Brick is especially delicate, and the only real option for sealing a brick exterior (or even a brick chimney, if that is the only brick surface your home features) is a silane/siloxane type of sealer. The Siloxa-Tek 8510 is the only real choice for anyone wanting comprehensive protection that is long-lasting. While other products may give the same level of protection, they will not last as long.
The Siloxa-Tek 8510 is a penetrating silane/siloxane solution, specifically designed for use on brick and masonry substrates. The way the sealer is designed, it is better suited to being applied on vertical surfaces. The sealer is a clear, solvent based product that provides a translucent exterior that will not mar the visual appeal of your brick exterior. The sealer will create a hydrophobic barrier, locking out water and salts, as well as any other external threats, ensuring that your brick does not crack, crumble, and corrode over time, as unprotected brick is widely known to do.
