High Performance Membrane Paints

High Performance Membrane Paints

Building substrates expand, contract and move. Architectural coatings must cope with this, and perform in the harshest climatic conditions.

That’s why ROCKCOTE developed Armour Flex and Armour - our most advanced high performance membranes ever. These heavy duty, flexible, high-build coatings are formulated specifically for the Australian climate.

Warranted performance and durability make Armour Flex and Armour vastly superior options to standard exterior paint and alternative standard membranes.

Can be used to give the ultimate performance finish to ROCKCOTE Coloured Render Systems. Exceptional dry-film thickness and flexibility combine to deliver superior crack-bridging.

They also deliver a beautiful alternative to much thinner standard paints for residential and commercial properties. Particularly suitable for high-rise developments and properties requiring easy maintenance.

Understanding crack-bridging performance

The best protection against cracking requires both thickness and flexibility. ROCKCOTE High Performance Membranes are formulated for both thickness and flexibility and as a result deliver outstanding crack-bridging capability.

Unsuitable paints will break down and result in hairline cracks. ROCKCOTE Armour seals, protects and bridges hairline cracks.

Body corporate refurbishment: Armour Low Sheen

ROCKCOTE Armour is a heavy duty, highly flexible, exterior wall paint, designed specifically for harsh Australian conditions. It is an ideal exterior paint for commercial, body corporate and home exterior paint projects. More durable than a standard exterior paint, Armour has been formulated with both thickness and flexibility that help to bridge minor cracking. Available in Low Sheen and Matt.

ROCKCOTE Armour Flex is a high build, high performance protective coating. It is a water resistant and highly flexible acrylic membrane that can be applied by nap roller, texture roller, brush or spray gun. ROCKCOTE Armour Flex is ideally suited to applications that require a superior level of protection, such as high rise buildings, commercial buildings and areas of high coastal exposure.


ROCKCOTE Armour Clear is a clear acrylic finish developed to provide added resistance against water ingress, mould and grime pick up and retention over many ROCKCOTE aggregate textures and applied finishes. ROCKCOTE Armour Clear appears milky white when wet, then dries to a clear lusterous finish, that will enhance and protect
