Firefly Intumastic is a water based acrylic sealant, which is available in white. It can ber over-painted with oil or water based paints. For small linear gap seals we would recommend the use of polythene backing rods to ensure maximum economy in use and to form the correct profile to the seal to allow movement without forcing the seal out of the gap. In addition to its building approvals, Intumastic has full IMO and Lloyds Certification for a range of marine applications.
Also comes in sausages and 5 litre brush grade Tubs.
