10 Best Waterproof Basement Paint 2026 in the United States

The Drylok Masonry Waterproof Clear 5g (DRYLOK - 20915) is a clear coating designed to offer waterproofing for basement walls and other masonry surfaces. One of its primary strengths is its high waterproofing ability, which is crucial for maintaining dry, usable basement spaces. It also boasts strong mold and mildew resistance, an important feature for areas prone to dampness and humidity, helping to ensure a healthier environment.

With a high gloss finish, it provides a visually appealing look while protecting surfaces. Its durability in high-traffic areas may be a concern, as clear finishes can sometimes wear down more quickly than opaque coatings. The product is relatively easy to apply, but given its air-powered application method, you might need specific tools, which could add to the complexity for some users. Coverage is good, with one 5-gallon container covering a substantial area, making it cost-effective for larger projects.

The product is quite heavy at 46 pounds, which might be a consideration for ease of handling and application. Additionally, its international origin (China for packaging, though referenced as USA for the product) might be a point of consideration for those preferring domestically produced goods. If you need a reliable waterproof solution for your basement with a clear finish, and have the tools or can manage the weight, this product could be a solid choice.

The Liquid Rubber Concrete Foundation and Basement Sealant is a highly versatile waterproofing product suitable for both indoor and outdoor use. It offers strong waterproofing ability with a highly flexible membrane that can stretch over 900%, preventing cracks and tears. Its easy application process is a significant advantage, as it requires no mixing and can be applied with a brush, roller, or sprayer.

The product is also environmentally friendly, water-based, and free from harmful solvents and odors, making it safe for use around humans and pets. Whether you are sealing foundations, basements, or other structures, this sealant provides a protective finish and can be used with additional Liquid Rubber products for enhanced durability in areas with potential movement or gaps.

However, it's important to note that the product comes in black, which might not be the preferred color for all users. Additionally, while the product is marketed as easy to apply, users without prior experience in applying sealants may still find the process somewhat challenging. The coverage may vary depending on the surface type and condition, so it is advisable to calculate the required amount carefully. This product is ideal for homeowners and DIY enthusiasts looking for an effective and safe waterproofing solution for their concrete or wooden structures.

The TUFINEIN Rubber Liquid Waterproof Sealant is a versatile product designed to create a flexible, durable waterproof barrier, making it suitable for basement waterproofing and other leak repairs around the home. Its rubber-based formula forms a flexible rubber coating within 2-4 hours, which can stretch and cover small cracks, effectively preventing water infiltration.

This sealant performs well in extreme temperatures, ranging from very cold (-40°C) to quite hot (80°C), without cracking or breaking down, providing long-lasting weather resistance. It is reliable for use in both indoor basements and outdoor areas such as roofs and gutters. Application is straightforward, allowing use with a brush, roller, scraper, or by pouring, and it self-levels to create a smooth finish. Coverage is approximately 2 square meters at a thin layer for vertical concrete surfaces, though thicker layers reduce coverage area.

The product is not suitable for surfaces that will be walked on after curing. While it effectively seals water and moisture, it does not specify mold or mildew resistance, which may be a consideration for particularly damp environments.
