Two-component, high-flexibility cementitious mortar, applied by brush or by roller, for waterproofing concrete surfaces such as balconies, terraces, basins and swimming pools, and for protection against the penetration of aggressive agents. Mapelastic Smart is used to form highly flexible, waterproof and protective dressings on concrete structures, even those subject to cracking. Mapelastic Smart may also be used to cover up micro-cracking in concrete or render. Mapelastic Smart is supplied in the form of two pre-dosed components, which must be mixed together without adding either water or any other ingredient. Mixing ratio: A : B = 2 : 1. The mortar is applied by brush, roller or spray-rendering machine on surfaces which must be perfectly clean and solid, and which have been dampened with water beforehand. With Mapelastic Smart, a levelling layer of up to 2 mm thick may be applied in one single coat. If the product is to be applied on surfaces which are highly stressed or which have micro-cracking, 4 x 4.5 mm Mapenet 150 must be inserted. To further improve both elongation at failure and crack bridging of Mapelastic Smart, we recommend inserting Mapetex Sel, macro-holed non-woven polypropylene fabric. Mapelastic Smart meets the requirements of EN 1504-2 standards, coating (C), in compliance with PI, MC?and IR?principles, for concrete protection.
Consumption approximately 1.6 kg/m2 per mm of thickness, if applied by brush or roller; approximately 2.2 kg/m2 per mm of thickness, if applied by spray.
