Multi-Purpose Joint Sealant Adheres to Damp Surfaces

Kemper System GreatSealKemper System America Inc. offers GreatSeal PE-150, a high-performance, single-component, multi-purpose joint sealant designed for long-lasting weathertight seals. According to the manufacturer, it is ideal for sealing joints in roofing, walls and masonry, as well as gaps around penetrations, flashings, windows and doors.

Based on a polyether sealant, GreatSeal PE-150 contains no solvents and very low VOCs. The multi-purpose indoor/outdoor sealant exhibits excellent weathering properties with a service range of 200oF to minus 40oF (93oC to minus 40oC), movement capability of +/- 25 percent, and zero shrinkage.

According to the company, the product adheres even on damp surfaces. It can be applied in cold weather, and in most cases, without a primer. It bonds aggressively to most building materials, including wood, vinyl, glass, fiberglass, foam insulation, asphalt, modified bitumen, EPDM, PVC, PIB rubber, and Kynar coatings, as well as painted, galvanized and anodized metals.

GreatSeal PE-150 is part of a family of construction sealants from Kemper System. The GreatSeal brand also includes GreatSeal LF-500 Liquid Flashing compatible with Roof Guardian elastomer-based roofing products, and GreatSeal LT-100 polyether Liquid Tape compatible with Wall Guardian FW-100A, a liquid-applied fibered acrylic air barrier. All three brands are in the STS Coatings line, acquired by Kemper System America in 2016.
