Laying new 150x21 redwood t&g flooring in a room which had a (small) woodworm problem.
All the old infected wood/joists have gone and all new and original joists liberally sprayed twice with Cuprinol 5 Star complete wood treatment.
I've insulated between the joists with 50mm Recticle and a membrane is going under the new planks.
The new boards are going to be painted.
Question is: Should I spray the underside with the wood treatment? or is that totally unnecessary?
Thanks in advance
