Shake the container at least 3 minutes after you hear the mixing ball. Before the first use spray it in the air for 3-4 seconds. After use turn the aerosol upside down and press the actuator for 2-3 seconds to clean the valve. If the nozzle is blocked, replace it with a new one. Use outdoors or in a well-ventilated area such as an open garage. Optimal application at temperature: 10-32°C and humidity below 65% to ensure proper drying. Do not use on objects that may exceed 90°C surface temperature. Storage 10-30°C.



Ensure the surface is clean, dry, and free of grease

Wear protective gloves, protective clothing, eye/face protection

Always paint in an open space in the open air

The space should be as dust-free as possible

Protect the surrounding area from overspray

Test spray on a non-visible area

Always spray with the can in a vertical position, otherwise the paint might 'spit' unevenly

Spray surface from a distance of 25cm

Apply in several thin layers, spraying in sweeping motions

Don't go over bits you have missed, but leave to dry and then re-varnish area. Don't go back over areas you have already done, as this can cause clouding

Don't attempt to remove once applied

Do not use with any non-acrylic media

After use, clean the spray valve (turn the aerosol upside down and push the nozzle for about 5 seconds)
