GCP Bituthene Rubberized Asphalt-Based Mastic 5 Gallon

GCP Bituthene Rubberized Asphalt-Based Mastic 5 Gallon

A rubberized asphalt-based mastic. It has excellent adhesion to structural concrete, masonry, glass-mat-faced gypsum sheathing, and wood and is designed to seal terminations, edges of patches, and overlaps in detail areas. It is an integral part of the Bituthene® Waterproofing System, though it should not be used as a primary waterproofing material. It is compatible with all Perm-A-Barrier® self-adhered air barriers and flashing membranes.

Uses:

• Bituthene Mastic is designed to seal terminations, edges of patches, and overlaps in detail areas. On vertical applications, the mastic must be applied to both the top and bottom terminations.
