The swimming pool like any other structure requires periodic maintenance. The best period to do these activities is during initial months of the year. This time is always beneficial because it is cool and once the work is complete, you can easily refill the pool. The pool painting is the best option to maintain the swimming pool and extend its life. However, before you start with painting, it is important that the inspection of cracks, chips in the concrete pool have to be done with great care. If there are any cracks, then repairs have to be conducted in the concrete pool with chlorinated rubber. If the cracks are a bit lager, then patching compound can be used. These things are specifically made to be used for the concrete pools. On the other hand, the pools of fiberglass do not require repair if the hairline crack open to the substrate. This is a sign of weathering. Immediately repair the cracks in fiberglass pool, as water can damage the substrate and rot it.
