How to Clean Walls Before Painting

Whether you’re planning to give your living room a fresh coat of paint or embarking on a full-scale renovation project, proper wall preparation is key to achieving a smooth, long-lasting finish. Cleaning the walls before painting not only helps remove dirt, grime, and grease but also ensures that the paint adheres properly and looks its best. In this comprehensive guide, we’ll walk you through the essential steps to clean your walls effectively and prepare them for a flawless paint job.

Step one

Gather the Necessary Supplies

Before you begin cleaning your walls, gather the following supplies:

• Drop cloths or plastic sheets
• Ladder or step stool
• Soft-bristle brush or broom
• Vacuum cleaner with brush attachment
• Clean sponge or cloth
• Mild detergent or wall cleaner
• Bucket
• Warm water
• Painter’s tape

Step two

Protect the Surrounding Areas

Cover the floor with drop cloths or plastic sheets to catch any drips or debris. If there are items on the walls, such as light fixtures or artwork, remove them or cover them with plastic and secure them with painter’s tape to protect them from any cleaning solution or paint splatters.

Move your furniture

Take any furniture that is near a wall and move it in to the center of the room or into another room of your house. If you’re leaving it in the room being painted, it is best to cover it with plastic just in case.

Step three

Remove Dust and Cobwebs

Begin by removing any loose dust, cobwebs, or surface dirt from the walls. Use a soft-bristle brush or broom to gently sweep the walls. Alternatively, you can use a vacuum cleaner with a brush attachment to remove more stubborn dusty areas or to avoid a mess.

Make sure you carefully check the upper most corners of your room as this is typically where dust and cobweb buildup is the worst.

Step four

Spot Clean Stains and Marks

Inspect the walls for any stains, smudges, or marks. Mix a mild detergent or wall cleaner with warm water in a bucket according to the manufacturer’s instructions. Dip a clean sponge or cloth into the solution and gently scrub the stained areas. Avoid using abrasive materials or harsh chemicals that can damage the paint or the wall surface. Rinse the sponge or cloth frequently and change the water if it becomes dirty.

Slow and steady is the best method here. Don’t push too hard while cleaning or you may damage the existing paint on your wall. This can create an uneven coat for your new paint.

Step five

Address Grease and Stubborn Stains

For grease or stubborn stains that resist regular cleaning, use a more potent cleaning solution. You can try a mixture of warm water and vinegar or use a commercial degreaser. Apply the solution to a sponge or cloth and gently scrub the affected areas. Be sure to rinse thoroughly with clean water to remove any residue.

Step six

Clean Baseboards and Trim

Don’t forget to clean the baseboards and trim as well. Wipe them down with a damp cloth or sponge to remove any accumulated dust or dirt.

You want to see what the trim looks like fully cleaned before applying the new paint. This will create a seamless, completely-new look for your room once everything is done.

Step seven

Rinse the Walls

Once you’ve cleaned the entire wall surface, rinse it thoroughly with clean water. Use a clean sponge or cloth dampened with water to remove any remaining cleaning solution. Give it a few hours to make sure the walls are completely dry before proceeding to the next step.

Step eight

Inspect and Repair

After the walls have dried, inspect them for any imperfections, cracks, or holes. Repair these issues using with spackle, following the manufacturer’s instructions. Allow the compound to dry completely and sand it smooth for a seamless finish.
