  • Product Details

    ChimneyRx Masonry Chimney Water Repellent is a modified siloxane based product specifically designed for chimneys to penetrate deeply in to most masonry and concrete pores. Unlike acrylics, silicones, and other waterproofing sealers that form a film on the surface and trap water vapors, ChimneyRx masonry waterproofing products allow deep penetration of the active ingredients of up to 1/4 inch or more. As a result, the special siloxanes in ChimneyRx Masonry Chimney Water Repellent react to form strong chemical bonds beneath a treated surface. These bonds allow the product to become a physical part of the structure and provide long-lasting water repellent protection without altering the appearance of the brick.

    ChimneyRx Masonry Chimney Water Repellent is 100% vapor permeable, which allows the water vapors to escape. This reduces costly chimney repair such as spalling, scaling, deterioration, and freeze-thaw damage that results from trapped moisture when film-forming water sealers are used. The best way to prevent chimney water damage is by using chimney repair products such as ChimneyRx penetrating (non film-forming) water repellents that will allow vapors to pass through.

    • Keep Masonry Looking New
    • Will Not Alter Surface Appearance
