APPLICATION DETAILS
Application conditions The surface to be treated has to be clean and dry. During application and drying the temperature of the air, the surface to be treated and the lacquer has to be over 18 ºC and the relative humidity of the air below 70 %.
Priming Recommended primers: Merit Sanding, Merit 20, Merit 30, Merit 80, Merit Sealer.
Surface treatment Wood surfaces should be sanded with sanding paper P150–240. Primer surfaces should be sanded with sanding paper P240–400. All sanding dust must be removed before lacquering.
Mixing of components Stir the lacquer carefully before use. Add 10 volume % of Hardener 006 2098. Thin the lacquer to the viscosity required. In case the lacquer mixture is used on the next day, add at least an equal amount of fresh mixture.

Do not use iron containers as mixing container. Instead use plastic, enamel or acid resistant steel containers.
Cleaning of tools Thinner 1033 or 1027.
EU VOC 2004/42/EC-limit value The Volatile Organic Compounds amount is 420 g/litre of paint.
VOC content of the paint mixture (thinned 20 % by volume) is 500 g/l.

HEALTH AND SAFETY LABELLING
according to Regulation (EC) No. 1272/2008
Containers are provided with safety labels, which should be observed. Further information about hazardous influences and protection are detailed in individual health and safety data sheets. A health and safety data sheet is available on request from Tikkurila Oyj. For industrial use only.
