- 1). Shut off the sprayer and check and clean the filters in your sprayer when stringy paint is clogging the paint or lowering the pressure. Check the inlet filter where the paint is being pulled from the bucket, the manifold filter on the body of the sprayer, and the filter inside the spray gun. The method of removing them will depend on the model, but you will probably need crescent wrenches or the tool kit that came with the sprayer.
- 2). Rinse the filters to remove contaminants like strings of paint. Replace them and run some clean water or solvent through the sprayer.
- 3). Strain your paint before starting to spray again. Use a paint strainer, available at any paint or hardware store, or a pair of clean nylons.
- 4). Add a drying retardant to the paint if there's a formation of fine strings that look like spiderwebs on the sprayed surface, if you can't lower the air or surface temperature. Anything that causes the paint to dry too quickly as it leaves the spray gun will cause spider-webbing.
- 1). Increase the pressure if the spray pattern fan is uneven, with two lines, fingers or "strings" of paint above and below the main fan.
- 2). Check the air cup if using a conventional sprayer to make sure the holes aren't clogged and lowering the spray gun pressure. Clean them with compressed air or solvent, never with a wire brush or any other hard metal object.
- 3). Make sure the material being sprayed is the correct consistency for spraying; material that is too thick can come out in an uneven spray pattern.
- 4). Consider replacing the spray tip if other methods don't work. Worn spray tips can also cause an uneven spray pattern.
