Classic Marble Restoration, Inc. specializes not only in marble polishing and restoration, but also stain prevention. Sealing your natural stone and terrazzo will help to prevent staining and discolorations from becoming a permanent part of your stone surface.
The first rule in sealing your natural stone is “never use a topical sealer.” This is a common mistake that we see DIY (do it yourself) homeowners make. They go to Home Depot or other “big box” stores and ask anyone with a name tag for assistance. Although some employees know better, others just point you in the direction of the area that sells products to “meet your needs.”
A lot of the sealers sold in these environments and scenarios are designed for tile and non-porous materials. They contain topical epoxies, acrylics, and waxes which are all very harmful for natural stone.
Natural Stone, which includes marble, travertine, limestone, granite, onyx, quartzite, and is even part of some terrazzo contain pores. These pores are the openings in the stone that allow it to “breathe” and release moisture and gas. If your natural stone does not breathe it will eventually deteriorate and stain. Topical Sealers do not allow natural stone to “breathe.”
Impregnating Sealers are specifically designed for Natural Stone. These types of products will absorb into the stone and not clog the pores. They do not reside on the surface and do not absorb contaminants like some topicals do, mainly waxes. When the stone’s pores are coated with an impregnating sealer they make the stone resistant to oil and water-based stains. This allows you to wipe and clean certain liquids from the surface of the stone without leaving behind discolorations. However, certain liquids such as alcohol and citrus fruit juices contact acids that will create “etch” marks, regardless of the best impregnating sealer on the market. Etch marks do not have color, but are chemical burns on the surface of the stone that appear as “dull spots” and may even be rough to-the-touch sometimes. In most cases, etch marks can be removed by honing or even just by polishing the stone.
Granite and Quartzite are denser natural stones. Although they are harder and less absorbent than the previously mentioned stone – they should be sealed too.
Classic Marble Restoration, Inc. utilizes high-quality impregnating sealers that are specific to the type of stone that needs application. If your stone is porous – it should be sealed. It’s that simple.
