Response to white pollution
The dry hanging construction method can effectively avoid the problem of whitening, but considering the high cost of stone dry hanging, it is mainly used for the external walls of good buildings. For some small and medium-sized buildings, wet construction of the bottom stone hanging, while the stone to take protective treatment, that is, the back and sides of the stone injected resin, to avoid alkaline cement mortar and stone contact, play an isolating role, stone holes are also closed, effectively prevent water infiltration. In addition, the back of the stone becomes a sticky hairy surface, which can be better combined with cement mortar. When fixing the SLATE, apply the gap at the joint of the two plates evenly with glue, which can improve the tightness and effectively prevent water seepage. Mix the low-alkali cement with the sand in a ratio of 1:3.
Response to rust stain contamination
The board before installation is thoroughly cleaned to remove iron residue and rust, and the resin is injected into the stone for waterproof treatment to prevent the iron minerals inside the stone from being oxidized and leaking to the surface. Try to use dry hanging construction method, use stainless steel accessories. Use protective paint to paint other iron products on the wall and maintain them frequently to prevent rust.
Water stains, wet marks pollution response
As far as possible, the dry hanging construction method is used to waterproof the permeable areas such as balconies and wall bases, giving the stone a new feature of waterproof and antifouling, which can effectively avoid the occurrence of water spots.
Response to frost damage pollution
The stone will lose its surface luster after being damaged by frost damage, and in serious cases it will break after the force impact, resulting in falling accidents. The countermeasures are mainly to inject resin into the stone to make it waterproof, if it is wet construction, it must also take a more comprehensive resin injection of the stone, and the sealant caulking project is also more necessary.
Stone cracking pollution response
The marble to be hung on the exterior wall is pre-cured, and the marble block by block is treated with strengthening agent. The hardness of the stone has been effectively improved, the natural luster of the surface is brighter, the weather resistance is better, and the service life is longer.
Response to bryophyte growth and microbial damage pollution
Water is the main factor for the growth of plants and microorganisms, so to avoid pollution, we must first do a good job of stone drainage measures, followed by the protective agent into the stone interior, the protective agent can not only effectively protect, but also strengthen the stone and increase the bond strength.
