MasterSeal 521 is a two-component, acrylic modified, cementitious coating that requires only on-site mixing to form the ideal product to provide a durable, waterproof coating to re-surface concrete, masonry, and most other construction materials. MasterSeal 521 imparts the natural concrete appearance.
MasterSeal 521 provides an effective barrier to water-borne salts and atmospheric gases.
MasterSeal 521 is designed for application by brush or spray; however for filling larger depressions, it can be mixed to stiffer consistency and applied by trowel.
