Solvent-free polyurethane ultra-wear-resistant flooring construction steps.

Solvent-free polyurethane ultra-wear-resistant flooring has superior surface hardness and scratch resistance, and is particularly suitable for wear-resistant finish surfaces in areas with frequent traffic.
Solvent-free polyurethane ultra-wear-resistant flooring construction steps
1, plain treatment
with dust-free grinding machine overall grinding, ground grinding and eradication, cleaning floating dust, the floor has cracked part, with epoxy resin added quartz sand batch scraping repair, and then the use of grinding machinery to treat cement foundation, so that the ground flat, no shedding, no powdering and so on. After the grinding treatment is completed, the moisture content can be tested according to the ground conditions, using a floor moisture meter or according to professional experience, a 2m x 2m complete film tiled on the ground, the bottom of the film is placed with drying paper, sealed around . After 72 hours, remove the drying paper and work if it can be ignited;

2, construction method
(1) epoxy resin closed primer and anti-oil primer construction
After its full penetration, such as the discovery of local whitening, leakage or no light, according to the situation can be partially rolled again, to ensure the sealing effect of the bottom coating.
: Epoxy closed primer construction must be retained after not less than 8 hours of curing time.
(2) epoxy mortar coating construction
a, epoxy resin coating construction (add quartz sand)
the epoxy resin coating material main agent stirred evenly, and then strictly according to the main agent, curing agent ratio will slowly pour the curing agent into the main agent, with a professional portable blender fully stirred to add the appropriate amount of quartz sand, fully stirred evenly. Then on the ground with a scraper to do a comprehensive layer of cladding, fill the local damage, so that the surface is flat.

b, epoxy resin coating construction (add quartz powder)
to the ground hardened and dried after a full sanding, and then vacuum cleaner to absorb ground dust, and then carry out a quartz powder coating construction. Mix the main agent of the coating material in epoxy resin evenly, and then strictly according to the ratio of the main agent, curing agent will slowly pour the curing agent into the main agent, with a professional hand blender to fully mix the appropriate amount of quartz powder, fully stirred evenly. Then on the ground with a scraper to do a comprehensive layer of cladding, fill the local damage, so that the surface is flat.
the ground cracking site, it is necessary to carry out many repairs to ensure the overall consistency and the pull resistance of epoxy floor, to ensure that the surface after construction is not obvious cracks appear.
note: to add quartz sand in the mortar must be an overall construction end, the construction process, with scraper tip to remove large bubbles and pick out impurities particles, for the construction of the ground leveling is poor need to carry out a number of small-scale repair, to ensure overall flatness.

(3) grinding
after completely drying in epoxy mortar, polish with polishing machine, sandpaper, etc., will be the batch of knife marks, uneven places and particles polished off, and vacuum cleaner to clean the dust.
(4) epoxy floor paint construction (batch scraping)
to be polished after the construction of epoxy flooring paint. According to the ratio requirements of epoxy flooring paint, the main agent is stirred well, and then the curing agent is poured into the center of the barrel equipped with the main agent to avoid uneven mixing of materials. After full stirring, after 15 minutes of interval, let it fully react, cook, and then use a special floor scraper overall batch scraping.

(5) solvent-free polyurethane ultra-wear-resistant floor paint construction (rolling coating scraping)
After full mixing, after 15 minutes of interval, let it fully react, cook, and then use a special floor scraper overall scraping construction, while workers wear nail shoes using professional roller cross-coating construction, coating the more uniform the better, the thinner the better, if the paint in the mixing barrel presents a hardened state, must stop using and change the mixing drum at any time.
