If your paint sprayer is spraying globs, it's likely due to an issue with the paint itself. If the paint is too thick, it won't flow properly through the sprayer and will come out in globs. To fix this, you'll need to thin the paint so that it's the proper consistency.
There are a few ways to thin paint. You can add water to the paint, which will make it thinner and easier to spray. You can also add a paint thinner, which is a chemical that helps to thin the paint and make it easier to spray. Be sure to follow the instructions on the paint can or the paint thinner can to know how much to add.
Once you've thinned the paint, test it out in the sprayer to see if it's the right consistency. If it's still too thick, you may need to add more water or paint thinner until it's the right consistency.
