Brick Wall Expansion Joint Sealant

Joint sealants and related materials control joints in concrete masonry construction are classified as butt joints where the sealant is exposed to cyclical tension and compression as the joint expands and contracts.

Brick wall expansion joint sealant.

Polyurethane mortar joint sealant is a construction grade crack sealant specifically designed for repairing brick and block mason joint. To control the expansion and protect the wall structure from cracking under pressure masons install vertical control joints at specific locations. Colorseal seismic colorseal watertight primary seal in wall expansion joints a wall expansion joint seismic colorseal colorseal is a silicone coated precompressed primary seal for high movement wall joints. These joints will absorb the pressure created by the expansion by giving the masonry wall flexible space to expand.

Seismic colorseal ensures watertightness in vertical plane structural seismic and abutment joints in virtually any substrate. It seals and waterproofs the crack which helps to prevent further damage.

Repairing and sealing horizontal and vertical expansion joints is a project that can be successfully achieved with the right tools materials and proper surface preparation.

Expansion joints must be sealed with a flexible sealant like quikrete self leveling polyurethane sealant or quikrete non sag polyurethane sealant or an expansion joint strip to prevent water from penetrating the joint and deteriorating the sub base. Sold as 3 pack.
