Pool plastering is an essential aspect of pool maintenance that ensures your pool’s longevity and aesthetic appeal. Whether you are constructing a new pool or in need of pool replastering renovations for an old one, pool plastering is a process that requires careful planning and execution.
In this guide, we concentrate on pool replastering renovations and discuss the following:
- Can you plaster over the existing pool plaster?
- What are the steps in replastering a swimming pool?
- How often should a plaster pool be resurfaced?
- How many hours does it take to plaster a pool?
Replastering Over Existing Pool Plaster
Yes, it is possible to plaster over existing pool plaster. However, before doing so, it’s crucial to thoroughly evaluate the condition of the existing application to determine whether it’s a viable surface for a new layer of plaster.
It is not recommended to replaster if the existing pool has more than one layer of plaster. In this case, the outer layers must be removed entirely. The new application should only be applied to the original plaster layer.
Each layer of plaster will be between 1/2″ to 3/4″; therefore, this original plaster layer must be in good condition with minor surface imperfections easily fixed, ensuring it’s a suitable substrate for a new layer of plaster.
If the existing plaster is in poor condition, with significant cracking or delamination, it may not be suitable for a new layer of plaster. In such cases, the original application must be removed and start fresh with a new plaster surface applied to the concrete shell.
Having more than two layers is not always recommended, as the third application may have significant visual detraction.
Pool Replastering Renovations Steps
Step 1 – Preparation
Before beginning the pool plastering process, the pool needs to be ready. Start by draining the pool and removing any debris or dirt that may have accumulated on the surface. The pool must also be thoroughly cleaned and inspected for cracks, leaks, and other damage that may need to be repaired before plastering.
Step 2 – Surface Preparation
The next step is to prepare the pool surface for plastering. This involves applying a bond coat, a mixture of cement and water, that creates a rough surface for the plaster to adhere to. The bond coat is applied to the entire pool surface using a trowel or sprayer, and it is left to dry for at least 24 hours.
Step 3 – Mixing and Applying Plaster
Once the bond coat has dried, it’s time to mix and apply the plaster. The plaster mixture typically comprises white Portland cement, marble dust, and water. The mixture is prepared in a mixer until it has a smooth consistency.
The plaster is applied to the pool surface using a trowel, working in small sections to ensure the application is evenly spread. The thickness of the plaster should be between 1/2 and 3/4 inches and applied in two layers. Each layer must dry for at least 24 hours before applying the next layer.
Step 4 – Finishing
Once the final layer of plaster has been applied, it’s time to finish the pool surface. This involves smoothing rough spots or uneven areas using a trowel or sander. Please note a slope around the edges must be created to ensure proper drainage.
Step 5 – Filling and Curing
After finishing the pool surface, it’s time to fill it with water. Fill it slowly to avoid damaging the new plaster. In addition, the water must be tested to ensure the pH and chlorine levels are correct.
Once the pool is filled, and the chemical levels are accurate, it can take seven to ten days to cure fully; however, if the pool is clean and chemical levels are correct, you can go for the swim you have long waited for.
How Often Should Pool Be Replastered?
On average, an inground swimming pool should be replastered every seven to ten years. When pools are adequately maintained with proper chemical levels, a replaster need may be ten to fifteen years. Age is not always a determining factor, as it may be time to replaster when the plaster becomes rough.
Replaster Renovations Time-Frame
Generally, pool replastering renovations take five to seven days. However, the process can be hindered by weather, therefore, can take two weeks or even more.
