Paint Spraying

[Ray White]

Something which has so far been omitted is humidity. I rely on a hygrometer. This cheap devise is useful because if you apply paint when there is more than 50% humidity there is a risk of micro blisters that will spoil your paint a few weeks later.

Another thing to remember is that no matter what size your compressor, the air that reaches the gun must be dry. Air as it comes out of the compressor is hot and wet so a good coalescing filter is essential as it will not only remove vapour but also oil aerosols and other micro contaminants.

Hope this helps.
