DEFY 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, DEFY 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 DEFY 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.
Breathable Masonry Waterproofing Prevents Chimney Water
Damage
Moisture, from
either internal or external sources, is usually present in brick,
masonry, and concrete. A DEFY Masonry Chimney Water Repellent
treatment 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 DEFY penetrating (non film-forming) water
repellents that will allow vapors to pass through.
