Guide to Buying the Best Product

When shopping for paint for your exterior foundation walls, it often comes down to these three things.

Elongation

The best way to understand elongation is to think about what happens long after you’ve applied your paint. Elongation ensures that the coat continues to fill gaps and crevices, providing waterproofing and mold resistance. The best paints have elongation between 900% and 1100%

Cost

Cost is an issue for most people when shopping for paint, and it should be for you too. The common conception is that you need a lot of money to get a good product but that’s not always true. We found great paint that was very affordable but offered a ton of value.

Self-priming

Self-priming means that you can use your paint without a primer. This is important because it gives you less work to do. Self-primed paints are easier to apply and cost less than paint and primer would. If you can, we highly recommend going for these kinds of paint.

Top 15 Best Paint for Exterior Foundation Walls

So now you know what to look out for. Let’s dive into all the products we found during our search. You’ll notice that we handpicked these based on the information we shared in the guide.

KILZ Interior/Exterior Basement and Masonry Waterproofing Paint

Buy from Amazon

We know the topic says exterior paint, but we couldn’t resist showing you this multipurpose product. It works for both interior and exterior applications, and it’s specially formulated to waterproof and seal concrete that’s otherwise porous. How you ask? Nanotechnology of course.

The paint is designed to form a barrier that stops water from infiltrating surfaces. At the same time, an alkali-resistant coating that’s mixed in with the formula delivers a long-lasting and durable finish. We love the paint because when applied properly, it can work on retaining walls, cinder blocks, concrete, and even brick.

Liquid Rubber Concrete Foundation and Basement Sealant

Buy from Amazon

This liquid rubber sealant is available in a regular size of 1 gallon and a jumbo size of 5 gallons. That’s great if you’re looking to apply it on a large expanse like basements, shower liners, or planter boxes. It also works great on wood, metal, concrete, and fence posts.

As expected, it is highly flexible with over 900% elongation and can cover 50 sq ft per gallon of coat. The paint is also easy to apply because you don’t need any mixing. You can simply use a brush, roller, or paint sprayer. You know how some paints can be used on the outside and inside of your home? This is one of them and it happens to be environmentally friendly.

Micro blend Exterior Paint and Primer

Buy from Amazon

We don’t recommend anything but the best paint for your exterior foundation walls, which is why we are thrilled to show you this product. It has a micro blend with professional quality, low VOC, and odor. But that’s not all! The Micro blend Exterior Paint also delivers a silky smooth, luxurious finish.

The paint also has stain blockers and rust inhibitors that help keep the surface pristine and shiny. You’ll also get the Micro blend patented formula that keeps the color as consistent as the time it left the factory. Did we mention that this paint comes in 40 different colors? You’ll definitely find one to fit your home.

INSL-X AMW100009A-01 WaterBlock Acrylic Masonry Waterproofer Paint

Buy from Amazon

Are you worried about mold and mildew in your foundation walls? Moisture can accelerate the progression like you would not believe. But don’t worry because as long as you have a coat of this paint, you’re safe. Besides resisting mold and mildew, the INSL-X paint is also highly alkali resistant and can withstand up to 12 psi of hydrostatic pressure.

The manufacturer recommends that you review the label for proper application and preparation tips. And if you’re buying paint as effective as this, it only makes sense to make every drop count. If there are any cracks on your application surface, use a concrete patching compound to set it straight before applying the paint.

FIXALL Skid Grip Anti-Slip Paint

Buy from Amazon

As the name suggests, this coat of paint has high grip, which makes it perfect for high-traffic outdoor areas. But that’s not all it’s good for. The FIXALL Skid Grip Anti-Slip Paint also adheres to most surfaces, so you don’t have to worry about compatibility. It works on wood, cement, stone, and even asphalt.

It’s great for everyone, even if you’re not much of a handyman. With a paint roller or brush, you’re good to go. Remember to clean the surface and remove any debris first. That way, you get the most out of the paint. The manufacturer offers five different colors, ranging from cobalt blue to emerald green.

Jetcoat Farm Pride Acrylic Outdoor Fence and Barn Paint

Buy from Amazon

A single coat of this paint is worth more than double some other products on the market. And we know price doesn’t always determine quality. But in this case, it does! Jetcoat Farm Pride Paint is water-based which really enhances its water-resistant properties. The paint is also fortified with UV inhibitors so that every coat will last as long whether it’s in the sun or under your roof.

You may be thinking, “why should I spend that much on a single coat?” Besides the fact that it’s quality stuff, a single gallon will also cover up to 100 square feet of space, and that’s before diluting! The Jetcoat Farm Pride is great for agricultural roofs, barns, fences, and silos.

AMES BMX1RG 1 Gallon Blue Max Regular Liquid Rubber

Buy from Amazon

This product’s title tells you everything you need to know about it. But you know us; we’ll tell you a lot more. For example, its liquid rubber formula makes it able to waterproof most surfaces, including wood, metal, and concrete. It also expands to about 1200% elongation while still resisting cracks and peeling.

We also love that the paint is non-toxic, eco-friendly, and VOC compliant. The one thing you have to remember with this product is to apply an even coat all over. Otherwise, you won’t get the full waterproofing benefits.

KILZ Interior/Exterior Self-Priming Masonry, Stucco and Brick Flat Paint

Buy from Amazon

As a savvy buyer, you’re asking yourself, “what does the KILZ interior/exterior paint do for me?” But our question is, what doesn’t it do? From providing excellent hiding for imperfections in your building to providing great water resistance. The paint is also highly adhesive and will work with almost any surface, whether it’s masonry, brick or wood.

It’s also self-priming so all you need to do is stick a brush in it and paint. However, you do need to shake it before opening it because it tends to settle at the bottom. As with all great foundation wall paints, it’s alkali resistant and can withstand a pH of up to 12. If you make a mess, you can also easily clean it with soap and water.

Leak Stopper Rubber Flexx Liquid Rubber Coating Paint

Buy from Amazon

One of our favorite qualities of this paint is that it’s affordable. But don’t take that to mean it’s cheap. On the contrary, it can give a lot of expensive coats a run for their money. Leak Stopper Rubber Flexx can be used for your home and office ceilings, floors, and walls. Besides being great for all surfaces, it can also be waterproof quite well.

Remember we mentioned that this paint delivers great value for money? Well if you aren’t satisfied with the value, you can even get your money back. The manufacturer offers a money-back guarantee on Amazon which is awesome!

Liquid Rubber Waterproof Sealant

Buy from Amazon

After reviewing so many products, we can instantly tell when paint is worth the purchase and when it’s just pure garbage. As you may have guessed, this one is worth the hype. It offers a protective finish for your home’s roof, floors, and basements. And it doesn’t matter what the surface is made of – wood, metal, concrete – it does the job all the same.

The membrane also has over 1000% elongation which makes it nice and flexible. This also means that it can stay stuck to all surfaces without failure. Add that to the UV resistance and you have a winning product. Even though it’s quite affordable, the Liquid Rubber Waterproof Sealant seems to be the gift that keeps on giving.

Gorilla Waterproof Patch & Seal Liquid

Buy from Amazon

The Gorilla Waterproof Patch & Seal Liquid doubles as paint even though its original purpose is something much tougher. As you can tell, it’s designed to seal out water, air, and moisture, separating it between one layer and another. It is also flexible and rubberized which means it can stop leaks, elongate up to 900%, and give your home a beautiful coat of paint.

The liquid is temperature and UV-resistant and will last for a long time once it dries. As with all great products, the trick is to apply them properly. With this one, you have to apply a thick enough coat that spreads out evenly. Also, be sure to use a primer before painting.

UGL 21613 1 Gallon Bamboo Beige Drylok® Latex Base Concrete Paint

Buy from Amazon

This bamboo beige-colored paint is perfect for your floors. But it has more than just the color to qualify. The paint is also anti-slip which means that it’s 100% safe. It’s self-priming and can be used on new or previously painted surfaces.

According to the manufacturer, it’s specifically designed for masonry floors but will work just as well with concrete. It is also flame and UV resistant so you don’t have to worry about applying a new coat every few months.

Vinyl Renu 5 Gallon-Siding Restoration Kit

Buy from Amazon

Even though you asked for an exterior foundation wall kit, we wanted to give you more value. Here’s a restoration kit that offers you a no-mess approach to waterproofing. The paint is also restorative and can make any old surface look new with a single coat.

The kit contains the paint, cleaner and Vinyl renu. These make it easy to clean up your paint stains even after they’ve dried. Each kit can also help you restore the siding and garage door of an average-sized home. That saves you a ton when you consider how many coats of other products you’d need to buy.

PRESTIGE Interior Paint and Primer

Buy from Amazon

Here’s another waterproof paint that does more than one job. We know what you’re thinking, and the answer is yes! It is water-resistant, environmentally friendly, and has low VOC. But what’s really exciting about this product is its primer quality.

Instead of making you choose among a preselected among preselected colors, PRESTIGE offers you a primer instead. That way, you can apply a second coat of your favorite color and the whole thing still turns out perfectly.

Conclusion

By now, you must have found the best paint for the exterior foundation walls that suits your needs. Before you go, we’d love to share some tips on how you can get the most out of your purchase. One important thing to remember is that water-proof foundation paint is usually expensive, and so, you want to get the best out of it. We recommend priming the surface first because it will save you a ton of paint later on. If your coat of paint is pre-primed, then grab a paintbrush and enjoy.
