Application conditions All surfaces must be dry. The temperature of the ambient air, surface or paint should not fall below +10 ºC during application and drying. Relative humidity should not exceed 80 %. The surface temperature of the steel should remain at least 3 ºC above the dew point.
Preparation Oil, grease, salts and dirt are removed by appropriate means. (ISO 12944-4)

Steel surfaces: Blast clean to grade Sa2½. (ISO 8501-1)
Finishing Fontedur HB 80, Fontecoat EP 50, Temacoat GPL-S Primer, Temacoat GPL-S MIO, Temacoat RM 40 and Temanyl MS Primer.
Painting By airless spray or brush. Agitate during application. Depending on the application method the paint can be thinned 20 - 50 % by volume. Airless spray nozzle tip 0.013" - 0.019" and nozzle pressure 160 - 200 bar. Spray angle shall be chosen according to the shape of the object. Sharp edges, corners, weld seams and other areas difficult to cover properly by spray application should be coated by brush before the spray application. At brush application the paint should be thinned according to the circumstancies.
Mixing of components First stir base and hardener separately. The correct proportions of base and hardener must be mixed thoroughly before use. Use Temaspeed Squirrel Mixer for mixing.
Cleaning of tools Water and Thinner 1029.
EU VOC 2004/42/EC-limit value The Volatile Organic Compounds amount to 180 ± 20 g/litre of paint mix thinned 40 % by volume.
