• One room or the whole house? Applying one coat in one room is a reasonable DIY Saturday project (especially if you have help and beer). Multiply the time spent moving furniture, prepping walls and sanding old trim by the number of rooms in the house, and you might want to hire real help. It's the same outside. You can probably tackle one shady garage wall that needs a little scraping and sanding plus a coat of paint, but covering all surfaces of the house is usually best left to a pro.
Painting is one of the quickest and easiest ways to give your home's interior a facelift -- and it is one that can produce dramatic results as well. Unfortunately, many homeowners feel overwhelmed when tasked with choosing a lasting color scheme. To avoid getting stuck with a less-than-perfect color choice, they will spend hours studying the subtleties between Smokey Topaz and Roycroft Suede paint swatches, considering the mood they want to create (whimsical? relaxing? modern edge?), and deciding whether to trust their guts or hire an interior decorator to make sure things turn out just right. Fortunately, interior painting doesn't have to be that difficult. Most paint stores offer samples that you can take home for a wall test. With these samples, you can paint a few colors in large swaths on your wall to see the how the paint interacts with the room's natural light. And you can compare it against design elements like pillows or furniture to see whether it will work with your overall decor as well.
Thorough preparation is essential to ensure a good finish. Contractors might have to fill cracks or holes and remove old paint if it is badly worn, peeling or flaking. They remove all paint and apply a suitable primer to the bare surface. If the existing paint is in reasonable condition, they clean it and rub it with abrasive material to provide a key for the new paint. On new surfaces, such as bare wood or fresh plaster, they apply a suitable seal, followed by a primer coat.
