Spraying Techniques

Preventing Excessive Tip Wear

•Spray should be atomized (evenly distributed, no gaps at edges). Start at low pressure set- ting, increase pressure a little at a time until you see a good spray pattern, without tails.

•Spray at lowest pressure that atomizes paint.

•If maximum sprayer pressure is not enough for a good spray pattern, tip is too worn. See Reversible Spray Tip Selection Chart, page 16.

If tails persist when spraying at the highest pressure, a smaller tip is needed or the

material may need to be thinned.
