First, the treatment of epoxy floor surface 1, the new cement floor must be completed after a certain amount of conservation before construction, about 28 days.
2, remove the surface of the cement laitance, old paint and debris attached to the garbage.
3, thoroughly remove the surface of the oil, with grams of oil cleaning agent treatment.
4. Remove stagnant water and thoroughly dry the tide.

8. Epoxy mortar or epoxy putty should be used to fill the holes and obvious depressions on the surface of the epoxy floor to fill up the scraping, and then dry and dry.
Second, the coating strong osmotic closed curing epoxy primer 1, in the treatment of clean, smooth enamel surface, using high pressure airless spray or roller coating, epoxy sealer primer one.
2, epoxy sealing paint has a strong permeability, when the brushing primer should be added to a certain amount of thinner, so that the diluted primer can penetrate into the base layer, to enhance the adhesion of the coating and the base layer, its coating It must be continuous and uninterrupted. The amount of coating should be exactly saturated on the surface.
3. Partial coating can be applied by brush, and the excess surface primer must be polished before the next process.
Third, scrape the epoxy mortar coating material in the hard dry (25 °C, about 4 hours) after the primer surface using two methods of scraping putty to ensure that the epoxy floor wear resistance, pressure resistance, collision , water, mineral oil, acid and alkali solution properties, and adjust the ground flatness.
1. Use 70 to 140 mesh of quartz sand or corundum and solvent-free epoxy scraper as the first epoxy mortar. Stir thoroughly and evenly. This is mainly used to enhance the ground's wear and compression resistance.
2. Grind the first putty with a sand bag type dustless rolling sander and vacuum clean.
3. Use 200-700 mesh of quartz sand or corundum and solvent-free epoxy scraper as the second epoxy mortar. Stir thoroughly and evenly to enhance the wear and flatness of the floor.
4. Polish the 3rd epoxy mortar with sand bag type dustless rolling mill and vacuum clean.
5. After the two epoxy mortars are dried, any repairs shall be made to the surface of the plaster and cracks, and then polished with a flat sander to make it smooth and vacuum clean.
6. The number of meshes used for quartz sand is determined by field engineers based on the specific conditions of the ground.
Fourth, coating epoxy putty layer in the polished, cleaned epoxy mortar surface (20 °C, 24 hours) painted middle layer.
1. Finishing methods include brushing, scraping, high pressure airless spraying, and large area construction with high pressure airless spraying. (spray pressure 20 ~ 25Mpa).
2, this time can make the ground more flat, easier to find the defects still exist on the ground in order to level the surface construction.

3. After the paint is applied, the related equipment and tools should be cleaned immediately.
VII. Safety Technical Requirements 1. Warning tapes and warning signs should be put up around the construction site.
2. It is forbidden to open fire within 10 meters around the construction site and smoking is prohibited.
3, the use of high pressure airless spray pump should be grounded.
4, paint and thinner should be placed in a well-ventilated warehouse.
5. Pay attention to personal protection during work.
6, the use of power tools must be responsible for the person in charge, cut off the power before completing the departure.
VIII. Use and Maintenance 1. After the construction of the paint has been completed, do not use it during the maintenance period and strengthen the ventilation equipment and fire prevention measures.
2, floor use, production staff are not allowed to wear shoes with nails to walk on the top.
3. All work equipment must have a fixed special frame for placement. It is forbidden to touch the ground with objects such as sharp-angled metal parts, causing damage to the floor paint.
4. When heavy equipment such as equipment is installed in the workshop, there should be thick rubber and other software materials on the supporting points that contact the ground. It is forbidden to use iron pipes and other metals to pull the equipment on the ground.
5. When high temperature work such as electric welding is performed in the workshop, the asbestos cloth and other refractory materials shall be laid in places where the electric welding spark splashes to prevent burning of the paint.
6. Once the floor is damaged, repair the paint in time to prevent the oil from penetrating into the cement through the damaged area, causing large areas of paint to fall off.
7. When washing floors in a large area of ​​the workshop, do not use strong chemical solvents (toluene, banana water, etc.), use detergents, soap, water, etc., use a washing machine, and in the absence of a washing machine, use sawnwood powder. Sprinkle and then clean.
8, winter construction, the ambient temperature is lower than 5 °C, can use winter solvent-free epoxy industrial floor coating.
2, remove the surface of the cement laitance, old paint and debris attached to the garbage.
