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.
What is MasterSeal 470 recommended for?
MasterSeal 470 is used in joints in critical situations in many types of buildings and structures:
- bridges, tunnels and other civil engineering structures
- precast concrete paneling, and high rise buildings
- concrete and brick foundations, retaining walls and bridge abutments,
- reservoirs, water treatment works, sea walls and roads
- secondary containment areas
- wet areas such as kitchens, laundries, bathrooms and showers, beneath tiles
