The remodeling begins by draining the pool. Depending on the size of your pool, this could take 6-12 hours. Once cleared of water, the chipping out process can begin. This is where the pool’s surface is chipped and primed. If you opt for tiling, it is also done after the chipping is completed. The surface application is performed next. This is the part of the process where a pebble and plaster mixture is pumped into the pool and then hand troweled. Once the surface is completed and dried, the pool can be refilled, followed by chemical treatment.
