Masterseal 300H 

Masterseal 300H is a flexible, elastomeric coating based on acrylic co-polymers.  Applied as a liquid it cures to form a durable, protective, waterproof membrane.  It is a single component emulsion containing inert pigments and has a brushable consistency.  Masterseal 300H exceeds all the requirements of a coating that resists carbonation and prevents chloride ion ingress.
