My MB Stone Pro Experience

I was trained by Maurizio Bertoli of MB Stone, what seems like a lifetime ago. The training just started during that four days. Maurizio helped me for many years answering phone calls when I was stuck on a job, or an email regarding how to grow my business. During those years I met Stu Rosen and quickly formed a great relationship with him as well.

I still remember that horrible day when Stu called me to tell me about the accident that took Maurizio from all of us too soon.

Eventually Stu took over the reigns of MB Stone. I was so impressed he consistently honored our mentor while slowly working his imprint on both the training and products.

My sons worked throughout high school and college in my little marble restoration business. My oldest son came to a MB Stone training event, probably one of the last that Maurizio ran. Stu participated in that training in support of Maurizio. My son, Tim, was very young. He came along for the trip and Maurizio invited him to participate. I was a little taken back and nervous watching him grab the big grinder removing lippage!

As I got older, two of my sons graduated from college announcing they wanted to keep my company going after I retired. I had no idea they each were even considering that because they are both so smart they could simply do anything they wanted to. I will admit, I was so proud they would choose my meager company, creating a legacy for the last business years of my old life.

They started attending the new Stu version classes of MB Stone and started calling Stu when they needed help.

Tim has restored over 6,000 floors by the tender age of 25. Kyle has restored over 2,000 tops and 3,000 showers. Kyle lifts weights 6 days a week just to make sure he has the physical stamina to do such hard work.

We buy all of our equipment and supplies from MB Stone. Once in while they tell us about a product we should use that they don’t carry and I am forced to go elsewhere. But we would never consider buying anything elsewhere. The valuable help we derive from their formal training and helpful phone support make it a no-brainer for us. With the solid base of them knowing exactly what we have in our arsenal, and how we were trained to use it all in harmony, they can offer very insightful help.

So if you are new to the natural stone restoration business or a seasoned veteran looking for a great and helpful business partner, Stu Rosen and MB Stone Pro is the right way to go. Go to a training class and listen, try out some equipment, talk with the other attendees and it will change your life. It sure did for me.

What Is The Best Product To Remove Scratches/Etches (And Future Scratches/ Etches) From Marble In Bathroom

Question: I have a project that is only 6 mos old and although it was sealed, it is now etched in many places all over the vanity, the floor also has some etchings—it is mostly from toothpaste I think—and its use won’t stop

The vanity top is nero marquino marble, the floor and walls are “asian calacatta” marble.

 I need advice—

1.    What is best product to remove the scratches /etches (and future scratches/ etches) that I can use with my black and Decker mouse sander (random orbital sander)—this sander has a polishing pad attachment (doing this by hand seems tedious and there are a lot of etch marks)

2.    What is best sealer /protector to protect it from acids and stains after I polish it?

3.    What is best product to clean the marble of soap scum that can also be used to remove soap scum from bathtub—there are many products to remove soap scum but are not recommended on marble-it is impossible to clean the tub and not get it on the marble –so we are stuck. Please help!

Answer: Thank you for contacting us regarding your stone. First I want to explain that no sealer will protect the marble from etching. Sealers are designed to give you time to clean up a spill to protect from staining. An impregnating sealer is absorbed into the stone- it does not sit on top. An etch is actually a chemical reaction between something acidic and the calcite in the marble. Etching is instantaneous.

1) Our MB11 Marble Etch Remover and Polishing Powder is designed for spot treatment of etches. It is designed to work on lighter, polished marbles. If the nero marquino vanity is a more black marble, the MB11 will not work well on that one (we recommend contacting a Stone Restoration Professional to restore black marbles). For the asian calacutta, MB-11 work perfectly and all the directions are on the container. Basically you will place a couple of pinches of the powder on the etch, mist it with water, and then using even your hand and cloth, buff in circles (adding pressure as you go) until all of the powder is gone and the surface has been restored to a nice shine.

2) The impregnating sealer we recommend is the MB24 Barrier. It is water based and oleophobic and hydrophobic- meaning it resists oil and water which will allow you time to clean up any spills before it can be absorbed. Again, nothing short of encasing the marble will protect it from etching.

3) MB3 is the product we have for soap film. It is a concentrated product and is very effective and is safe for all natural stones. We also offer a Bath and Shower Kit that includes this product as well as MB5 (daily cleaner) and MB9 (mildew remover) that might be useful for you to care for the bath as all of these are safe for stone.
