Basic DIY Steps for Painting With an Airless Paint Sprayer

Step 1

Prepare your airless sprayer for painting. Check the sprayer for damages, including checking the hose, gun, tip, and pump.

Fill the sprayer with water to check for leaks and look out for kinks and other damages on the hose.

Repair leaks using appropriate adhesives from your home appliance repair kit and clean the tip with a brush.


Never attempt to fix a damaged hose because this poses a risk of a potentially harmful projectile in case the hose breaks when in use. Replace a damaged hose with a new one instead.

Step 2

Assemble your airless sprayer parts together after ascertaining everything is in good condition.

Install the gun, hose, and guard and select the appropriate sprayer tip that will give you your desired finish. Your airless sprayer should be ready for use after all its parts are correctly assembled.


Sprayer tips come in varying sizes that determine, among other things, the width of your spray.

Refer to your operating manual that comes included in the airless sprayer purchase package for specific instructions on how to assemble the model parts and recommendations for sprayer tips to use to achieve desired finishes.

Step 3

Using paint sprayer for cabinets. Cover surrounding surfaces or furniture that you do not want to catch paint with spray shields or old newspapers and fill the sprayer tank with paint up to the manufacturer’s recommended level, as shown in the manual.

Set the sprayer pressure to an initially low-pressure level by adjusting the pressure control knob and apply paint over the painting surface in a continuous sweeping motion.

Overlap the spray layers by sweeping the sprayer tip over the edge of the previous spray layer until you attain a smooth even finish. Allow the paint to dry completely to finish.


For best results, keep your airless sprayer at a constant distance of about 12 inches from the painting surface.
