How Long Does Kool Deck Last (Kool Decking Lifespan)

If you are looking into purchasing a Kool deck, then you will have quickly realized that it is not the cheapest material to purchase. However, it is certainly worth purchasing when you take into consideration how strong it is. It not only helps to preserve base concrete, but it also looks more aesthetically pleasing too. 

When it comes to Kool deck, it is typically held to a quite high esteem, given that it is known to be durable and tough. However, you may have wondered how long it actually lasts for, before it needs to be touched up or replaced.

In this article, we will be talking you through the lifespan of Kool decking, how much it typically costs to replace it, and the best way to clean this concrete. 

What Is Kool Deck?

Kool deck is a branded type of concrete that was created by Mortex, in 1962. It is a coating that is most commonly placed over concrete. This is done to prolong the life of the base concrete, and also because it looks more aesthetically pleasing. It is well-made, and is typically as strong as the concrete it covers, which is great as you will want it to be long-lasting.

It can be used for many different purposes, but most commonly, it is used to surround concrete pools, sidewalks, walkways, and patios. Furthermore, it is applied after the base concrete has been placed and set.

Given that Kool Deck is created using concrete, it has high expectations attached to it. Concrete typically lasts for a long time, and is slow to wear due to the weather or damage. What is great about Kool deck is that it does live up to the hype that surrounds it.

It is well-made, durable, and long-lasting. It is able to withstand freeze-thaw with no issues, and it does well in all weather conditions. When you take into consideration that it is a material used at pool sides, it needs to be durable when it comes to water damage, which it is.

While cement is not typically linked to being a flexible material, the hydrostatic pressure within the Kool deck expands and contracts in changing weather conditions without damaging. This also allows the base cement to breathe and not be affected by this. Essentially, the Kool deck acts as a barrier. 

The length of time the Kool deck will last for can vary depending on a number of factors. However, it does not need to be managed or replaced often. On average, the Kool deck should last for a minimum of 10 years, and this is without any real maintenance.

If you were to take good care of the Kool deck and carry out the correct upkeep and maintenance, it can last for many years with no issues. Ultimately, the Kool deck once installed should not need to be replaced for a very long time. Even if you have a salt water swimming pool, this will not cause damage to the surface.

How much does it cost to replace a Kool deck?

If you are in the position where you need to replace a Kool deck, it is useful to have a rough price guide to work on. It is worth noting that the price of a Kool deck will vary slightly depending on where it is purchased. In addition to this, different states can potentially charge different prices too. You will also need to take into consideration the installation on top of the material costs.

In addition to this, you will want to ensure that you purchase the official Kool deck. There are some manufacturers that created a finishing concrete similar to Kool deck, but it is not branded. As a result, there are no guarantees in comparison to purchase the official Kool deck.

On average, a Kool deck will cost around $4 per square foot, and the price will vary depending on how big the surface area is. The larger the area, the more expensive the Kool deck will be. In some instances, you may find that the Kool deck only costs $4 per square foot. It is worth noting that the cost can be as high as $8 — $9 in some instances.

How do you maintain a kool deck?

As we have already touched upon, the Kool deck is a very durable material. Given this, it does not require a lot of upkeep, you will just need to carry out general maintenance such as cleaning every so often. 

The cleaning and maintaining process is fairly easy. All you will need is an outdoor bristle broom and soap. You will want to place the soap or laundry detergent on to the surface, and then you can scrub it in with the brush like this one (on Amazon). After you have done this, you will want to wash the soap away with clean water. 

If there are some more difficult stains, you can opt to use bleach. However, this is something you will want to avoid using too much of, as bleach is a very harsh cleaning product.

In addition to this, you can potentially use a pressure washer like this (on Amazon) sparingly too. Although, you will want to choose a setting that is not too powerful to ensure that you are not damaging the concrete. 

It is recommended that you have the Kool deck buffed annually. This can be done by a professional, and it will help to keep it maintained and in a good condition. It will remove the build up of minerals that have accumulated over time. 


We hope that you have found this article useful and informative. As you can see, Kool deck is a strong material, and it is something that will last you for a minimum of 10 years. However, the likelihood is that it will last for far longer than this.

All you will need to do is ensure you are keeping up with the regular maintenance and cleaning.
