Combines adhesive activated by water and drywall paper. Without the usual initial coat of compound, this perforated tape dries in 30 to 40 minutes in most climates. Contains mold and mildew inhibitors to prevent bacteria growth at the joint. Needs no initial compound, and adheres directly to drywall. Heavy-duty high tensile strength paper resists tearing and distortion. Creates an air tight bond upon drying and reinforces corners in minutes, preparing wall for the application of wall treatments. Repositionable, just moisten and adjust.
