Liquid admixture for reduced efflorescence of mortars and grouts
BATIMIX Anti-Efflorescence M-870 is a ready-to-use liquid admixture designed from a balanced blend of stearate chemicals to significantly improve mortar surface appearance by eliminating any potential risk of efflorescence. Upon request, this product can be supplied in powder form.
Efflorescence is a crystalline deposit, usually white, of water-soluble salts on the surface of masonry. The principal objection to efflorescence is the appearance of the salts and the nuisance of their removal.
A combination of circumstances is necessary for the formation of efflorescence. First, there must be a source of soluble slats which may result from the masonry construction materials and elements. Second, there must be moisture present to pick up the soluble salts and carry them to the surface. Third, evaporation of hydrostatic pressure must cause the solution to migrate, thus leaving crystalline deposits on the masonry surface. If any one of these conditions is eliminated, efflorescence will not occur.
Applications using BATIMIX Anti-Efflorescence M-870 include all types of mortars and grouts used for masonry and repair such as plastering, rendering, patching, and pointing.
Mortars prepared with BATIMIX Anti-Efflorescence M-870 are characterized by the following:
In the plastic state:
In the hardened state:
From 0.3% to 1.4% of cement weight, depending on the expected level of efflorescence.
White liquid
