Application note
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.
