If you are considering painting the rooms throughout your house or want to hire a professional to do so, it is important to ensure that your walls are clean first. The walls throughout your home can become covered with dust, dirt, oil, grease, and other substances over time. Each of these substances can negatively impact your painting project as they can prevent paint from properly sticking. As leading providers of complete interior painting services, the team at Dunbar Painting knows how important proper preparation is for every project. That is why we have provided some information to demonstrate why it is important to clean your walls before painting as part of your prep work.

3 Reasons Why You Need to Clean Your Walls Before Painting

Your walls need to be painted before applying paint for the following reasons:

1. Paint Does Not Stick to Dirt, Oil, or Grease

Paint will not stick to your walls if they are covered in dirt, dust, or other substances even if you are using high-quality products. Before applying paint to your walls, you will need to wipe them down with a microfibre cloth or use a vacuum to remove dust. Next, use a non-abrasive wet sponge to wash your walls to remove dirt, oil, and other substances. Once this is done, use a towel to remove any excess moisture. Once dry, your walls are ready to be painted. Thoroughly cleaning your walls will help to ensure a more consistent and longer-lasting finish, making it well worth the effort.

2. Failure to Clean can Lead to Problems in the Future

If you choose to skip cleaning, you will likely end up experiencing several issues with paint coverage, consistency, and quality throughout your project. Painting over dust, dirt, oil, and chemical products can also lead to the formation of mold and mildew, requiring you to treat the wall, clean it, and paint it again. While cleaning does require time to complete, it will save you time and effort in the future.

3. Certain Rooms Will Have More Dirt/Grease Than Others

Bathrooms and kitchens are more prone to grease buildup and exposure to chemicals like hair products and aerosols. Each of these substances can accumulate on walls over time, forming a layer that may not be noticeable at first glance. To ensure that paint properly sticks to these walls, they will need to be thoroughly cleaned and degreased.
