"Sultan And Sons Plywood" offering Marine Grade Fevicol.
Whenever you use waterproof Plywood, you need to use Waterproof Adhesive also otherwise the laminate starts de-bonding after some time.
Waterproof Ply or Adhesive, both are not only waterproof and stronger than standard Ply or adhesive but costlier too.
So people restrict it to only to water prone areas
But Fevicol Marine is more than just a waterproof adhesive !!!
