    ​MasterSeal PG 470 - High performance, elastomeric joint sealant (Pouring Grade)

    How does it work?

    MasterSeal PG 470 is a high grade, polysulphide based sealant possessing outstanding resistance to deterioration due to weathering, ozone, ultraviolet light and attack by chemicals present in industrial atmospheres. It has the ability to withstand repeated cycles of compression and extension over a wide temperature range, and has excellent adhesion properties to all materials commonly employed in building and construction work.
    MasterSeal PG 470 is supplied as 4 litre units of base and catalyst for sealing horizontal joints where pronounced cyclical movement is expected and where the service conditions would be harsh for most common sealants. It is ideal for use in expansion joints in reinforced concrete structures such as bridges, reservoirs, water treatment works, sea walls and roads, etc. It can also be used in floor joints subject to heavy usage where a high resistance to damage is required.
    MasterSeal PG 470 can be used as a bolt hole sealant for the Waboflex REJ / Waboflex SR expansion joints. 

    What is it used for?

    • MasterSeal PG 470 is formulated to be applied using a sealant gun but may be applied by trowel if required.
    • Sealant guns are fitted with conical nozzles which can be cut to suit the joint width. The sealant should be gunned into the joint using an even trigger pressure, cleaning the nozzle occasionally to avoid contamination. Deep joints should be filled in two or more runs, to prevent air entrapment.
    • Once the sealant has been applied, a small timber spatula, soaked in soapy water, should be used to compact the sealant into the joints and to achieve a smooth polished finish. Any masking tape which has been applied should be removed before the sealant cures.
    • Mixing and application equipment should be cleaned immediately.
