Bricks are one of the oldest known building materials dating back to 7000BC where they were first found in the middle east. Today bricks are one of the most common building materials used on residential homes, commercial buildings and decorative surfaces. Bricks are composed of a mixture of water, clay and shale. Today bricks are usually artificially hardened by burning them and putting them in kilns somewhere between 1000 and 1200 degrees F.
When purchasing a home, one of the main attractions of the home is the appearance. If a house has no curb appeal, it is going to be harder to market and sell. Bricks are known to be one of the most appealing features to the exterior of a house. To keep the bricks in excellent condition they need to be protected. In order to protect bricks from harsh elements it is best to seal them with a silane/siloxane blended sealer like Ghostshield Siloxa-Tek 8500. This sealer will not only protect the bricks from organic growth and efflorescence but it will reduce water and moisture intrustion. Since water can easily penetrate brick, Siloxa-Tek 8500 would be your best option especially if you are looking for a natural finish. (The sealer will arrive as a milky white liquid but it will dry clear.)
