Spray painting is a great way to paint large surface areas quickly. It requires very little time and effort and gives professional results if you use high quality equipment. Proper preparation of the surface is very important for a good paint job.

Step 1 – Remove All Furniture and Fixtures

The process of spray painting involves covering surfaces with a jet of paint from a sprayer. This jet consists of extremely minute paint particles that can travel long distances and settle on objects. To prevent paint flecks from landing on other objects in the room, you must remove or properly cover everything. It is best to remove all fixtures from the wall and take them outside. Small pieces of furniture can also be moved out. Anything that remains in the room must be covered with drop cloths. You can either remove the switch plates or cover them with masking tape.

Step 2 – Cover the Floor and Permanent Fixtures

Some of the accessories or fixtures in a room cannot be removed and taken out. Some examples are window frames, fireplaces, countertops and cabinets. All these must be properly covered with drop cloths that are securely taped in place. With proper preparation, you can avoid a lot of time and effort in cleaning up after. If you are painting the ceiling as well, you must cover the walls with masking tape.

Step 3 – Ensure an Even Finish

Most walls have small dents or holes left behind by fixtures. If you plan to hang the fixture back in the same spot after painting, there is no need to seal the hole. Otherwise, you must use spackle and a putty knife to fill the holes properly. Once the holes are filled, scrape off any excess. Let the spackle dry for at least 24 hours and then use sandpaper to sand the area. Sand the sealed area gently but thoroughly to get a smooth finish. Ensure that you have covered all the flaws and imperfections on the wall. If you are painting over a glossy finish, you must use a deglosser or sandpaper to remove the gloss.

Step 4 – Clean the Wall

Before painting, it is essential to clean the wall thoroughly. Any grime or grease on the wall will lessen the adherence of the paint and reduce the quality of the finish. Use mild soap and water to make a solution and scrub the walls with it. Remove any residue with a sponge. Let the walls dry properly before you start painting.

Step 5 – Apply Primer

First ensure that your spraying can or gun is completely clean and free of any paint residue. Then fill the container with primer and spray it on the clean, dry walls. To avoid over spray and unevenness, spray in light, even coats. Never stop moving your hand as you spray.
