AURO water-thinnable, solvent free finishes do not contain biocides and are therefore great for cots and children toys. The floor finishes keep wood looking close to their original colour and do not 'fire' or darken the wood like oil based finishes. We do not recommended these finishes for woods rich in tannins, such as oak and cherry wood due to increased drying times. It is essential to remove old varnishes and paints before applying these finishes.
