Coverage & How Much You Need:

One sheet covers up to 60 in. x 144 in. (60 sq ft) in the largest size, or 30 sq ft in a 30 in. x 96 in. sheet. Size your job by laying out parts within the sheet dimensions and allowing for trim and seam placement.

Fit and Compatibility:

This design bonds to particleboard, MDF or plywood substrates with contact adhesive, and pairs with matching Wilsonart edge treatments and backer sheets. Compact grades are self-supporting and do not require a substrate; all other grades require bonding to a stable core.

Expert Verdict — Reviewed by the SuperArbor Pro Desk

For countertops with a rolled front edge, pick the 350 Postform grade in 60 in. x 144 in. so the nose is formed, not seamed. Always bond to a balanced substrate and add a laminate backer sheet to the underside to prevent warp. If the job calls for a self-supporting divider or worktop, the 1/2 in. compact items avoid the substrate entirely. Where aggressive cleaners are expected, step up to the 390 Chemsurf grade.

Laminate sheets have sharp edges after cutting and require contact adhesive with proper ventilation, so wear cut-resistant gloves, eye protection and follow the adhesive manufacturer's safety instructions.
