RectorSeal’s Metacaulk 1200 White Spray is a versatile mastic-grade sealant designed to facilitate efficient installation across extensive joint runs. This sprayable, brushable, and trowelable product excels in filling gaps and voids in applications such as top-of-wall joints, curtain wall perimeters, and expansion joints. Its self-leveling properties make it ideal for horizontal surfaces, while the caulk grade allows for easy application using a caulk gun or trowel.
