Tech Shield System Component

Efflorescence Control Agent, Integral Water Repellent

Tech Shield Mortar Admixture is formulated to provide integral water repellency and enhanced efflorescence control for masonry mortar and similar cementitious materials. Used properly, this unique admixture chemically reacts with cement and its water repellent components form a permanent bond within the mortar. This ensures lasting resistance to wind-driven rain, moisture migration, and ‘wicking’. Tech Shield Mortar Admixture is an essential component of the Tech Shield Water Repellent Admixture System for concrete masonry construction.
