How to Stop Spray Gun Spitting
Spray guns are great for painting interior walls, cabinets, exterior walls and furniture. They apply an even coat to the painting surface and painting time is much quicker compared to using brushes and rollers. One of the common problems with spray guns is the gun spitting paint, causing excess paint drops and debris to stick to the painting surface. The main causes of this are dried paint clogging the tip and paint that has not been thinned. You can fix your spray gun from spitting and prevent it from spitting in the future with a few easy steps.

Tips & Warnings
Your paint should be a mixture of 30 percent thinner to 70 percent paint to prevent spitting.
After each use of your spray gun, replace the paint with mineral spirits and spray the gun until the liquid coming out is clear. This will prevent paint from drying and clogging your paint gun.
Thinning your paint more than 30 percent can cause the paint to run on your painting surface.
