What is solid surface?
Solid surface is a cast sheet material made of acrylic resin (PMMA) and a mineral filler based on aluminium hydroxide, also known as alumina trihydrate. A typical ratio is roughly one third resin to two thirds filler. The material is homogeneous, non-porous and coloured right through, and it counts as a composite material. Corian is the best-known brand; others include HI-MACS, Staron and Avonite. Dutch uses the same English term.
Properties
- Seamless. Sheets are bonded with colour-matched adhesive so the joint is barely visible. A sink or basin can be integrated into the top without a visible seam.
- Non-porous. Moisture, dirt and bacteria cannot soak in, which is why it is popular in kitchens, bathrooms, healthcare and laboratories.
- Repairable. Because the colour runs all the way through, scratches and minor damage can be sanded out.
- Thermoformable. When heated it can be bent, for curved counters or cladding panels.
- Softer than stone. It scratches and heat-marks more easily than natural stone or quartz composite.
Application
- Choose by use. Ideal for seamless vanity tops, reception counters and hygienic work surfaces. In a busy kitchen with hot pans and knives, quartz or natural stone is more forgiving.
- Use a certified fabricator. Bonding, thermoforming and fitting integrated sinks need special adhesives and tools. Check the manufacturer’s warranty conditions.
- Always use a trivet. Never put hot pans straight on the surface.
- Do not cut directly on it. Use a chopping board.
- Keep cleaning simple. Water and a mild detergent will do. Matt finishes can be refreshed with an abrasive pad; high gloss needs more care.
Common mistake: confusing solid surface with quartz composite or HPL laminate. They can look similar, but cannot be joined seamlessly or repaired in the same way.
