Description

Del-Val 241 Silicone Roof Patch is a one-part, high solids, low VOC silicone elastomeric flashing mastic specifically designed for use in sealing roof penetrations, seams, curbs, flashings and other areas on the roof where water infiltration is possible. It works well on roofs that were previously coated with Del-Val 320 Silicone Coating. Once cured, this liquid applied silicone mastic provides a durable, seamless, flexible, waterproof membrane that resists lateral movement, shear and will allow for normal expansion and contraction.

Uses

Del-Val 241 Silicone Roof Patch provides a protective barrier for multiple applications where water infiltrates a roofing system. The most common areas include seams, pipe boots, curbs, flashing details, penetrations and exposed fasteners.

Preparation
