Drylok Vs. Flex Seal: Waterproofing Face-Off
Cost-effectiveness
When comparing the cost-effectiveness of Drylok and Flex Seal, it’s important to consider the scope and scale of the project at hand. Both products offer their own advantages depending on the size and nature of the waterproofing task.
Drylok for Larger Projects
Drylok is an ideal choice for larger projects, such as waterproofing entire basements. It is generally more cost-effective for these extensive applications due to its larger coverage area per gallon (Stickyn). This makes it a favorite among budget-conscious homeowners and contractors who need to cover a substantial surface area.
| Aspect | Drylok |
|---|---|
| Coverage Area per Gallon | 75 – 100 sq ft |
| Cost | $25 – $30 per gallon |
| Ideal for | Large-scale waterproofing projects |
Using Drylok for larger projects means reducing overall costs significantly. It’s designed to cover more ground, making it an economical option for spaces that require thorough and extensive waterproofing (Stickyn).
Flex Seal for Targeted Repairs
Flex Seal, on the other hand, is more suitable for quick, targeted repairs. Though Flex Seal can be pricier per application, its ease of use and effectiveness in small, precise areas make it a popular choice for minor leaks and touch-ups.
| Aspect | Flex Seal |
|---|---|
| Coverage Area per Can | 12 – 15 sq ft (per spray can) |
| Cost | $12 – $15 per can |
| Ideal for | Quick, targeted repairs |
Flex Seal excels in convenience for smaller tasks where immediate waterproofing is required. Its spray can format allows for quick application, making it ideal for dealing with emergency leaks or small-scale waterproofing issues efficiently (Stickyn).

Effectiveness Comparison
When comparing Drylok vs. Flex Seal in terms of effectiveness, it’s essential to consider their distinct functionalities and how they perform in various situations. Here’s a detailed view of both products:
Drylok’s Impenetrable Coating
Drylok is highly effective at creating an impermeable seal against water infiltration. It penetrates the tiny pores of surfaces, making it particularly useful for preventing water leaks in basements, by forming an invulnerable coat. It is typically applied to large areas such as walls and floors to prevent water from seeping through foundations.
| Metric | Detail |
|---|---|
| Primary Use | Large-scale waterproofing (e.g., basements) |
| Application Area | Interior walls, foundations |
| Penetration | Deep pore penetration |
| Durability | Long-lasting |
According to MyInteriorPalace, Drylok stops water from seeping through interior walls and foundations by forming an impenetrable barrier. Its effectiveness is evident when applied correctly and in multiple coats. For more insights on adhesives suitable for different conditions, see is JB Weld waterproof.
Flex Seal’s Temporary Solutions
Flex Seal is versatile, serving as a liquid rubber sealant for various DIY projects. While it can cover and protect multiple surfaces like concrete, tiles, metal, drywall, aluminum, glass, and rubber (MyInteriorPalace), it is best suited for targeted repairs rather than extensive projects. This makes it ideal for sealing specific leaks and cracks, such as a leaky roof, temporarily.
| Metric | Detail |
|---|---|
| Primary Use | Targeted repairs |
| Application Area | Specific leaks and cracks |
| Versatility | Works on various surfaces |
| Durability | Temporary |
Flex Seal excels at sealing specific cracks or holes that allow water to enter, serving as a provisional solution until a more permanent fix is implemented. If you’re looking for more adhesive comparisons, consider reading about leak stopper vs. flex seal and plasti dip vs. flex seal.

Compatibility Concerns
Not Recommended Together
When considering waterproofing solutions, it is important to understand the compatibility of different products. In the case of Drylok and Flex Seal, it is not recommended to use them together. This recommendation stems from their differing chemical compositions, which could lead to poor adhesion or ineffective results. Both products require proper surface preparation to ensure optimal performance (Stickyn).
Potential Issues
Using Drylok and Flex Seal together can lead to several potential issues:
- Poor Adhesion: The differing chemical compositions of Drylok, a cementitious product made of cement and latex or oil-based paint, and Flex Seal, a liquid rubber sealant, can cause poor bonding when applied on top of each other.
- Ineffective Waterproofing: Drylok does not bond well to concrete, which is crucial for effective waterproofing. Mixing it with Flex Seal can further exacerbate this problem.
- Surface Preparation Issues: Different surface preparation requirements for Drylok and Flex Seal can lead to complications. For example, Drylok is not intended for surfaces that experience foot traffic or hydrostatic pressure, while Flex Seal is designed for more targeted applications (SANI-TRED).
It is essential to choose the right product based on the specific needs of your project and to avoid mixing products with incompatible properties. For more insights on similar topics, visit our articles on flex paste vs. flex seal and leak stopper vs. flex seal.
Durability and Warranty
When deciding between Drylok and Flex Seal for your waterproofing needs, it’s important to weigh the durability and warranty of each product. Below, we explore the warranty periods and resilience of both Drylok and Flex Seal, helping you make an informed choice.
Drylok’s Warranty Periods
Drylok offers several products with different warranty periods, ensuring peace of mind for long-term projects. Here is a breakdown of the warranty durations for specific Drylok products:
| Drylok Product | Warranty Period |
|---|---|
| DRYLOK® Original Masonry Waterproofer | 10 Years |
| DRYLOK® Extreme Masonry Waterproofer | 15 Years |
| DRYLOK® Floor & Wall Masonry Waterproofer | 7 Years |
These warranties are applicable when Drylok is applied according to the specified directions on properly prepared bare masonry surfaces. Notably, the warranty coverage extends to subsequent owners, making it an attractive option for property resale.
Flex Seal’s Resilience
Flex Seal is known for its fast and effective temporary waterproofing solutions. Unlike Drylok, Flex Seal does not specify a warranty period but is widely praised for its resilience in providing quick fixes for leaks and cracks.
Flex Seal’s performance is most effective for targeted repairs and short-term applications rather than long-lasting solutions. For more comprehensive protection, users may want to consider alternative or supplemental products. For instance, Sani-Tred offers a lifetime warranty, ensuring permanent waterproofing and protection against water and negative hydrostatic pressure.
