The right plaster is key to maintaining a beautiful and durable swimming pool. High-quality plaster can make all the difference, affecting both your pool’s appearance and its long-term performance. To get the best results, you need to know what to look for when sourcing your swimming pool supplies.

How to check the texture:

Good plaster should feel smooth to the touch without any sharp bits sticking out. If you run your hand across the surface and it feels like sandpaper, something went wrong during the mix. A top notch finish has a consistent feel from the shallow end all the way to the deep part. Rough spots can scrape skin and make swimming less fun for everyone.

Looking for color balance:

The shade of the plaster must look even across the entire floor and walls. You should see a solid block of color without weird dark streaks or light patches that look like clouds. If the color looks blotchy, it usually means the water was added too soon or the chemicals were off. Even tones show that the crew took their time to mix and apply everything correctly.

Checking for tiny cracks:

Small lines that look like a spider web are a bad sign for any new surface. These tiny cracks can happen if the plaster dries out too fast in the sun before the water goes in. A strong finish stays solid and does not show these marks even after a few weeks. High quality work stays firm and looks clear under the sun without any visible breaks.

Testing the thickness:

Proper plaster needs to be thick enough to protect the shell of the structure. If the layer is too thin, you might see the grey concrete underneath peaking through the white or blue finish. A thick and sturdy layer acts as a shield that keeps the water where it belongs. This thickness ensures the surface can handle the weight of the water and the chemicals used every day.

Spotting loose patches:

Sometimes plaster can pull away from the wall which creates a hollow sound. You can test this by gently tapping on the surface to see if it sounds like a drum. A solid bond means the plaster is stuck tight and will not flake off in big chunks. If the surface stays flat and attached, you know the prep work was done with great care.
