What To Do With Airless Spray Gun Between Coats?

Airless spray guns are impressive tools that make painting a breeze. Their efficiency in delivering a smooth and even coating is unmatched. However, as much as they are great, they come with their fair share of challenges. One of the most common questions that users ask is what to do with the gun between coats. In this article, we will discuss tips on what to do with an airless spray gun between coats.

Clean the gun

Cleaning the gun is the most crucial step between coats. Failing to clean the gun can lead to clogs, drips, and uneven spray patterns. The paint will also dry on the tip and the gun, making it difficult to remove. It is advisable to clean the gun immediately after use. If you are taking a break between coats, you can clean the gun and store it. Here is how to clean an airless spray gun:

Disconnect the gun from the hose and remove the filter and tip.

Flush the gun with the appropriate cleaning solution, following the manufacturer’s instructions.
Use a soft-bristled brush to clean the gun’s components thoroughly.
Rinse the gun with water and let it dry before storing it.

Store the gun

Storing the gun correctly is also essential. Improper storage can damage the gun, and you may end up having to replace it. Here are some tips on how to store your airless spray gun between coats:

Store the gun in a dry and cool place.
Hang the gun by the handle or store it upright to prevent paint from settling at the bottom of the gun.

Keep the gun away from direct sunlight and heat sources.
Protect the gun’s tip from damage by placing a cover over it.

Keep the paint wet

If you are taking a short break between coats, you can keep the paint wet in the gun. This technique is known as back-buttering. Back-buttering involves covering the gun’s inlet and spraying a small amount of paint into a container. This creates a vacuum in the gun, preventing the paint from drying. Here are the steps to follow:

Pull the trigger to release any pressure in the gun.
Cover the gun’s inlet with a rag or tape.
Spray a small amount of paint into a container.

Release the pressure by pulling the trigger.
Repeat the process after a few minutes to prevent the paint from drying.

Conclusion

Knowing what to do with your airless spray gun between coats is essential in achieving a smooth and even finish. Cleaning and storing the gun correctly will prolong its lifespan and prevent clogs and drips. Keeping the paint wet is also an excellent technique for short breaks. By following these tips, you can achieve a professional-looking paint job with ease.
