1. From the point of view of environmental protection, using acid in the cleaning process of imitation granite will pollute the atmosphere. What needs special attention is that once the brick exterior wall appears seepage, it is difficult to find the location of seepage, and its maintenance is very troublesome.
2. Imitation granite has high one-time investment cost, high pasting requirements and difficult construction. If the construction technology is not too hard, it is easy to cause people to fall off, so waterproof materials must be used to solve the waterproof problem.
