Natural stone is mostly used for laying in the living room, dining room, cabinets, and vanity countertops. The stone floor used outdoors has an international standard thickness of 20mm, and as an indoor floor, the thickness is about 15mm. So, how to choose natural stone as the ground? Next, let's learn about it with the editor of FABULOUS Group.

　　1. Pay attention to the environmental protection of stone. Today, with emphasis on green decoration, natural stone is increasingly reduced in home decoration. The prominent problem is radioactive pollution. Natural stone has different levels of radioactivity, which is particularly harmful to growing children, teenagers and newlyweds. The radioactive substance of natural stone is radium. If you choose natural stone flooring, you should pay attention to choosing one with less radioactive pollution. One is that red, dark red, and green stones are not used, and their radium content generally exceeds the standard; the second is that they must pass radioactivity testing and meet the requirements before they are used.

　　2. Choose the right color and pattern. After you select a design, you can ask the merchant to provide a sample, and check the sample against the sample when you pick up the goods. The color difference is small, and the pattern is roughly the same or similar.

　　3. Pay attention to the processing accuracy of the stone floor. Natural stone flooring is processed by mechanical sawing, planing or grinding and cutting. Finely processed stone should be regular and uniform, so that the stone floor can guarantee the quality of laying. In order to prevent irregularities, consumers can stack two stone floor surfaces when purchasing to see if the specifications around the stone floor are the same, whether the surface is flat, and whether there are defects such as warping and dents.

　　4. Pay attention to the reflectivity of the stone. The reflectance of high-quality decorative stone should be above 95%. Consumers can use glass mirrors as a reference. The reflectance of mirrors is 100%, and the reflectance of first-class stone floors is 75%-95%.
