YEP! I removed an acrylic 'coating' on a mixed marble and granite floor yesterday that was applied by none other than the 14 year old SON!! It was "his" project. He applied a coat about every two weeks for a year before they found me, now it is "my" project. Floor stripper worked well. He will never touch the floor again.

	Marble MARBLE: CHARACTERISTICS This standard includes general information on the characteristics and common uses of marble and identifies typical problems associated with the material. INTRODUCTION Marble is an extremely hard, metamorphic stone composed of calcite (CaCO3). It is formed as a result of the recrystallization of limestone under the intense pressure and heat of geologic processes. The effect of this process is the creation of a stone with a very tight crystalline structure and small but definite porosity. Because of its structure, marble can take a very high polish and is a very popular decorative stone for architectural and sculptural uses. The limited porosity of marble, especially polished marble, makes it less vulnerable to the leaching effects of water. Calcium carbonate, however, of which marble is composed, is highly susceptible to attack by acidic agents. Marble is readily dissolved by acids, even very dilute acids, however the actual results of acidic exposure will vary with the nature of the acid. Chlorides, nitrates, sulfates and other chemical compounds react differently with marble and produce various by-products, which have a wide range of solubility and impact on the durability of marble. For this reason, it is always important to determine the exact type of pollutants causing marble deterioration. Marble itself can be of two types, one composed of calcite and the other of dolomite. Dolomitic marble is much more resistant to acid attack than calcite marble. The color of marble ranges from the brilliant white of calcite to black, including blue-gray, red, yellow and green, depending upon the mineral composition. TYPICAL USES Marble has many decorative and structural uses. It is used for outdoor sculpture as well as for sculpture bases; in architecture it is used in exterior walls and veneers, flooring, decorative features, stairways and walkways. The way in which the stone is used may be a factor in limiting or controlling the severity of exposure. The use or function of the marble may also affect the feasibility of applying certain treatments, but type of use is not the primary factor in the major types of deterioration and damage to which marble is susceptible.

That comment was actually an inside "joke" to someone on this thread.

Just reviving this thread.. When I was in Vegas at the Bally Casino, I noticed they wax their natural stone floors. I figure cause it is to save time on labor and cost. and what the hell, they have money to buy new marble floors once they kill the stone.

I have come acorss finish/wax on marble too. Used razors to scrape in the beginning, so diamonds dont float. I know that there are strippers, but they must be chosen carefully, in case they might have chemicals in them which can cause more damage before restoration work is done. I have used Buckeye Jaugernaut to strip. But, are there any other floor strippers that are safe which you anyone can recommend?

Mahalo,

Yes there are many you can use. I use chemicals over a scraper any day.
All you have to do is size up the conditions. ID your coating to be removed. Find out what the limitations are as far as vapors are concerned. Be sure the chemical will dissolve the coating 100%. Vac it up and proceed with a milder solvent or a lite 2nd removal process and you are ready to grind etc. Be sure when you use solvents you are on 100% stone not resin stone mix.

A good solvent base floor finish stripper for stuff like carpet glue and a good epoxy thinner works quite well on the harder type coatings. This is only to be used in controlled areas with active venting.

I find it very easy to do if you are use to being able to control your environment.
I do a lot of commercial work and this is how we do it. I am the trouble shooter so I pick and choose the procedures we use.

	epoxy EPOXY A two part resin with superior adhesion properties used for joining and filling stone. Also used for grouting stone and tile.

Just name something - anything that you can think of and, I assure you, I've seen it applied on a marble foor one time or another!!
I even saw a White Carrara marble floor totaled by the "creative" homeowner because they didn't like the color and try to deep-stain it in blue!!!
(Needless to say, when they called me for the "estimate", I charged them $450.00 only to go there and look at that hopeless mess!!!)

Ciao and good luck,
