1. One common mistake that you will want to avoid is rushing the preparation process for the room or rooms that you will be painting. Chances are you will have to do more than just paint, so take your time with doing things like filling in all the cracks and holes in the wall. You will want to be as thorough as possible, so give yourself at least a few days before you get down to the actual painting part.
2. If your walls are damaged in any way, you will not want to try painting over them. This is another common mistake that people make when painting a room in their home. Fixing the holes and cracks in your walls is an essential aspect of painting a room. There are kits that you can buy that are meant specifically for people who want to fill in the holes in their drywall. You can get them at your local hardware store for a very minimal cost.
3. If you really want the color on your walls to shine and look professional, then you will certainly want to put a layer of primer on before you begin painting. Sometimes a primer is required for walls that have colors which are especially bright, such as hot pink for a girls room. Make sure that when you are putting the primer on, you do a thorough job and cover all the corners. Not doing so could mean having to touch it up again and take even more time out of your day.
