Once the primer is dry you can paint the pool with topcoat epoxy or resurfacing solutions. Following the manufacturer's guidelines and recommendations, paint from the deepest to the shallowest. Allow the topcoat to dry completely before you apply the next coat. Sand the pool between coats to ensure proper adhesion. Most pools will require between three and four coats. It can take several hours depending on the climate.
Plaster must be in good order before you can repaint an existing pool. Pros recommend that you prepare the plaster surface with a wash using muriatic acids, then rinse it with TSP (trisodiumphosphate), and finally water. Note: Always use TSP (trisodium phosphate) and muriatic acids with extreme caution. It is important that the old paint be compatible with the new one. Rubberized latex paint, for example, won't stick to epoxy.
There are two types of pebbles: polished and exposed. Exposure is when all the pebbles are visible, leaving a rough texture or finish. Polished, on the other hand, produces a smooth texture and the surface is flat.
