What is Waterproof Paint?

The waterproof paint is an oil or latex-based paint that prevents moisture penetration through a wall. Users can apply this paint on the wall by using the normal spray items like roller, paint brush etc.

After applying, it takes few moments to dry. Once it dries, this paint bonds with the concrete. It works just like an additional coating on the concrete.

The waterproofing paints can be used anywhere in the house. But, it’s most appropriate to use on stagnant water areas. For example, the basements, bathroom etc. Besides the common household areas, the waterproof paints also work great on the water tanks, birdbaths, and boat surfaces.

What are the Benefits of Using Waterproofing Paint for Concrete?

It’s true that we can’t live without water. But, unnecessary stagnant water causes mold and moisture problems in our house. In this case, waterproofing paint is the most effective and budget-friendly solution for every homeowner.

In this section, I’ve gathers few important benefits of using waterproofing paint on the concrete exterior.

Keeps Your Family Healthy

Mold and mildew are dangerous to our health. It causes lots of health problems like allergies, respiratory problems etc. So, it isn’t something that you can ignore.

But, if you use decent quality waterproofing paint on your concrete wall, you can stray free from all of these problems. These paints prevent mold, mildew, algae, fungus, or moss growth on the wall. Thus your family can stay safe and healthy as well.

Maintains Appropriate Humidity

Humidity is a huge problem for most homeowners. Especially if you live near New Orleans, Florida, Louisiana, or comparative humid areas, the humidity problem might be one of the worst nightmares for you.

These areas have around 80-86% humidity. On the other hand, the Environmental Protection Agency (EPA) recommends the people keep the humidity level below 60%. So, if you are struggling with humidity, you can apply waterproofing paints to watery areas.

These paints reduce the radiation level and block the moisture behind the painted walls. Thus, it reduces the humidity level in your house.

Easy to Clean and Last Longer

The waterproof paint layer very easy to clean. You will need nothing but plain water and soap for cleaning the surface. Thus, you can keep your walls sparkling clean with minimal effort.

Besides the ease of cleaning, the waterproofing paints also last for a long time. In most cases, an appropriate coating of the best concrete waterproofing paint will have an average lifespan of 10-15 years.

Budget-friendly

Waterproof paint costs much less compared to the other painting options. Besides the affordable price range, these paints are available in a variety of colors and preferences. Thus, you cannot miss the perfect color that suits your house the most.

Less VOC

VOC stands for “volatile organic compound”. Low VOC products are good for the environment, reduce air pollution, and tend to have a fresh odor. You know, waterproofing paints are also one of those low VOC products. Thus, it helps to make our environment a better place.

UV Resistant

The waterproof paints are UV resistant. So, the ultraviolet rays can’t cause any harm to your wall like cracking, peeling, or flaking. Most importantly, these paints can repair wall cracks around 3mm.

Make Your House Looks Aesthetic

Who doesn’t want to live in an aesthetic house?

If you also want to design your house more aesthetically, then it's high time to apply a layer of waterproof paint on the wall. Besides increasing the aesthetic beauty of your house, it also protects your house from water leakage, seepage, and unwanted liquid penetrations.

Increases Property Value

Having a waterproof basement and sub-floor is always a good selling point. You know, no one wants to buy a house with water leaking issues. So, the value of your property reduces automatically.

On the contrary, if you use waterproofed paints on your house, the house remains in tiptop condition for a long time. Besides, it represents that you’ve taken good care of this house. So, the value of your property increases drastically.

As you can see, it’s essential to make your house completely waterproof. This painting will not only make your house looks beautiful but also protects your family members from health hazards.

How to Apply Waterproofing Paint in Your Concrete?

In the previous section, I’ve discussed the benefits of using waterproofing paint on your house. Now, it’s time to applying the paint, right?

Let’s do it.

Things you’ll need

  • Paint sprayer
  • Waterproof paint
  • Paint brush
  • Stiff brush
  • Mortar
  • Soap etc.

Got everything? Let’s start painting like an expert!

Step 1: Checking for The Cracks

Unless you are going to decorate a new house, it’s pretty natural to find cracks on the wall. You know, the window and door frame area, ceiling joints, and the bottom sections are the weaker point of the walls.

You have to find out all of these cracks first and fix those ASAP. You may use good-quality fillers to repair the cracks.

Step 2: Cleaning the Wall Surface

After the fixing task is done, it’s time to clean the wall. You may use a stiff brush or scraper to remove wall coverings or old paints. Most of the users negligent in this cleaning section. Thus, they cannot get the most from their waterproof paint.

You must ensure that you have removed every single inch of dirt and make the surface completely spotless. For removing the stubborn dirt, use a mixture of soap and a clean water solution. Apply the solution to the wall and rinse after that.

Once the cleaning is done, don’t start the painting task immediately. Let the wall dry thoroughly before the painting. Remember, moisture is your #1 enemy while applying waterproofing paint.

Step 3: Patching The Holes

Using the waterproof paint on a wall with holes puts an end to the purpose of the painting. That’s why you must patch every single hole before proceeding to the paint applying.

After the patching is done, give it a day to dry completely. On average, it takes around 24 hours to dry. But, it mostly depends on the environment. It takes much less time during a sunny day in Florida than a gloomy day in Alaska.

To stay on the extremely safe side, you can apply a dehumidifier if needed. You know, the dehumidifiers work on the cell level to reduce moisture.

Step 4: Apply the Waterproof Paint

Here comes the most favorite part! Now, we will apply the painting to the wall. So, gather your waterproof paint, paint brush, sprayer or roller beside you. We will need these tools for this application.

Now, use the sprayer to spray paint on the larger areas. Make sure that you’ve sprayed paint equally on the whole wall. To paint the smaller areas or the edges, the paint rollers or paint brushes are quite handy.

By the way, you may require to apply an additional coating for a rough concrete surface. But, you can’t apply the second coating as soon as the first coating is done. Wait until the first coating has been dried completely, only then you are allowed to apply that second coating.

Pro tips: Use painter's tape on the edges to avoid unwanted color splashing where you do not want it to be.

Step 5: Testing the Paint Quality

Once you are done with the painting, it’s mandatory to perform a waterproofing test. However, this experiment is as easier as an apple pie. Spray water continuously on the wall for about an hour by keeping the nozzle at a 30-degree angle.

If you don’t notice any moisture after spraying for an hour, it means you have applied the paint appropriately and the paint is truly effective. But, if the test fails, you have to apply another coating on the wall. Hopefully, the paint will pass the test after applying the third coating.

 Yes! After a truly hectic journey, your house is completely waterproof now. Enjoy your living without worrying about water leakage.

How to Choose Right Waterproofing Paint for Concrete Wall and Basement?

Concrete Waterproofing Paint

When it comes to buying the best waterproof paint for concrete, your purchase decision will depend on your projects and requirements. It’s because all waterproof paints are not the same as each of them has its own purposes.

If you are not sure how to choose the right paint or what are things you must consider while purchasing it, check the information below.

The Color You Want

There are many concrete paints out there that are created with practical qualities. What I mean is that the concrete paints come in standard colors. When you are looking for paints that will deliver a pop of color, it will be much better to go for the brands that provide a wide range of different colored paints.

Go through their products and opt for the color that matches your needs. You will come across colors, such as grey, white and black, which are pretty common. Other colors that you encounter are blue, red, yellow, and many more.

Understand The Foot Traffic The Surface Will Take

Do you park your vehicle in the garage? Do you have mischievous kids? Then you need to check out how much foot traffic the painted surfaces can take.

Making these considerations is necessary so that you can buy a paint that will provide durability and will also carry stain-resistant properties. This will enable you to clean up all the dirt and spills from the floor, and prevent permanent stains or marks from taking place.

Whether The Surface is Exposed to Outer Components

The majority of the outdoor surface will be exposed to all the natural elements. When you have decided to purchase waterproof paint for your concrete surface, you need to see whether that area is exposed to all the outside elements.

Don’t just randomly choose a paint for the surface. Check the surface you want to paint and then make the decision of buying. Remember, buying a low-quality will wear off if the surface you have painted receives the most snow, UV rays, and rain.

Opt for Waterproof Paints

When you want to paint your concrete or cement surfaces, always opt for the paints that are waterproof. Opting for waterproof paint will hold back the water and the moisture from that particular surface. This will keep the surface from receiving any damage or issue.

You will come across many waterproof paints that are ideal for your concrete or any other surface, such as wood, masonry, and many more. They are available both in online and physical stores.

Make All the Repairs Before Buying

Before you even decide on purchasing the paint, you must repair and fix all the cracks on the concrete surface. Cracks on your concrete surfaces might be more than an unsightly annoyance. It’s because these cracks might indicate that there are some major structural issues within the foundation of the surface.

This is something that you fix before you apply the paint or sealant to it. Filling up the cracks will not deliver a smooth or plain appearance, but it will make it easier for you to paint it. You can either do the work on your own or call in the professionals to get the job done.
