How to Smooth Pool Plaster

Pool plaster doesn't need a professional repair.

A swimming pool with a plaster liner is generally more durable than one with a vinyl liner, for example. This is because unlike vinyl, plaster will not rip or tear to create a leak in your swimming pole. However, sometimes the plaster liner of your swimming pool might need to be repaired. If you must repair a dent in your plaster, one of the most important parts of the process is to get the plaster smooth. Otherwise, it could harden into a point that can potentially hurt someone.

Things You'll Need

• Chisel
• Hammer
• Plaster mix
• Acrylic bonding agent
• Water
• Pool trowel
• Spray bottle

Instructions

1. Drain the water in your pool until you can access the area that needs new plaster.

2. Place a chisel over the area of plaster that needs repair. Hit the back of the chisel with a hammer to remove loose pieces. Otherwise, you won't be able to get the plaster smooth.

3. Continue chiseling to create a small hole in the plaster. Angle the hole outward so that the new plaster can be smoothed inside and stick better.

4. Add together plaster mix, acrylic bonding and water. Mix with your pool trowel until it's as creamy as peanut butter.

5. Fill a spray bottle with water, and spray the side of your pool that you chiseled out. The new plaster will smooth better over a damp surface.

6. Use the pool trowel to apply the plaster mix to the area. Push the plaster into the chiseled-out area to remove air.

7. Place one end of the trowel against the hard plaster and scrape it across the new plaster to smooth it.

8. Let the plaster set for 15 minutes. Repeat the smoothing process. Push harder at the edges so that the new plaster is smoothed perfectly against the old.

9. Continue spraying the new plaster with your spray while you fill up your pool. The plaster cures better and stays smooth if it remains moist.
