The construction of epoxy self-leveling mortar is a work with high technical content, which needs to follow certain construction steps and precautions. This article will introduce the technological process, technical points and quality control measures of epoxy self-leveling mortar construction in detail to help readers better understand this construction technology.
1. Construction preparation.
Before construction, adequate preparation is required. First, clean the construction site to ensure that the surface is free of oil, dirt and other impurities. Secondly, the ground is pre-treated, such as repairing cracks, filling holes, etc., to ensure the construction effect. In addition, it is necessary to prepare the materials and tools required for construction, such as epoxy self-leveling mortar, agitators, drums, scrapers, etc.
2. Material preparation.
The preparation ratio of epoxy self-leveling mortar needs to be adjusted according to the actual situation, and it is generally prepared according to the ratio provided by the manufacturer. In the preparation process, precise metering tools should be used to ensure the accuracy of the proportion. At the same time, the material should be fully stirred so that it is evenly mixed and free of color difference and particles. The prepared epoxy self-leveling mortar should be used as soon as possible to avoid long-term storage.
Third, the construction process.
1.Primer: Before application, a primer is applied to the floor to increase adhesion. The primer should be evenly applied, and there should be no omissions or accumulation. Wait for the primer to dry after applying.
2.Mortar laying: The prepared epoxy self-leveling mortar is evenly laid on the ground and bulldozed using a scraper or roller. In the laying process, attention should be paid to controlling the thickness of the mortar to avoid uneven thickness or mortar accumulation. After the mortar is laid, it is necessary to wait for a certain amount of time for it to level naturally.
3.Mortar curing: After the mortar is naturally leveled, it needs to be cured. The curing time should be controlled according to the parameters provided by the manufacturer to ensure that the mortar is fully cured. During the curing process, attention should be paid to the changes in temperature and humidity to avoid affecting the curing effect.
4.Mortar grinding: After the mortar is cured, it needs to be sanded to remove the surface burrs and uneven parts, so that the ground is smoother and smoother. When grinding, professional grinding tools should be used to polish in a certain direction and order to avoid cross-polishing marks. After sanding, the surface needs to be cleaned.
5.Topcoat Painting: Finally, a topcoat is applied to the surface to increase aesthetics and abrasion resistance. The topcoat should be applied evenly and without color difference, and the topcoat should be allowed to dry after painting.
4. Precautions.
1.During the construction process, attention should be paid to protecting the cleanliness and safety of the construction site to avoid mortar scattering and polluting the surrounding environment.
2.When mixing and preparing epoxy self-leveling mortar, attention should be paid to avoid uneven mixing of materials or chemical reactions, which will affect the construction effect.
3.In the construction process, attention should be paid to controlling the thickness and leveling of the mortar to avoid uneven thickness or uneven surface.
4.During the curing process, attention should be paid to the changes in temperature and humidity to avoid affecting the curing effect and construction quality.
5.During the grinding process, attention should be paid to protecting the surface of the mortar from damage and avoiding scratches or breakage.
6.When applying the topcoat, attention should be paid to controlling the uniformity and thickness of the coating to avoid color difference or uneven painting.
5. Quality control.
During the construction process, strict quality control and quality inspection should be carried out. First of all, the ratio and mixing of the material should be checked to ensure that the quality of the material meets the requirements. Secondly, the construction process should be monitored and recorded, and problems should be found and dealt with in a timely manner. Finally, the construction results should be tested and evaluated to ensure that the construction quality meets the design requirements and use requirements. At the same time, the corresponding quality standards and testing methods should be formulated according to the actual situation to ensure that the construction quality is effectively controlled.
In a word, epoxy self-leveling mortar construction is a high-tech work, which needs to follow certain construction steps and precautions. In the construction process, attention should be paid to the preparation, preparation, process, precautions and quality control to ensure that the construction quality meets the requirements. At the same time, the management and supervision of the construction site should also be strengthened to ensure the safety and quality of the construction process. Through the implementation of reasonable construction and management measures, the construction quality and use effect of epoxy self-leveling mortar can be effectively improved, and the aesthetics and functionality of buildings or facilities can be effectively guaranteed.
