Spray Applied Liquid Rubber Roofing
Spray applied liquid rubber roofing systems are increasingly used for large commercial roof refurbishment projects where seamless waterproofing, rapid installation and minimal disruption are critical.
Unlike traditional roofing systems that rely on overlapping sheets or multi-layer installation, spray-applied liquid rubber creates a continuous waterproof membrane across the entire roof surface.
The system forms a seamless elastomeric coating that adheres directly to the existing roof structure, eliminating joints and reducing potential failure points.
Spray applied liquid rubber is particularly suited to large commercial roof structures where installation speed and consistent membrane thickness are essential.
How Spray Applied Liquid Rubber Roofing Works
Spray applied liquid rubber systems use specialised equipment to apply a liquid waterproof membrane directly to the roof surface.
The material is sprayed across the substrate where it rapidly cures to form a seamless waterproof layer.
Because the membrane is applied as a liquid, it conforms to the surface beneath, sealing joints, penetrations and complex details.
This results in a fully adhered waterproof membrane that protects the roof structure from water ingress while remaining highly flexible and resistant to temperature fluctuations.

Frequently Asked Questions
What is spray applied liquid rubber roofing?
Spray applied liquid rubber roofing is a two-component waterproofing system applied using specialist spray equipment. It cures to form a seamless elastomeric membrane directly on the roof surface, eliminating joints and providing continuous waterproof protection.
What size roofs is spray applied liquid rubber suitable for?
Spray applied liquid rubber is designed for large commercial and industrial roof areas, typically from 300 m² upward, where rapid installation and consistent membrane thickness are required.
How fast can spray applied liquid rubber be installed?
SprayGrade is specified at approximately 600 m² per day under suitable conditions using the required spray equipment. Actual output depends on preparation, detailing, access and weather.
Can spray applied liquid rubber be used on asbestos roofs?
Yes. Spray applied liquid rubber is commonly used as part of an asbestos roof encapsulation strategy, sealing and protecting deteriorating asbestos cement roof sheets without the disruption of full removal.
