The quality of natural stones highly depend on the quality of blocks from which tiles and slabs are produced. That means, with varying quality for the blocks, varying quality for slabs and tiles are expected. It is clear that all materials included in any block are not from the high quality. In other words, out of 100 %, only 20% of the block are highest quality, 30% are standard quality materials and the rest 50 % are commercial grade quality. In fact, the percent of commercial grade quality materials highly affect the price of the stone. Generally speaking, these commercial grade qualities can be classified as fissure, pitting and stain.
Fissures and Pitting
During the process of stone formations as the result of merging two separate flow of liquid hot magma into one single flow, fissure is formed. So, it is a natural flaw and no one can do anything about it. Therefore, during the whole process including producing slab and tiles, these natural junctions and line of separation can be seen.
Pitting on the other hand, is a tiny space seen on the surface of natural stones especially white kinds like Carrara Bianco and Statuario marble; it is a natural property for the natural stones and cannot be removed.
A stain is a discoloration, but not vice versa!
Stain is a dark chip on the surface of the stone. There is not a single exception to this rule. This discoloration of the stone can provide no solution for its removal.
There are different kinds of staining that forms on the surface of natural stones. Although there are different kinds of saint is formed on the surface of stones; some are treatable, some are not. Some spills penetrate in the pores can be resolved using surface cleaner
Similarly, with natural stone, there are discolorations that may have been caused by chemical damage. With chemical damage, the surface of the stone is actually physically altered
One of the other problems can cause humidity on the surface of the stone after installing over times is rusting. In fact, rusting is another kind of stain that is likely to occur on natural-stone tiles and slabs because of their chemical composition and molecular structure. It usually happens on the natural stones due to some chemical process as the result iron deposit existing within stone. It can happen on floors, countertops, and surrounds or any other places made of natural stones
A list of recommendations to avoid rusting on the surface of the stones can be:
- Avoid the surface to water, for some surface on which water avoidance is virtually is impossible, granite sealer is the best option.
- Avoid using acidic cleaners and substance as well as metallic or steel wool pads to clean the surfaces
- Use granite cleaner and soft nylon brush or gentle scrubbing pad
- For stubborn rusty stain , Spray or pour 3 or 4 percent hydrogen peroxide on the stained area, then add granite cleaning pad to agitate it more. Let it sit for 24 hours, then rinse it with water
