Stucco is another porous concrete material similar to brick. Therefore, it has the same basic composition, qualities, and characteristics of brick, which for our purposes are mostly that the two types of concrete are more delicate and decorative. Despite the differences, stucco is similar to concrete and calls for the same type of concrete sealers to be used to protect stucco slabs and facades.

Many stucco facades are attached to homes that are near the ocean or other large salt bodies of water. These bodies of water pose a debilitating double threat: the water from the storms can seep into the stucco, eating away at the its strength and structural integrity, and the salt from the breezes can similarly corrode the material. Therefore, it is almost imperative that you use a concrete sealer for your stucco if you live near a body of salt water.

The best option to seal stucco is the Siloxa-Tek 8510 (solvent based) or the Siloxa-Tek 8500 (water based). These sealers use particles of silane and siloxane to penetrate into the stucco while simultaneously bonding to the surface of the substrate to create a hydrophobic barrier to lock out water and salt.
