Blue Granite Pattern

Basic granite slabs cost between $40 and $60 per square foot. The price jumps up to $75 to $100 per square foot for rare colors, stones, and patterns. Prices vary according to color, which can range from white to gray to green to blue.

Usually, the minimum average size of a granite slab is 105″ x 54″ to 112"x78". Thicknesses can also be 3/4″ or 1-1/4″ . The granite slabs are packed in bundles of approximately 400 to 450 square feet.

Mix a poultice paste of baking soda and water (for oil-based stains), or baking soda and peroxide (for others), until it's as thick as peanut butter. Spread the mixture over the spot, cover it with plastic wrap that you've poked a few holes in, and secure it with masking tape. Let the poultice paste stand for 24 hours.

While bleach is a great disinfectant, it can dull the finish of your granite and in some cases even change its color. There are other, safer, ways to disinfect your stone, so avoid bleach and any products that contain it when cleaning your granite.
