Fiberglass pools, like fiberglass boats, are finished with a tough, smooth coating known as gelcoat. Although long-lasting, gelcoat does degrade over time from UV and chemical exposure. Common signs of a gelcoat gone bad are chalking, cracking, discoloration, and blistering.
Over time, the plaster coating or surface can begin to degrade. This must be repaired. The frequency of treatment depends on the location. First, you will need to repair any cracks or spalling. Next, you must prepare the entire pool shell. Preparation is the process of removing loose plaster and roughening the surface in order to bond any new plaster layers. All methods used in prep include chipping, sandblasting, and chemical top etching.
A pool heater can save you months of swimming time. Pool heaters keep your water at a pleasant temperature, even in colder weather.
