Cultural stone is a material used by many people at present. Mostly used for exterior wall decoration or indoor background wall decoration, but some people still don't like it. What is the reason? Because the so-called cultural stones are generally made of natural stone tailings, that is to say, they do not necessarily match in tone. Second, the cultural stone is divided into thickness, and the effect of thinness is not obvious. Too thick to pass through the security barrier on the wall. Third, the stone surface is mostly uneven and easy to cut people. Fourth, the joints between stones are not handled well. To sum up the above problems, it is generally only used in a large area.
