Exterior Wall Coatings

Spray cork is a blend of cork granules and water-based resins that creates a natural, flexible, and insulating coating when sprayed onto nearly any surface. Cork is a natural thermal insulator sourced from the bark of cork oak trees. The bark is harvested without harming the tree, making cork a highly renewable resource. Once applied, the cork coating adheres to stucco, concrete, metal, wood, and other building materials, forming a seamless layer of cork insulation.

Spray cork can be applied to the outside or inside of homes and buildings. Because cork is a natural thermal and acoustic barrier, this coating reduces energy costs, improves comfort, and adds value.

Cork is a highly flexible, breathable, and waterproof material. It expands and contracts with temperature changes, making it ideal for exterior building surfaces exposed to UV rays and weather fluctuations. As a building material, cork is also non-toxic and VOC-free so that it won’t emit harmful chemicals.

Because cork is harvested from cork oak trees every 9–12 years, it’s considered a highly renewable resource. It requires no tree felling, and the process supports long-term forestry and eco-friendly harvesting methods. These traits position cork as a standout option in renewable building innovation, particularly cork insulation.

The durability of cork spray is a significant benefit. It provides a thermal barrier and enhances surface durability, giving you peace of mind about your investment.

• Thermal insulation: Cork is a natural solution for thermal insulation and waterproofing, helping to reduce energy costs year-round.
• Acoustic insulation: Spray cork offers soundproofing benefits, especially for homes in urban areas or near busy streets.
• Durability: Spray cork resists cracking, fading, and UV rays.
• Eco-friendly: Cork is a renewable, non-toxic, and breathable material that provides excellent building insulation.

Cork insulation’s flexibility in application allows it to adapt to various surfaces and structures. It adheres to almost any surface, including paint or stucco, concrete, brick, or wood.

• Aesthetics: Available in various textures and colors, cork spray can give your building a fresh, modern appearance similar to stucco.

These features make spray cork a go-to option for exterior surfaces, walkways, and patios, providing beauty and functionality.

Unlike traditional paint or stucco, cork spray provides a breathable and insulating barrier. Paint often peels and fades under UV rays, while stucco can crack with temperature shifts. Cork offers flexibility, thermal conductivity reduction, and protection against moisture while maintaining its color and integrity as a natural cork product.

Moreover, cork spray is water-based and non-toxic, unlike many traditional options containing VOCs. This makes it a superior choice for homeowners seeking a renewable, environmentally responsible exterior solution.

Yes. Cork spray isn’t limited to exterior applications. It also performs well on interior walls where thermal cork and acoustic insulation are desired. Cork directly applied to internal and external walls creates a barrier that reduces thermal conductivity and dampens noise. This application is especially valuable in shared living spaces, home offices, or rooms adjacent to mechanical systems.

Cork spray can be applied to:

• Cork products can enhance exterior walls (stucco, wood, metal) by improving insulation and aesthetics.
• Interior walls (for insulation or soundproofing)
• Patios and walkways (anti-slip texture)
• Pool decks
• Decks and outdoor structures
• Garages and workshops can benefit significantly from using cork products for insulation.

It works on nearly any surface and is a smart upgrade for new construction and renovation projects.

Cork is naturally resistant to UV rays, temperature shifts, and moisture. Its flexibility allows it to expand and contract without cracking, making it ideal for exterior applications in both hot and cold climates. Because it’s waterproof and breathable, cork coating prevents mold growth while allowing walls to release trapped moisture, maintaining the integrity of the building envelope.

Yes, cork spray is environmentally friendly. It’s made from a renewable resource, harvested without harming trees. The spray formulation uses water-based resins and contains no lead paint, making it safe for applicators and residents. Additionally, the cork stopper industry uses only part of the cork bark. Spray cork reuses leftover cork granules, reducing waste and maximizing the utility of harvested materials. Choosing cork spray is a responsible and proud choice for your building needs.
