Polyflex is a one part moisture curing polyurethane sealer which stays elastic when dry and is ideal for use to seal surfaces permanently exposed to water. It is therefore ideal for sealing round pipe joints and flanged fittings such as bottom drains in liner ponds. It is also UV resistant so will not go brittle with time.

Not suitable for use in swimming pools as it is affected by Chlorine.  Can be painted when dry and does not stain brickwork. Colour black.
