How To Paint Trim With Sprayer?

Step 1: Spray Your Uninstalled Trim 

Before installing, trim painting is straightforward. So, if you haven’t installed trim yet, that’s a good thing for you. You can easily paint your uninstalled trim.

Since your trim is still not installed, you will not need to cover your wall to protect it from paint splatters before painting. You simply lay your trim horizontally on a pair of sawhorses and spray paint over it. When the trim is dry, install it.

Step 2: Repair Any Holes 

You will need to go to the next step if your trim has already been installed. With wood putty, fill any holes first.

Give wood putty the suggested amount of time to dry. You also have the option of a Wagner heat gun, which you can use to repair the hole.

Step 3: Sand Your Trim 

When the wood putty appears to be fully dry, use medium-grit sandpaper to remove any debris from the clogged nail holes.

After that, use sandpaper to eliminate any shine from the remaining trim. Doing so will allow the fresh paint to stick snugly to your trim.

Step 4: Close The Gaps With Latex Caulking 

Dust can build up on your trim, so it’s important to wipe it off and then clean it thoroughly with a wet cloth.

If gaps remain between the wall and the trim, close them using latex caulking.

Step 5: Cover Your Wall And Floor 

Now, you are in the process of painting your trim. So for this, you have to prepare your room and the trim of the room you want to paint.

Fit the plastic sheet with painter’s tape to cover the walls and ceiling around the trim, i.e., the area you don’t want to paint.

Cover your floor and room furniture with a drop cloth so that these can be safe from paint splatters. As much as possible, shift the items from one room to another room.

Step 6: Choose Graco TrueCoat Sprayer Or Graco Magnum Sprayer For Spraying 

You can use the Graco TrueCoat paint sprayer or the Graco Magnum paint sprayer for spraying. These two sprayers are considered ideal for any painting projects, such as walls, ceilings, trim, etc.

You will be able to paint more efficiently and quickly with a sprayer than with a brush. Also, the sprayer is helpful for achieving a smooth finish.

Painting with a brush leaves a mark on the surface. But painting with a sprayer will keep you free from this concern.

Step 7: Check The Spray Pattern

Load your preferred paint shade into the material cup of your sprayer. Although white or black are considered ideal for trim, you can choose any color that suits your room.

Now, adjust the paint flow and airflow. You can use a piece of cardboard to check the spray pattern. Now, you can start the painting process.

Put on goggles to ensure eye protection. Also, wear gloves and a dust mask or respirator when painting.

Step 8: Spray The Trim

For the direction you are spraying, adjust your nozzle. Next, spray the trim from one corner to the other.

Keep the spray gun at 6/7 inches from the trim when spraying. Keep your sprayer’s tip parallel to the trim while applying the spray.

Step 9: Spray Your Trim Side To Side 

Make sure to set your nozzle so it can spray up and down.

Keep a moist cloth nearby and keep wiping the spray tip with it occasionally to prevent paint from building up on the nozzle.

You can complete the task in a single pass when painting the trim.

Step 10: Remove The Cover From Your Wall And Floor

Your small painting task is accomplished. Uncover your wall and floor by removing the plastic sheet and dropping cloth from them.

Step 11: Look At Your Transformed Room 

An extraordinary change will be seen in your room after spraying the trim. Your room will be transformed. Enjoy your room!
