7. Application tips

Recommended dft: 100-200um (or according to design requirements)

Re-coating interval: 6-30h. If the coating time exceeds 30 hours or there is dust accumulation on the surface, it is recommended to use sandpaper to polish and clean before application.

Recommended coating methods: airless spraying, air spraying, brush, roller

Substrate treatment

Metal surface: It is recommended to sandblast to achieve Sa2.5 level according to ISO8501-1 or GB8923 standards.

Concrete surface: achieve a strong, dense, flat, clean, and dry state. There should be no phenomena such as sanding, shelling, cracks and honeycomb. Usually, putty is needed for repair.

Wood surface: clean, dry, without burrs, fragments, and loose debris.

The application treatment of other substrates please consulted with HUISINS technical personnel.

Application note

This product can be used at low temperatures below -10 ℃. When using in low-temperature environments, it is recommended to place the paint bucket in an air-conditioned room for at least 24 hours.HUISINS recommends mixing the paint evenly before use, pour out the accurate quantity of material that will use up in one time and seal well immediately. Don’t pour the rest liquid to the original bucket.The viscosity of the coating has been adjusted as needed when this product leaves the factory. thinner shall not be random added by the applicators. Call the manufacturer for the instructions of special thinner if the viscosity changed as the application environment and humidity.
