Decadex - proven anti-carbonation coating with a long track record

Flexcrete's Decadex is a water based, permanently elastomeric coating with a proven track record for the protection of reinforced concrete structures from the effects of carbonation. It also provides protection against aggressive atmospheric pollution, chloride ions and water ingress, yet allows damp substrates to breathe without blistering. The product is available in several attractive colours and is also self-cleaning, offering a long lasting, aesthetic finish.

Decadex is a single component, resin rich, high build, anti-carbonation coating based on a synthetic rubber/styrene-acrylic copolymer formulation. It cures to form a tightly adherent, decorative, weatherproof coating with very high diffusion resistance to carbon dioxide, making it ideal for the protection of reinforced concrete structures from carbonation. The cured membrane is permanently elastomeric and does not embrittle or crack on ageing, enabling it to facilitate movements in the substrate and to bridge hairline cracks, giving outstanding durability. The product has been designed to offer low diffusion resistance to water vapour, enabling the free passage of entrapped moisture from the substrate without blistering the coating or weakening its adhesion, whilst still providing a tough, impenetrable barrier against further water ingress. DECADEX is available in a range of attractive colours and its chemical and pollution resistant surface is self-cleaning to preserve its aesthetic appearance.

Advantages of Decadex

Anti-carbonation: Very high diffusion resistance to carbon dioxide.
Elastomeric: Resin rich formulation which cures to form a permanently elastomeric membrane capable of facilitating movements in the substrate and bridging hairline cracks.
Compliance: Approved by the BBA, Certificate No. 92/2837.
Safe: Low hazard, water based product with no flash point. Equipment easily cleaned with water.
Breathable: Low water vapour diffusion resistance allows damp substrates to breathe and dry out without blistering, whilst still providing a tough, impenetrable barrier to further water ingress.
Self-cleaning: Unique water repellency by “beading” removes dirt particles without streaking effect.
Reinforceable: Reinforcement may be incorporated to strengthen the membrane over unstable substrates and joints.
Maintenance: Easily and quickly repaired and maintained.
