Mapei Mapelastic

Mapelastic is a Two-component flexible cementitious mortar for waterproofing concrete, balconies, terraces, bathrooms and swimming pools.

Use Mapelastic to waterproof bathrooms, showers, balconies, terraces and swimming pools before 
the installation of ceramic tiles and provide a highly flexible, protective and waterproof coating to 
concrete structures particularly subject to cracking.
Mapelastic seals hairline cracks already present in substrates.

Mapelastic is supplied in two pre-measured components which must be mixed together without 
adding water or other ingredients. The mortar is applied with a trowel onto perfectly clean and 
sound surfaces that have been previously dampened with water.
Mapelastic has excellent bonding properties when applied on concrete surfaces, cementitious 
screeds and render and stone (which must be clean and well attached to the substrate).

Mapelastic can be applied up to 2 mm thick in a single coat. When applying to surfaces particularly 
stressed or crazed, it is essential to embed a 4 x 4.5 mm square-grid Mapenet 150.
To further improve both elongation at failure and crack bridging of Mapelastic, we recommend 
inserting Mapetex Sel, macro-holed non-woven polypropylene fabric.
Mapelastic meets the requirements of EN 1504-2 standards, in compliance with PI, MC?and 
IR?principle, for concrete protection.
Mapelastic also complies to EN 14891 standards.
