Mapei Mapelastic

Mapei Mapelastic cementitious mortar stays flexible down to -20°C, for protecting and waterproofing balconies, terraces, bathrooms and swimming pools.

Best Uses

Mapelastic is a two-component mortar based on cementitious binders, fine-grained selected aggregates, special admixtures and synthetic polymers dispersed in water, blended according to a formula developed in MAPEI’s research laboratories. When the two components are mixed together, a free-flowing mix is obtained which may be easily applied, even on vertical surfaces, at a thickness of up to 2 mm in one single
coat.
Thanks to the high content and quality of the synthetic resins, the cured layer of Mapelastic remains constantly flexible under all environmental conditions and resistant to the chemical attack of de-icing salts, sulphates, chlorides and carbon dioxide. Mapelastic has excellent bonding properties to all concrete, masonry, ceramic and marble surfaces, as long as they are sound and sufficiently clean. This property, together with its resistance to the deteriorating effect of UV rays, a characteristic of this product, ensures that structures protected and waterproofed with Mapelastic have a long service life, even if they are located in areas with particularly difficult climatic conditions, in coastal areas with a saline rich atmosphere or industrial areas where the air is particularly polluted.

Mapei Mapelastic is ideal for the waterproofing and protection of concrete structures, renders and cementitious screeds.

Some application examples include:

• Waterproofing of concrete basins used for containing water
• Waterproofing bathrooms, showers, balconies, terraces, swimming pools, etc. before laying ceramic tile finishes
• Waterproofing of plasterboard, render or cementitious surfaces, lightweight cement blocks and marine grade plywood
• Flexible smoothing layer for light-sectioned concrete structures, including those subjected to minor deformation when under load (e.g. pre-cast panels)
• Protection of renders or concrete with cracks caused by shrinkage, against the infiltration of water and aggressive atmospheric elements
• Protection, against the penetration of carbon dioxide, of concrete pillars beams, road and railway viaducts repaired with products from the Mapegrout range, and structures with an insufficient layer of concrete covering on the reinforcement rods
• Protection of concrete surfaces which may come into contact with seawater, de-icing salts, such as sodium or calcium chloride, and sulphates
