Q: What is this grade intended for?

Q: How is it installed?
A: Cut to size, apply contact adhesive to both the sheet and a flat particleboard or MDF core, wait for tack, then press and roll the sheet fully.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
River Gemstone's reddened-brown aggregate pattern is a dependable mid-tone choice that bridges warm cabinets and grey or stainless accents, and the Mirage finish resists the look of fingerprints and smudges. Use postform grade with a proper postforming setup for rolled edges, and keep a balancing backer on every top. The busy aggregate scale is forgiving at seams, making it a good pick for longer L-shaped runs. Order the 60 in.-wide sheets for island tops to avoid a seam down the middle.
Cut laminate edges are sharp and contact adhesive vapors are flammable; wear gloves and eye protection and provide adequate ventilation.
