MasterSeal 550 is a two-component aqueous modified concrete mixture covering that only requires on-site mixing to waterproof and resurface cement, stonework, and most other construction equipment
MasterSeal 550 creates an impermeable, flexible covering when sprayed with a stiff brush, roller, or trowel. Waterborne salts and ambient gases are effectively blocked.
MasterSeal 550, when sprayed as a fluid, creates a long-lasting, seamless, waterproof membrane for roofing and foundation protection.MasterSeal 550 is made consisting of a powdered mixture of chosen specifically cementitious materials, sand, and reactive additives, as well as a fluid element made up of blended acrylic copolymers and wetting agents.
