All brushstrokes should be made in the same direction for uniformity of appearance. A concrete etching tool can also be used within about twenty minutes of pouring. The resurfacing of concrete resurfacing has a working time of about 30 minutes. At 73 degrees and hotter weather, the working time will be reduced using cold mixing water and keeping the bags of concrete resurfacing shade. It will help extend the application time under normal conditions. No special curing is required, although in temperatures over ninety degrees, moisture with a fine water mist for 24 to 48 hours because concrete surfaces, polymer modified temperature should remain above 50 degrees for at least eight hours and should be protected from freezing for twenty four hours after application.
