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.

Masonry nails have very small heads, and are notoriously difficult to remove from plaster, concrete, and wooden walls. The best way to remove them, without removing the plaster, is to cut the head off so that it is flat to the wall. Then, fill in the hole and repaint, if necessary.

Break out the old plaster and plaster over the area to seal the plaster surface. It is best to lower water level in the pool first but there are patch materials that work under water.

Asbestos used to be used in the plaster mix to help strengthen the plaster. So if you are ever renovating an old pool with plaster it is best to have it tested for Asbestos.

If you're saying its your dick, then you would have to dip it in plaster (with a hole at the end so you can pee) and make sure your penis is straight so it wont have a bend when you take of the plaster cast. The best plaster to use for this is plaster of Paris because its cheap, reliable, and easy to get.
