First thing you should know is what kind of stone you’re dealing with.
Natural stone, which is siliceous stone or calcareous stone, is classified into two general categories according to its composition. Knowing the difference is essential when choosing the right products and techniques for the cleaning.Do you want to learn more? Visit Canyone in the Nevada Desert
Siliceous stone consists mostly of silica or quartz-like crystals. With moderate acidic cleaning agents it will generally be very effective and fairly easy to clean. The various siliceous stone types include granite, slate, sandstone, quartzite, brownstone, and bluestone.
Calcareous stone is mainly composed of calcium carbonate. It is not appropriate for the use of acidic cleaning agents, which often requires different types of cleaning than silica relative. A variety of calcareous stone types include granite, travertine, calcareous and onyx. If a product works on silica tile, this does not mean that it is ideal for surfaces of calcareous.
How can you tell the difference between the 2 An easy sensitivity test for acids can be done to separate whether a particular stone is calcareous or silica. What’s needed is some 4 oz. Of a 10 percent muriatic acid solution and an eye dropper. Household vinegar and an eyedropper can also be used. Because this test can permanently damage the stone, choose an area that is not often seen or used as a corner under a wardrobe and is reasonably long away from the mortar joint. Apply a few drops of the solution to the surface of the stone over an area about an inch in diameter. If the stone is calcareous, the water begins bubbling violently and/or fizzing. The stone is most likely siliceous, if there is little or no reaction. Clean the area with clean water completely, and wipe it dry. However this test may not be effective when using stone sealers or polishes. If you know a sealer has been used, chip away a small piece of stone and apply the solution to the fractured surface. Proper protection of the head and body is essential when using acid.
A polished stone has a glossy surface reflecting the light and underlining the material’s color and markings. Often this type of finish is used on walls, tops of furniture and floor tiles as well.
A sharp finish is a smooth surface, with very little reflection of light. For locations where heavy traffic is wearing off the polished finish in areas such as floors and thresholds, an honed finish is used. Furniture and other surfaces may also have a sharp finish.
