Masonry Sealers

Masonry Sealer is a penetrating polyester polymer and water-based polyurethane used to seal and waterproof all types of concrete slabs, walkways, driveways, brick and block walls, stucco and other types of cement such as ferro-cement, flying cement and shot-crete. It also prepares the surface for finish coatings

A masonry sealer is very different from clear wood sealers, wood stains or common house paints. All masonry components have an alkaline PH, this is opposite of wood which is slightly acidic. A high PH isn’t tolerated very well by normal house paints or wood stains.

The primary goal of a masonry sealer is to stop liquid water from entering a hard masonry surface but allow any acuminated water vapor to escape before damage occurs.
Water can readily damage most masonry surfaces after a few years of exposure. In both its liquid or vapor form, water can cause cracking and change the alkaline nature, which will drastically weaken any masonry material.

Water damage is very hard to fix once it has happened. Using an appropriate masonry sealer can prevent much of this damage before it occurs and is cheaper than repairs.
