Environment temperature: 5-38℃
Relative humidity: 35-85%
The concrete surface should be PH<10, the substrate water content less than 10%
Dew point ≥3℃
Recommended dft: 1000 um
Interval time: min 3h, max 168h, if the maximum interval time is exceeded or there is dust on the surface, it is recommended to use sandpaper to polish and clean before application.
Coating method: scraping
To ensure the surface is perfect and clean, remove the oil, mold, dust and other attached dirt on the surface, also remove the loose part to make sure it is solid and dry.
Mix the paint evenly before use, pour out the amount to use up, and close the lid immediately. The mixed paint must be used up within 60 minutes. Do not return the remaining products to the original paint barrel.
Mix part A and part B in right ratio, then mix with quartz sand or quartz powder together for use.
Do not add organic solvents or other coatings.
