1. Creating the Mixture

The process begins with blending high-quality acrylic resin (or sometimes polyester) with alumina trihydrate (ATH), a mineral filler that adds durability and fire resistance. Pigments are then added to create a wide variety of colors and patterns, including natural stone-like effects.

2. Curing and Forming

Once mixed, the raw material is poured onto a moving belt or into molds. The sheets are then cured in an oven, where heat triggers a chemical reaction that forms a solid, homogeneous slab. This ensures consistency in strength and surface quality.

3. Fabrication and Shaping

After curing, the sheets are cut, sanded, and polished to the desired thickness and finish. Acrylic solid surface can also be thermoformed, allowing it to bend into curves and custom shapes. Fabricators can use standard woodworking tools like routers and sanders, which makes it highly versatile for seamless countertop and sink installations.

4. Final Product

The result is a non-porous, hygienic, and durable surface that is ideal for:

• Kitchen countertops and bathroom vanities
• Sinks and integrated basins
• Wall cladding and shower panels
• Furniture, signage, and decorative designs

Because it is non-porous, solid surface resists stains, bacteria, and moisture, making it a safe and low-maintenance choice for both homes and high-traffic commercial spaces such as hospitals, offices, and retail stores.

Acrylic vs. Polyester Solid Surface

Not all solid surfaces are made the same. Acrylic-based solid surface offers superior durability, thermoforming ability, and UV resistance, making it the premium choice. Polyester-based solid surface may be more affordable and glossy, but it is less flexible and more brittle. At Kstone, we specialize in acrylic solid surface because it ensures long-lasting performance and reliability.
