How Long does it Take to Replaster a Pool

If you own an in-ground concrete pool, replastering going to be one of the most important projects you’ll have to take on. If you’re already planning to have your pool replastered, you might be asking yourself, “how long does it take to replaster a pool?” A quick search using your internet browser will reveal a slew of results that can cause more confusion than enlightenment. So, don’t worry. We, at Valley Pool Plaster, are here to help you find out how long it will take to replaster your swimming pool. 

To help us better understand the time it would take to finish a pool plaster project, let’s look at what pool replastering is.

What is pool replastering? 

Pool replastering is the process of adding a new layer of plaster over your pool’s interior surface. Here are a few reasons why pools are replastered. 

Exposed concrete. 

Roughened surfaces. 

Cracking, etching, and spalling. 


Hard to remove stains. 

As you can see, many pool owners replaster their pools out of concerns for structural integrity, usually around every 7 to 10 years. However, some pool owners do it more often to preserve the aesthetic quality of their pools. It’s an important maintenance solution to help keep your pool last as good as it looks. 

Process of Pool Replastering 

Now that you know why pool owners have their pools replastered, let’s talk about how it’s done. Let’s start with draining the pool. 

1. Draining the pool. 

The first step of pool replastering is taking the water out of the pool. While it sounds easy, there’s more to draining the pool than meets the eye. Here’s why. 

Done the wrong way, the water drained out of the pool can penetrate into the ground creating hydrostatic pressure that can push the in-ground concrete pool upwards. That said, it’s best to have a trained and experienced professional drain your pool and carry out the necessary tasks involved in replastering your pool. 

An average-sized pool can take anywhere around 8 to 14 hours. 

2. Chipping out the plaster. 

Once the water is drained out of the pool, the next step is to chip out the old plaster. As of writing, there are two common methods practiced in removing the old interior; the chip out method and the hydroblast method. The former is carried out by manually chipping the old plaster by hand with the help of both hand and power tools like hammers, chisels, and a jackhammer. The latter, is usually achieved by using pneumatic tools, pretty much like those used for sandblasting. This is usually followed by a quick acid wash, which helps remove any loose concrete and helps improve the bond between the concrete and the new plaster. This usually takes anywhere around 4 to 6 hours. 

Here at Valley Pool Plaster, we use only the chip out method. Not only is it the National Pool Plasterers recommended means of removing the old plaster, but it also allows us to remove most of the old surface. This helps us ensure better bondage and adhesion when the new pool plaster is applied. 

Which brings us to… 

3. Applying the new plaster. 

Once the old surface is removed and the surface cleaned, it’s time to apply the new plaster. Your pool contractor will typically be using a plaster mix and can be brought to your property premixed or can be mixed on site. Nevertheless, the mixture will usually be made out of white Portland cement with a mix of a few aggregates. Some pool owners also ask their contractors to add pigmenting agents to add color to an otherwise all-white plaster. 

Pool plaster is often applied on the pool’s surface starting from the walls down to the floor. It can be applied by hand or by using pneumatic equipment spraying the plaster mix around the pool’s interior. Once the plaster is applied, it is finished by pressing the plaster close to the concrete to achieve a better bond and a smoother surface. On an average swimming pool, the application of the plaster as well as the smoothening and compacting of the surface usually takes anywhere around 4 to 8 hours. 

4. Starting-up the pool. 

After the plaster is applied and has been left to set and cure, your contractor can now start-up your pool. This is usually filling the pool with water and adjusting the pool’s chemistry. This will help in increasing the pool’s surface’s durability as the right water chemistry can help you avoid issues that can damage your pool plaster. 

Starting-up the pool usually takes anywhere around 8 to 14 hours. 

So, how long does it take to replaster a pool? 

It usually depends on the size of your swimming pool and the amount of work involved in the actual undertaking. Your pool contractor will usually have to visit the site and inspect the pool to be replastered. From here they will be able to tell how long your pool replastering project can potentially take. 

The average pool replastering project takes about 2 weeks to complete – startup included. That’s not 2 weeks of worth of work, but different jobs spread in two weeks. This includes everything from planning, ordering of the materials necessary for the project, letting things set, cure, and dry.
