The cost vs. benefit of removing all the existing plaster is more usually the overriding factor. Normally, the plaster would only be removed around fixtures and fittings and, if the waterline tile is not being replaced, a band about 3-4 inches below the tile is removed. This allows the new plaster to transition to these areas without being troweled too thin. The existing plaster should be examined for hollow spots and any delaminated areas removed as well. In preparing the rest of the existing finish for recoating there are several alternatives. In each, the goal is to provide a rough surface for the new plaster to adhere to. Acid etching the plaster with muriatic acid will roughen the finish and using an acrylic boning agent in the new plaster is a common practice. Acid etching however presents the problem of disposing of the used acid. Sand blasting is another means, though it can be as expensive as the replastering itself. A growing trend is to pressure wash the existing plaster and apply a scratchcoat or precoat. Scratchcoat is a modified masonary product that bonds tenaciously with the existing finish and provides a rough finish for the new plaster.

You don't replaster a pool then paint it. For Pete's sake why do you want to paint a pool. Replastering is something left to the pros. Any one mistake could mean delamination of the new plaster. Painting a pool is a last ditch effort to fix or cover up a pool that is in bad shape before you put your house on the market to sell it. k
When you say that the water is in balance, are you just talking about Chorine, alkalinity and ph? Water hardness in balance is very important to keep the plaster smooth. Call your pool plasterer/builder -- you have a problem and it is covered under warranty. k
The primary difference between plaster and fiberglass pools lies in their surface materials. Fiberglass pools have a smooth, non-porous surface that resists algae growth and remains comfortable to the touch, while plaster surfaces can become rough over time and require more maintenance. Additionally, fiberglass pools are less prone to chipping and cracking compared to plaster pools, making them a more durable choice. If you're interested in exploring high-quality fiberglass pool options, be sure to visit Pools-Now.

Yes, plaster can stick to door frames, but the effectiveness depends on the surface preparation and the type of plaster used. It's essential to ensure that the door frame is clean, free of dust, and ideally slightly roughened to promote adhesion. If the frame is made of a non-porous material, such as metal or smooth wood, using a bonding agent may improve adherence. Additionally, applying plaster carefully and in thin layers can help achieve a better bond.
