Whether you go soft and neutral or bright and bold, the key to getting great results is to properly prepare your walls before you start painting. Below is a complete how-to guide for beginners on getting a room ready for fresh paint.

  1. Create a clean surface. Dust and dirt naturally accumulate on walls over time. Before you apply a coat of paint, it is important to thoroughly clean the surface so that the paint goes on smoothly. Try using a floor duster to clean your walls. The long handle on the duster makes it easy to reach all of the corners of the room without having to bend or stretch. For any stuck-on dirt, grime, or food particles, reach for a damp rag instead.
  1. Repair cracks, dents, and holes. As you clean your walls, keep your eyes open for any areas that need to be repaired. Holes left behind by picture hangers should be filled with wood filler. Cracks and indentations can generally be filled with spackle. Use a putty knife to apply a layer of spackle over the damaged area. Once the surface has dried completely, sand it smooth using fine-grit sandpaper. A sanding block is ideal for holding the sandpaper flat against the wall so you get a smooth, even surface. Remember to use a tack cloth or damp rag to remove the sanding dust when you are done.
  1. Mask off the edges of the room. Using painter’s tape, create a clean line along all of the edges of the room. Don’t forget to go around doors and windows as well. Taping is easiest if you work in small sections. Begin by tearing off a piece of tape about the length of your arm. Apply it to the wall in a straight line, making sure to put it on the side where you don’t want the paint to go. Use a dull object such as your fingernail or the end of a pen to press firmly down on the edge of the tape, making sure that it is securely stuck to the surface so that no paint can seep underneath it.
  1. Apply primer. Begin by cutting in the edges of the room with primer. In essence, this means using a paintbrush to manually apply primer along all of the edges of the room and around the windows and doors. Next, use a paint roller to cover the rest of the walls with primer. Allow the primer to dry thoroughly before you begin painting.

Although preparing the walls before painting can be extremely time-consuming, it is absolutely essential. If you try to skip over the prep work and just go right to painting, your results will be subpar. Only by thoroughly cleaning the walls, repairing any damage, taping off the edges, and priming the surface can you get professional-quality results that you can be proud of.
