Acrylic vs Elastomeric

Elastomeric is a generic term for “rubber-like” roof coatings. Waterborne, acrylic coatings are the most popular. There are many types of elastomeric roof coatings such as acrylic, butyl, polyurethane or silicone.

Types of Elastomeric Coatings

Acrylic Elastomeric Coatings

This water-based roof coating is widely used on pitched metal roofs. It can be economically tinted to any custom color. Easy clean up with water makes it a popular choice for do-it-yourselfers. Acrylic refers to the polymer used in the coating. It is similar to the acrylic resin used in latex house paint but that’s where the similarity ends.

Butyl Elastomeric Coatings

A solvent-based, vapor barrier roof coating with extremely high elongation. It is commonly used over sprayed polyurethane foam in cold storage applications.

Polyurethane Elastomeric Coatings

Solvent based roof coating offers good tensile strength and ponding water resistance. Maybe be directly applied as a base coat for low slope roofs such as EPDM, TPO without primer.

Silicone Elastomeric Coatings

Solvent based roof coating has excellent weatherability and UV resistance. Excellent finish coat for polyurethane coatings. They may also be used for rainwater catchment systems.
