water based polyurethane weather resistant paint

Construction period range: 1.Conventional period: Usually 15-20 days are required to complete all processes. 2. Special epoxy terrazzo process: Some complex processes (such as epoxy gold terrazzo) require more than 20 days. 3.The curing time can be shortened to 48 hours in summer and extended to 24-48 hours in winter.  Key construction stages: Base preparation (2-3 days): Including cleaning, leveling and epoxy primer application. The moisture content must be controlled below 8%.  Surface paving and curing: After paving, the epoxy terrazzo layer needs to be cured for 24-48 hours (summer) or longer (winter). Inorganic terrazzo curing takes 7-10 days. Epoxy terrazzo curing takes shorter time but the process is more complicated. Grinding and polishing (3-5 days) It is divided into coarse grinding (diamond No. 60-90), fine grinding (No. 200-500), and fine grinding (No. 2000-3000) processes.  Finishing treatment (1-2 days) Including grouting, waxing and finished product protection.  Influencing factors Temperature: The curing time may be extended by more than 50% in winter. 12 Process complexity: Epoxy grindstone requires multiple repairs and layered curing, which takes 5-7 days longer than inorganic grindstone.
