I have been advised by plywood sellers to buy BWP(Boiling water protection) grade plywood from kitchen to cupboard,showcase,TV stand and it's expensive as well.
But some people suggested me to use Moisture resistance grade plywood for cupboard and its cheaper than BWP but again it's expensive though
I personally feel except kitchen for any other furnitures I should just use hardwood ply and that should be enough if there's any possibility of water coming in contact either as liquid form or gas then Hardwood ply should do and it's relatively affordable as well.
FYI: From my home the coast is 25 km and average temperature is 30 degree Celsius so would it be ok for me to go ahead with Hardwood ply or I should consider Moisture resistance grade ?
