Generally speaking, the service life of epoxy flooring is 5-10 years. According to the different construction technology of epoxy flooring, the service life of epoxy flooring will also have some differences. The epoxy floor may be damaged in the use process and after reaching its service life. At this time, it needs to be renovated and repaired. In the case of partial epoxy floor damage, it is not necessary to renovate all of them. It is only necessary to clean the old epoxy floor coating in the damaged area, then polish it, and then construct it according to the construction technology of epoxy floor. 破损的旧环氧地坪
Damaged old epoxy flooring
1. Partial damage of epoxy floor
In the case of partial epoxy floor damage, it is not necessary to renovate all of them. It is only necessary to clean the old epoxy floor coating in the damaged area, then polish it, and then construct it according to the construction technology of epoxy floor.
Epoxy Floor after Renovation and Repair
2. Large area peeling and delamination of epoxy floor
For large area peeling and delamination of epoxy flooring, it can only be renovated and repaired as a whole. The specific steps are as follows:
1. Removal of old epoxy floor coating
Using professional epoxy wear equipment, the old epoxy floor coating is completely cleaned up, and then the dust and debris on the ground are cleaned up.
2. Clean up oil pollution
For areas where the ground is polluted by oil pollution, it is necessary to remove the oil pollution. Generally, cleaning agent is used to achieve degreasing and degreasing effect. It is necessary to ensure that the surface is clean before construction, otherwise the quality of epoxy engineering will be affected.
3. Repair cracks
If the floor is used for too long, especially in the early stage, if the material selection of the floor fails to pass, cracks will occur over time or due to human factors. At this time, we need to solve the problem first and then do renovation work. The treatment method is to use the cutting machine to cut the cracks into V-shaped grooves, and then irrigation. Enter epoxy mortar to make it smooth.
4. Construction of epoxy primer
The primer should be fully stirred by electric mixer according to the material usage instructions. The primer should be uniformly coated with batch knives on the surface of the base layer. Where the penetration of the primer is very strong, it should be painted again. The next working procedure should be carried out after 12 hours.
5. Construction of Epoxy Medium-coated Mortar
Mix and mix the medium coated material with proper amount of quartz sand, scrape the surface evenly with batch knife, and then grind the ground with dust-free grinder after solidifying completely, and then use vacuum cleaner to absorb dust and grind smoothly.
6. batch repairing of putty in epoxy
Medium-coated materials with quartz fine powder batch coating are used to fill the gap between the larger particles in the medium-coated coating. After fully solidified, the ground is polished by a dust-free grinder, and the dust is sucked up by a vacuum cleaner and polished flat.
7. Construction of Epoxy Surface
Construction method of epoxy plain coatings: epoxy putty is cured, polished, polished and cleaned, epoxy resin finish material is mixed according to the proportion of component A: component B = 5:1, then scraped and coated with scraper first, after curing, defects are repaired and then rolled for the second time.
Construction method of epoxy self-flowing surface paint: The material of epoxy self-flowing surface coating is mixed in proportion of component A: component B = 5:1 and stirred well. The self-leveling surface is sprayed with a prepared trowel or with an airless spraying machine. If sand impurities are found to be removed immediately during construction, the mixing barrel coatings must be stopped and replaced at any time if they are in a hardening state.
8. Closed Maintenance
After the construction of the surface layer, the construction area of the epoxy flooring shall be maintained completely in four days to avoid dust intrusion, and the epoxy flooring shall not be upgraded until it is completely hardened.
