    Plywood floor
    Two parts

    1. Having ripped up the kitchen floor tiles in my 1989 townhouse, the half inch expansion gap is on three walls only? The wall with the window has no gap? As I am fitting new plywood after taking up old plywood floor, should the window wall have a gap also?

    2. The current plywood floor is 1/2" thick, the solid wood strips I am laying require 3/4" plywood for the nails. Underneath the current plywood is another floor? I have no idea how thick although I can drill a hole to measure depth? Will I need 3/4 ply for the new floor, or will the second floor + new 1/2" plywood suffice?

    Welcome to AMHD

    1. When plywood is nailed and glued, movement will be limited if nonexisting. Would leave about 1/4'' on all walls.

    2. The one layer of 1/2'' u are putting down will be enough.

    As I am fitting the plywood floor into my own kitchen, I want the best plywood for the new hardwood strips. Is it worth fitting plywood that is normally used in the kitchen units/cupboards itself? This plywood is much smoother. Also is pine plywood fine or will oak or other plywood be better?

    Best wood type for plywood floor?
    I will be laying plywood underfloor before nailing down hardwood strips. Pine seems easily avaiable, is oak or other wood better for 8' x 4' underfloor sheeting? Also is it worth laying smooth plywood that is normally used for kitchen units/cupboards?

    AC plywood is plywood with one side that has the knot holes filled so that u have a smooth surface.

    One side good is plywood with no knot holes and has a smooth surface.
