The surface treatment of epoxy floor to base material: the new concrete floor needs 28 days of curing period, compressive strength (> 20 MPa), drawing strength (> 1.5 MPa), and the concrete label requires more than C25; the surface is dry and the moisture content is less than 6%; the construction of waterproof and moisture-proof layer is completed below the base level; the surface defects of the base course, such as sand, empty drum, grease, crack, etc. Grain and so on. 2. Solvent-free epoxy sealing primer: whole grinding, dust cleaning and wearing one solvent-free epoxy sealing primer. The epoxy sealing primer is uniform, without leakage coating and material accumulation, and has no obvious whitening marks, and the paint film is full. 三、涂装无溶剂环氧中涂漆
Three. Solvent free epoxy coating.
The middle coat is usually scraped 2-4 times according to the thickness of epoxy floor.
1. Solvent-free epoxy coating is evenly stirred and then scraped with 70-140 mesh quartz sand. As the first epoxy mortar, it is mainly used to enhance the wear resistance and compression resistance of the ground.
2. Solvent-free epoxy coating is evenly stirred and then scraped with 200 mesh quartz sand. As the second epoxy mortar, it is used to enhance the wear resistance of the ground, repair the first defect and smoothness.
3. After the two epoxy mortars are dry, if there are flax surface and cracks, they are repaired first, then sanded with a sand table machine to make them smooth and clean. The number of quartz sand used is determined by the field engineer according to the specific conditions of the ground.
4, different types of floor should be written differently, for example, the epoxy anti-static floor also needs to be coated with conductive layer.
Four. Solvent free epoxy coating.
Epoxy surface coating methods generally include roll coating or epoxy self-leveling scraping, etc. Before painting, the intermediate layer should be polished and cleaned. Rolling coating construction generally consists of two routes. If scraping and painting is self-leveling construction, it is necessary to roll back and forth on the floor with defoaming drum to defoam, and finally let it self-leveling.
Five, construction precautions and safety technical requirements
The ambient temperature of the construction site should be higher than 5 C, and the relative humidity is less than 85%. Construction site, time, temperature, relative humidity, ground surface treatment and material reality should be recorded for reference.
Warning belts and warning signs should be put up around the construction site. Open fire operation and smoking should be strictly prohibited within 10 meters around the construction site. The use of electric tools must be responsible for someone who needs to cut off the power before leaving.
