Are you noticing little cracks in the paint on your walls? Can you see bits of paint peeling away? Are there areas of paint that are starting to bubble up?

This can be frustrating as it doesn’t look very nice and it also makes your home look untidy and worn. It’s even more irritating if it wasn’t that long ago you last gave your walls a fresh lick of paint, so didn’t expect to be thinking about doing it again this soon!

There’s a few reasons why your paint could be peeling.

It could be down to lack of preparation carried out on the walls before the paint was applied. If it’s not cleaned properly or treated with a primer, it can’t make a binding layer for the paint to stick to, which is what stops it from slipping off the surface of the wall.

It could be that the wrong type of paint may have been used in the first place, or if different paint is put on top of existing paint – like latex on top of oil based paint for example, then again, it won’t stick to it and will start to peel.

A big problem that a lot of people come across but don’t necessarily consider is moisture. In fact, the most common problem with peeling paint is actually damp issues in the home. As a precaution, it’s worth checking that you’re plumbing and piping is ok and that you don’t have any nasty leaks that could be causing moisture to build up on your walls. Don’t be alarmed though – It’s likely that a leaky pipe isn’t causing the problem – you’d know about it if it was, as it would be much more visible and the damage would be far more severe!
Therefore, a high amount of humidity in your home in all likelihood is the cause.
If you live in a hot country like Spain, you will experience more humidity day to day. This will have a direct impact on your home. The higher the humidity levels, the more water vapour is in the air, which will penetrate your walls as the dampness will seep under the paint, which is what causes it to come away from the wall’s surface.

The most effective way to stop this problem before it can start is to invest in a proper ventilation system to stop excessive moisture building up and to keep fresh air flowing through your home. These can be easily installed, with very simple upkeep and are very cheap to run.

You may have done all the right things, like making sure the right paint was used and that the walls were prepared properly but unfortunately, if you do have a damp issue in your home, you’ll start to see it creeping back again after a while, so it’s best that you deal with the root cause.

In this case, the best advice from professionals is to invest in a ventilation system and tackle the problem at the source, otherwise those paint jobs will be happening much more often than you’d like and will become a costly pain and inconvenience to you and your families home life that you won’t want to keep repeating.
