Properly preparing your walls for painting is a crucial undertaking in attaining a polished and professional appearance. By dedicating time to the meticulous preparation of your walls, you create an optimal surface for paint adhesion, resulting in a flawlessly smooth finish.

Getting the job done requires knowing the right painting techniques and tools such as a ladder, brushes, tape, and sandpaper. 

Here are steps to walk you through the process of preparing walls for painting to get a beautiful and long-lasting finish. 

Wall Preparation Before Painting

Proper wall preparation is crucial to achieving a flawless and professional-looking paint job. 

Before picking up a brush, here’s how to prepare the different types of walls. 

Prepping Drywall for Paint

For optimal results when painting drywall, there are essential steps to take. Prepping drywall for paint is simple but very intuitive. 

Here are the simple steps to make the process easier for you:

  1. Check for any gouges or dings in the wall. If you find any, fill them using drywall mud or other paste solution. 
  2. Sand the wall using a pole sander to smoothen the surface.
  3. Remove dust from the wall using a suction attachment on the vacuum. Then, run a black towel over the wall to eliminate any remaining dust before vacuuming again.
  4. Mix a cup of white vinegar with a gallon of water in a bucket and use a sponge to wash the wall using the mixture. 
  5. Sit a fan against the wet wall to dry before painting.
  6. Start painting when the wall is dry.

Apply primer on the wall for the paint to go on smoothly and to adhere properly. Latex-based primer is a better choice to give the wall a polished look and to protect it from dings and small knicks. 

Preparing Old Walls for Painting

Old walls accumulate dirt, grime, and imperfections that need addressing to ensure a smooth and professional finish. 

Here are steps to preparing old walls for painting:

  1. Thoroughly clean the walls to remove dirt, grime, and grease using mild detergent, water, and a sponge or cloth.
  2. Check for loose or flaking paint and peel it away using a scraper or putty knife. 
  3. Fill any cracks or small holes using patching material and let it dry properly.
  4. Smooth out any texture using the skim coating.
  5. Apply a coat of primer evenly and let it dry properly.
  6. Sand the walls using fine-grit sandpaper to eliminate any remaining imperfections. 
  7. protect adjacent surfaces using painter’s tape or cloth before painting. 

Preparing Plaster for Painting

Painting new plaster is not the same as dealing with ordinary walls. You need more preparation and patience. 

Here are the steps to preparing plaster for painting:

  1. Let the plaster dry properly for a more even finish, or the paint will crack and peel off.
  2. Create mist coat paint to act as a primer and prevent uneven brush strokes. 
  3. Sand or fill any flaws on the wall before applying mist coat paint. 
  4. Add a top coat to give the wall a splash of color. 

Painting Bathroom Walls

A fresh coat of paint refreshes the look and feel of a bathroom. However, special consideration is crucial before painting bathroom walls because of the unique condition and moisture.

  • Use sandpaper to remove flaking or peeling paint to get a smooth surface.
  • Put masking tape around fixtures such as taps and tiles. 
  • Cut in around the walls and edges using a paintbrush.
  • Apply paint evenly using a roller. Work in “W” sections when applying the first coat.
  • Leave the paint to dry before applying a second coat and removing the masking tape.
