Tuforte Kaltech Arear

Tuforte Kaltech Arear is a natural hydraulic lime (NHL) mortar, developed to promote a sanded finish in conservation works, rehabilitation of old buildings, sustainable construction or bioconstruction. Applicable on facades, walls and ceilings, in outdoor or indoor environments, being one of the products that integrates the kaltech renew, kaltech re-thermic, kaltech re-board, kaltech bio-thermic and kaltech bio-board construction systems.

Promotes a natural sanded finish on lime-based coatings, such as Rebetop Kaltech 2A4, Rebetop Kaltech 1A2, Topcola Kaltech Therm TK, thin reinforced coatings (RDA), and corrects pathologies related to texture or planimetry defects.
