Hi All,
Longtime reader of this forum and first time poster.
Im renovating an old california bungalow and due to variances in in existing floor levels and finishes i need to bring the floor levles up approx 20mm in some rooms.
Iam planning on doing this by sheeting over the existing floorboards with 19mm plywood.
Just a couple of questions:
1. Am i better to screw fix or nail fix and does this need to be through the boards to the joists?
2. Do i need to run the plywood at 90 degrees to the floorboards?
3. Do i need to provide glue between the two as well.
Any advice is much appreciated.
