There are many reasons why your pool paint might be peeling. The most common reasons are poor surface preparation, excessive moisture, poor workmanship, and water leakages. Together, these problems can not only reduce the visual appeal of your pool, but also cost you a fortune in repairs.
In order to figure out why your pool paint is peeling, you need to pinpoint the source of the problem. Here’s a quick breakdown of the most common symptoms of a pool with surface issues.
Improper surface preparation-
When a pool painter comes to paint (or repaint) your pool, they need to prepare the surface first. More specifically, the existing surface that is already there, to which the new layer of paint will be applied over.
To prepare the surface of a pool, pool painters perform a number of tasks. Most of these tasks involve removing any imperfections that exist on the surface. Some examples of these imperfections include the presence of dust and dirt, oil, blisters, bubbles, craters, cracking, and brush marks.
If the pool painter were to apply a new topcoat over the existing layer without preparing the surface first, the results would be poor. As you can probably guess, paint peeling is just one of the many symptoms of poor surface preparation.
However, by performing tasks like sandblasting the surface, power washing, and general cleaning, pool painters can comfortably apply a new layer of paint over the surface. This then gives them (and you, the pool owner) the confidence that the finish will be the best it can possibly be. More importantly, it’ll save you money in the long-term, as the new layer will last for longer and therefore won’t need to be reapplied sooner.
Certain types of pool paint can only be applied in dry, moisture-less conditions. This is a common requirement for epoxy and rubber pool paint, as they are not compatible with water.
So, in order to apply these types of pool paint, a technician must completely drain the pool first. They then need to let the pool sit for a number of days – with consecutive dry weather – until the surface is ready. This is easier said than done, as even a single day of bad weather can restart the drying cycle, resulting in longer waiting times.
What does this have to do with moisture? Well, unfortunately, if a pool painter does not follow the proper guidelines for pool paint waiting times, problems occur.
When they apply the new epoxy or cement-based layer, the interior moisture still present in the pool can lead to exterior paint blistering, which kind of look like bubbles. And since there’s no way for the trapped moisture to escape, when direct sunlight hits the surface, it causes the water trapped behind the paint to evaporate. As a result, bubbles and blistering can appear.

Wrong type of pool paint-
It’s important to repaint your pool with the same type of paint that was used before. So, if your pool was painted with Epoxy, use Epoxy. If it was painted with a rubber-based paint, then go over it again with rubber.
Be careful, as choosing the wrong type of pool paint can lead to disastrous results. And paint peeling being one of the biggest problems. This is because the new type of pool paint won’t bond well with the other one. As a result, the new layer won’t last for long, and it’ll eventually start peeling off.
There are lots of minor mistakes that a pool painter can make while on the job, which can negatively impact the quality of the final finish.
Firstly, they might be using a low quality roller to apply the new paint. This can lead to an uneven distribution of paint, resulting in a poor looking finish. Secondly, they might apply too many coats at once, causing the multiple layers of paint to ‘un-adhere’ from one another. Or thirdly, they might have shaken or stirred the paint too much before applying. When this happens, tiny pockets of air remain trapped in the paint, which then transfer onto the surface once applied, resulting in bubbles and the potential for peeling.
Make sure you hire a fully licensed and qualified pool painter, one with experience working on pools just like yours. They should also know which type of paint is right for you, how to apply it correctly, and how to maintain it for your long-term enjoyment. Most importantly, they should be completely transparent about their process, explaining to you what work needs to be done and why. This way, you can be confident that your pool painters know what they’re doing.
