A Guide to Prepping Walls for Interior Painting

When it comes to interior painting of walls you need to prep the walls for the paint. We have made a guide for prepping walls for you to follow in order to get the best possible finish on the walls that you can.

When you are going to paint interior walls it is best to remove all furniture that can be moved out of the room and move the rest to center of the room to be covered with drop clothes.

Have all your supplies ready and handy; brushes, rollers, gloves, face mask, safety goggles, extension for roller, paint trays, opener for paint can, stir sticks, painters tape, primer and drop cloths. Wear old clothes in case they get paint or repair product like filler on them.

  1. Dust and clean walls, normally a cloth or vacuum will work for this unless you are doing kitchen walls. While dusting and cleaning walls inspect for areas that need to be fixed such as nail holes, seams showing, flaking paint.
  2. For any flaking paint, scrape away the peeling paint. For bumpy areas, use sandpaper on a block to sand them down even, after sanding remove dust again with cloth or vacuum. For nail holes you can fill them with plastic wood filler if they are larger nail holes.
  3. Tape baseboards, window frames, and molding, if you have any wall scones or cannot remove the face plates of the outlets and switches tape the also.
  4. Apply primer to walls, especially if it is fresh sheetrock. If has a darker colour and the colour you are painting is lighter. Using a primer also hides minor imperfections. Use water based primary for minor imperfections or new sheetrock and oil based primer if there has been damage made from a fire leaving water or heavy smoke damage behind. Allow for the primer to dry according to instructions on the primer can.
  5. Start near the ceiling in one corner and work your way around the room back to where you started. With an angle brush go along molding and into the corner where you will go down the wall so far, as well as any windows or other items on the walls where you can’t get with a roller without over painting. Then use the roller to apply paint on the wall starting from the ceiling working down and feathering paint on to the areas you painted with the angle brush.
  6. If you take a break before you finish the walls in the room wrap brushes or rollers in plastic wrap to keep them from drying out and help them keep their shape. Also remember to stir the paint again before replenishing paint trays.
  7. When it comes to rollers in the corner areas, near molding, or window frames you may wish to use a mini roller which will give you more control of where the roller is going and how close it gets to areas you do not wish to have paint on.
