How to paint walls (A DIY guide)

Painting walls is a common and affordable way to refresh the look of your home or a particular room. It is a simple DIY project that anyone can undertake with the right tools and techniques. However, painting walls is not just about picking a color and applying it to the walls. There are several steps to consider before, during, and after painting to ensure that the outcome is perfect. In this article, we will discuss the steps to paint walls, including preparation, materials, and techniques.


Before starting to paint the walls, it is crucial to prepare the space properly. Here are some of the essential preparation steps:

  • Clear the room: Remove all furniture and other objects from the room. If you cannot remove the furniture, cover it with a plastic sheet or drop cloth to protect it from paint drips and spills.
  • Protect floors: Cover the floors with a drop cloth or plastic sheet to prevent paint drips and spills from staining the floor.
  • Clean the walls: Clean the walls thoroughly to remove any dust, dirt, or grime. Use a solution of warm water and mild detergent, and then rinse the walls with clean water. Allow the walls to dry completely before painting.
  • Repair wall damages: Fill any holes, cracks, or gaps in the walls with spackle or putty. Once the spackle is dry, sand it lightly to make the wall surface smooth.
  • Tape edges and trim: Use painter’s tape to cover the edges and trim of the walls, including the baseboards, ceiling, and window frames. This will prevent paint from getting on these areas.


Choosing the right painting materials is essential to achieve a perfect finish. Here are the materials you will need:

  • Paint: Choose the paint color and finish that you prefer. There are different types of paint finishes, including flat, eggshell, satin, semi-gloss, and high-gloss. The finish determines the amount of shine the paint will have, and the type of surface it is suitable for.
  • Paintbrushes and rollers: Use a paintbrush to paint edges, corners, and smaller areas, and a roller to paint larger areas. Choose brushes and rollers that are suitable for the type of paint you are using.
  • Paint tray: Pour the paint into a paint tray to make it easier to dip the roller and brush.
  • Drop cloths or plastic sheets: Protect the floors and furniture with a drop cloth or plastic sheet.
  • Painter’s tape: Use painter’s tape to cover edges and trim.


Here are some techniques to help you paint the walls effectively:

  • Cut in the edges: Use a paintbrush to paint the edges and corners of the walls. This will make it easier to apply the paint with a roller and prevent the paint from getting on the edges and trim.
  • Roll the paint: Use a roller to apply the paint to the walls. Start at the top of the wall and roll the paint down in a “W” shape. This will help to distribute the paint evenly and prevent roller marks.
  • Work in sections: Divide the walls into sections and paint one section at a time. This will prevent the paint from drying before you have finished painting the entire wall.
  • Apply two coats: Apply a second coat of paint after the first coat has dried completely. This will ensure that the color is even and that the paint is durable.

What to after painting walls?

After painting walls, you should take a few steps to ensure that the paint job lasts as long as possible and looks great:

  • Allow the paint to dry completely: The drying time for paint can vary depending on the type of paint used, the temperature, and the humidity levels. It’s best to wait at least 24 hours before touching the painted surface.
  • Remove painter’s tape: If you used painter’s tape to protect any areas, remove it carefully before the paint is completely dry. This will help prevent the tape from pulling off any paint or leaving a residue.
  • Clean up the area: Clean up any paint drips or spills and put away all painting supplies.
  • Inspect the paint job: Check for any missed spots or areas that may need touch-up paint.
  • Reinstall any hardware or fixtures: If you removed any hardware or fixtures before painting, reinstall them after the paint has dried completely.
  • Allow for ventilation: Open windows and doors to allow for proper ventilation and to help the paint dry faster.

By following these steps, you can ensure that your paint job looks great and lasts for a long time.
