Which practice helps ensure spray results are clean and consistent?

• A. Proper cleaning of spray equipment
• B. Using the same brush on all surfaces
• C. Prolonging tip cleaning until the end
• D. Skipping cleanup to save time

Answer: (A)

Maintaining clean spray equipment is essential for a uniform, predictable spray pattern. Residual material, dust, or solvents left in lines and the nozzle can dry, clog passages, or alter atomization, causing changes in flow, uneven patterns, color mismatch, or surface defects. Thorough cleaning removes old material and contaminants and includes flushing the system, cleaning the fluid tip and passages, the air cap, and the spray cup, plus checking for dried material between colors. This keeps viscosity, atomization, and the spray pattern stable, so the finish stays clean and consistent from start to finish. Prolonging tip cleaning allows buildup to occur and increases clogging risk, while skipping cleanup to save time invites contamination and defects. Using the same brush on all surfaces isn’t relevant to spray results and can transfer contaminants.
