If the ceilings are not installed already, it is not a problem. It is only because the Softwood Lye is a corrosive liquid. And liquids tend to drip down. So there is a risk of getting corrosive liquid on your arms and even worse; in the face and eyes and on the floors below. Therefore, we do not recommend using Softwood Lye on an already installed ceiling. Instead, Panel White, which is paint, is suitable for the lightening of yellowed wood, e.g. ceilings and wall panels.
NMP is a shortening for N-Methylpyrrolidone, which is an organic solvent. EU has recommended that NMP is changed to class T, category 2 because it may harm an unborn child. NMP is absorbed through the skin when the lacquer is wet. Therefore, WoodCare Denmark has among other things decided to produce Wood Floor Lacquer according to EU requirements.
