“Aggregate” is often a misnomer in pool building – it is still considered pool plaster. The proper term is exposed aggregate pool plaster. White, very fine, smooth marble plaster was the norm until the 1980s. Exposed aggregate pool finishes feature colorful sands and pebbles and were introduced to the pool industry in the 1980s. Both types of pool plaster are used today.
Paint can also get dusty and may not bond well to plaster. You can do the job yourself if your pool has been painted. I recommend that you have your pool replastered by a professional company if the plaster is not in good condition. If you change your pool's plaster to paint, you won't be satisfied for the long-term.
Gelcoat pool application is a factory process so it can't be easily replicated in your yard. Instead, there are replacement coatings--thermoplastic polymers that are used to resurface fiberglass. Before the new coating can apply, the pool must first be completely drain and sanded.
