Swimming Pools are a harsh environment for composites materials. They have some advantages compared to other materials, but are still affected by the sun, chemicals and temperature. Composites materials become damaged over time, and repair may be required.
Composites materials can also be used as a coating repair on top of other materials such as concrete. The epoxy seals cracks and smooths the surface for a cleaner look.
It is very important to use the correct tools and materials and follow the proper order of operations. Once all of this work is complete, you will have a very nice swimming pool!
