What Is Cork Spray?

Cork is widely used as a stopper for wine bottles. However, this is only the beginning of its potential. When cork granules are processed into a sprayable coating, they can enhance the look and function of residential and commercial buildings.

ThermaShield—a leading manufacturer of cork spray products in Phoenix, AZ—uses an innovative formula for producing superior cork spray products. This includes both wall and roof coatings.

Aesthetic Enhancements for Your Residential or Commercial Building

ThermaShield’s cork spray can be applied directly over your current exterior or interior. In fact, cork spray instantly seals cracks and gaps. Thus, it makes your home more pest-resistant. Plus, cork spray will boost your home’s curb appeal.

At ThermaShield, we offer a wide selection of colors. In fact, you can choose from shades of brown, tan, gray, white, red, green, and many more. If you don’t see something that suits your décor preferences, just ask us about mixing your own custom color.

  • Ideal as a top coat on concrete or bricks to enhance aesthetics and durability
  • Appropriate top coat for stucco or other siding materials
  • May be used to add insulation to tanks and silos
