Description
Technical Field
The invention relates to the technical field of building outer wall decoration processes.
Background
For a long time, the coating quality of the exterior wall coating is poor and the quality guarantee period is short. The inventor learns from the study of paint coating in 1969 that the putty scraping before the finish coating is performed is used for saving the cost of the finish coating material, and the putty (such as pig blood ash and the like) is the material which is most easy to falsely and truthfully, so that the problems of various qualities of the direct putty scraping and the finish coating recoating exist. The fact situation is that the modern industry is developed, a plurality of resin materials for replacing the traditional paint (earth paint) exist, and the old method for saving materials and reducing cost is still adopted in the coating construction; the reality is that the actual coating workers of the coating are all at the 'lower riva' level, and in theory, the existing coating construction technical data does not say the purpose of putty coating. And the painting worker has no skill training before going on duty. Because various exterior wall coatings have coating quality problems of various degrees, the exterior wall coatings are replaced by ceramic tiles with high energy consumption. However, the ceramic tile has the potential safety hazard of hurting people due to falling off when being decorated on a wall, and the waste ceramic tile is not degradable. Although the use of ceramic tiles has many disadvantages, it still occupies the absolute market of exterior wall decoration of buildings, and in recent years, there is still a trend of rising, even under the restrictions of policy. Therefore, an economical and durable exterior wall coating scheme needs to be developed, the process is to strip off the primer coating process from the whole coating process, and is based on the coating purpose that the building is mainly a coated object containing water molecules, so that the primer base of the coating needs to be firmly constructed just by considering the adhesive force of the coating, like coating all metals and plastics. On the basis of the primer coating process, various types of finish paint can obtain durable effect to replace ceramic tile decoration, so that the problem is solved fundamentally, and if the finish paint has quality problems after being used for a plurality of years, the primer is intact as before, and the responsibility is also clear. Therefore, the exterior wall coating primer coating process is used as a basic procedure of exterior wall coating, determines the quality and stability of exterior wall coating construction, and aims to solve the problem that the existing primer coating process and importance are not enough, so that the invention provides the exterior wall coating primer coating process which is an important process for eliminating unstable foundation and dynamic and mountainous shaking.
Disclosure of Invention
In order to overcome the defects, the invention provides a primer coating process of an exterior wall coating, and in the aspect of exterior wall primers, the inventor summarizes a set of construction procedures which are simple and easy to operate, convenient to construct and free from generating environmental pollution dust by combining more than thirty years of practical experience. The primer coating process of the exterior wall coating is a good primer coating scheme for old walls, dry wall walls without cement, sand and ash and dry wall walls with weathering phenomena, reduces the essence of the coating protection function and keeps the ultimate aim of the decorative effect. The problem of inversion of the heavy decorative and light protective powder is solved, and the hidden danger that paint constructors suffer from occupational diseases is eliminated. The whole external wall coating decorative coating cost is reduced by more than one third.
In order to realize the aim, the exterior wall coating primer coating process adopts the following technical scheme:
firstly, the method comprises the following steps: the first pass is roller coating or brush coating (because the spraying can not reach the deep dipping effect, the gripping force is not available, and the roller coating or brush coating is also needed to be assisted to spray coating).
II, secondly: in practical application, according to the color of the wall body, the primer coating process adds the color with contrast into the primer, which is beneficial to clear quality inspection.
Thirdly, the steps of: after the first primer coating, the second primer with the reverse color difference developed by the company is coated after being dried for more than 48 hours (the second primer can be sprayed).
Fourthly, the method comprises the following steps: and (5) after drying completely, delivering to a finish coating construction team.
The invention has the beneficial effects that: the construction is simple and the effect is obvious. The invention relates to a saw invented by Luban, which is based on the principle that a plant left-hand button cuts a tooth to cut a finger, so that the primer construction process is based on the principle that people cannot pull up the developed and flourishing root system of the plant, and a corresponding primer is designed. The primer is combined with the construction process, and the service life of the coated building exterior wall coating can reach more than twenty years. The cost of recoating after twenty years is only half of that of tile cleaning. No hidden trouble of environmental pollution caused by strong acid and alkali wastewater generated by cleaning the ceramic tiles exists. In terms of product quality, if the top coat is stripped or faded, and the primer is intact as before, the responsibility can be visually distinguished.
Drawings
The invention is further illustrated with reference to the following figures and examples:
FIG. 1 is a flow chart of the construction method of the present invention.
Detailed Description
The invention will now be further illustrated by the following examples.
A primer coating process for exterior wall paint comprises the following steps:
firstly, the method comprises the following steps: the first time of the coating is roller coating or brush coating (spraying can not be carried out, no holding power is generated because the deep dipping effect can not be achieved by spraying, and roller coating or brush coating can be carried out when the spraying is carried out).
II, secondly: in practical application, according to the color of the wall body, the primer coating process adds the color with contrast into the primer, which is beneficial to clear quality inspection.
Thirdly, the steps of: after the first primer coating, the paint is dried for more than 48 hours, and then the secondary primer with the reverse color difference developed by the company is coated (the secondary primer can be sprayed).
Fourthly, the method comprises the following steps: and (5) after drying completely, delivering to a finish coating construction team.
Claims (4)
1. The first primer is coated by rolling or brushing, and no holding power is generated because the spraying effect cannot be achieved by deep dipping. Note that: the spraying should be assisted by rubbing to make up for the deficiency of rolling or brushing.
