MasterSeal 470 - High performance, elastomeric, polysulphide joint sealant available in non-sag or pourable grades

How does MasterSeal 470 work?

MasterSeal 470 is a high grade, chemically curing, two component polysulphide based sealant that forms a tough, flexible, durable, rubber like material which adheres to most common construction surfaces and provides fully waterproof seals in joints subject to a high degree of deformation or continuous cyclic movement. The product is supplied in two version:

MasterSeal GG 470 is a non-sag, gun grade version supplied in a single 4 liter composite pack for sealing vertical and overhead joints and for general application.

MasterSeal PG 470 is a pouring grade version supplied as 5 liter units of base and catalyst for sealing horizontal joints.
