Painting an Outdoor Swimming Pool In Summer

With this record beating summer we are experiencing Promain have been receiving a huge increase in enquiries for outdoor swimming pool paint. We would like to give our customers guidance against potential pitfalls before they happen. If you are new to outdoor swimming pools having graduated from inflatable pools or kids swimming pools Promain can offer advice on the correct way to prepare and paint your swimming pool.

The Correct Weather Conditions For Painting Your Outdoor Swimming Pool

Outdoor Swimming Pool

There are a couple or guidelines to painting a swimming pool we would like to share with you. The most important of these is DO NOT paint your pool in direct sunlight on a hot afternoon.

The reason behind this is we want the paint to have time to soak into either the existing paint or the render before it dries. The blend of solvents used for swimming pool paints will evaporate extremely quickly in the current temperatures and the paint will start to dry on the end of your brush or your roller.

Our recommendation is to get up very early whilst it is still cool and start you painting then. Do not try to rush the painting or you will find that the roller will leave small imperfections that often look like small volcano’s in the surface. These areas will not only leave a rough finish but the paint will not have the required thickness. The consequences of that is the water will be able to eat its way into the paint causing premature failure.

Premature Filling of Your Garden Swimming Pool

After painting, do not rush to fill your pool with water. It might be tempting as you want to enjoy your pool as soon as possible. Allow at least 10 days for the paint to properly cure before you fill it with water. Do not run your pool heater whilst filling your pool.

Chemical Introduction To Your Outdoor Swimming Pool

Always fill the pool completely with fresh water before adding your swimming pool chemicals. As it takes some considerable time to repaint and repair an outdoor swimming pool, it is important not to undo all your hard work by adding the chemicals too fast, making them too concentrated which will in turn either bleach the colour from the swimming pool floor and walls or will break the paint down causing it to fail.

We would recommend customers to slowly add your chemicals so that the chemicals are not to concentrated. It may be an idea to introduce them in the centre the pool and continually mix by scooping up swimming pool water in a bucket and throwing it back into the pool. Always have your swimming pool pumps recycling to aid mixing.

Do not leave pool floats, swimming pool toys or swimming pool games in the pool while introducing chemicals such as chlorine, PH reducer or PH increaser. These chemicals may effect the toys.
