Seal right the first time!
Sealers are a "first line of defense" providing some time to clean-up spills thereby minimizing their negative effects. We formally test the products of the most prominent sealer manufacturers determining their quality and effectiveness. Sealers come in two forms:
1. Impregnating/Penetrating Sealers:
These invisible sealers are absorbed into the surfaces' pores and permit vapor transmission. They do not "coat" the surface. we use a combination of sealers depending upon the stone or material and its location. These sealers help to repel, for a time, most liquids like water, oil, or dirt and other contaminants. They reduce the negative effects of contaminants, and prolong the health and beauty of the material. Sealers do not repel all caustic liquids nor prevent eventual absorption.
2. Topical Coatings (film-forming sealers):
These products are best used for man-made materials. Coatings have film-forming properties that help to resist traffic, the elements and most pollutants. They are best for situations in which one wants to create a customized finish or end product through adding color, sheen and texture.
We discourage employing them on natural stone due a tendency to some that easily scratch, flake, and yellow. This also applies to the cheaper polishing products that utilize waxes and acids like crystallizers. Even though the stone is superficially protected, some coatings require regular stripping and reapplication.
