Drylok vs Zinsser: Quick Comparison

 Drylok and Zinsser Primers for Protection


The formula of Zinsser and Drylok is the first notable variation between them.

First and foremost, both of these primers are acrylic. Acrylic concrete sealers provide several advantages, including good moisture protection, quick drying time, and a variety of colors to enhance the appearance of the surface.

Again, both of these primers are based on oil. As a result, these primers outperform oil-based sealers in terms of raw performance.

But Zinsser also provides a latex-based paint as an extra option, giving clients more options.

Latex-based paints cure faster and are less harmful to the environment.

Surface Compatibility

Surface compatibility is critical because different primers behave differently depending on the surface. Both Drylok and Zinsser provide a wide range of surface compatibility in this regard.

Depending on the surface, you must decide whether you want an oil-based or latex-based primer.

Drylok works with regular stuff such as cement and concrete surfaces and unusual surfaces like porous terra cotta and stucco. On the other hand, Zinsser can be used on various surfaces, such as an uncoated basement, retaining walls, cellar walls, and concrete subfloor.


This is one of the most significant distinctions.

Drylok and Zinsser’s waterproofing abilities will influence people’s purchasing decisions.

Zinsser appears to be the better option in this regard. It claims to endure water pressure ranging from 10 to 34 pounds, depending on the painted model.

Zinsser also offers mildew and mold control in addition to waterproofing.

On the other hand, Drylok only prevents water from entering your structure. Unfortunately, the primer does not prevent mold or mildew.


The ease of application should be a primary consideration when buying any primer. You don’t realize how important this is until you run into problems in your DIY projects. In this aspect, Drylok appears to be slightly superior to Zinsser.

While applying Zinsser can prove to be overly calculative with a roller or brush at a specific temperature range. This is not the case when using Drylok.

Drylok can even be applied with a sprayer, which is impossible with Zinsser.


We don’t refurbish, paint, or seal the concrete surfaces in our immediate environment daily. That is why it is critical to examine the element of longevity.

Overall, Zinsser appears to be the best option in this segment.

Zinsser models guarantee waterproofing and mold prevention for 5 to 20 years. On the other hand, Drylok offers a 7 to 15-year guarantee.

Zinsser, thus, appears to be the preferable option if you want to safeguard your concrete surface for years to come.


Added features come at an additional fee. As a result, the price of these primers may become a decisive issue for certain people. Zinsser will be significantly more expensive than Drylok in this sense.

The Drylok might be a better option if you’re searching for basic protection for a DIY project.
