- Continue working as mentioned on the label of the corresponding presto product.
Avoid contact with eyes and skin! In case of contact with eyes, carefully wash off with a 5 % solution of natrium-ascorbate rinse with plenty of water for at least 15 minutes. Observe material safety data sheet!
Tips for spray painting
Protect the object and the surrounding area from spray mist. When painting small areas it is recommended that a piece of card is used as a mask, with a hole cut in it slightly larger than the area to be sprayed. The mask should be held 1 to 2 cm from the surface. With this method, the mainly part of the spray mist is brought under control. It recommends to mask parts not to be lacquered, to protect the surrounding against the spray mist.
The aerosol can should have room temperature.
Temperature should range between +10°C and +25°C, max. air humidity 60 %.
Store in a dry place. Protect from direct sunlight and other sources of heat. Use only during dry weather, in places protected from the wind, and in well-ventilated rooms. Follow the warning texts on the labels!
