G4 Pond Seal / Damp Seal is a one component polyurethane which forms a non-porous, tough, durable but flexible seal.  It is browny translucent in  colour. Seals porous substrates such as concrete and brick. G4 will not seal concrete or lightweight blocks, these need to be rendered before application. When used for sealing ponds, any substrate below the water line must be cement rendered. G4 can be used at low temperatures, down to 0°c and in areas of relative high humidity. G4 cannot be used on bitumen of pond liners.

G4 is recommended by all the major polyester resin manufactures as a bonding primer between polyester resin (G.R.P.) and materials such as wood, metal and concrete. It is widely used by roofing contractors when applying glass fibre roofs. Brush on a coat of G4 to the clean base substrate. As soon as it is finger tacky but within 4 hours apply the polyester resin and glass fibre (G.R.P) laminate.
