How to Paint Over Old Paint

If you want to get rid of flaky, peeling, or bubbling paint, painting over it sounds like an easy enough solution, right? Unfortunately, it’s not that simple. Painting over old paint requires a specialized approach to ensure proper adhesion and a lasting finish. There are many steps involved in preparing, painting, and maintaining your newly-painted surface.

Can You Paint Over Old Paint?

You can paint over old paint, but it requires specialized techniques and a proper method. In some cases, painting over old paint is not recommended. Therefore, you have to assess your walls in great detail before determining your next step. If the paint on your walls adheres well and shows no significant peeling, you can paint over it. However, if the paint has lead, severe flaking, or moisture damage, it’s best not to paint over it until you resolve the underlying problem.

Tools and Materials You’ll Need

Before you start the process of painting over your old paint, here are a few tools and materials you should gather:

  • Paint: Make sure you have the right quality, quantity, and color of paint.
  • Drop cloths or plastic sheeting: These help you cover your floor and furniture to prevent spills and stains.
  • Putty knife and filler: These let you fill and patch holes and dents in your wall.
  • Sanding block and sandpaper: Use these to smooth patches and level the surface.
  • Painter’s tape: This protects your trim, ceilings, and fixtures.
  • Scraper: This is essential for removing peeling and flaky paint.

Painting Over Old Paint: A Step-by-Step Approach

Ready to paint over old paint and update your walls? Follow this step-by-step guide to ensure a lasting finish.

Assess the Surface Condition

The first step is assessing the surface condition. Check if your old paint is peeling or flaking; if it is, you will need to remove it before painting the walls. If you notice moisture damage or water stains, you may need to address the underlying water intrusion before repainting the surface. Any surface-level stains should be cleaned before repainting.

Prepare the Surface

The next step is preparing the surface for painting. Move furniture to create an accessible space for painting, cover fixtures, trim, and molding with painter’s tape, and cover your floor with plastic sheeting or drop cloths to prevent spills and stains. Use a paint scraper to remove any loose, peeling, or curling paint, and fill and patch holes with a filler. Before you start painting, use a fine-grit sandpaper to lightly sand glossy surfaces and patched areas, creating a grippy texture and improving paint adhesion.

Apply Primer

A primer creates a uniform, sealed surface that improves paint adhesion, color accuracy, and durability. Use a quality primer and apply a coat evenly over the surface.

Paint Over Old Paint

Once the surface is primed, it’s ready for paint. Apply at least two coats of your new paint over the surface. Let the first coat dry thoroughly before applying the second one. This will create proper adhesion and a smooth color, and prevent paint cracking and peeling.

Test and Monitor

Painting dries in a few hours, but proper curing can take a few days. That is why testing and monitoring are crucial after painting over old paint. Look for spaces that may indicate color unevenness or dents, and fix them promptly before cleaning the areas. Once the paint is cured, check its adhesion with a painter’s tape.

When to Call a Professional

You can DIY small painting projects on walls with no old paint issues easily. However, some projects require professional services. If the old coating needs more than a simple refresh, Paint Boise’s interior painting services in Boise can handle prep, primer, and finish coats for a cleaner result.

Extensive Peeling or Structural Issues

If your walls have extensive peeling or structural issues, it might be best to call for professional painting services. An expert will recommend appropriate solutions to prepare the surface and strengthen the structure before starting the painting process.

Lead Paint Removal or Encapsulation

Lead paint is incredibly harmful to health, and removing it yourself can pose great health risks. Therefore, always call professional teams for lead paint removal or encapsulation services. They can offer tailored solutions while keeping you and your home safe.

Maintenance Tips After Painting Over Old Paint

Here are a few maintenance tips to help you take care of a newly painted surface:

To understand the right timeline for refreshing your home’s interior, read our guide on how often should you paint your house for helpful scheduling advice.

  • Regular Cleaning: Regularly clean your walls with a soft, damp cloth or a microfiber towel. Only use water or water mixed with a small amount of soap, if needed, and avoid using harsh chemicals.
  • Humidity Control: Use a dehumidifier to maintain optimal humidity levels in your home. Excess humidity can lead to peeling and blistering.
  • Exterior Care: Maintain some distance between the painted surface and other objects, like furniture, to prevent abrasion. Keep plants away from the wall to avoid moisture buildup.

The work was amazing, colors perfect, and they were very professional and thorough. My house looks brand new!
Painting my house to get ready for sale. Toby was very responsive, and I felt like he really listened to what I needed. He kept me informed every step of the way and worked hard to meet my timeline. His crew was very conscientious and they got the job done to my standards. Toby went above and beyond, helped my with a couple of items that were not painting related but assisted me getting other things done. I really appreciate all that was done.
Excellent service! Collin is amazing and so easy to work with and cares that you are happy with your finished product! You don’t need to shop around just call them and you’ll see how how fast with great quality they really are!
Jennifer and her team were such a blessing! They were not only professional and extremely talented but they were so good with my fur babies!! I was SO impressed with their work from start to finish. Jennifer made me feel confident from the start. I changed the scope mid job and she was happy to accommodate, helped me find a very talented contractor for base boards, and did such a great job painting! I highly recommend them for any job!! They were stellar!
Bench Condominiums Homeowners Association – Review of Boise Commercial & Residential PaintingBoise Commercial & Residential Painting recently completed a full exterior repaint of the Bench Condominiums in Boise, Idaho, and the HOA Board is extremely pleased with the results. Our buildings, constructed in 1971, had not been painted in more than twenty years and were showing significant wear—peeling paint, wood deterioration, and rain gutter damage among other issues. This was a major project, and Collin and his crew approached it with professionalism, skill, and a clear plan from start to finish.From the initial walkthrough to the final inspection, the team demonstrated exceptional attention to detail. They took a tired, aging property and brought new life to it with a thoughtful four‑color scheme that moved the complex away from its outdated dormitory‑style appearance. The transformation has been remarkable, giving the community a refreshed, modern, and welcoming look.Working around 72 families is no small task, yet the crew handled the project with minimal inconvenience to residents. Communication was clear, disruptions were limited, and the team remained respectful of the community throughout the process.Although the project was estimated to take six weeks, Collin’s well‑organized plan and dedicated employees allowed them to complete the work in under five weeks—without sacrificing quality. The workmanship, efficiency, and professionalism exceeded expectations.The HOA Board and residents are extremely happy with the outcome, and the project was completed at a very fair price. Boise Commercial & Residential Painting delivered outstanding value and a result that will benefit the property for years to come.Highly recommended.
Good communication with Toby . The finished work was excellent and completed in a timely manner . Top quality ! I would use this crew again !
We had a really good experience with these guys. They communicated well, showed up, did good work, and we’re really happy with how everything turned out. We did have a minor issue with our drains during the project, but they went above and beyond to get it fixed and make sure we were taken care of. That meant a lot to us. They’re good painters and good people to work with. I wouldn’t hesitate to recommend them to anyone.
As a commercial construction project manager, I work with painting contractors all over the country, and Boise Residential and Commercial Painting is the kind of sub you hope to find. They handled interior office painting plus the finish work that’s easy to get wrong — customer signage trims and counter trims — and the detail work came out crisp and clean. Communication was straightforward, they showed up when they said they would, and they treated the schedule like it mattered. The finished product looks sharp in a customer-facing space. I wouldn’t hesitate to use them again or recommend them for residential or commercial work.
My Husband & I had the exterior of our home painted by Boise Commercial & Residential Painting. Collin and his crew provided an excellent product and were professional. Always on time, good communication, cleaned up well at the end of each day of our multi day project. Great Job!
We received 3 bids to paint the exterior of our home. Ultimately, we went with them because the estimator, Toby was very personable and knowledgeable about all aspects of the job. We needed siding replaced and he suggested that we install gutters in certain areas to prevent future damage. The contract was very thorough and detailed. Colin, the owner showed up multiple times during the project. Couldn’t be happier with the outcome.
