You can learn all about how to prepare a room for painting. These steps can make the process of painting and cleaning up easier. One nifty tip is to remove outlet covers, light switch plates, thermostats, and anything that is on your walls. Put anything with screws in a plastic bag so nothing gets lost or separated.
When learning how to paint a wall you’ll also need to know how to apply primer. Use a brush to get corners, crevices, and other hard to reach places. Use long, continuous strokes and then smooth it out by brushing in multiple directions. Wait for it to dry. Painting over wet primer can cause smudging, which means repainting.
You can use self-priming paint if you want to skip this step, but it may not be the best idea for your walls. Separate primer tends to hold up better.
As for the brushing technique, we like to dip our brushes about 2 inches into the paint and let the extra drip off. We then brush around the edges, making sure to brush out the paint so there is no chance of runs.
