How-to: Paint like a Pro
It is good to start off with putting a primer on first. Primers can cover stains so when you paint they won’t show through. When painting, I paint the walls first and then the trim. I hate getting paint on the trim when I am working on the wall. If you want to do the trim first you can tape the wall surrounding it. When done, pull tape off and work on the wall. When painting the wall, paint Y’s and then fill in the remaining gap between the outline. This method ensures that the job your doing will be even and professional like. Basically you are making an outline and working from the outside in.
When blending the wall’s edge and whole perimeter go as close to the wall as you can with a roller. Then you can use a paintbrush to get what the roller can not reach. To do around windows, you can tape up the edges of the glass. Use a paint brush for this job. Do not apply a lot of paint to the paint brush because then it will just leak. When working on doors, start at the top and work your way down. Use a minimal amount of paint near the doorknob. When cleaning up, just wash the paintbrushes and rollers with warm water and some soap detergent then shake dry. Now that you read my tips, go out to your local hardware store and buy some paint and give your painting a shot!
