    Sikalastic® M 388 (formerly known as MasterSeal® M 388) - Solar radiation reflective waterproofing system top coat

    How does MasterSeal M 388 work?

    MasterSeal M 388 is designed for use as a topcoat in solar radiation reflective waterproofing membrane system. It has high solar reflectivity which results in dark colours having the same reflectance as white. This results in the surface of the roof being cooler and reduces the transmission of heat through the roofing material. Generally it is applied n body coat (MasterSeal M 378). It is water based with high performance dispersions to provide a flexible, elastomeric waterproofing membrane. The cured coating is tough, durable and seamless.
