General construction methods of floor paint: 1. Floor surface treatment 1. The newly completed industrial floor must be maintained before construction, about 28 days. 2, remove the surface of cement slurry, old paint and adhesion of garbage debris. 3. Thoroughly remove the oil from the surface and use the king oil cleaner. 4, clear up the water and make the tide completely dry. 5, surface cleaning must be done with dust-free sweeper and large vacuum cleaner. 6. The smooth surface allows 2 to 2.5mm voids, and the water content is below 6%, pH 6~80. 7. The surface of the floor must be finished with a dust-free grinding machine and thoroughly cleaned with a vacuum cleaner. 8. Use putty to fill and scrape holes and obvious depressions on the surface of the floor. After dry, grind and dust.
Two, finishing the closed coatings
1. In the treatment of clean, flat concrete surface, the use of high-pressure airless spraying or roller coating, epoxy sealed primer together.
2. Epoxy sealing paint has very strong permeability. A certain amount of diluent should be added to the primer to make the diluted primer penetrate into the interior of the base layer and enhance the adhesion of the coating and the base layer. The coating must be continuous and uninterrupted. The coating amount should be based on the surface saturation.
3. Partial leakage can be repaired by brush. Surface redundant primer must be polished before the next process.
Three. Batch scraping batch scraping.
1. Two batches of scraping putty are used on the surface of the primer after drying (25 C, about 4 hours) to ensure the performance of the floor, such as wear resistance, pressure resistance, collision, water, mineral oil, acid and alkali solution, and to adjust the surface smoothness. 2. Using 100-200 mesh quartz sand and epoxy batch scraping material as the first putty, it is necessary to mix well and scrape flat. This method is mainly used to enhance the wear resistance and compression resistance of the ground.
3, use sandbag type dust-free rolling mill to polish first putty and clean it.
4. Using 200-270 mesh quartz sand and epoxy batch scraping material as the first putty, it is necessary to mix well and scrape flat, which is mainly used to enhance the wear resistance and smoothness of the ground.
5, use sandbag type dust-free rolling mill to polish second putty and clean it.
6. After the two putty dry, if there are pockmarks, cracks should be first repaired, and then use a flat sander to grind, make it flat, and clean dust.
7. The number of quartz sand used is determined by the field engineer according to the specific conditions of the ground.
Four, finishing the middle floor of the floor.
1. Use epoxy floor coating to finish the middle layer on the polished and cleaned putty surface (20 C, 24 hours). The coating method can be brushed, scraped, high-pressure air-free spraying. High-pressure air-free spraying is the best for large-area application, and the spraying pressure is 20-25 Mpa.
2. This time can make the ground more leveled, and it is more convenient to find the defects of the ground, so as to leveling the construction of the next layer.
3, it is also convenient for Party A to arrange equipment installation and so on.
Five. Finishing floor surface
1. After the middle layer is dry, the epoxy floor coating is carried out. The coating method is batch scraping and high-pressure air-free spraying, but the high-pressure air-free spraying is suitable.
2, before painting, sandbags and dust-free roller grinders in the middle layer shall be ground and vacuumed.
3. For example, after Party A has done the installation and debugging of the equipment in the middle layer, new defects are formed on the ground, which are leveled and polished by batch scraping material, and sprayed on the surface layer after dust collection and cleaning.
Six. Matters needing attention in construction
1. The ambient temperature of the construction site should be higher than 5 degrees C. when the relative humidity is less than 85%, the construction can be carried out.
2. The builder should make a good record of the construction site, time, temperature, relative humidity, surface treatment of the floor, materials and so on for reference.
3. After coating construction, the equipment and tools should be cleaned immediately.
Construction method of epoxy mortar floor paint:
1, grass-roots treatment:
Remove floated slurry, soil, cement and other pollutants to ensure that the ground and bottom oil are firm and firm.
2. Bottom oil construction:
The surface is closed, so that the bottom oil can fully penetrate the ground, enhance adhesion, and make the surface coating smooth and smooth.
The ground water content should be measured before the bottom oil construction. If the water content is higher than 5%, the water cut should be treated or the ground should be re-maintained, and the water content should be met before the construction.
When the bottom oil is constructed, mix the material evenly in proportion, and apply it to the plain by rolling or scraping.
It should be evenly glossy and uneven for second times. Generally, it can be painted in 24 hours.
3. Middle coating construction:
Carry out batches of construction for poor or uneven ground. After the bottom oil is solidified, it will be mended.
Mix batching materials proportionally and mix well. After drying, sand milling is done, and then vacuum cleaner is used to clean and prepare for surface coating.
4, surface coating construction:
After curing, pour the prepared surface coating on the ground and spread it evenly with a trowel. The spread times should not be too many to avoid a large number of bubbles and scratches.
5, surface coating maintenance:
During the two day period, no person should be allowed to be exposed to the surface coating, and should not be exposed to chemicals such as water, acid or alkali within 7 days.
If you smear it carelessly, wipe it immediately with a dry cloth.
Note: the above is the basic construction technology of epoxy resin floor. According to the difference of epoxy resin floor, additional other construction procedures are added.
The surface of vegetable land is required to be dry, with moisture content less than 8%. There is no sand, pulverization, empty drum or cracking on the surface. The grass-roots vegetable land should have a waterproof layer (the original vegetable land has been constructed).
