2″ OR it can do 18 GA Narrow Crown Staples from 5/8″ to 1.5″ long according to the specs on the air gun.

    My question is will that work? (the 18GA) And if so, would I use the Brad Nail or the Narrow Crown Staples? Also, What Length?

    If none of that will work, I will purchase another air gun that can do a different size if you recommend I do.

    Here is the plywood that is coming Friday:

    Lowes model 12227

    Thanks Joe!

    I would use 1 1/4 inch staples and construction glue. Spread a bead of the construction glue every foot of the sheet.

      Hi Joe… On those 4 x 8 sheets of 1/2″ plywood that I’m gluing and stapling to the subfloor…. Can I butt them right up against each other on all 4 sides? (Or do they need some space between them like 1/16″ or so? I’m guessing you may say it doesn’t matter if I butt together due to stapling the seams every 1 inch but I want to ask to be sure. I’m starting it Saturday morning… hopefully you’ll see this early and can reply.) ???? Thanks!

        Butt them up tight.
