Marble Restoration with Opal Luxury Surfaces: Protect and Shine

WEATHERCAP is a patented joint protection system made of soft lead. It is installed with sealant in masonry joints to cover and protect the sealant from environmental exposure and building movement. Its flexible nature allows it to adapt to joint changes, preventing cracks and moisture penetration and extending the seal's life.

The system is ideal for weatherproofing vulnerable masonry joints in various applications. Common uses include protecting joints on copings, parapets, cornices, belt courses, window and door lintels, and entrance steps. It is widely used in both new construction and historic restoration projects to prevent water damage.

Absolutely. WEATHERCAP is specified in the U.S. General Services Administration (GSA) Historic Preservation Technical Procedures. It has a proven track record on numerous national landmarks, including the Washington Monument and U.S. Supreme Court, making it a trusted solution for preserving historic masonry.

Type A caps have a flat configuration and are designed for joints where masonry units are in the same plane, such as the top joints of copings or lintels. Type B caps have a 90-degree cove shape and are used for right-angle joints, like where a projecting lintel or water table meets a vertical wall.

WEATHERCAP products are made from a soft lead composition. This material is chosen for its unique properties: it is highly flexible, durable, and resistant to corrosion and mold. Its softness allows it to adapt to building movement without failing, and the surface quickly oxidizes to a neutral grey that blends with masonry.
