Spray painting with a pressure pack can be one of the most economical and simplest methods for most people to actually spray paint. There is no mixing of paint required and any need to pour paint from container to container is completely eliminated. No spray gun or expensive compressors are required either.
Essential steps to follow prior to spray-painting using the pressure pack are firstly thoroughly prepare the surface to be spray painted. Start by washing or cleaning the surface so no grease oil or dust that may interfere with adhesion of the paint exists. Carefully sand or abrade the surface to ensure a smooth surface exists and also to provide a key for the new coats of paint you are about to apply.
With any spray paint pressure pack always shake the can thoroughly prior to spray painting to ensure the paint is completely mixed. Spray painting pressure packs have a steel ball which will rattle while you are shaking the pack and this ball assists in mixing the paint inside the can.
Following surface preparation and mixing of the paint within the pressure pack carefully mask out any areas that you do not want painted.
Give the spray paint pressure pack another quick shake and then spray out into the air quickly to ensure the nozzle is turned the right way. If the spray fan pattern is in the right direction you're okay if it's not you may need to turn the small plastic nozzle on the spray pack to change the spray pattern.
When ready begin moving the pressure pack and then squeeze the nozzle to start spraying and continue moving in a steady manner holding pressure pack at 90 degrees to the surface you are spray painting. It is usually better to apply multiple light coats of spray paint using a pressure pack rather than try to cover in one coat which can cause paint runs.
