③ Grinding: after the epoxy resin mortar is completely dry, use a grinder, sandpaper, etc.
During the construction process, use the blade tip to remove the blisters and pick up the foreign particles.
The film bottom is placed with dry paper and sealed around.
Then, a layer of batch coating shall be made on the ground with a scraper, and the local damage shall be filled to make the surface flat.
After fully mixing, let it fully react and mature after an interval of 15 minutes, and then use a special floor scraper to scrape the whole coating.
After 72 hours, take out the dry paper and start the construction if it can be ignited; Construction is not allowed if it cannot be ignited or interrupted.
The poor ground flatness after construction needs to be repaired several times in a small range to ensure the overall flatness.
④ Construction of epoxy resin floor finish (batch scraping) after polishing, the construction of epoxy resin floor finish shall be carried out.
The plain ground shall be polished with a dust-free grinder, the ground shall be polished and removed, and the floating dust shall be cleaned.
Construction method: ① for the construction of epoxy resin sealing primer and oil-proof primer, the main agent of epoxy resin sealing primer shall be fully mixed evenly, and then the curing agent shall be added to the main agent in strict accordance with the proportion of the main agent and the curing agent.
The more uniform the coating is, the better the thinner the coating is.
According to the proportioning requirements of epoxy resin floor finish, the main agent shall be mixed evenly, and then the curing agent shall be poured into the center of the barrel containing the main agent to avoid uneven mixing of materials.
The cracked part of the floor shall be scraped and repaired with epoxy resin and quartz sand, and then the cement base surface shall be treated with a grinding machine to make the ground flat, free of falling off and powdering.
Construction steps of solvent-free polyurethane super wear-resistant floor: 1.
Epoxy resin intermediate coating construction (adding quartz powder): after the ground is hardened and dried, the ground is fully sanded, then the dust on the ground is absorbed by a vacuum cleaner, and then a layer of quartz powder intermediate coating construction is carried out.
Note: the curing time of epoxy resin sealing primer shall not be less than 8 hours after construction.
At the same time, workers wear nail shoes and use professional rollers for cross coating.
② Epoxy resin mortar intermediate coating construction a.
(solvent-free polyurethane super wear-resistant floor) 2.
The solvent-free polyurethane super wear-resistant floor has excellent surface hardness and scratch resistance, especially suitable for wear-resistant finish in areas with frequent traffic.
A 2m * 2m complete film can be laid on the ground by using the floor moisture meter or according to the experience of professionals.
After fully mixing, after 15 minutes, let it fully react and mature, and then use a special floor scraper to scrape the whole batch.
Note: the intermediate coating mortar added with quartz sand must be completed at one time.
After the polishing treatment is completed, the moisture content shall be tested according to the ground conditions.
A floor circle with millions of people.
to polish the knife marks, irregularities and particles generated by the batch coating, and use a vacuum cleaner to clean the dust.
Then, a layer of batch coating shall be made on the ground with a scraper, and the local damage shall be filled to make the surface flat.
After it is fully penetrated, if it is found that there is local whiteness, missing coating or no brightness, it can be rolled again locally according to the situation to ensure the sealing effect of the primer.
Stir the main agent of epoxy resin intermediate coating material evenly, then slowly pour the curing agent into the main agent in strict accordance with the ratio of the main agent and the curing agent, fully mix with a professional portable mixer and add an appropriate amount of quartz powder to fully mix.
epoxy resin intermediate coating construction (add quartz sand) mix the main agent of epoxy resin intermediate coating material evenly, then slowly pour the curing agent into the main agent in strict accordance with the proportion of the main agent and the curing agent, fully mix with a professional portable mixer, add a proper amount of quartz sand, and fully mix evenly.
(solvent-free polyurethane super wear-resistant floor) ⑤ construction of solvent-free polyurethane super wear-resistant floor finish (roll coating and scraping) after the epoxy resin floor paint is dry, the proportion shall be in accordance with the proportion requirements of solvent-free polyurethane super wear-resistant finish to avoid uneven mixing of materials.
b.
The professional portable mixer shall be fully mixed evenly, and roll coated or scraped on the cleaned ground.

If the coating in the mixing barrel is in a hardened state, it must be stopped and the mixing barrel must be replaced at any time.
The cracks on the ground must be repaired for many times to ensure the overall consistency and the tensile strength of the epoxy floor, and ensure that there are no obvious cracks on the surface after construction.
