ENDURALASTIC^® 10

Hairline cracks are unsightly surface defects that can be found on various exterior masonry surfaces. Enduralastic 10 is uniquely formulated flexible coating that seals and bridges hairline cracks, which provides excellent waterproofing protection against wind-driven rain.

Crack Bridging Test Method: A stucco mixture is prepared using cement, sand, water and lime. The stucco mixture is applied evenly and no more than 1/4" thick over a panel. The prepared panel is allowed to dry for a week. After the panels are cured, the test paint is applied using a brush to the appropriate mil thickness and cured for a week. After a week, the panel is bent over a 5" diameter metal can. The panel is evaluated for any visible cracks on the film. If no cracks are visible then the can is bent over a 4" diameter can. Each portion of the panel is rated on a scale.

Coatings that exhibit good resistance to weathering such as UV light (sunlight) and moisture will maintain their original appearance longer. Enduralastic 10 clearly beats the Regional and National Brands.

Chalking/Binder Degradation Resistance Test Method: Exposure data is necessary for the selection of new materials and improvement of existing materials. The QUV machine reproduces the damaging effects of sunlight by using fluorescent UV lamps. It also uses a hot condensation mechanism that reproduces outdoor moisture similar to dew. The use of QUV machines allows the lab to monitor and evaluate product deterioration in a more controlled manner. Aluminum Q-panels are cleaned using acetone to remove any impurities. All panels are primed with Ultra-Grip Premium using an airless sprayer and allowed to dry overnight. The following day, each panel is coated using a 30 mil clearance square applicator. After seven day cure time, each panel is read for gloss, color readings, and photographed before exposure. The panels are mounted in snap-ring holders and placed into the QUV accelerated weathering machine. The QUV machine is programed to cycle between four hours of UV light, with irradience of 0.68, and four hours of condensation, 40^° C. The panels are exposed to these conditions for a total of 1250 hours. Every 250 hours, each panel is evaluated for gloss retention, color retention, blistering, chalking/binder degradation, cracking/flaking and adhesion.
