To comply with Korean VOC regulations, thinning is limited to a maximum of 5%. If using brush or roller, multiple coats are required to achieve the specified dry film thickness. Hempel's Roller/Brush Additive 99140 may be used to improve levelling. Consult Hempel for advice. Spray parameters are indicative and may be adjusted to site conditions. Pressure values apply to material at 20 °C. (*For other application methods, consult the company representative!).
