A: The most common problem is the removal of stains from stone surface , which may be on top of surface or impregnating stain. In some cases, it just surface dirt. However, stains come because the stone has a porosity, or the impregnator has not been applied improperly. A properly applied quality sealer will greatly reduce the porosity of the stone and inhibits stains. Not all stone installers are applying sealers.
Q: What to do to avoid this problem?
A: Selecting dense stones is always a good idea. But in nature all natural stone have more or less porosity which will allow stain to penetrate in porosity. So stone installers has to use a sealer.

A: Sealers are of different type depending upon working type of surface and also a base of sealer. Mainly two types of sealers are there as per working property. 1 Surface sealer 2 Impregnating Sealer And as per base there are two type of sealer are there. 1 Water base solvent Base.
Q: Which sealer i have to use?
A: Impregnating Sealer should be use as it will penetrate and become a part of stone so there is no chance to peel of a sealer film.
