APPEARANCE/USE

Q. What makes granite the hardest building stone?
A. Granite is formed by solidification of liquid magma (molten rock) under the pressure of earth's crust. It is composed of Feldspar, Quartz, Mica, and other minerals, making it one of the hardest stones in the world. It has been used for building and decorative purposes for centuries. Granite resists wear-and-tear applications remarkably well, making it ideal for interior or exterior flooring. When used outdoors, granite's mineralogical structure is not influenced by freeze-thaw cycles.

Q. What do the finished surfaces of granite look like?
A. Granite can have four main finishes: polished (shiny), honed (matte), flamed or brushed (textured). The polished and honed surfaces are flat and smooth. The flamed and brushed surfaces are flat and textured. The polished surface is shiniest, while the brushed surface reflects the least amount of light. The back and sides have a sawn finish.

Q. What applications are recommended for these granite finishes?
A. Granite finishes are suitable for different applications. For example:
· Polished surface – low traffic indoor flooring, wall cladding, counter tops, vanity tops & decorative items
· Honed surface – high traffic indoor/outdoor commercial flooring, wash rooms, side walks.
· Flamed or Brushed surface – external flooring, decks, pavements, side walks, curb stones, garden benches

Q. Why is granite an excellent material for kitchen countertops?
A. Next to diamond, sapphire, and ruby, granite is the hardest natural product on earth. Once polished, natural granite will maintain its high gloss virtually forever. Normal use of kitchen knives, cutlery, and cookware leaves no scratches. Heat has almost no effect on natural granite, making it much safer than synthetic surfaces with polyesters and resins. Pots and pans heated to 900 degrees Fahrenheit will not dull natural granite's lustrous finish, but the use of trivets is recommended to keep your granite counter clean.

Q. Can I use granite tile for bathroom flooring?
A. Like any other smooth surface floor, the polished surface of a granite bathroom floor can be slippery if it gets a lot of water and is walked on with improper footwear. A honed granite surface is therefore recommended for bathrooms.

Q. Can I use granite tile for counter tops?
A. Granite tiles can be used for a counter top surface. It is recommended to use a 3/4"sub-board with waterproof membrane to support the tiles. It is also essential to seal the tiles after installation to avoid staining.

Q. Can I use granite tiles on shower walls?
A. Granite tiles can be used on shower walls. It is recommended to use cement backer board or hardy board with a waterproof membrane to avoid transfer of moisture. It is also recommended to seal the granite after installation to avoid water absorption and mildew formation.

INSTALLATION
Q. Can granite tile be butted or do I need to leave a grout line?
A. Granite tile floors appear the best when the tiles are butted. However, it is important to make sure the tiles are matched before setting on thinset.

Q. Does L & Z Stone do granite tile installation?

Q. How much does granite weigh?
A. Granite tiles and slabs come in different thicknesses. The weight per square foot for each thickness is as follows:
· 3/8"(10mm) thick tile: 5.5 lbs sq. ft.
· 1/2"(12mm) thick tile: 6.5 lbs. sq. ft.
· 3/4"(20mm) thick slab: 12.8 lbs. sq. ft.
· 1 1/4"(30mm) thick slab: 18 lbs sq. ft.

QUALITY
Q. Is your granite real and why is it so inexpensive?
A. All the granite products sold by L & Z Stone are genuine granite, produced from the natural rock and are first quality. We are able to sell at such low prices because we ship directly from the production site, in addition to cost reductions owing to our huge volumes in shipping.

Q. Is your granite Kerosene cut?
A. No, it is not. L & Z Stone ensures that all its granites are cut by using water as coolant and gives a lifetime guarantee of the quality. Some manufacturers use petroleum by-products in the coolant to aid the cutting process and reduce processing costs. The granite is later soaked in water and washed to remove the chemical smell, but the damage is done the moment the chemical comes into contact with the ferric content in the stone. Within a couple of years, rust marks will appear.

Q. How do I know L & Z Stone granite is high quality?
A. L & Z Stone supplies only first quality material. The quality of the material is determined by measuring different parameters of a granite product through the entire production process:
· Mining – L & Z Stone’s granites are mined utilizing modern methods. Some mines still use dynamite or blasting methods to reduce cost, but this also damages the granite. The shock wave created by the blast will cause invisible hairline cracks which will result in the stone cracking at some later time.
· Cutting – L & Z Stone’s granites are cut by using water as coolant to ensure a lifetime guarantee on the quality of the product.
· Dimensions – Product dimensions are controlled within the stipulated limits in ASTM standards. Tiles are calibrated to ensure their thickness is uniform. Gauging is done to ensure the tiles are square. Beveling is done to produce a smooth edge on the tiles
· Inspection: Inspection is done at different stages of the manufacturing process and the products are segregated for unusual patches, major color variation, cracks, dimensions, surface finish, and other quality issues. They are then categorized as first, second, and commercial quality. L & Z Stone supplies only first quality material.

Q. What do I need to consider when buying marble or granite?
A. Because it is a natural stone, marble -and more recently granite- has been blessed with a remarkable natural beauty that has captivated humans throughout the ages. Inherent in such natural products is a certain lack of predictability that sophisticated architects and designers celebrate. Consumers who are less acquainted with the material expect the marble ordered to be identical to the picture or sample they were shown. Although sample stones are intended to be representative of the quarry’s product, the material quarried at one time may differ slightly in color and veining from the sample. Moreover, even a single marble or granite slab will possess a certain amount of color variation from one end to the other. Interior designers and architects have come to view this tendency of natural stone as an advantage. Slight irregularities can be pleasing, introducing an element of the natural into human-designed spaces, whether residential or commercial.

Q. What’s the difference between marble and granite?
A. Although both are stones and both are quarried from the earth, granite and marble (and marble’s relatives – limestone, onyx and travertine) are very different from each other. Granite is formed deep in the earth’s mantle at extremely high temperatures, and is a very hard, resistant stone made of crystallized minerals. The marble family – limestone, travertine, marble, onyx – starts out as sediment – animal skeletons and shells, plant matter, silt – at the bottom of bodies of water. After millions of years this solidifies (lithifies) into stone. Because its main component is calcium, it can be affected by acids such as vinegar and citrus beverages.

Q. Is it necessary to seal stone?
A. Since mineral surfaces are quite porous they absorb liquids, which may result in discoloring and staining. Although there are many commercial grade products available on the market which may bring the stone to its to its original luster, taking simple precautions and regular maintenance can save a lot of trouble and cost. All marble and granite tops are sealed immediately after they are installed. The impregnating substance penetrates the stone clogging most of its pores making its quite impervious to alcohol, juices, soft drinks, cosmetics, cleaners, coffee, food and even oil. With course of time, depending on how heavily the tops are used, the sealer gets washed out. The clear indication of this happening would be the fact that the liquids are easily absorbed into the stone leaving temporary (if promptly wiped off) stains. You should seal your marble every six months and your granite every year, at least.

Q. What is the best way to clean marble and other stones?
A. The old rule of thumb is never to use anything you wouldn’t use on your hands. Never use powdered cleansers or abrasive pads to clean your stone. Even "soft scrub" type cleaners contain pumice, which is powdered volcanic stone, and might damage your stone countertops or floors. Never use any product which is acidic; this includes substances like ammonia or many common liquid cleaners such as Windex. You should always use sealers and cleaning products designed specifically for natural stone.
