MAPECRETE LI HARDENER

Liquid surface treatment with densifying effect for new or old concrete floors and concrete surfaces finished with mineral hardener.

DESCRIPTION

Mapecrete LI Hardener is an aqueous solution based on modified lithium silicates, developed in the R&D MAPEI laboratories, used for the surface treatment of internal and external, cement based supports.

TECHNICAL CHARACTERISTICS

Mapecrete LI Hardener penetrates into the pores of the substrate and reacts with the free lime that is normally produced during the hydration phase of the cement. This reaction produces highly resistant insoluble hydrated calcium silicates which increase the compactness and the strength of the cement matrix. The treated surface is easy to clean and maintain.

Mapecrete LI Hardendr complies with JC/T 2158 standard.

ADVANTAGES

ease of use and application;

the treated surface is easy to clean and maintain;

improves the aesthetics of the treated surface by making it slightly shinier and protecting it from the formation of stains and efflorescence;

increases the durability of concrete flooring;

reduces the phenomenon of alkali-aggregate reaction (pop-out), in presence of alkali-reactive aggregates in the substrate;

protects from de-icing salts, weathering, and freeze-thaw cycles.

CONSUMPTION

0.2-0.4 kg/m² Product consumption is strongly influenced by the type of support, its absorbency and the ambient conditions during the application .

PACKAGING

25 kg jerrycan.
