Grades

Solid surface types shops run most

Solid surface is specified by resin type and thickness. These are the choices you will make when you order.

Acrylic solid surface

The premium type (Corian-style): fully thermoformable into tight curves, seamless, and repairable. The default for high-end counters and sinks.

Best for Countertops, integrated sinks, curved cladding

Polyester solid surface

A lower-cost resin with brighter color options and good hardness, but more brittle and less thermoformable than acrylic.

Best for Budget counters, vertical surfaces, color-critical work

Acrylic-polyester blend

A blend that balances cost against thermoformability and durability, common in mid-range product lines.

Best for General countertop and surfacing work

6 mm vs 12 mm sheet

Thin 6 mm sheet is used for cladding and vertical surfaces and built up at edges; 12 mm is the standard for horizontal countertops.

Best for 6 mm: walls and cladding. 12 mm: countertops

Specs

Material properties

Representative values for acrylic solid surface. Exact numbers vary by brand and resin.

PropertyTypical value
Density~1.7 g/cm³
PorosityNon-porous; no sealing needed, hygienic
Max service temp~90 °C (195 °F); use trivets for hot pots
ThermoformabilityAcrylic grades bend into curves when heated
RepairabilityScratches and burns sand out; renewable surface
SeamingChemically bonded into inconspicuous seamless joints
MachinabilityExcellent; routes and cuts with woodworking tooling
Stain resistanceHigh; non-porous surface resists most staining

Solid surface is renewable and seamless, its two signature advantages over stone: scratches sand out and joints disappear.

Forms we machine it from

Sheet & slab

Routed, cut, and seamed into counters, sinks, and cladding.

Finishing

Finishes for solid surface

Solid surface finish is a surface texture, not a coating, and it can be changed after fabrication.

Matte / satin

The standard hygienic finish; hides scratches and is easy to maintain and renew.

Semi-gloss

A brighter surface for a more polished look, which shows wear sooner and is renewable by sanding.

High gloss

A polished finish for feature surfaces; higher maintenance and best on vertical or low-traffic areas.

Seamless bonding

Sheets and edge build-ups are chemically bonded and sanded flush into inconspicuous seams.

The finish level can be adjusted on site by sanding, and burns or scratches are repaired the same way. Call out the finish and edge profile on your drawing.

Applications

Where solid surface parts are used

Solid surface is used wherever a seamless, hygienic, repairable surface matters.

Architecture & construction
Commercial interiors
HealthcareHospitality
Retail fixtures
Residential kitchens & baths

Compare

Solid Surface vs other materials

How solid surface compares to the stone surfaces fabricators quote.

Solid Surface vs Quartz

Quartz →
  • Quartz is far harder, more scratch- and heat-resistant, and needs no renewing
  • Solid surface is seamless, thermoformable, warmer to the touch, and repairable by sanding
  • Quartz seams are visible; solid surface joins are invisible

Choose solid surface for seamless, curved, repairable surfaces and integrated sinks. Choose quartz for maximum hardness and heat resistance.

Solid Surface vs Granite

Granite →
  • Granite is a natural stone: harder, heat-resistant, and unique in pattern, but porous and needing sealing
  • Solid surface is non-porous, seamless, and consistent in color, and never needs sealing
  • Granite has visible seams and cannot be thermoformed or sanded to renew

Choose solid surface for seamless, hygienic, consistent surfaces. Choose granite for natural stone character and heat resistance.

Questions

Frequently asked questions

Solid surface is a composite of acrylic or polyester resin filled with mineral (usually alumina trihydrate) and pigment, cast into sheets. Corian is the best-known brand. It is non-porous all the way through, so it can be sanded, seamed invisibly, and thermoformed, unlike stone or laminate.
