Coverage & How Much You Need:

A 60 in. x 144 in. sheet covers 60 sq. ft., a 48 in. x 96 in. sheet covers 32 sq. ft., and smaller sizes proportionally less before trim. Size the job by counting countertop deck area plus edge strips and backsplash pieces.

Fit and Compatibility:

Bonds to particleboard or MDF with contact adhesive; use a Wilsonart backer sheet on the underside to balance the panel. Postforming grades need postforming equipment; Chemsurf grade should not be postformed per its intended flat-layup use.


Frequently Asked Questions (FAQ):

Q: What is included in one order?
A: One laminate sheet in the grade and sheet size you select, all in 60 Matte Finish.


Q: Which sheet size do I need for a countertop?
A: Match the sheet depth to your deck width plus front edge; 30 in. and 36 in. deep sheets suit typical counters, while 48 in. and 60 in. sheets suit islands or larger work.


Q: When should I use the Chemsurf grade?
A: Choose 390 Chemsurf HPL when the surface will see regular cleaning chemicals or lab-type exposure.


Q: Is this design available in gloss?
A: This 4811 page lists only 60 Matte Finish; a separate high gloss design 4811K exists.


Q: How do I install it?
A: Apply contact adhesive to both the substrate and the sheet back, let it tack, align carefully and roll from the center outward; trim edges with a router.


Expert Verdict — Reviewed by the SuperArbor Pro Desk

With ten sizes, buy the smallest sheet that fits your run to reduce handling and waste; a 60 x 144 sheet takes two people to move safely. Keep room for the postforming radius when selecting depth on 350 grade sheets. Use the vertical grade on cabinet ends and valances where weight and flexibility matter more than wear. Always balance a countertop panel with backer laminate to prevent bowing.

Laminate edges cut like glass; wear gloves and eye protection when cutting, routing or handling large sheets.
