Black colour finish

G4 is a moisture cured pond paint that forms a non porous, durable but flexible seal on concrete, brick and porous stone. It will not seal concrete or lightweight block, these will need to be rendered first. We advise that all surfaces below water are rendered.

When using a coloured G4 it is best to apply 2 coats of clear G4 1st and then 2 coats of colour on top. The will save you money.

Usage guide

Clear G4 = 410g per square metre(for 2 coats)

G4 Colour = 400g per square meter(for 2 coats)
