| Substrates
All metal laminates should be bonded to medium or high
density fiberboard, high quality particle board or plywood of sufficient
thickness. The quality of the substrate will promote better adherence
and flatness. Sheet metal and metal laminates can be bonded to flat sheet metal
substructures such as elevator doors. Do not specify drywall, gypsum, concrete, solid lumber or underlayment as substrate
for bonding sheet metal and metal laminates.
