Natural Stone Porous Materials Protection Cleaning D.I.Y.

What sealers don’t do

Impregnating sealers can offer protection, but not against acid etching caused by materials such as citrus fruits.

With the protection impregnating sealers can offer, as well as the way they make surface cleaning that much easier, it can be easy to assume there’s nothing these products can’t do.

However, it’s important to understand exactly what sealers are not capable of before investing in them.

Impregnating sealers penetrate the surface of stone to assist with repelling water and oil, thereby preventing stains and protecting against structural damage that may be caused by liquids.

At the same time, you should remember that impregnating sealers do not make surfaces impervious to staining. Given enough time or pressure, liquids can still penetrate the surface of the treated material. Sealers provide you with the time you need to wipe up spills, but it remains vital to take care of any liquids in a timely manner.

Your treated surface will also need to contend with the wear and tear that comes with time and use. Impregnators do not provide a physical barrier, so scuff marks or dirt being ground into the surface remain a threat.

Finally, impregnating sealers cannot stop acid etching. Materials like marble, limestone, travertine and onyx all contain calcite, a form of calcium. This makes them more vulnerable to acids, even those found in common household items like juice, cola and wine.

Sometimes, even rain can contain trace amounts of acid, leading to problems for calcareous materials used outside.

Even with that said, there’s no denying the surface protection benefits sealers can provide. In addition to helping prevent stains, you can count on your Dry-Treat sealer to assist with protection from efflorescence, freeze-thaw damage, spalling and picture framing.

Just remember going in that while sealers can be essential for surface protection, they are not a cure-all for every risk that threatens your stone.
