Method and assembly for protecting a substrate.

摘要

A method and apparatus are described for supplying a body of sealant (10) (preferably a gel), having a cone penetration of 100-350 (10<-><1> mm) and an ultimate elongation of at least 50% to a substrate. The sealant (10) is provided as a strip that is wrapped around a smaller diameter portion of an elongate applicator (2). The applicator (2) has a tapered region (6) extending from the region (4) where the sealant (10) is wrapped. The sealant (10) is rolled along the tapered region (6) onto the substrate (14). Thus the sealant (10) is deformed and its sealing capability increased.
