Steps to Replaster a Pool

Owning a pool is a big investment not only for your money but your time and energy to properly maintain its beauty for many years to come. Over time, even with excellent care, you will notice the bottom of the pool will become rough, bumpy, and also sharp in certain areas. It will become time to replace the pool plaster finish not only for the appearance but to keep it safe to use for yourself and your pool guests. 

What and When to Plaster

Plastering a pool means adding a new layer of plaster on the walls and bottom of the pool. Pools are created from either concrete or gunite to form the outside “shell.” The reason for replastering is to make the pool waterproof since it was first originally installed. The two biggest problems of these materials are that they are porous and will not hold water. As a result, the pool will need to be continuously filled as it will slowly leak water over time. A solution to this is for an installer to add a half-inch thick layer of plaster. It will not only form a better barrier, but it will also give the water a beautiful blue hue appearance and a smooth surface. No plaster is designed to last forever, but depending on the correct maintenance and use, the pool plaster will remain intact anywhere between seven and twenty years. 

Risks That Increase with Neglect

So, what happens if the pool is not cleaned or taken care of regularly? If a pool is not properly maintained during its life, there are many factors that the plaster will affect that can be very costly down the road. First, you may notice new stains appearing on the surface due to certain minerals that may be contained in the pool water, such as iron or copper, that can often give a greenish-brown tint. Although this issue is only aesthetic, it can be quite frustrating to deal with after spending so much time and money to keep it looking clean and fresh. The next issue that may occur is the surface will form lumps, bumps, and scratching spots, which will cause concern for swimmers not to get scraped when jumping and swimming around. The bumps may not be too uncomfortable, but in the long term, they will make the pool harder to clean and be a place that algae will find and grow on. Lastly, the most significant danger is it can affect the integrity of the pool structure. As discussed earlier, the plaster is a protective layer that keeps the pool waterproof; if the plaster wears away, water will seep into the concrete or gunite, causing even larger problems.

Alternatives for Replastering a Pool

If replastering your pool is not something you have the time or budget for, there are several temporary options available, but these could end up costing you more money in the long run. One option is to do a patching job. If areas of the plaster are beginning to feel rough, a plaster patch could help the issue, but aesthetically it would not match the original plaster installed. Another solution for removing pool stains is to perform an acid wash. It’s a quick fix for the stain, but it does not help in any way with preserving the plaster. In fact, the acid wash will damage the plaster further, so its best to only use this method if the aesthetics are a necessity for you. If money is no object, installing tile can be a great decision since the material is incredibly strong and beautiful to look at. However, a full pool tile job is not cheap and will set you back anywhere between $75-$100 per square foot.
