Products in use
It is important that both wood and lacquer have a temperature of min. 15°C (preferably around 20°C) and air humidity of approx. 50%. Make sure that the room is well-ventilated for optimal evaporation and drying time. For the final sanding to bare wood, use grit 100-120 sandpaper or sanding pad. Vacuum thoroughly and wipe the floor down afterwards, using a tightly-wrung water-soaked mop/cloth. Please note: WOCA Intensive Wood Cleaner can help to remove contaminates from fully sanded wooden floors before priming or lacquering. Please allow floor to fully dry overnight. The floor must be completely dry before priming or lacquering. When priming, use WOCA Master Base Primer for newly sanded wood to reduce side bonding. Alternatively, try WOCA Master Multi Primer for exotic wood species or old wood previously treated with oil or wax.
