Modern factories have very high requirements for floors, such as choosing common cement floors. The dust generated in the work not only harms the health of employees, but also causes damage to precision instruments, and even affects the quality of products. Therefore, almost all modern chemical plants will choose different floor painting systems to meet the needs of their different environments. In order to meet the above requirements, our Coating research and development center has developed an polyurethane flat-coated floor system specially for indoor floor of industrial plant. The system has high adhesion and load, and has the advantages of strong, wear-resistant, smooth and clean, and cost-effective.
Application Range
It is suitable for non-heavy industrial plants, such as electronics, electrical appliances, machinery, chemical industry, medicine, textile, clothing, tobacco and other industries.
Warehouses, supermarkets, parking lots or other special places, including all cement or terrazzo floors.
Dust-free walls and ceilings with purification requirements.

Construction technology
Process name | Specific practices and requirements | Reference dosage |
Primer layer | 1: Mix common polyurethane one-component primer or high solid polyurethane primer (main paint: curing agent = 5:1) and mix well. 2: Use roller, brush uniform brush, no leakage coating. | 0.12-0.2kg/㎡ |
Putty layer | 1: Use ordinary polyurethane paint(1:1) or high solid polyurethane paint (5:1) mix proportionally and add appropriate fillers (such as quartz powder, talc powder) to mix evenly. 2: Scrape 1-2 times with batches of knives, with emphasis on filling holes in the ground. 3: To be cured, polish the knife marks and other defects, and clean them with vacuum cleaner, chicken feather duster, broom, etc. | 0.15-0.2kg/㎡ |
Surface layer | 1: Use ordinary polyurethane paint(1:1) or high solid polyurethane paint (5:1) mix proportionally. 2:Dip the paint on the prepared drum and roll it evenly. It is required that the coating be uniform and leak-free. Roll it twice. | 0.15-0.2kg/㎡ |
Wear resistant layer | 1:This process can be used according to customer's needs. 2: 12-24 hours after the completion of construction, curing to the pedestrians without any trace, rolling with polyurethane wear-resistant coatings can greatly improve the smoothness and wear resistance of the floor. | 0.2kg/㎡ |
