There are a number of causes for yellowing marble—and a number of possible cures. The most common culprit for white marble turning yellow is iron, which can be found in many natural stones. When exposed to water, acids or bleach, the iron in the stone will begin to oxidize and turn it yellow. Other causes may include wear and tear, improper cleaning, wax buildup, and crystalization.
Spalling, cracks, breaks, crumbling, and other problems usually are not the result of some problem with the stone itself, but with the stone's environment. There are many potential causes for stone installation failure, including temperature fluctuations, moisture, installation methods, materials used during installation such as adhesives or mortar, shifting and settling of supporting surfaces, and other factors.
Loose tiles are most often a result of debonding and delamination. Debonding happens when two materials are supposed to stick together, but don't. Delamination happens when layers of laminated material separate. There are numerous reasons why these problems occur. The most common causes are poor substrate preparation, improper mixing of setting materials, improper setting methods, and flooding.
Monument stain removal should be performed with extreme care by a professional stone restoration contractor. Improper stain removal methods can result in damage to the stone. Stain removal methods will depend on the source of the stain, the type of stone, and other factors. There is no one-size-fits-all answer to this question.
