Pool & Spa Plaster Repair in Chandler


Thousands of pool owners believe they can plaster their own pool without realizing it is a lengthy and difficult process. The average gunite swimming pool will need to be plastered every seven to 10 years, depending on how it was installed and how well it has been maintained.

Most pool owners elect to have their pool plastered for cosmetic reasons because the walls of the pool have become discolored. If the walls are green or even brown rather than the gorgeous blue you desire, plastering your pool can restore it to its former glory and make your pool the envy of your neighborhood.

The Process

All working equipment must be switched off, and the pool must be drained. If there is any water remaining at the bottom, use a sump pump to clear it. There will be debris, such as dirt and leaves, left after draining, so ensure this is all cleaned before proceeding with the pool plastering process.

Look for areas where the plaster is noticeably peeling, and give special attention to corners and edges. Use a putty knife or chisel to get rid of loose plaster, and sand the sharp edges where the plaster has been removed. It may be necessary to sand the same areas twice to ensure they are clean and neat.

Spray an acid wash on the surface, and spread it out using a special acid brush. Rinse with a hose, and allow it to dry. Apply a bond coat, and let it dry for up to 24 hours. The following day, apply the plaster using a trowel according to the manufacturer’s instructions. Begin at the deepest end of the pool, and look to fill in cracks and holes. Never apply wet plaster to set plaster, and use your trowel to ensure the surface is even. Once the plaster is dry, you can get to work painting the pool before refilling it once the paint is dry.

Potential Issues

You may think the job you have completed is a professional one until a few months later when white spotting appears. This is caused by applying excess water to the surface while troweling or adding calcium chloride into the plaster mix. The result is weak and softened plaster in localized areas, along with cracking and porosity. This problem cannot be fixed and will require the surface to be replastered.
