Ready Your Walls for Painting: Removing Coverings

Step 1: Remove Existing Wall Coverings

Before you begin the process of painting your walls, it is essential to remove any existing wallpaper, borders, or other coverings.

Not only will this make the process easier, but it will also ensure that the paint adheres properly to the walls and provides a clean, professional finish.

To remove wallpaper, you can either use a wallpaper steamer or a wallpaper stripping solution. Both methods are quite effective; however, a steamer might be a better option if you’re dealing with older adhesives.

Step 2: Repair any Damages

After removing wall coverings, inspect the walls for any damages, such as cracks, holes, or dents. If you find any damages, it is crucial to repair them before painting to achieve a smooth, even finish.

Small cracks and holes can be easily repaired with patching compound or spackle. Apply the compound using a putty knife and allow it to dry completely before moving on to the next step.

For larger holes or damage, it may be necessary to cut out the damaged area and install a patch of the same material before filling any gaps with the compound. Always be sure to follow the manufacturer’s instructions for best results.

Step 3: Clean the Walls

Once the repairs are complete, it’s time to clean the walls. This step is crucial to ensure that the new paint adheres properly and appears smooth and even.

Use a clean sponge and mild, soapy water to wipe down the walls, removing any dust, dirt, or debris that may have accumulated during the removal and repair process.

If there is any remaining wallpaper adhesive residue on the walls, use a wallpaper adhesive remover to eliminate it. You can also use fine-grit sandpaper to gently sand the walls, which will help remove any remaining residue and create a slightly rough surface for the paint to adhere to.

Step 4: Prime the Walls

Priming is an essential step in preparing walls for painting, as it ensures proper paint adhesion, coverage, and durability. Use a quality primer specifically designed for interior walls, following the manufacturer’s instructions for application.

When choosing a primer, consider the type of paint you plan to use and the color you’ve selected. For example, if you’re using latex-based paint, select a latex-based primer. Additionally, if you’re painting a dark color, choose a tinted primer to help achieve better coverage with fewer coats of paint.

Step 5: Mask Off Adjacent Surfaces

To ensure clean edges and protect neighboring surfaces, use painter’s tape to mask off baseboards, crown molding, door and window frames, and any other areas that should remain paint-free. Press the tape firmly against the surface to create a secure seal and prevent paint from seeping underneath.

Step 6: Cut in and Paint

Now that your walls are adequately prepared, it’s time to begin the painting process. Start by “cutting in” the edges and corners of the walls using a smaller, angled brush.

This technique involves painting a narrow strip along the edges and corners, ensuring a clean finish that the roller may not be able to reach.

Once the edges and corners have been cut in, use a paint roller to apply the paint to the walls in smooth, even strokes.

Depending on the paint’s color and type, it may be necessary to apply multiple coats to achieve full coverage. Be sure to allow each coat of paint to dry thoroughly before applying additional coats.


By following these steps for preparing walls for painting, you’ll ensure a beautiful, long-lasting finish that transforms your space.

The key is to take the time needed to properly remove wall coverings, repair any damages, clean the walls, and prime the surface. With proper preparation, your walls will be ready for a fresh new coat of paint that lasts for years to come.

Expert Wall Preparation Techniques Used by Painters

Preparing walls for painting is a crucial step that ensures the durability and attractiveness of the paint job. Professional painters ensure that the walls are clean, even, and well-prepared to achieve the best possible results.

Assessing the Wall Condition

The first step in wall preparation is to assess the condition of the walls. Professional painters look for any damage, like cracks, holes, water damage, or mold. If required, they tackle these issues before initiating the painting process.

They fill the cracks with a joint compound, and if there is extensive damage, they might suggest replacing a section of the drywall or applying a plaster coat.

Cleaning the Walls

Ensuring the walls are clean is vital for the paint to adhere properly. Professional painters start by removing dirt, dust, grease, and other types of grime using a warm water and soap solution.

They might also use a degreasing agent if there is any heavy grease present on the walls. In the case of mold, they use a bleach and water solution to kill the mold spores and prevent further growth.

It is essential to pay attention to any loose paint and remove it using a scraper before beginning the cleaning process. Once the walls have been cleaned and treated for mold, professional painters let them dry thoroughly before proceeding to the next step.

Sanding the Walls

To create an even and smooth surface, professional painters sand the walls. They use sandpaper, usually in the range of 120 to 150 grit, and sand the entire wall surface.

Sanding helps remove any imperfections, rough spots, and uneven areas, ensuring the paint will adhere uniformly.

During the sanding process, professionals also focus on areas where the joint compound has been applied to mend cracks or fill holes.

They sand these areas to ensure that they are flush with the rest of the wall surface. After sanding, use a cloth or vacuum to remove any dust from the walls.

Applying Primer

Priming is a fundamental part of the wall preparation process. Professional painters apply a coat of primer to seal the surface and create a consistent base for the paint to adhere to. Priming also helps in bringing out the true color of the paint and enhances its durability.

There are different types of primers available, and professional painters choose the suitable one depending on the wall surface and the type of paint being used. Some of the common types of primers include oil-based, latex-based, and shellac-based primers.

Pro Tip: If you’re painting over a dark color or the wall has significant stains, consider using a high-hide or stain-blocking primer to ensure even and uniform coverage of the topcoat.

Taping and Protecting Adjacent Areas

Before starting the painting process, professional painters take measures to protect adjacent areas from paint splatters and drips.

They use painter’s tape to mask off baseboards, trim, windows, and other surfaces that are not to be painted. The tape should be applied carefully, ensuring a firm seal along the edges to prevent paint from seeping underneath.

In addition to taping, drop cloths, plastic sheets, or masking paper are placed on the floor and other surfaces, like furniture, to protect them from paint drips and splatters.

Preparing the Paint

Once the walls are prepped and the adjacent areas are protected, professional painters prepare the paint. They begin by stirring the paint well to ensure uniformity in color and consistency.

If more than one can of paint is being used, professionals often mix the cans to maintain color consistency throughout the project.

Recommendation: If you’re using paint that has been stored for a while, consider straining it through a paint strainer to remove any solid particles or lumps before application.

Following these essential steps, professionals can now proceed with applying the paint, confident in the knowledge that the well-prepared wall surface will result in a flawless and long-lasting paint job.

Following these steps in your DIY painting projects can significantly enhance the final outcome and give you a professional-quality result.
