Processing information	The floor must first be sanded back to the bare wood and be dry and free from oil, grease, wax, silicones and sanding dust.. Apply the PRIMER evenly with a suitable roller. Large areas should be coated by several people at the same time. Shake the lacquer well! Press the insert sieve into the pouring hole, fill the lacquer into a suitable paint kettle and work from that! Do not use a mechanical mixer as there is a risk of foam or bubble formation! After drying for 1 - 2 h / 20 °C room temperature and with adequate air circulation, apply the suitable sealant without prior sanding. Clean work equipment with water. Dried lacquer residue can be removed with Hesse CLEANING-AGENT DV 9.
