Heat Reflective, Anti-carbonation Protection For Masonry Facades.

The Best Elastomeric Wall Coatings Go Unnoticed !

Unlike normal paint, Astec elastomeric wall coatings maintain their elasticity with time. Substrate movement for whatever reason leads to cracks. These cracks are easily bridged during initial application and remain bridged throughout the worst ravages of cold winters and hot humid summers. Other than poor aesthetic appeal, cracks in a buildings protective finish leaves the building vulnerable to premature masonry failures as the cracks allow the ingress of water, chloride irons, (salts), and environmental gases such as, (So2 and Co2) into the masonry substrate and expose the concrete and it’s reinforcement to their potentially destructive effects.

Infrared heat is reflected away from the Building. The IR heat signature was captured by an infrared camera from the rear of two panels during a Solar Radiation Exposure Test. One panel was Astec Energy Star® Low Sheen and the other, a competitor’s premium exterior acrylic. Both panels were identical in colour.

Heat Reflective Coatings for New Construction & Renovation

Masonry Wall retrofit has always been a premature expense to building owners. Where the general integrity of the existing paint finish is sound, excluding unsightly failures over continually moving cracks in the substrate.


Energy Star Dirtguard I.R. Elastic possesses the ability to bridge a forthcoming crack in masonry 31.0 times its dry film thickness. (180 microns dry will accommodate a forthcoming crack of 5.58 mm).


Heat and moisture are the two main contributing factors that accelerate the degradation of exterior coatings. In highly humid, tropical environments, conventional acrylics have been known to last as little as three years by fading from its original depth of colour. Energy Star elastomeric coatings have increased durability and life expectancy compared with conventional paints. After exposure to 2800hrs of UVB 313/Moisture testing, in accordance to ASTM G53-96 the, gloss, depth of colour , adhesion and film integrity remained un-changed, providing a performance increase of more than 400% when compared to a standard exterior acrylic.

Low Temperature Flexibility-Down To -20 deg C

Membranes for dimensionally unstable masonry substrates must have long-term low temperature flexibility. This flexibility is necessary to accommodate thermal expansion and contraction of the substrate caused by rapid freeze/thaw weather cycling. Many products claim elastomeric performance, but do not have this main property of low temperature flexibility that is essential to a truly durable elastomeric coating..
