More information on Acme-Shield®
The potential for efflorescence is found in all building materials*, i.e., cement, sand, aggregate, and water. To some degree, they contain water soluble salts that react with water to form efflorescence.
Efflorescence occurs on the surface of masonry as a whitish, powdery substance. Water entering the block through its pores comes in contact with calcium hydroxide (water soluble salts) as the result of the reaction between cement or lime and water. Upon drying, the calcium hydroxide (water soluble salts) leaches or migrates to the surface of the block, combines with carbon dioxide in the air, forming the calcium carbonate—the whitish substance known as efflorescence.
ACME SHIELD is unique; it accomplishes efflorescence control in two ways:
1. It coats the materials that form the cement paste (cement, sand, and aggregate) making these materials repellent to water, and
2. It combines with the water soluble salts and converts them to chemically inactive compounds not readily given to efflorescence. To our knowledge, ACME SHIELD is the only integral water-repellent that combats efflorescence in this effective manner.
* The most common salts found in efflorescence are sulfate and carbonate compounds of sodium potassium, calcium, magnesium, and aluminum.
