Problems solved by technology

However, the cost and process of exterior wall bricks are relatively high for the first time, and the requirements for pasting are high, and the construction is difficult. If the construction technology is not too hard, it is easy to cause falling off and hurting people. Waterproof materials must also be used to solve the waterproof problem; water seepage of exterior wall bricks The problem is that once water seepage occurs on the exterior wall of facing bricks, it is difficult to find where the water seepage is, which will bring a lot of trouble to future maintenance; compared with the cost and safety of exterior wall bricks, and building exterior wall decoration Materials must take into account the dual functions of protecting the wall and beautifying the wall. The advantages of exterior wall coatings are obvious. It is rich in color, easy to construct, easy to maintain and update, light in weight, non-toxic and tasteless, and its quality can meet the requirements of protection and decoration. Requirements, is gradually becoming the leading building decoration materials
[0003] Due to the implementation of the new standard, the performance requirements of exterior wall coatings are even higher. This standard adds water permeability indicators to the performance of topcoat coatings. However, the requirements for water permeability indicators directly lead to an increase in the cost of economical exterior wall coatings. Coatings manufacturers and engineers are under tremendous pressure
