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:

  • 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.

Frequently Asked Questions

Yes, painting over old paint requires sanding with a fine-grit sandpaper to even out the surface. Sanding makes the surface even enough for proper paint adhesion.

Yes, you can paint over glossy or semi-gloss paint. But for the best adhesion, we recommend thoroughly cleaning the surface and sanding it to remove the shine before painting. Primer also helps even out the surface, improving paint adhesion and color appeal.

You can tell if old paint is oil-based or latex by conducting a small test. Rub a cotton ball with rubbing alcohol or acetone on the painted surface. If the paint comes off, it’s latex, but if it stays put, it’s oil-based.

No, it is not recommended to paint directly over old peeling paint. It’s important to scrape the peeling paint, sand the surface, and apply primer before painting.

No, it is not safe to paint over lead-based paint. If your home may have lead-based paint, it’s crucial that you call professionals to deal with it safely.

Generally, you’ll want to sand and prime the surface and then apply at least two coats of paint. However, the exact number of coats depends on the type of paint, the color of the old paint, the color of your new paint, and the condition of the wall.

Yes, an old paint color can show through if you skip the primer, especially if you are changing from a dark color to a light color or painting on glossy surfaces. Primer or additional coats of paint would be recommended.

We had a great experience with Paint Boise. They were very responsive and came out quickly to provide an estimate. We walked the fence and pergola together and had a detailed discussion about stain options, including oil versus water based, as well as the level of prep work required. The estimate clearly reflected those discussions.After the first day, there was a small disconnect as the fence did not look pressure washed as expected. I reached out to Toby, and he showed up the next morning without hesitation to walk the project with me. I shared photos, he agreed with the concern, and he personally took ownership of it by pressure washing the fence that same day to my full satisfaction.Beyond that, the team repaired several sections of the fence and a gate, and the end result looks like new.Both the fence and the pergola are in good position to last at least another 5 years with this fresh coat.The price was on the higher side, but the quality of service, accountability, and the warranty made it well worth it. Overall, a professional team that stands behind their work.

I used 16 colors on my inside walls — all clean lines where colors meet, painted switch plates/socket covers to match background (even painted covers for all-house vacumn system)Well managed, professional, quality checks and emphasis on complete customer satisfaction.Recommended without reservation. Hard to imagine there is a better choice.
I obtained bids from 6 painting contractors last fall (2025) to paint our stucco home including fascia, garage doors, and stain the wood pergola over the double garage door. It was a big project and I sweated all winter giving the go ahead to Collin at Boise Commercial and Residential Painting to begin in May '26. NO down payment, no cancelation penalty, and no payment until satisfied. Incredible! A man of his word, Collin met every expectation. His crew were excellent, motivated, polite and responsive. My wife and I could not have been more pleased with the end product and great service and communication Collin provided throughout the project. Why did I sweat this contract all winter when Collin made the whole project painless. My recommendation...if you are looking for a painting contractor...speak to Collin. 100% thumbs up. H
I recently had the pleasure of working with Boise commercial paint and I couldn't be happier with the overall experience. I was looking to have the exterior of my house painted and I had shopped around and all bids seemed so high, until I met Toby and Collin. They came to check out the house...asked questions on what we wanted and were very thorough with their inspection. When we got the quote I was shocked and delighted at how reasonable they were!When Elmer and his crew arrived the day of, they were all very professional and so kind...and always happy to chat. They really did go above and beyond and paid close attention to details...such an amazing crew!Toby oversaw the job and was always checking in..or on site...I had a hard time picking colors and he was very patient with me, so much so he let me use his new car to go look at more colors! Outstanding customer service!!Overall I am extremely happy with our choice to go with Boise commercial paint. I will absolutely be recommending them to clients and friends, and will be hiring them again in the future for interior projects.Thank to all the crew, and everyone involved in our project for all your hard work! You truly are appreciated.
We just had the exterior of our house painted by Paint Boise, and we couldn’t be happier! From start to finish, their communication was great, and they really paid attention to every little detail. The team was professional, friendly, and clearly cared about doing the job right.We were so impressed that we were already recommending them to friends before the job was even finished. Truly a 5-star experience!
I am a person who will do small projects on my own but I knew painting the edges would get the best of me in the guest bathroom. So. Many. Edges.When I saw other great reviews and the satisfaction guarantee, I was instantly comfortable with my choice of painters. They kindly worked with my budget, which I greatly appreciated.Toby and Collin did a beautiful job on our guest bathroom! The vibrant peach color sure stands out and they applied it expertly, made sure the touch ups were clean, and let me look over their work before they finished.They took care to keep our home protected and clean with protective draping over the floors and appliances as well as carpet protection just outside the bathroom door. One of them even used a coaster for his coffee thermos without even needing me to ask. True professionalism! They also wore booties over their shoes to keep our carpets free from debris.I felt comfortable with Toby and Collin and really appreciated their friendly demeanors, their joviality, their hard work, their willingness to allow me to point out little spots during the touch-up review (that peach does kind of blind you after a while) and their dedication to their work.If I need help with painting in the future, I’ll be giving them another call! And I’ll be telling all my friends about the wonderful work they did!
Definitely recommend, great communication, they were quick to come and give a quote. Always showed up on time and finished the job sooner than expected. We were very pleased with the results.
