Datasheets, fabrication manuals, and warranties.
The full technical library is available on request. Specifiers can submit project details and we'll route the right datasheet bundle plus a certified fabricator contact.
Fabrication manual
Cutting, seaming, edge profiles, sink installation, color matching.
RequestWarranty terms
10-year limited transferable warranty. Scope, exclusions, claim process.
RequestSpecifications
Material properties at a glance.
Solid surface is a thermoformable acrylic-mineral composite — non-porous, repairable, and seamlessly bondable. Standard sheets ship in 6mm, 12mm, and 19mm thicknesses; wide-format and translucent variants are available on request. Listings: NSF/ANSI 51 (food zone), GreenGuard Gold (low VOC), Class A fire rating per ASTM E84.

Fabrication
Certified fabricators only.
Grand Stone is installed by a network of certified fabricators trained on seaming technique, sink bonding, edge buildup, and thermoforming. We do not sell sheet material into the open market — every project routes through a fabricator partner so installation quality is warranted end to end.
Fabricator partners receive the full installation manual, edge-profile templates, color-matched seam adhesives, and a project hotline. Specifiers working in a region without a partner can request introductions through the project enquiry form.
Care & repair
Designed to be refinished, not replaced.
- Daily cleaning: warm water, mild soap, soft cloth. Avoid abrasives on matte finishes; rinse thoroughly.
- Stain removal: most household stains lift with a non-abrasive cleaner. Persistent marks can be sanded out by a fabricator.
- Scratch repair: surface scratches are sanded and refinished in place — no replacement, no demolition.
- Heat & impact: solid surface is not heat-proof. Use trivets for hot cookware; avoid dropping heavy objects on edges.
- Cleaning agents to avoid: drain openers, paint strippers, oven cleaners, undiluted bleach for prolonged contact.
Sustainability
Durable surfaces, lower lifecycle impact.
Grand Stone surfaces are repairable through their service life, deferring the replacement cycle that drives most countertop waste. GreenGuard Gold certification limits indoor-air VOC emissions; non-porous composition eliminates the need for sealants or solvents in routine maintenance.
