Among them copper nozzles tend to hold the popularity.

Easy-cleaning Feature

You need to make sure that your spray gun for polyurethane, is easy to clean. For easy cleaning, there have to be additional brushes to clean the spray gun after using it. Again, to clean the nozzle, you need to have needles. Cleaning up your spray gun regularly after spraying is very important. While buying one, check whether they provide enough materials for cleaning or not. Also, make sure your gun can be dismounted easily. It can help you to clean up the whole construction without having any issue.


The net weight of your spray gun is equally important as you have to hold it for a long time while working. So, your spray gun needs to be lightweight to get comfortable working experience. The spray gun should not be more than 7 pounds, with accessory. In our listed products, we have maintained the lightweight feature that will help you with easy portability.

Power Cord Length

Some of the spray guns have a really low-length power cord. Sometimes it creates problems while working in a large area. The length of the power cord has to be at least 6 ft for fair use.
