Preparation & Application
This product is a finish coat and should be applied over an appropriate primer or intermediate coating. All surfaces to be coated should be dry and cleaned as necessary to remove all oil, grease, salts or other contamination
Mix only in the proportions stated, mixing each component individually then together using a mechanical agitator. Agitate periodically during use to ensure product remains homogeneous.
Only apply in conditions of good ventilation which must be maintained during drying and curing. Do not apply when rain, mist, sleet or snow are imminent. During application and drying time of the paint coating, the surface should be dry, the Relative Humidity should not exceed 85% and the steel temperature should remain at least 3oC above the dew point. Only apply this product when the above conditions can be maintained throughout the critical application and drying/curing process. Paint temperature should ideally be at a minimum of 15ºC.
Airless Spray: Output fluid pressure at tip 2200-2500 psi, Tip Size: 13-17 thou (0.33-0.43mm). For application by airless spray up to 5% 1737 Thinner may be added for application under cool conditions and to apply at lower dft’s. For conventional spray up to 10% 1737 Thinner will be necessary. Maximum dft by this method is 75 microns. This product is suitable for application by brush or roller, but due to its fast drying properties intricate structures should be avoided.
Drying/Overcoating times at +5oC (@ 50µm dft): Dust free – 3 hrs; Hard dry – 9 hrs; Min overcoating – 24hr. Overcoat with itself or ViterThane PLV only. For optimum opacity use a primer/undercoat of a suitable shade. High humidity and condensation will impair gloss if exposed during application and curing. Some shades (2906 line) may contain lead based colourants and these are labelled (L). Contains isocyanates – refer to Safety Data Sheet.
It is your responsibility to read the Product Data Sheets (available below) before you place an order and prior to application of the product. The content of this website is our best recommendation and is not advice. Coverage rates quoted are approximate, you agree that coverage depends on the condition of the substrate, surface absorption, texture and application method. We ALWAYS recommend a trial area is coated to ensure the product meets your requirements before use.
