COATING FOAM – EPS FOAM

Examples of Foam Coatings

We have multiple methods of hard coating foam for both exterior and interior applications. Our most common exterior and interior hard coats include urethane hard coat, polyuria hard coats, cementitious coating, fiberglass, and acrylic limestone. There are significant differences in the properties, costs, looks and durability of many of the coatings. Coatings cannot have any solvents in them, or they will dissolve certain foams like expanded polystyrene (Styrofoam) unless there is a barrier constructed on the foam.

Polyurethane Coatings / Polyurea Coatings:

Polyurethane coatings are versatile and can be formulated to provide different levels of hardness and flexibility. They can be applied as a spray-on coating and cure rapidly, forming a tough, seamless membrane over the EPS foam surface. They offer good durability and weather resistance, making them suitable for outdoor applications.

Cementitious Coatings:

Cementitious coatings are composed of cement, sand, and polymers. They are applied as a slurry or mortar and can provide a durable, fire-resistant finish for EPS foam.

Limestone Acrylic:

Seemingly indestructible, our limestone acrylic aggregate can be hand applied, sprayed and extruded, leaving a thick covering of stone like material that has such a beautiful natural stone look that many people never coat it making it a maintenance free product that lasts indefinitely.

Acrylic Coatings:

Acrylic coatings are water-based and environmentally friendly. They can be applied as a brush-on or spray-on coating and provide a hard, smooth finish. Acrylic coatings are often used for artistic or decorative applications.

Fiberglass Reinforced Plastic (FRP) Coatings:

FRP coatings consist of a layer of fiberglass mat or fabric embedded in a resin matrix. They offer high strength and impact resistance and can be applied as a laminate over EPS foam surfaces.

Epoxy Coatings:

Epoxy coatings offer strong adhesion to EPS foam and provide a hard, glossy finish. They are often used for decorative applications or where a high level of chemical and abrasion resistance is required.

Silicone Coatings:

Silicone coatings provide a flexible, waterproof barrier over EPS foam surfaces. They are often used for applications where movement or vibration is expected, such as in building construction or marine applications.
