How Can I Fix Peeling Paint Outside?


One of the main ways to improve the look of your home is to give it a fresh lick of paint- this is especially the case if your home is suffering with peeling paint problems, which detract from the overall appeal of your property.

Even small patches of peeling paint can make your home’s exterior look tired and unkempt, and it can seem as though you haven’t taken good care of it. Peeling paint also indicates a loss of protection of the wood or masonry below and this can cause all kinds of problems.

So how do you deal with peeling paint, and what is the best way to prevent it happening in the first place? It’s time to find out…

What Causes Peeling Paint?

In almost all cases, peeling paint is due to the surface not being properly prepared. Paint needs to stick well to the surface it is painted onto, and if this adhesion doesn’t take place, it won’t be long before that paint is coming off, or at the very least, is starting to crack.

The best way to prepare the surface is to rub it down to remove the old paint, degrease the area, and to apply a primer if it is required.

For exterior walls, one of the main reasons the paint may start to peel is because of damp and moisture that is inside the walls. Unfortunately, very little will stick to a damp wall, and getting these walls dry can be a problem. Painting after rainfall is a no no, and waiting for walls to dry takes a great deal of time.


Using poor quality paint is often the reason for peeling. If the paint has been sitting around in your garage for a few years, there's a good chance it might be past its best

Why Choosing The Right Type Of Paint Is Key

Using the wrong type of paint for the area you are painting is another recipe for disaster. For example, you should use masonry paint for bricks, wood paint for wood, metal paint for downpipes etc.

If you fail to use the right paint, you can expect that it won’t adhere correctly to the surface, and you will be redoing the job before you know it.

Using poor quality or cheap/old paint can also be a reason for paint peeling. If the paint has been sitting around in your garage for a few years, there’s a good chance it might be past its best.

Equally, the paint that your local D.I.Y store is selling at half the price of everything else might work fine for a year or two, but may not have the level of longevity you’re looking for.

Finally, follow the instructions. Paint that hasn’t been mixed correctly can separate, and will crack and peel more readily that properly prepared paint.

As we can see, there are many reason why paint can crack – but if the worst has happened, what can we do to fix the paint that is peeling on the outside of your home?


The first step to fixing peeling paint is to work out how and why it's happening. The properties of the paint are a good indicator of its effectiveness in application-ALWAYS use the right paint for the right surface!

5 Steps To Fix Peeling Paint On Your Property

Fixing peeling paint is not a quick job – but by doing it once, and getting it right the first time, you can have many years of crack free paint on your home’s exterior. The effort really is worthwhile:

Step 1: Work Out The Cause:

On exterior walls, the main cause of peeling paint is moisture that has seeped into the wood or brick surface. The first step towards ensuring you fix peeling paint for good is to work out how and why this is happening.

There may be a leaking pipe that is causing water to make contact with the wall, or there could be small cracks in the wall surface that is allowing water penetration. You will need to fix these issues before you can tackle the paint job.

Step 2: Remove The Old Paint:

You now need to remove all of the old flaky paint. The best way is with a simple paint scraper, or a disc sander. By using a coarse sandpaper to start with, and working down to a smoother finish, you can remove all of the old paint and take the walls back to the original wood. This is the best surface for applying new paint. Don’t forget that some old paint can have lead content.

You should protect yourself from this, and capture as much of the removed paint as possible for disposal. You can also use a pressure washer to remove old paint, but make sure the walls are completely dry before starting the repainting job.


Areas where two materials meet, such as around window frames, are particularly prone to cracking and holes, and, in most cases, will require subsequent filling and sanding

Step 3: Repair Rotten Sections And Replace With New Wood:

You may now see that there are holes and rotten sections that will need replacing and fixing before you can start painting. Use a wood filler for this job, and ensure that this is sanded down once dry. Masonry may require repainting, or cracks to be filled.

Take particular note of areas where two materials meet, such as around window frames. These areas may be especially prone to cracking and holes, and could require subsequent filling and sanding.

Step 4: Apply The Primer And Consider Protective Coatings:

Newly exposed wood is not a perfect surface to paint directly onto. You should use a primer before you add your choice of house paint.

You could also consider using a protective paint or coating that will protect from moisture issues in the future.

Step 5: Suss Out The Right Paint For Your Property:

Choose a paint that meets all of your exterior wall requirements. The paint you choose should be protective, long lasting and in a colour that you like.

You may need to do two or more coats to achieve the finish you want, but by applying enough of the paint, you are preventing possible gaps where moisture can enter, and ultimately ruin all your hard work.


If peeling paint is causing you a problem, you have a choice of stripping the walls, and painting with normal house paint-or sourcing a specialist hydrophobic paint that gives moisture its marching orders. Needless to say, there really is no contest!

Hydrophobic Paints: The Future Of House Paint

If your exterior paint peeling problems are caused by moisture in your wall, the answer is to choose a paint that will protect those walls from dampness. This can be beneficial for your exterior paintwork and also for the interior of your home.

Hydrophobic paints and coatings are designed to fill and coat those tiny cracks and fissures in your wood cladding and masonry, giving your home a raincoat that will protect it in all weathers.

These paints will stop the surface from absorbing moisture, and the rain will simply bead and run off the surface. This is helpful in so many ways. If water was to enter the walls of your home, it can cause small cracks to expand, due to the freezing and thawing cycles.

This makes a small problem into a much larger one. Additionally, the inside of your home can become damp due to water seeping through the walls from outside. This can cause damp and mildew.

But it is the paint job on your home that will be most positively affected by the use of these paints and coatings. Available in a variety of colours, these paints are ideal for most homes and are easily applied. The paint will coat the surface, but still allow the walls to breathe.

This means that any moisture already in the walls will be able to escape and dry out – preventing future cracking and peeling. The surface is also easy to keep clean and will reject water.

If peeling paint is causing you a problem, you have the choice of stripping the walls, and painting with normal house paint. Or you can choose a specialist paint that is designed for these moisture laden areas. Sorted!
