Defy Brick Water Repellent 1 Gallon

DEFY Water Repellent for Vertical Brick is a modified siloxane based product designed to penetrate deeply in to most masonry and concrete pores. This masonry waterproofing product allows deep penetration of its active ingredient of up to 1/4 inch or more.

The special siloxanes in DEFY Water Repellent for Brick 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. DEFY Water Repellent for Brick treatment is 100% vapor permeable, which allows the water moisture to escape. This reduces costly chimney repair such as spalling, scaling, deterioration, and freeze-thaw damage that results from trapped moisture when clear coatings and water sealers are used for waterproofing brick.

Applies with pump sprayer.
