Solvent-free polyurethane super wear-resistant floor has superior surface hardness and scratch resistance, which is especially suitable for wear-resistant finish surface in frequent traffic areas.

1. Plain treatment

The ground was polished and removed with a dust-free grinding machine as a whole, and the floating dust was cleaned. The cracked part of the floor was scraped and repaired with epoxy resin and quartz sand, and then the ground surface was treated with a grinding machine to make the ground smooth, without falling off and powder. After the grinding and construction, the water content should be tested according to the ground conditions. A floor moisture meter can be used or a professional's experience can be used to lay a 2m*2m complete film flat on the ground, with drying paper placed at the bottom of the film and sealed around it. After 72 hours, take out the drying paper, if it can be lit, it can be constructed; Can not be lit or intermittent construction.

2. Construction method
① Epoxy resin sealing primer and oil proof primer construction
The main agent of epoxy resin sealing primer is thoroughly stirred, and then the curing agent is added to the main agent according to the ratio of main agent and curing agent strictly. The curing agent is thoroughly stirred with a professional portable mixer, and then rolled or scraped on the cleaned ground. After it is fully permeated, if it is found that the local white, leakage or no light, according to the situation, it can be rolled again locally to ensure the sealing effect of the bottom coating.
Note: Epoxy closing primer shall be allowed to cure for not less than 8 hours after construction.
② epoxy resin mortar coating construction
A. Middle coating construction of epoxy resin (adding quartz sand)
The main agent of the coating material in the epoxy resin is stirred evenly, and then the curing agent is slowly poured into the main agent according to the ratio of the main agent and curing agent strictly, and a professional portable mixer is used to fully stir evenly and add an appropriate amount of quartz sand, and fully stir evenly. Then on the ground with a scraper to do a layer of batch, fill up the local damage, so that the surface is smooth.

B. Coating construction of epoxy resin (adding quartz powder)
After the ground is hardened and dry, the ground is fully sanded, and then the ground dust is sucked up by a vacuum cleaner, and then the construction of a quartz powder coating is carried out. The main agent of the coating material in the epoxy resin is stirred evenly, and then the curing agent is slowly poured into the main agent according to the ratio of the main agent and curing agent strictly. The curing agent is fully stirred evenly with a professional portable mixer and an appropriate amount of quartz powder is added, and the mixture is fully stirred evenly. Then on the ground with a scraper to do a layer of batch, fill up the local damage, so that the surface is smooth.

For the cracked ground, it is necessary to repair several times to ensure the overall consistency and tensile resistance of the epoxy floor, and ensure that no obvious cracks appear on the surface after construction.
Note: The middle coated mortar added with quartz sand shall be completed in one whole construction. During the construction process, the tip of the scraper shall be used to remove the large bubbles and pick out the impurities and particles. For the poor ground flatness after construction, it shall be repaired several times in a small scope to ensure the overall flatness.

(3) grinding
After the epoxy resin mortar is completely dried, polish it with a polishing machine and sandpaper to remove the knife marks, unevenness and particles generated by batch coating, and clean the dust with a vacuum cleaner.
④ Epoxy resin floor paint construction (scraping)
After polishing, the construction of epoxy floor paint is carried out. According to the ratio requirements of epoxy floor paint, first stir the main agent evenly, and then pour the curing agent into the center of the barrel containing the main agent to avoid uneven mixing of materials. After mixing well, after 15 minutes, let it fully react and mature, and then use a special floor scraper to scrape the whole.

⑤ Solvent-free polyurethane super wear-resistant floor paint construction (rolling coating and scraping)
After the epoxy floor paint dries, mix it according to the ratio requirements of solvent-free polyurethane super wear resistant topcoat to avoid uneven mixing of materials. After fully mix, 15 minutes after the interval, make its full reaction, curing, reoccupy special floor paint scraper blade coating construction of whole, and used the professional cross roller coating construction workers wear cleats, coating as evenly as possible, the thinner the better, if in the mixing barrel coating show hardening state, must stop using replace at any time and stirring barrels.
