FEBRUARY 2015 | 41 PHOTOGRAPHY COURTESY DURABOND PRODUCTS LTD. Restoration Products & Services known for stucco and EIFS," says Gary Osmond, techni- cal manager at Durabond. Ecto-Sil also has the potential to improve the ther- mal performance of the building envelope because, as Osmond notes, the coating, although breathable, "stops air from leaking in or out of the building." Another recently introduced coating that Osmond points to is called Acrotel EC-A. This Durabond prod- uct is designed to protect concrete structures against moisture intrusion and carbon dioxide diffusion, to prevent the carbonation of the concrete and increased risk of corrosion of the reinforcing steel. When prop- erly applied, the coating is about 16 mils in thickness, and equivalent, Osmond says, to 40 centimetres in con- crete thickness. "All these [coatings] have been devel- oped to stop water intrusion and stop heat loss due to air movements," says Osmond, pointing to this and the company's other protective coatings. Dryvit Systems Canada Ltd. is another supplier of EIFS with a range of decorative and protective coat- ings, along with additional products for the repair and maintenance of its Outsulation system or other EIFS. The company offers decorative coatings for adding the glow of renewal to older buildings. All are designed to be dura- ble, weather-resistant and include dirt pick-up resistant (DPR) chemistry. Its Weatherlastic line of protective coatings are also DPR, elastic and water-repellent and designed to help bridge hairline cracks as well as protect cementitious and masonry surfaces and existing EIFS, says Daniel Schlegel, marketing manager at Dryvit. Dryvit also supplies elastomeric patching com- pounds used to repair surface cracks in stucco, con- crete, cement plaster, masonry and EIFS walls. Demand for concrete and masonry repair products may have something to do with the recent growth of the concrete restoration systems (CRS) branch of Mapei Inc. within the North American market. The company's CRS products help repair damaged concrete on both com- mercial and industrial buildings as well as infrastruc- ture settings like bridges and wastewater systems. This February, the company is launching its new Elastocolor paint coatings. "Climate and weather- aging affect buildings and this new coating will make them look new and protect them from fungus, mois- ture, chlorides and atmosphere weathering. It has low dirt retention and is available in 25 standard colours," says Roger Pratt, the business manager for concrete restoration systems at Mapei. Besides a primer, the product line includes a elasto- meric acrylic coating and a high-build rigid acrylic coating. Some proprietary products and systems can dou- ble as coating or cladding for a new building or as part of a makeover for an older or heritage building.
