Caring For Your Residential Limestone
Available in a variety of shades of light brown, beige, and yellow very few natural stones provide the elegance and rich appearance of limestone. The most common surface finish for limestone is matte, making it an excellent choice where moisture may be present, as the matte finish provides for a non-slip surface.
As with granite and marble, it is important when purchasing your limestone tiles to pay attention to the lot numbers. Any specific lot number means that the individual limestone tiles were cut from the same block of limestone and should provide a color and grain match. Always remember that one of the things that makes any natural stone floor rich and unique is that no two pieces of natural stone are the same in color or grain. Because of the grain and color differences, it is important that you always buy extra tiles, as any specific lot number may not be available a few days after your original purchase. If you are installing a basic grid pattern, it is recommended that you purchase at least 10% more tile than the square footage calculation would indicate. For a diamond pattern, the recommendation is 20% more than the square footage calculation.
Of course, nothing is ever perfect. With all the positive attributes of limestone, there is one negative. Limestone is a very porous material and even if heavily sealed with a penetrating sealer it should not be used in kitchens or full bathrooms – bathrooms with showers or tubs. Building codes in many areas prohibit the use of limestone tile in restaurant kitchens.
