Stain Removal

Most natural stones such as marble, travertine and limestone stain because they are a porous material. If a colored substance spills onto these surfaces and is left untreated for some time, the substance will most likely penetrate into the surface and become imbedded.

Other materials such as a honed or textured surface are typically more porous and are more prone to absorbing liquids. The longer the spilled substance remains on the surface, the more time it will have to penetrate and the more difficult it will be to correct. Acidic and alkaline solutions might react with the natural minerals within a stone and can cause discoloration or a stain from within the stone itself. Hard water is also known to cause staining on natural stone due to minerals such as magnesium and calcium.

The stain removal process first involves identifying what caused the stain. Stains are usually caused by organic or inorganic substances. Once the stain is identified it is crucial to clean the area of any other surrounding contaminates. Once the area is cleaned and prepped, a poultice paste is applied and covered with plastic for 24 hrs. After the 24 hr period is complete, a technician will return and revisit the stained area to remove the plastic and the poultice from the stained area.

It is important to realize that some stains could be permanant while other might require more than 1 poultice paste application. Sealing treatments for your natural stone are known to minimize the stones pourosity and are crusial in preventing future stains.
