Brick can come in a variety of forms and be used in many applications of construction. Whether a form of brick is used in house construction be it a retaining wall, chimney, pillars, the house itself, etc., it should be sealed to lock out moisture. Penetrating moisture can deteriorate the brick making it brittle. It can also lead to unsightly problems like efflorescence, fading, discoloration, mold, mildew, or algae. Sealing the brick with a quality brick sealer will provide a protective coat of armor against these contaminants and help to prolong the longevity of the brick.
Prior to sealing brick of any type the surface first needs to be cleaned. Use a quality brick cleaner to breakup dirt and grime. Using a pressure washer, clean the area of the bricks including the mortar joints to remove discoloring dirt, mold, mildew, and grime. If the bricks are suffering from salt leakage be sure to use efflorescence cleaner. If you do not have access to a pressure washer, use brick cleaner and warm water and scrub the brick with a stiff brush. After cleaning allow the brick to dry for a day or two.
Best Sealer for Brick Walls to Prevent Water Penetration
Bricks are used for many aspects of construction. They are considered as one of the strongest and longest lasting building materials in history. Bricks can be made of clay, concrete, stone, ceramic, or lime and sand. Like other exterior building materials, a brick wall should be sealed to slow the effects of weathering. When moisture is allowed to penetrate the brick, the damaging effects can cause cracking, breaking, crumbling, and efflorescence problems.
One of the most potentially problematic areas of a home can be the chimney. Chimneys are more prone to water damage because they extend above the roof line making them more vulnerable. Water damage is a 1 billion dollar per year problem and many water related issues like efflorescence, freeze/thaw damage, deterioration, and structural failure start with the chimney.
One of the most problematic areas of a home is the chimney. Water and moisture can cause scaling, deterioration, spalling, water intrusion in the home, and freeze/thaw damage. Waterproofing and sealing a chimney can be vital to its structural integrity.
Before sealing a brick chimney, clean the surface with a brick cleaner to remove all curing compounds or visible stains such as mold, mildew, efflorescence, or rust. The chimney should be clean and free of dirt, oil, dust and any unwanted contaminants. For severe mold, mildew, fungus, or algae use a bleach solution.
When dealing with a chimney, it is important to practice safety and never get on a ladder or roof without the proper knowledge and experience. Wear chemical resistant gloves and safety glasses when handling cleaning solutions.
