Understanding The Pros And Cons Of Waterproofing Paints

Posted on: 21 September 2015

A flooded basement is a nightmare. Basement waterproofing is an important step in protecting your home from this type of damage. Waterproof paint is a popular protective addition. Waterproof paints are designed with a concrete, oil or latex base that works as a barrier to prevent water seepage and excess moisture out. It is installed much like a traditional paint coat and lasts a considerable amount of time. Familiarizing yourself with the pros and cons of this waterproofing technique can help you determine if it's right for you. 


If you have ever been in a basement and smelled a mildew or fungal type of scent, you know firsthand that this scent is anything, but appealing. One of the advantages of waterproof paints is that it can help prevent the smell from consuming your basement. Even if there is a mildew or fungal buildup around the exterior of the basement walls, the concrete, oil or latex base in the paint coat creates an airtight seal that prevents the smell from penetrating inside.

Waterproofing paints can also help lower your problems with humidity. Even if you aren't dealing with a flooded basement, humidity is often a struggle for some homeowners when it comes to their basement. Humidity can make a place uncomfortable and at high levels can even damage certain appliances and electronics. Waterproofing paint blocks the moisture behind the painted surfaces and reduces the radiation level at which humidity is able to come inside.


Most of the cons that surround waterproofing paints arise when a homeowner thinks waterproofing paint is an inclusive solution. As mentioned before, waterproofing is a protective addition. It is not intended to work alone. The primary goal of waterproofing paints is to plug or hold moisture. It can't actually prevent water from entering into your basement.

You should be addressing the manner in which water is entering the basement first and then using waterproofing paint as an additional layer of protection. Another concern is hydrostatic pressure or water pressure. Most foundation walls have hollow cavities. When moisture is present within these cavities it fills up the spaces, putting pressure on the foundation. Since waterproofing paints are intended to hold back moisture behind the walls, it can actually cause an excessive buildup of moisture within your foundation. Overtime, hydrostatic pressure can lead to foundation failure.

To get the most benefit out of waterproof paint, it's best to rely on the knowledge of a waterproofing professional. A professional can first address the cause of water inside your basement and create a multilevel waterproofing technique to protect your home.
