Help with granite seam!

If it is a black granite, the stone will not ecth. It sounds like the excess sealer was left on the surface. The contractor should have pick the correct sealer for the job and apply it correctly. This a nother reason why there is a need for post installation service.

	sealer Impregnation: This is commonly known as sealers. This is the first stage in preserving and maintaining your investment. This stage should occur ever six to eight months. There are three types of impregnation (solvent, water, silicone based), regardless to brand. This will stop most water base stains from occurring. It also will stop the stone from been damage beyond repair.

I thought that black granites need not be sealed because of their extreme density?

But hey, if you think that they NEED to be then pour it on, boys.

I hear of these problems eight times a day because fab-shops and salesmen think that they\\\'re doing the customer a favor when in reality (remember? That\\\'s the here and now) you are causing your clients grief and ultimately pi$sing yourselves off in the process by having to waste a day making the trip out to the disgruntled client to work off your mistake FOR FREE! I\\\'m sure that\\\'ll make them buy more stone from you... Or anyone else for that matter, including ME!

I could be wrong though... I\\\'m new and dont know jack-all... Speaking of Jack... Does anyone know him?[/u]

All stone will absorb liquid to a degree, some less than others. I have seen more and more stone that was doctored to look like get black granite. As long as a stone can be doctored it can stain. As a stone restoration guy, I determine what needs to be seal and with what. this will depend on the stone and its' application, the customer life style and cleaning habits also plays a small part in my decision. I will never make a blanket statement and claim that one type of stone does not need to be seal.

P.S I do know Jack, would you like for me to tell him you are looking for him.

So Jo, whenever I get this new black top, have them seal it or not?

If Black granite takes in dyes and Ager - it will take in sealer. There is no such thing as a natural stone that is not pourus to some degree. Even that engineered or quarts stuff has some pourosity to it. I have a piece of quartzite in my shop that has stained by rusty water.

Lady, just call the local consumer protection dept. Let them do battle for you. If you contact the Marble Institute of America they may be able to get you in touch with a consultant to figure it out and make a recomendation to solve your problem. Only people who have seen the granite in person can figure out what the actual issue is. Your contractor is obviously going to get as much as he can out of you. Next time stay away from tile guys when purchasing granite. Go to a professional. I am sure you thought you got a great deal when buying the pre-fab.

	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.

Only people who have seen the granite in person can figure out what the actual issue is, and if should be seal or not.
