Common additives include quartz and pebbles. Quartz is stronger than plaster and will resist staining. When quartz and pebbles are combined, they create a durable, beautiful surface that will add sparkle to your pool. QuartzScapes by NPT, and DiamondBrite from SGM are two popular quartz-plaster mixtures.
The plaster's coating or surface will wear over time and need to be resurfaced. Your pool might need to be resurfaced every ten to 20 years, depending on where it is located. First, cracks and spalling must first be repaired. Then, the whole pool shell must then be prepared. Preparation is a process that removes plaster from the surface and prepares it for new plaster layers. Preparation can be done using sandblasting, chipping and chemical surface etching.
What exactly is pool surface resurfacing, and how is it done? The new surface can't be applied to an existing pool that has been coated with fiberglass, plaster, pebble or all tile. It is necessary to prepare the surface for a new coating of plaster or pebble. This can be done by either cutting out the plaster, bonding coating the surface with sand blasting, hydroblasting or chipping the existing plaster. The National Plasterers Council states that all of these methods are acceptable, however, each method has its advantages and disadvantages. Now you can apply the plaster, quartz, exposed pebbles, glass beads or polished pool coat to the surface after it has been prepared.
