MTN: How to Paint
This fact sheet covers the most basic and important information that you’ll have to take into account to guarantee the success of any project using spray paint.
STEPS TO FOLLOW TO ACHIEVE OPTIMUM RESULTS
When you want to paint a surface, you need to take a few preliminary steps before applying the paint.
Clean the surface, removing traces of dust, grease and rust. Use the right primer for the object you’re going to paint, if necessary.
Shake the can for one minute after hearing the sound of the mixing ball. To improve the mixture and make it easier for the ball to move, turn the can upside down.
Before applying paint to the nal surface, try it out on a test surface to make sure that the paint is well mixed and to get used to the ow of paint from the can.
Apply the paint from a distance of about 20 cm, which may vary depending on the stroke you want or the cap you use.
It’s always advisable to apply several thin layers than fewer thick ones. Be advised that the first layer may not be completely opaque. When applying different layers, always respect the drying times between them.
When you’ve finished painting, turn the can upside down and press the cap for a few seconds. You’ll see that paint gradually stops coming out after a few seconds and it will only spray gas afterwards. This means that both the inner valve and the cap have been cleaned of paint, preventing the can from drying inside and clogging up, so you’ll extend the useful life of both the spray can and the cap.
TROUBLESHOOTING
CRACKING
Cracks may appear due to different reasons like dry weather or incompatibility of paints.
The solution is to respect the drying times of each paint. BUBBLES
Can appear if you paint too close to the object or at high temperatures.
The solution is to apply the paint from the correct distance and not to paint in a space that’s too hot.
DRIPS
Drips can appear for three reasons:
• Buildup of paint
• Painting directly on the object without having done a test before
• Painting without having shaken the spray
To solve this, you have to:
• Paint at the right speed so as not to accumulate paint
• Try out the paint on a test surface or in the air until the colour comes out.
• Shake the spray for 1 minute after hearing the ball inside
