Maintain an even speed when spraying. 12. overlap each stroke by 50%. this will ensure even coverage as shown in figure 6. overlapping less than 50%, as shown in the figure to the right, may lead to missed spots or streaky results. no yes figure 6. overlap technique. 13. the spray stroke should have even consistency and parallel edges. if it doesn't please refer to troubleshooting on page 17. contamination hazard! dispose of paint waste in a responsible man- ner! follow manufacturer's recom- mendations and local laws regarding disposal.
