Expert Verdict — Reviewed by the SuperArbor Pro Desk
For a typical countertop with a rolled edge, spec 350 Postform HPL in 60 in. width over particleboard; for cabinet ends and wainscot, 335 Vertical HPL saves weight and cost. Choose the 604 fire-rated vertical grade only where the project documents call for a fire-rated laminate, and keep finish selection in mind because gloss finishes show more handling. Acclimate sheets flat in the room before bonding to avoid warp.
Handle large laminate sheets with two people and wear gloves and eye protection when cutting, as edges are sharp and dust is a irritant.
