This invention provides a sealing material which comprises a layer of elastomeric sealant having a cone penetration from about 100 to 350 (10-1 mm) and an ultimate elongation of at least 50% and disposed on a surface thereof an air drying or air curing material which sufficiently adheres to the surface of the elastomeric sealant to permit placement of the elastomeric sealant on a substrate and which reduces the surface tack of the elastomeric sealant. |
