The Best Waterproof Paints for Your Next Renovation

Renovation projects are time-consuming, require extensive planning, and cost significant money. It is not an easy process because there are many things to consider for each area. In addition, some locations will need extra measures to reinforce them against potential short- or long-term damage.  

Some areas that need special consideration are the bathrooms, basements, water tanks, and cement walls. They often need waterproofing to prevent water from seeping into them and potentially compromising other components.

What Is Waterproof Paint?  

It is either water-resistant or completely waterproof paint. It frequently has a base of oil, latex, or concrete, all of which can offer a robust impermeable seal. You can generally select the type of paint depending on where you place it and the amount of moisture it must withstand. You can use it on wooden or concrete surfaces within the building.  

Property owners typically use this paint as a sealing layer to protect basement or bathroom walls from leaks or humid conditions. It can help prevent water seepage and the ensuing harm to your building’s foundation when coated with cement basement walls. In addition, it also helps to avoid problems that can need pricey repairs.  

You can also use waterproof paints if you have a flat or green roof. You can coat the area to reinforce it so that water does not seep into the insides of the building. Excessive moisture can be dangerous because it can cause mould growth. So, next time you go up your wall-mounted ladder, you might consider using some for your roofing projects.  

Nevertheless, waterproof paint cannot resolve every issue. For instance, you still need to seal any gaps around bathroom fixtures or fractures in basement walls. You must apply it on clean, dry surfaces just like regular paints so it can adhere correctly. If required, you can use a dehumidifier to reduce the humidity for a few days.  

Types of Waterproof Paints  

Based on your unique demands, there are several types of waterproof paints that you can choose from for your project. Consider investing in waterproof paints to prevent water damage to your buildings and their exterior furnishings. The most frequent options are as follows:  

Masonry Paint  

Concrete, brick, and other hard surfaces within and outside a building are excellent for masonry paint’s adhesion properties. Using ceramic materials and latex, which stops most liquids from absorbing into the stuff, can make it waterproof.   

Moreover, these paints are mildew resistant and easy to clean with water and soap. Additionally, many masonry paints come with comprehensive manufacturer’s guarantees in case any issues occur due to a bad batch.  

Epoxy Paint  

Epoxy paints are a robust variety of waterproof paint utilized on equipment, tanks, and boats. These paints have potent ingredients that shield an object from water when submerged. Since they often don’t include solvents and keep their thickness as they cure, epoxy paints have a remarkable ability to seal. Some types are so resilient that you can even use water to apply them.  

Acrylic Paint  

The finest waterproofing paint for roofs and terraces made of rectangular blocks is acrylic paint, which provides excellent waterproofing solutions. You can ensure your roof’s longevity and water resistance by using this sealing solution and a primer together (irrespective of PH level). The elastic nature of acrylic enables the paint to shrink and eject water from the roof surface whenever it rains.  

Acrylic paints are simple and non-toxic, contrasting to other waterproofing options for a terrace. Using rollers, brushes, or sprayers, you can apply them to your roof surface. This roof waterproofing compound has the ideal qualities of being odourless and drying quickly.  

Acrolein Elasticized Paint  

You can apply acrolein elasticized paint to concrete surfaces to make them waterproof. Additionally, the substance prevents mould, bacteria, and other microbial growth caused by humidity. Acrolein is a hazardous chemical that, when inhaled, can irritate the throat, induce lung damage, and harm the skin.   

To make a waterproof material, mix this paint type with acrolein and reduce potential hazardous exposure. As of 2010, China is the only country that manufactures most of these paint brands.  

Choosing the Most Appropriate Waterproof Paint for Your Needs  

Whichever waterproof coating you require will depend on the surface type and location. It would help to consider whether it is a preventative measure or a response to an already present issue, the amount of moisture you have, and the aesthetic you want to create.  


You may need to apply anti-moisture or mould-proof paint to ceilings with moisture and condensation. It is typically due to high humidity in a kitchen or bathroom space. A nanoscale coating, which offers a clean waterproof wall layer for at-risk surfaces, may be beneficial for areas like a bathroom or kitchen where spillage and humidity are concerns.  

Basements and Garages  

These areas are among the most susceptible to moisture in a structure. Still, most people don’t waterproof them because they don’t need to be habitable places. Epoxy paint is an excellent selection for concrete because it is more durable than some of the other alternatives. It provides strong adherence to porous substrates and is extremely water resistant.   

For cellar walls, it’s crucial to use permeable paint. Another alternative is to tank the cellar, which involves applying a “tanking slurry” (a waterproof covering) to the walls and flooring to make the basement impermeable.  


Window frames and sills, exterior walls, skirting, and surfaces made of wood are highly susceptible to water damage. All types of specialized damp paints, finishes, wood sealants and weather shield products are appropriate as a water-resistant coating for wood.  

Skirting and Interior Walls  

First, you must decide whether the moisture results from the floor, the wall, or the environment’s humidity. A prominent indication of wetness is peeling wallpaper or cracking plaster and water on the skirting board. Additionally, you must determine the cause of the dampness: is it a leak, developing moisture, or inadequate insulation?   

If you don’t address the reason, you will constantly be dealing with humidity. If you damage the skirting board, you must first treat the wall beneath it before replacing the skirting. An acrylic waterproof paint for internal walls will also be effective against dampness.  

Exterior Walls   

Waterproof masonry paint is a popular coating for exterior walls. It preserves masonry from moisture and the elements and is available in various compositions, including Pliolite alternatives and thermal shielding. Although it stops external water from penetrating walls, it will not affect the existing moisture in the walls.   


Waterproofing your vulnerable spaces will take some professional input. It is risky to DIY your project when you know an expert can do a better job. It is the best move to let the professionals work with you on how you can tackle your setting better. Don’t forget to ask for explanations on procedures you are unfamiliar with because it will benefit you in the future.
