VISCOSITY MODIFYING ADMIXTURE FOR MASONRY

Specco Masonry Aid #190 is a neutral, biodegradable, liquid chemical additive that is designed to prevent or reduce bleeding, segregation, shrinkage and cracking that are commonplace in in mortar, stucco, plaster and grout mixes. Masonry Aid #190 may be used as direct or partial replacement of lime or in addition to lime, in mortar, grout and coating mixes.

Masonry Aid #190 reduces capillarity tube formation, efflorescence, hair-line cracks and increases bond strength. Masonry Aid #190 eliminates surface streaking and intensifies color shades in mixes containing iron oxide colorants.
