    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: https://photos.app.goo.gl/hUcfeHBTbgSQTEvbA

    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: https://photos.app.goo.gl/suuTKcDdChFwPk7d9

    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: https://www.lowes.com/pd/Plytanium-15-32-CAT-PS1-09-Square-Structural-Plywood-Pine-Application-as-4-x-8/3010108

    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.
