We wish to lay new flooring above our existing chambered edge flooring. The existing floor is nailed to a plywood sub-floor and is completely flat, about 20 years old.
This will make the whole house one even level with no raised sections across all 1st floor rooms, additions, and kitchen without the need to remove perfectly good tiling and engineered hardwood in the existing additions and kitchen.
"OK to do?" I.E. Is it acceptable to edge glue tongue and groove, non locking, engineered hardwood to make floating floor over existing varnished hardwood flooring that has chamfered edges ?
