Best Basement Waterproofing Paint Reviewed 2020
Here, I am going to review 6 of the very best waterproofing paints for basement available in the market. By reading these reviews, you will have a much clearer understanding of the product, and you will get to know about the options in your hand.
1. Liquid Rubber Foundation | Best Paint for Concrete Walls in Basement
Liquid Rubber has made its name in the last 2 decades by consistently making high-quality products that are also very nature friendly. In this product as well, they go the extra mile to make it as safe as possible.
To ensure the safety of their product, Liquid Rubber makes sure not to use any volatile organic compounds, which is something most paints never do. That makes this paint totally non-flammable. So the paint is completely safe for adults, kids, pets, and plants.
The paint primarily uses water-based enamel. While it doesn’t have the thickness of latex or oil-based formula, it is extremely easy to use. The thin liquid is very easy to apply and spread. It gives you coverage of 50 square feet per gallon.
This also contributes to the elongation. And this paint offers 900% elongation, and that is more than any other paint out there. If versatility is something you look for in paints, this one has you covered. You can apply it on basement walls, fence posts, metal, wood, concrete, etc.
However, the paint also has some drawbacks. For example, it can be quite difficult to clean. So the room for mistakes is very small with this one. Again, it doesn’t work well with a standard brush. You need to get a brush of higher quality to make the most out of this paint.
2. Rubberseal Liquid Rubber | Best Waterproof Basement Paint
Rubberseal credits itself for making high-quality premium grade products. While that is true to a certain extent, it also means their products can be a little expensive. This product follows that ethos perfectly. However, it does come with many impressive features that make up for its additional cost.
Firstly, the thickness of this paint is just the right amount. It is thick enough so that it can seal the pores of the walls properly. But it isn’t so thin that you cannot spread it properly. In fact, it spreads very easily. The coverage of this paint is 60 square feet per gallon.
Secondly, this paint also cares about your safety. While it does use some volatile organic compounds, it keeps the amount to an absolute minimum. Also, it is completely non-flammable.
Thirdly, the paint is very easy to clean. So even if you make mistakes, you can clean it easily. However, a big complaint against the paint is that it takes too long to dry. Under normal circumstances, it takes at least 4-5 days to dry. Again, it can get very porous after drying, and thus it opens itself up to seepages.
3. KILZ Interior/Exterior Waterproof Basement Paint
When it comes to paint companies, KILZ is a company that I always trust. They have been consistently making high-quality paints at an affordable price for about 40 years now.
Even in the conversation of the best basement wall waterproofing paint, KILZ makes a name for itself with this product.
A unique feature of this paint is that it uses nanotechnology to form a barrier that prevents water infiltration. This also makes the coating resistant to alkali. You can use the paint in basements, cinder and concrete blocks, and masonry walls. So this paint is definitely for those who want to kill multiple birds with one stone.
Unlike low-quality paints, you do not need to use way too many coatings to get the best results. A single coating will serve you well enough. However, for the best possible result, I would advise giving the wall two coatings of this paint.
The drying time is exceptionally fast with this paint. In only 1 hour, it becomes dry enough to touch. In a matter of only 4 hours, you can recoat it.
4. Drylok 28613 Extreme Latex Masonry Waterproofer
Drylok is perhaps one of the most popular paint companies. While a lot of it can be credited to their affordable prices, the quality of the products definitely plays a huge role in it. The 28613 here, for example, comes at an extremely low cost. But it delivers a quality that is almost as good as that of the expensive models.
Among all the features of this paint, its efficiency ranks very high. This paint can endure 15 PSI of hydrostatic pressure, which is instrumental in keeping your walls waterproof. It also protects the walls from harmful radon gas that can ruin the quality of your walls.
Even in terms of safety, this paint is a good option. The VOC count on this paint is extremely low, which ensures maximum safety.
And the thickness of the paint is perfectly balanced. It is quite thin compared to many other waterproofing paints. That means it has comparatively more coverage as well. But it isn’t so thin that the waterproofing ability reduces. With 2 coatings only, you can have sufficient thickness.
Like any product, this paint also has some factors that will not be appreciated by everybody. Firstly, it has a very strong odor that can be annoying for many. Secondly, it takes a long while to dry properly.
5. Ames Water Base High Strength Elastomeric Liquid Rubber
Ames is one of the more underrated paint companies. But they definitely have an eye for quality, and this product is a testament to that.
This paint is perhaps the thinnest paint on the list. That is why it provides one of the highest coverage at 100 square feet per gallon. Coverage like this makes the paint convenient for the users. The elastic properties of the paint also deserve praise. The paint can offer 700% elongation, and that makes the paint even easier to use.
Like Liquid Rubber paint in our second review, this paint uses absolutely no volatile organic compounds. This makes the paint completely non-toxic, non-flammable, and perfectly safe for the family, pets, and plants.
The company plays special attention to the convenience of the user. A strong odor can alienate many people from good paints. So they went the extra mile to neutralize any form of odor in this paint. Additionally, it takes a maximum of 24 hours to dry properly. Thus it doesn’t test your patience too much.
6. INSL-X AMW100009 A-01 Basement Wall Waterproofing Paint
While this may be a lesser-known paint, it definitely has some noteworthy features that make it stand out. While this is by no means the best basement waterproofing paint, all things considered, some of its features are definitely worth praising.
Firstly, we need to talk about the efficiency of this paint. This company takes waterproofing very seriously. And so this paint can endure about 12 pounds of hydrostatic pressure per square inch. This endurance goes a long way to avoid seepages on your basement walls.
Secondly, this is completely a water-based paint. While there are some merits to this property, there are also some demerits. In terms of the merits, the ease of use is very high up there. Because of the thinner texture, it spreads better and has more coverage (75-125 square feet per gallon).
But water-based paints are traditionally not as efficient as latex or oil-based paints in terms of longevity, protection, and thickness.
Special emphasis has been put to make this paint resistant to all sorts of molds and mildews. Not only that, but this paint is also resistant to alkali, which greatly enhances the protection of your walls.
One thing that really adds to the convenience of using this paint is the fact that you don’t even need to wet the surface to apply it. This is one of the advantages of a thin texture.

How to Choose Right Basement Waterproofing Paint?
Reading all of the product reviews, you should have a much clearer conception of what makes a product the best basement waterproofing paint. In this section of the article, I will help you further and guide you through choosing the right one.
To choose the right waterproofing paint, you need to take the following things into consideration.
Formula of Paint
Generally, there are three types of formulae used in paints. These are water-based, latex-based, and oil-based. Each type has its own utilities.
The water-based paints are usually very thin in texture. That is why they have more coverage compared to the other types of paints. That is why it is very easy to use these types of paint, and they take comparatively little time. But in terms of protection and waterproofing, these types of paints lag behind their counterparts.
Latex-based and oil-based paints can offer a much higher degree of protection. Oil-based paints deliver the highest degree of protection and waterproofing. But they are often considered difficult to use by newbies because of their thickness. That is why a lot of people prefer the latex-based paint more.
Like many forms of paints, waterproofing paints can be dangerous as well. Some paints use volatile organic compounds to increase the thickness. If the amount of VOCs is too much in your paint, it can be very risky to use, especially for plants and pets.
So while buying the right paint for your basement, definitely take this into consideration. There are many waterproofing paints that don’t use any VOCs. It is better to get those to ensure maximum safety.
This article is primarily directed at those who want to waterproof their basement walls. But we understand if you want to use your paint for multiple purposes. That is why I put emphasis on versatility in the reviews.
There are many paints that you can use on multiple surfaces like concrete, metal, wood, rooftops, etc. I made a point of mentioning them in detail. So by referring to the reviews, you will get a good idea of how versatile each of the selected paints is.
Waterproofing paints generally take more time to properly dry compared to other types of paints. But in general, most waterproof paints take about 24 hours to dry properly. That is the ideal drying time.
If the coating of the paint can dry faster than that, then you are in luck. But it shouldn’t take too much longer than 24 hours.
What Are The Benefits of Using Basement Waterproofing Paint?
Basement waterproofing paints cannot exactly cure leaks in your walls. If your walls are dealing with internal leakages, then coating it with waterproof paint will not exactly help solve the main issue. Then what does a basement waterproofing paint do? Here, we will answer that exact question.
The following are the benefits you will get from the basement waterproofing paint.
Preventing Diffusion of Water
Concrete basements are generally very porous. So it is very natural to see the diffusion of water into these pores. This diffusion causes seepages in the walls. The problem is further accentuated during harsh weather conditions.
By applying basement waterproofing paint, you can avoid this problem to a certain extent. These paints fill up the aforementioned pores and create a vapor barrier that prevents diffusion of water. Thus, it protects your wall from seepages.
Resistant to Mold and Mildew
Molds and mildews are types of fungi that usually develop as a result of excessive moisture. Without proper waterproofing measures, they can easily grow on your wall when it is exposed to moisture.
By applying the proper waterproofing paint, you can protect your walls from such moisture and, in turn, from molds and mildews as well.
Increasing the Longevity of Your Walls
After all internal leaks have been fixed, waterproofing paint can act as a sort of insurance. It will protect the wall from moisture and keep it healthy for a longer period of time. While internal leaks are a whole different story, this paint will handle any and all forms of seepages.
How to Apply Waterproofing Paint in Your Basement
Now that you know almost everything there is to know about waterproofing paints, it is time to know how you are supposed to apply them on your basement walls. The following method is the easiest and most hassle-free method of using waterproofing paints.
Step-1: Select the right waterproofing paint and store it in a bucket at a reasonable distance from yourself.
Step-2: Remove any pre-existing paint from the walls. Some waterproofing paints can be used over other paints as well. But I would advise having the pre-existing paint removed for the best results.
Step-3: Coat a paintbrush with the paint and trim around floors, ceilings, windows, and corners. This will create a barrier of paint so that you don’t paint over these areas by mistake.
Step-4: Use a spray bottle to paint the entirety of the walls with the waterproofing paints. You could try to use a roller for this. But some paints can be way too thick to be used on a roller. So I would advise using a spray bottle instead.
People Also Asked (FAQs)
Below are the most commonly asked queries regarding the ideal waterproofing paints:
How to Remove Waterproofing Paint?
There are multiple ways in which you can remove waterproofing paint. I prefer to use a pneumatic hammer as that gives the best results. However, you can find many other solutions online, as well.
How Long Does Waterproofing Paint Last?
Generally, a coating from one of the good waterproofing paints should last about 10 years. But that greatly depends on the weather conditions of your area.
How Many Coatings Do Waterproofing Paints Need?
I would advise giving your walls at least 2 coatings to get the optimal results. But some paints may require more than that. If a paint requires more than 4 coatings, that paint simply isn’t worth buying.
Which Type of Enamel is Based on Waterproofing?
You can get the highest degree of waterproofing from oil-based enamel. But they are generally more difficult to use compared to the water-based or latex-based ones.
How Long Does it Take for a Waterproofing Paint to Dry?
Generally, it takes 24 hours for the paint to dry completely. However, that time can change based on the weather conditions of that area.
With all that being said, there is only one thing left to do. And that is to go out and get the right waterproofing paint. Basement waterproofing paints can be an essential insurance policy against excessive moisture. It is a fantastic tool for protecting your walls from harm and increasing its longevity.
