Do you know what is the best sealant for hot tub spa repairs or the best glue for hot tub repair? If you own a hot tub, you will have to learn about how to fix a leak every now and then.
It’s obviously quite common in these things, since they are constantly filled with water. Instead of having to replace entire components, you could save money by making use of a leak sealer.
Most people who own a hot tub already know a thing or two about sealants that are used for closing leaks, but there are still many people who have their reservations about such products.
In the following paragraphs, we will talk about sealants in general, how they work, and whether they are actually suitable or not. More importantly, we’ll provide steps on how you can apply them on your hot tub.
What Are Sealants?
To put it concisely, a sealant is a liquid that is designed for sealing a leak in your hot tub or pool. The sealant is a cost-effective solution for people who don’t want to pay a lot of money for repairs.
Instead of having to replace an expensive pipe or internal component, simply applying the sealant is a less expensive option. It is also created in a way so as to minimize damage to the filters or the spa.
It is also not affected by the chemicals added to your hot tub, such as the bromine or chlorine. The sealant can be used underwater as well.
In most cases, you will have to mix the sealant properly in water and then apply it. It hardens over time and creates a strong seal that cannot be removed easily.
What Kind of Leakages Are Best Closed by a Sealant?
Now, you have to understand that while sealants are a good option, they are not the ultimate option. You can’t use sealants for everything on your property.
While it’s a fantastic solution for use on smaller cracks or leaks, it may not be a wise choice for larger cracks. The sealant can be used in all kinds of pools, spas, and hot tubs.
More importantly, you can also use the sealant in a range of housing, return lines, suction lines, fittings, and skimmers. In case the loss of water in your hot tub is below 3 mm a day, using a sealant to plug the leak is a good idea.
Similarly, you can use sealant in your pool if the water loss is a maximum of 50 mm a day. Anything more, and you might have to consider alternate solutions.
If the level of salt in your hot tub is above 3,000 ppm (you can check it yourself), using a sealant is a wise idea. Don’t think that you can apply the sealant on your aquarium.
This thing doesn’t work well in aquariums or virtually any place where you keep living beings. Similarly, if you have a bigger spa and the water loss is much more than 3 mm a day, using a sealant is not an effective option.
There are going to be situations where you might not be sure about whether the sealant is the right choice or not. If that’s the case, it definitely doesn’t hurt to try.
Just apply the sealant and see if that fixes the problem. If it doesn’t, well you will have to fork out the money anyway.
Best Sealant For Hot Tub Spa Repairs
If you search online, you will come across hundreds of different sealants that you can use. However, not all of them are a good choice, obviously. Instead, you will have to do your research carefully to find a decent sealant.
The best way to look for a sealant is to search online and then go through reviews. A majority of the websites from where you can buy online, such as Amazon, offer product reviews from customers.
This way, you can easily get a better idea about whether you are buying something that fits your needs or not. You can also compare prices from various vendors before you make a decision. Once you buy the sealant, you will also have to apply it on the hot tub.

Step-by-Step Instructions for Applying the Leak Sealant
If you have bought a robust leak sealer, you need to be mindful about the application procedure. There is a chance that you might not get an appropriate result while doing the work.
The first step is to identify where the water is leaking from. This should be done as quickly as possible once you identify the leakage. If the hot tub is kept out in the garden, the leaking water is going to cause immeasurable damage to your plants.
This water contains a ton of chemicals, and you really don’t want it seeping all the way into the soil. You should first fill the water in your hot tub and then mark the level. Then, give it a break for about a day or two and see if the water level has depleted.
If there’s a leakage, the water level will fall. It’s a clear sign that there’s something wrong and water is leaking from your hot tub, albeit in smaller quantities.
How Much Sealant Do You Need?
The next step is to determine the quantity of sealant that you are going to need. Most hot tubs require at least 120 ml of sealant for every 250 gallons of water.
You may want to refer to the instruction manual or the feature list of your hot tub to get a better idea about the maximum volume of water in the tub.
Once you know the figure, you can just calculate accordingly. For instance, if you have a hot tub that is designed to hold six people, the capacity is probably going to be around 350 gallons of water.
As a result, you are going to need roughly 165 ml of sealant for this. Another thing you need to understand is that there might be situations when you will have to apply the sealant again.
In some cases, if the water doesn’t hold, you may have to add even more than necessary. Once you know the desired quantity of sealant that should be applied, the next step is to get rid of all the filters that may cause an obstruction in the sealing process.
For instance, in case the sealant passes through the filter, it may get stuck and the filter will have to be replaced as well. Why take the risk? You should continue circulating the water throughout the empty filter tank.
Keep in mind that the sealant is going to work just as well, regardless of the temperature of the water. However, it’s highly recommended that you do not let the water get really cold, such as below 70°F.
On the other hand, it would be a wise idea not to add the sealant in really hot water. Make sure that the temperature does not exceed 100°F when you add it.
Once it’s added, just turn the pump on and start by shaking the suspension of the hot tub. Keep adding the sealant carefully and make sure that it is allowed to circulate.
The seal itself is going to be quite heavy, so it’s probably going to fall down at the bottom of the pump. Using a broom with soft bristles is another excellent idea.
You should continue circulating the water through the pipes until you realize that it is no longer leaking. This could take upwards of eight hours, so it’s important for you to be patient when carrying out the process.
Once you are done, close the system. Now, it’s time to check whether the system is leaking again or not. You need to start by making the measurements just as you did before; fill up the hot tub and then mark the maximum point of the water level.
Then, leave it for a few days and then check whether the hot tub is leaking water again or not. If the water level remains the same, you don’t have much to worry about.
Keep in mind that some of the water may reduce due to evaporation, but the difference is so marginal that it’s virtually impossible to notice.
So, if you notice the water level dropping and think that this is because of evaporation, you might want to check again. That is really not the problem.
If the leak does not stop even after you try it several times, it is probably because the leak exists in a much more difficult spot and is too large to close on its own or with the help of a sealant.
In this situation, your only option will be to get in touch with a professional repairman. They are going to check the sealant on your hot tub and then determine whether the leak can be plugged or if the only option is to replace the leaking components.
