Surface preparation
Painted surfaces – These surfaces must be completely clean and free of any grease and other contaminants. Before painting, the surface should be completely dry and if a long time has passed since the application of the undercoat, a suitable roughness should be created by soft sanding on the surface. Steel surfaces – Wash the steel surface with a suitable solvent to remove grease, salt and any other contaminants. De-rust and create profiles on surfaces by various methods such as sand blasting up to 2.5 degrees Swedish or by mechanical tools up to ISO-ST3 degree. In metal structures and welded points and corners should be smooth and polished and free of any appendages and sharpness. After de-rusting and creating a profile, remove the particles from the preparation and other contaminants from the surface with a pressure of air free of moisture and grease and with the method of vacuum and thoroughly clean. Note that the application of the first layer (primer) should be done no later than two hours after preparation. Concrete surfaces – If the concrete is fresh, it must be 28 days after the concrete has been applied (the concrete surface is completely dry). If the concrete is old, the surface must be washed with fresh water to remove contaminants such as salts, grease, dust and Dust, loose and unstable particles, etc. from its surface

Staining instructions
After preparing the surface and choosing how to paint, first stir the paint to mix thoroughly, making sure that no sediment remains at the bottom of the container. Add the appropriate amount of TVI thinner (the amount varies depending on the application method) to the mixture and stir until the color is applicable. Then apply the paint with the appropriate tools.
Storage and transportation
The above paint is flammable, so it should be sealed in a sealed container and kept away from moisture, fire, and strong currents of electricity and incendiary materials.
It is recommended to consume the contents of the container as soon as possible after opening the lid.
Suitable storage temperature is 20 degrees Celsius.
Safety
When applying paint, use safety equipment such as masks, goggles, cape and proper ventilation. In case of contact with skin, clean the area with a cloth soaked in a suitable solvent and wash with plenty of warm water and soap. Avoid breathing paint vapors, especially during application.
