Bonda Glass G4 Damp Seal
G4 seals damp out of concrete, brick, stone and wood with a non-porous plastic coating that is hard wearing, tough but flexible. Being moisture cured it can be applied in poor conditions, down to 0°C and in high humidity. Three coats can be applied in a day to provide a good base for further decorations. On boats it is useful for priming those areas which are impossible to completely dry out like patches on elm keels and deadwood and in joins between timber and glass fibre where moisture has penetrated. It is a very impressive product.
1 kg will cover approximately 2 sq metres with three coats.
