Solid surface is a non-porous low-maintenance material used for surfaces such as countertops. It can mimic the appearance of stone, wood and other naturally occurring materials, and can be joined invisibly by a trained craftsman. Typically manufactured in sheet form for fabrication into finished countertops, solid surface can also be cast into a variety of shapes, including sinks, shower pans and bathtubs. Sheet goods can also be heated and bent into three-dimensional shapes using a process called thermoforming, which adds to the versatility of the product. Color and design flexibility are key factors when choosing engineered composites over natural stone.
In a residential setting, solid surface can be used as kitchen countertops, bathroom vanity tops, and shower and tub surrounds. Countertop fabricators typically join solid surface sheets into desired shapes using a two-part adhesive, after which the cured joint is machined flat. The same method is used to create extra thick edges, which can be machined u sing tools and techniques similar to those used to work hardwoods.
