Everything You Need to Know About CorkArmour

Discover how CorkArmour’s advanced spray-applied cork coating can help protect, insulate and transform your property.

From fire-resistant performance and weather protection to thermal insulation, acoustic comfort

and breathable moisture management, find answers to the most common questions about CorkArmour.

What is CorkArmour and how does spray cork work?

CorkArmour is a high-performance spray-applied coating made from natural cork granules and advanced resins. Once applied, it forms a seamless, flexible protective finish that combines weather protection, thermal insulation, acoustic performance, breathability and crack resistance in one coating. Cork’s unique cellular structure is naturally lightweight, insulating and sound absorbing, while the coating system creates a durable protective layer for the surface beneath it.

Yes. Fire resistance is one of the important performance advantages available with properly tested spray-cork systems. Cork itself and the complete coating formulation can provide strong fire-resistant performance.

The exact fire classification depends on the specific CorkArmour formulation and application system. For example, other professionally tested cork coatings have achieved ratings including ASTM E84 Class A and Euroclass B-s1,d0, demonstrating that high fire performance is achievable with spray-cork technology.

CorkArmour is designed to provide strong protection against rain, moisture and weather exposure while allowing water vapour to escape.

This combination is one of the biggest advantages of spray cork. Instead of simply creating an impermeable barrier that can trap moisture behind it, a properly formulated breathable cork coating can resist liquid water while remaining vapour permeable.

That helps the building stay protected while still allowing the surface to breathe.

Yes. Cork is naturally thermally insulating because of its cellular structure, which contains millions of tiny air-filled spaces.

When applied as a continuous coating, CorkArmour can help reduce heat transfer and thermal bridging, contributing to more comfortable interior temperatures in both hot and cold conditions.

Spray cork should be viewed as a thermal-performance coating, however, rather than a replacement for thick conventional insulation where a specific building-code R-value is required

CorkArmour is a premium spray-applied cork coating made from natural cork granules and advanced resins. It creates a flexible, resilient protective finish designed to help defend surfaces against weather and environmental exposure while providing thermal insulation, acoustic benefits and breathable moisture management. Unlike conventional rigid coatings, CorkArmour is designed to flex with the substrate while maintaining a durable, attractive finish.

Yes. Flexibility is one of spray cork’s major advantages over many traditional rigid coatings.

CorkArmour is designed to flex with normal surface movement caused by temperature changes, expansion, contraction and minor building movement, helping reduce the likelihood of cracking.

It can be particularly useful over sound surfaces with minor hairline cracking, although structural cracks or unstable substrates should always be properly repaired before CorkArmour is applied.

Spray-cork systems can adhere to a wide variety of properly prepared construction surfaces, making CorkArmour suitable for many residential and commercial applications.

Depending on the specific CorkArmour system, suitable surfaces can include stucco, concrete, masonry, brick, render, wood and certain metal or previously coated surfaces.

Every surface should be inspected before application to make sure it is clean, stable and compatible with the coating system.

In many cases, yes—and this can be one of the biggest advantages of CorkArmour.

A sound existing surface may be prepared and coated rather than completely removed and replaced. This can make CorkArmour particularly attractive for refreshing aging stucco, render, masonry and other exterior finishes.

However, loose, peeling, damaged or unstable material must be repaired first. CorkArmour is a protective coating—it should not be used to hide serious structural problems underneath the surface.

CorkArmour is professionally spray-applied to a properly prepared surface to create a continuous, seamless finish.

The process generally involves surface inspection, cleaning and preparation, necessary repairs, application of the CorkArmour system, curing and final inspection.

Installation time varies depending on the size of the property, condition of the existing surface, preparation required, weather conditions and complexity of the project. A project assessment allows us to provide a more accurate installation timeline. Professional spray-cork systems commonly use multiple coats to build the required finish and thickness.

CorkArmour is designed as a long-lasting protective coating, but service life depends on surface preparation, application quality, substrate condition, exposure and maintenance.

The cost also varies from project to project. Important factors include surface area, existing surface condition, preparation and repairs, accessibility, application requirements, colour/finish and project complexity.

That’s why the best way to determine CorkArmour pricing is with a project-specific assessment and estimate. Other established spray-cork systems offer warranties ranging from 10 to 25 years, illustrating the long-term durability possible with properly installed cork-coating systems; CorkArmour’s own warranty should be stated separately based on your actual warranty terms.
