1kg G4 Sealer£23.40 £19.50G4 pond sealer is applied to concrete ponds to prevent water from penetrating the concrete. Additionally it prevents toxic substances such as lime leaching into the pond. G4 pond sealer is polyurethane base, and can be applied directly to concrete, bricks and porous stone. Ensure that the surface is dust free and dry. It cures within 6 hours. Full mechanical hardness is achieved after 24 hours and chemical resistance after 72hours. It may be applied at temperatures from 00C. Normally 3 layers is applied for a durable seal. Coverage is approx 550gm per sq.m for the 3 applications. Learn More

G4 sealer is a moisture curing polyurethane liquid that forms a non-porous coating on concrete, brick or porous stone. G4 utilizes the moisture in the air and substrate as a catalyst to cure and harden. We recommend 1 layer of G4 as a primer on concrete and brick to promote adhesion between the Fibreglass lining and the concrete surface. Application rate is 250gm/m2.
