If you have a home constructed from stucco, you are probably wondering what steps you can take to protect it from the elements. Traditional concrete basements, floors, and foundations are obvious candidates for concrete sealers, but what about homes made of stucco? Fortunately, you can use a concrete sealer on stucco, which will function just as effectively as on traditional concrete; however, it is important to choose the right variety of concrete sealer.

The problem lies in the fact that stucco is a more porous concrete material. Being more delicate than traditional concrete, whose small pores dot solid gray facades that we typically associate with concrete in our minds, stucco requires a concrete sealer that offers better protection for more delicate forms of concrete. Stucco itself is similar enough to concrete that the same basic types of concrete sealers can be used.

The best choice in concrete sealer for homes made of stucco is a silane/siloxane sealer. The silane/siloxane sealer uses particles of silane and particles of siloxane to both penetrate within the stucco and to bond to the surface. This dual action creates a hydrophobic barrier that will protect the stucco from water, salts, and other environmental threats to the stuccos visual appeal and structural integrity. The best silane/siloxane offering on the market is the Siloxa-Tek 8500. The Siloxa-Tek 8500 offers the most comprehensive level of protection out of all silane/siloxane sealers, featuring an extended warranty and excellent characteristics of resistance to water and the elements.
