Dust and Spot Wash the Walls
Before painting, you will want to inspect the walls. Is there dust that needs to be removed? Perhaps you are painting in a kitchen where there might be grease on the walls. Take a few minutes and make sure the surface is clean before doing your prep. This is a good time to look over the walls to see if there are any repairs that need to be done with stress cracks and nail holes.
Cut in the Wall with a Brush
Before cutting in the walls with a brush, we recommend taping the trim off with Frog Tape. This will help to prevent any seepage of paint from getting on the trim. Frog tape is more expensive than other tapes, but well worth it so that there is less cleanup.
Rolling a Wall
You will want to make sure that you are starting at the top of the wall. When it comes to DIY, our Grand Rapids Painters at Hillis Brothers Painting, believe in using the "W" method. Start in the upper corner and roll out the shape of a "W", then fit in the rest by going up and down. This will help to equally distribute the paint. After the top is done, move to the section below it. After both the lower and upper are done, take the roller from top to bottom to create good lines. Move efficiently so the paint doesn't dry up too quickly.
