Improves bonding strength, flexibility, durability over time and moisture resistance wherever added. Use it as a primer on absorbent substrates, such as aircrete, brittle floor screeds etc. to stabilize those surfaces. A necessary admixture for applications over substrates subjected to intense expansions and contractions since it yields flexibility to both adhesives and grouts.
Dilution ratio with water, from 1:1 to 1:2, depending on the application.
