Painting Over Old Exterior Paint: Is it Advisable?

Painting your property’s exterior is one of the best ways to increase curb appeal. However, you must decide what to do with the existing paintwork.

Is painting over old exterior paint advisable? It depends.

Painting Over Old Exterior Paint: How to Decide

You should only paint over old exterior paint if it’s not loose and flaking. Otherwise, you’ll end up with a shoddy paint job since the new  paint won’t stick to the surface.

Use the paint adhesion test if you’re unsure about the state of the paint on your exterior wall.

Here’s how to carry out the test:

  1. Cut a small X into the surface with a sharp blade
  2. Cut out some sticky tape
  3. Press it firmly across the marked surface
  4. Rip off the tape
  5. Check the results

Painting over old exterior paint is not a good idea if the old paint comes off with the sticky tape. Be sure to test different parts of the wall for best results.

Old and flaking paint shouldn’t stop you from giving your property a new look. You can still complete the painting, but it requires  an extra step.

How to Paint Over Exterior Wall with Old and Flaking Paint

Prepare the Work Area

The first step to painting is to clear the area. Remove any furniture or exterior fixtures to avoid getting paint stains on them. Protect the floor around the area with canvas sheets and tape over any sockets, handles, etc.

Scrape Off the Flaking Paint

If you’re in any doubts about the durability of your old exterior paint, get a scraper and get to work. It’s better to scrape off old paint unnecessarily than to make the mistake of painting over peeling paint.

This extra step will increase your project timeline by a few hours, but it will also save you many hours in repeat work!

Fill Out Holes and Cracks

Filling any cracks on the surface will give a smooth look after the project. Use some putty and a filling knife to cover up all holes. Areas with deeper holes may require multiple applications.

Sand down the filled areas to get a flat surface.

Clean the Surface

Vacuum up any debris and wipe down the surface with a cloth and some detergent to remove dirt and grease. Complete the cleaning process by wiping with clean water.

Use a Primer

A primer will increase the paint retaining capacity of your surface. It’s even more important if there’s no flaking and you intend to paint over old paint.

Old dark colors on previously painted surfaces may ruin the appearance of lighter colors, forcing you to apply multiple coats of the new color. A primer prevents this problem by covering up the old color.

Apply Your New Paint

Apply two coats of the new paint. Wait for a layer to dry thoroughly before applying another.

Cleaning Painted Walls: Best Methods

Contact our painting experts in Tucson by calling 520-327-3200.

Freshly painted walls can make the difference between a boring interior and exterior design and a stylish design that catches people’s eyes. 

Unfortunately, most people do not invest in cleaning painted walls. On average, you should clean your walls at least once a year. 

With over 65 years in Arizona, Wiese Painting Contractors Inc. has the experience to handle any painting job you put in front of us. We run a smooth operation that makes your home feel refreshed and stylish. Whether you own a commercial or residential property, our licensed and insured contractors are here for you. 

Here are some of the best methods for cleaning painted walls. 

Preparation 

Before you begin the cleaning process, you must rid your walls of dust or debris. You can dust the walls with a cloth, vacuum, or brush to prepare for cleaning. 

We recommend a foam craft brush for getting into corners and around edges. Also, make sure that you place a towel below the walls you plan to clean. Drips and spills are common when cleaning painted walls. 

Select a Cleaning Solution 

Next, you must select a cleaning solution to remove dirt from your walls. Your choice should center around what kind of paint you have on your walls. 

For matte, eggshell, or flat paint, you should use a mild cleaning solution. To create a mild wall cleaner, you can combine dye-free soap with dishwashing detergent. 

If you have a glossy paint finish, we recommend using a degreasing agent with your cleaner. These finishes are more durable than matte or eggshell coats, allowing you to use a stronger soap in your cleanser. 

If the paint job on your walls is oil-based, you may use an even stronger cleanser. A popular recipe for an oil-based cleaner is to mix a teaspoon of liquid dish soap with a tiny amount of ammonia. 

Washing 

When you wash your walls, you want to do it gently. If you are too abrasive, the paint will chip or peel off. Make sure you use the soft side of the scrub to rub the cleaning solution onto your walls. 

To achieve the best results, clean the wall in circular motions and work from the top down. Be careful to keep water away from electrical outlets to prevent dangerous sparks and electrical issues. 

If your regular cleaning solution did not do the trick, try spot-treating the walls using a mixture of baking soda and water. 

Drying 

If your sponge did not absorb all the water from your washing session, you should use a dry towel to mop up any extra liquid from your walls. Wait for your wall to dry before hanging pictures back up.
