Expanding foam ( up to 30 times ). Fill & Fix gaps and holes
A one component, moisture curing,polyurethane foam which expands to form a rigid sealant on curing.
Has very good resistance to water, benzene, oil, cleaning solvents, weak acids and alkalis when fully cured. It does not rot or decay and resists fungus.
It may be plastered over depending on size - small areas need no preparatory work whereas large areas need a priming coat.
A 750ml aerosol will produce approximately 35 litres of expanded foam.
Not resistant to ultra violet rays and should not be exposed to prolonged sunlight.
It may be painted over when cured with an oil based or emulsion paint.
