6 Popular DRYLOK Alternatives (Explained)

Drylok stands out as one of the best waterproofing products on the market. It can be used as a waterproof sealer on interiors and exteriors.

It has a transferable warranty and it does a commendable job of preventing water from seeping through your floor and walls. Drylok is available in a wide range of formulas which are ideal for various situations.

From the description, Drylok is undeniably an excellent waterproofer. However, there are certain scenarios whereby Drylok may not be available at nearby stores.

Or, you may have had some bad experiences with Drylok and would like to explore other alternatives. In today’s post, we will be exploring some of the popular Drylok alternatives that you can use to waterproof your floors and walls.


1. Quikrete Waterproofing Sealer

If the reason you are looking for a Drylok alternative is that you can’t find it in nearby stores, you should highly consider the Quikrete waterproofing sealer.

Quikrete is a pretty big name in the construction industry and their products are well distributed in all parts of the country, including in Home Depot outlets.

Like Drylok, Quikrete waterproofing sealer helps prevent moisture from passing through walls, brick, concrete floors, and stucco.

The thing that stands out about Quikrete is that it has a natural look finish. After application, it doesn’t change the surface appearance at all. It is available in 1 or 5-gallon bottles.

You can choose the desired amount depending on the surface area you wish to waterproof. Please note that a gallon of Quikrete waterproofing sealer can cover around 150 square feet.

It’s also worth mentioning that Quikrete waterproofing sealer is highly water resistant. As long as it’s applied correctly, it can last for years. This waterproofer is also known to resist mold growth and it doesn’t have a strong odor.

2. Sani-Tred Permaflex Waterproofing

For those of you who have had a bad experience with Drylok and you would like to try something different, you should consider Sani-Tred as an alternative.

Unlike Drylok which is cement-based, Sani-Tred is a liquid polyurethane coating that penetrates deeper into floors and walls creating an impermeable membrane.

Sani-Tred, apart from concrete, can be used to waterproof wood, steel, aluminum, and plastic. It’s therefore a more versatile waterproofer than its counterpart Drylok. What I love about Sani-Tred is that it doesn’t peel, crack, chip or delaminate as long as it’s applied correctly.

It may not be as popular as Quikrete and Drylok, but the Sani-Tred waterproofing coating has some pretty unique features. For instance, it has a tensile strength of 2,030 psi, compared to Drylok whose tensile strength is only 12 psi.

According to the manufacturers of Sani-Tred, it penetrates deeper into floors and walls and dries into a coating that’s as tough as a truck tire. That means no water or moisture will pass through the floor or walls and damage your foundation.

If you are tired of Drylok’s formula and you would like something much stronger, Sani-Tred is an ideal alternative.

3. Zinsser Watertite

Another popular Drylok alternative that offers better waterproofing is Zinsser Watertite. Zinsser’s formula is a bit similar to that of Drylok. They are both acrylic and oil-based waterproofers.

They can also be used on the same surfaces such as concrete walls and subfloors. Both leave behind a bright white finish. However, when it comes to waterproofing, you get more results from Zinsser Watertite than its counterpart, Drylok.

Zinsser also offers longer waterproofing capabilities. It can last for up to 20 years, unlike Drylok which can only last 15 years.

On a head-to-head comparison, Zinsser Watertite has more features and benefits than Drylok. But you need to know that Zinsser Watertite is more expensive than Drylok and the application is a bit more complex. With Drylok, you can even apply it using a sprayer.

Unfortunately, the same can’t be said for Zinsser Watertite. But when you compare the benefits that come with this Drylok alternative, the complex application process will be worth your time and effort.

4. Rub-R-Wall Waterproofing

When you look at Drylok alternatives, you will realize that there are so many waterproofing products out there that do a much better job. Rub-R-Wall is just like Sani-Tred, it’s not very popular but it does a marvelous job.

This is a liquid waterproofing product that dries into a rubber membrane. Unlike Drylok, Rub-R-Wall waterproofing is flexible, and therefore, it can withstand the movement of the subfloor. Rub-R-Wall is available in a standard and Plus version which is much stronger.

With both options, you get a limited lifetime warranty which isn’t something that you may get from other waterproofing products. Rub-R-Wall has a slightly different application method.

It needs to be applied by certified installers, therefore, you can spray it by yourself. This may seem a bit inconvenient but professional installation guarantees that the waterproofer will be applied correctly.

According to the manufacturer of Rub-R-Wall, this waterproofing product can last for more than 100 years. The membrane created is said to be so tough that it can withstand heavy abuse.

The Rub-R-Wall waterproofing membrane is highly elastic. This is quite good because that’s an indication that it can resist shrinkage and crack. The adhesion offered by this waterproofing is super strong.

Apart from their waterproofing, Rub-R-Wall also has a wide range of coatings such as GrayWall waterproofing and PPD Professional Pride Dampproofing.

This wide availability of formulas is a characteristic shared also by Drylok. And it allows you to pick a formula that’s more specific to your current situation.

5. RadonSeal

If you have been sealing basements for a while, then you should be familiar with RadonSeal. This is one of the oldest waterproofing products on the market.

It was first launched in 1997 and ever since it has been used by professional contractors and DIY enthusiasts as a masonry waterproofer.

Radonseal is an ideal Drylok alternative. It can be used in basements in both residential and commercial properties. It is an eco-friendly option that can prevent moisture entry in garage slabs, chimneys, pool decks, patios, and even driveways.

If you are tired of musty odors in your basement and you can’t find some Drylok, you should inquire about RadonSeal. With RadonSeal, you can deal with mold issues once and for all.

6. Behr Waterproofer

Behr waterproofer and masonry sealer is made using silicone which gets deeper into your floor and walls, before drying into a strong membrane. Behr waterproofer was formulated to help homeowners prevent the effects of water damage within the foundations.

Just like Drylok, Behr waterproofer has a natural finish. A gallon of Behr waterproofer can be used on an area of up to 250 square feet. This is way more than Drylok’s coverage which is 100 square feet per gallon.

Behr waterproofer isn’t only affordable but it’s widely available. You can get it in most Home Depot outlets. These are more reasons why you should use it as a Drylok alternative.

Even though it’s a suitable alternative, Behr doesn’t do well in high-pressure areas. You should avoid using it if the area experiences heavy rainfall and strong winds.

The application of Behr waterproofer is pretty straightforward. You don’t need a primer or any adhesive. Just make sure you remove any contaminants and old sealants before application.
