Pool replastering is a repair solution. If your pool is showing signs of age, like stains, small cracks and chips, roughness and color loss, you can replaster the interior to achieve a like-new look. Over the course of several days or weeks, your pool contractor will remove the old plaster. Then they can pour in new plaster, which needs to cure and harden. After the plaster is set, it can be sanded to smooth out any imperfections. When the plaster is finally in good shape, then the pool can be refilled—and you can get back to swimming!
