FLOORS
Q. My polished marble floors seem really dull or worn in areas. Is this something that can be fixed? Can I fix it myself?

A. Contrary to popular belief, marble floors often are not very durable. Regular foot traffic and pivotal points can begin to “sand” away the even sheen from the original surface. The good news is that it can be restored. However, it will require professional services. By using abrasive diamond disc on the bottom of floor machines, we can first remove the existing wear with low diamond grits. Then we follow a sequential pattern to properly “close” the stone back up preparing it for a final polish. In most cases, a slightly acidic polish is used that further closes the pores of the stone’s surface allowing maximum reflection. Once a surface is restored, follow our Care & Maintenance guide to help you choose the right process and products to maximize the life of your surface. Marble Renewal also offers custom Maintenance Agreements to help tailor a program that will fit your needs and budget.

Q. My polished marble has spots and rings in it that I cannot get clean. Is it stained and is there something I can do about it?

A. Almost all of the time, the answer is no, it is not stained. The surface has been etched. An etch is when the fine factory finish has been compromised by any type of acid based product. This could be almost anything, such as carbonated sodas, hygiene products, alcohol and the list goes on and on. When any mild acid contacts the surface of marble, it creates a chemical reaction and opens up the pores of the surface. The larger the pores, the less light is able to reflect off the surface. Often, there is little an untrained person can do.

SHOWERS/ EXTERIOR APPLICATIONS
Q. My grout lines and surface seem to have a white, chalky material that I cannot get cleaned. What is it and what can I do about it?

A. What you have just described is referred to as efflorescence. This is where moisture “leaches” through the surface leaving mineral deposits, causing a white, chalky appearance. Often, using aggressive cleaners and a stiff nylon scrub brush can do the trick. However, it does often require skilled labor and additional equipment to completely remove it. Sealing the surface can help prevent it, or at least slow it down but it can reoccur. Efflorescence is most commonly found in showers and exterior stone applications such as slate.

SHOWERS
Q. The grout in my shower or floors are cracking or breaking out around the edges. Why is this happening and what is the long term solution for it?

A. Many times installers will grout all areas of showers and floors, including the 90 degree transitions such as from a floor to a wall. Because marble and any natural stone surface is very rigid, it does not flex very much. In a 90 degree transition, there is a need for flexibility. A rigid grout will crack. We recommend replacing grout with caulk in these areas.

Q. My shower walls are dull. The areas from about shoulder height down seem to have a residue or film on them. Why is this, and what can I do to fix it?

A. Even a slight mineral content in your shower water can slowly etch and dull the surface over time. Showers, above all other natural stone application, require the most care. Diamond restoration is usually the only way to fully return the surface to its original appearance. However, if you will properly maintain the surface, you can slow down the damage. It is also important to squeegee the walls dry after the last person has showered each day. We offer a variety of service options specifically geared towards showers.

VANITIES
Q. My marble sink or shower has a spider web crack around the drain. Is there something that can be done about it?

A. What you have just described is a very common question. Unfortunately, you have just described man-made marble, or cultured marble. Marble Renewal is not qualified in the area of restoring cultured marble.

Q. My vanities are getting dull and look very “spotty”. It is mostly around the sink bowl. What has caused this, and how can it be fixed without replacing the entire top?

A. Vanities get the most use around the sink area. Moving items around on the surface can scratch and dull it in those areas. Also, hygiene products like toothpaste and hairspray all have an acidic content too them. This will etch the surface leaving rings or spots that look like stains. Generally, they go away when wet and return once the surface is dry. Lighter etches may be removed with professional powder polishing, but in many cases, diamond restoration is necessary.
