Which is the Best Waterproof Paint? A Comprehensive Guide
Water damage can wreak havoc on both the interior and exterior of your property. Whether you’re looking to protect your walls, basements, or outdoor structures, using the right waterproof paint can make all the difference. With so many options available on the market, choosing the best one can be overwhelming. In this guide, we’ll explore the different types of waterproof paints, their applications, and what makes them stand out, helping you make an informed decision.
Understanding Waterproof Paint
Waterproof paint is specially formulated to prevent moisture from penetrating the surfaces it is applied to. Unlike regular paint, it contains additional additives that form a protective barrier against water, ensuring longevity and preventing the growth of mold or mildew. These paints are ideal for surfaces prone to moisture, such as basements, bathrooms, decks, and outdoor walls.
Types of Waterproof Paint
There are various types of waterproof paints, each designed for specific applications. Understanding the differences can help you select the best option for your needs.
- Masonry Waterproof Paint
This type of paint is specifically designed for concrete, brick, and stone surfaces. It penetrates the porous materials and creates a water-resistant barrier. Masonry waterproof paint is commonly used for basement walls, retaining walls, and other outdoor structures. It provides excellent protection against water seepage and is known for its durability. - Acrylic Waterproof Paint
Acrylic paint is a versatile, water-based option that is widely used for both interior and exterior applications. It’s highly resistant to water and dries quickly. Acrylic waterproof paint is often used on surfaces like concrete, wood, and drywall. It is popular for its smooth finish and is available in a wide range of colors. Its flexibility makes it a great option for walls, ceilings, and decks. - Epoxy Waterproof Paint
Epoxy paint is a two-part product made from a resin and hardener. When mixed, it creates a durable, high-performance coating that resists moisture, chemicals, and abrasion. Epoxy waterproof paint is most commonly used on floors in garages, basements, and industrial spaces, where heavy-duty protection is needed. Its ability to withstand high traffic and harsh conditions makes it a top choice for concrete floors and even boats. - Elastomeric Waterproof Paint
Elastomeric paint is known for its flexibility and ability to expand and contract with surface movements. This makes it an ideal option for outdoor surfaces that experience temperature fluctuations. Elastomeric waterproof paint can bridge small cracks and gaps, providing long-lasting protection against water. It is commonly used on exterior walls, roofs, and stucco surfaces. - Oil-Based Waterproof Paint
Oil-based paint is traditionally known for its superior adhesion and durability. It is water-resistant and can be used in areas that experience heavy moisture, such as kitchens, bathrooms, and exteriors. However, oil-based paints take longer to dry and may have a stronger odor than water-based alternatives. They also tend to yellow over time, making them less popular for interior use, but their waterproofing qualities are still excellent for certain projects.
Best Waterproof Paints for Specific Applications
To help you narrow down your options, here are some of the best waterproof paints based on their applications:
- Best for Basement Walls: Zinsser Watertite LX
Zinsser Watertite LX is a latex-based, low-VOC waterproof paint specifically formulated for use on interior and exterior masonry surfaces. It provides a mold- and mildew-resistant finish and can withstand up to 20 PSI of water pressure. This makes it one of the best choices for waterproofing basement walls, where moisture seepage is a common problem. - Best for Bathrooms: KILZ Interior/Exterior Basement and Masonry Waterproofing Paint
KILZ is a trusted name in the paint industry, and their Interior/Exterior Basement and Masonry Waterproofing Paint is a standout product for bathrooms. It creates a durable, mildew-resistant finish, perfect for damp environments like bathrooms. The thick, durable coating provides superior moisture protection, helping to prevent water damage. - Best for Decks: BEHR Premium DeckOver
BEHR Premium DeckOver is an acrylic-based waterproof paint designed to protect decks, patios, and other outdoor wood and concrete surfaces. It fills in cracks and provides a weather-resistant, non-slip finish. Its durable formula protects surfaces from rain, snow, and UV rays, making it a great choice for outdoor areas exposed to the elements. - Best for Roofs: Liquid Rubber Waterproof Sealant

How to Choose the Best Waterproof Paint for Your Project
When selecting the best waterproof paint, consider the following factors:
- Surface Material
Different paints are formulated for specific materials. Be sure to choose a paint designed for the surface you are working with, whether it’s wood, concrete, brick, or metal. - Indoor vs. Outdoor
If you are working on an outdoor project, look for paints specifically formulated for exterior use. These paints are designed to withstand UV rays, temperature fluctuations, and harsh weather conditions. Interior waterproof paints, on the other hand, focus more on preventing moisture damage and mold growth inside the home. - Durability
Some waterproof paints offer more durability than others, especially for high-traffic areas like floors and decks. Epoxy and elastomeric paints are known for their long-lasting performance in demanding environments. - Application Ease
Consider how easy the paint is to apply. Some waterproof paints require more preparation and multiple coats, while others provide excellent protection with minimal effort. DIYers may prefer options like acrylic or latex-based paints for their user-friendly application. - Environmental Considerations
For those looking for eco-friendly options, water-based paints like acrylic and elastomeric paints tend to be low in volatile organic compounds (VOCs) and are better for indoor air quality. Oil-based paints, while durable, often have higher VOC levels and take longer to dry.
Conclusion
Choosing the best waterproof paint depends on the specific needs of your project. Whether you’re looking to protect an interior wall from moisture, safeguard your outdoor deck, or seal a concrete floor, there’s a waterproof paint designed for the job. From the versatility of acrylic paints to the heavy-duty protection of epoxy coatings, each type offers unique benefits to suit various surfaces and conditions. By selecting the right product, you can ensure lasting protection against water damage and maintain the integrity of your property for years to come.
