## Overview

CHIMNEYRX Masonry Crack & Joint Filler is a brushable elastomeric sealant designed to repair exterior mortar cracks up to 1/8" wide on chimneys, brick, and stone masonry. It forms a clear, waterproof barrier that prevents leaks and weather damage, offering a cost-effective alternative to traditional masonry repairs.

## Description

Chimney RX Crack & Joint Sealant is brush-able elastomeric sealant for mortar joints used to repair exterior cracks in mortar on chimneys, brick walls and between concrete or stone masonry units. The product seals larger cracks and other defects that cannot be corrected with water repellents alone. Crack & Joint Sealant seals crack up to 1/8" wide on brick faces and at mortar and brick joint interfaces to provide waterproof protection. It dries to a clear, translucent, milky film. Crack & Joint Sealant prevents water infiltration and subsequent damage, yet allows water vapor to escape. When applied to a properly prepared wall or chimney surface, Crack & Joint Sealant can solve tough leak problems without the expense of truck pointing or surface grouting. Use ChimneyRx Masonry Crack and Joint Sealant along with ChimneyRx Masonry Chimney Water Repellent to provide maximum protection. A one pint container will treat the mortar joints surrounding approximately 110 standard bricks, or approximately 25 square feet of wall surface.
