 A-T Brick Chimney Sealer is a water-based formula of siloxane and alkylaoxysilane.  It penetrates into the brick top form a water repellent barrier against wind driven rains.  After penetrating, it forms an invisible barrier.  The microscopic pores are filled below the surface.  This forms a hydrophobic barrier that last for years.

Why a Breathable Brick Sealer

Most of the water that gets into a brick chimney comes from the exterior face of the brick.  However, water also comes from inside the house.  In fact, combustion from fireplaces and furnaces give off water vapor.  This water vapor will enter the brick from the interior face of the brick.  It must get out or the water will collect inside the brick. And if it freezes, the water will expand and cause spalling and flaking damage to the brick and mortar.

Most brick sealers are made of silicone or are wax based.  These form a layer of protection that is not breathable.  Thus trapping the water vapor inside the brick.

A-T Brick Chimney Sealer is a penetrating sealer that is 100% breathable.  Water vapor from the interior of the building will escape to the surrounding air, increasing your protection.
