The foundation must be scraped, roughened, and cleansed to remove rust, dirt, alga, and fungus, and make the base surface clean, and after which, provide a groundwork suitable to the surface before applying OPTIMUS. The curing period for concrete or mortar should be at least 3 weeks; ensure that the water content is 10% or below and pH 9.5 or below before applying OPTIMUS. |

Roller coating process
- Groundwork
- Ensure to completely remove the flaking old paints and ballooning when coating OPTIMUS pertinent to remodeling. Use a solvent to wipe off oil stains from the surface, and fix any cracks before applying OPTIMUS.
- Cleaning
- Dust and dirt left on the surface can weaken the adhesion, which may cause ballooning, flaking, and/or other problems. Make sure to appropriately clean the surface. When applying OPTIMUS on wallpapers, wipe the surface with a damp cloth to clean it before applying the coating.
- Undercoat
(primer coating)
- We have various primers for different groundwork (see attachment). Portions where the primer is heavily absorbed should be coated again with the primer.
- Stirring method:
- Before coating, use an electric agitator to stir until all the paint is evenly mixed, otherwise the aggregates in the coating may appear on the surface.
- Final coating:
2 layers (painting method)
- When applying the coating, do not stick with one direction. Ensure to apply it both vertically and horizontally (otherwise the special aggregates in the paint may be unevenly spread, which may cause a defective finish). Also, strictly comply with the standard amount of paint.

Spray
*A special primer is available for the base material specified in the parenthesis (Inquire as appropriate)
* Use a primer suitable for the base material.
