Concrete is a highly versatile building material that is used extensively in construction. However, one of its drawbacks is its susceptibility to water damage, which can cause it to crack, erode, and even crumble over time. To prevent this from happening, it’s important to apply a concrete waterproofing sealer. But with so many different types of sealers on the market, how do you know which one is the best? In this blog, we’ll take a closer look at some of the key factors to consider when selecting a concrete waterproofing sealer and highlight some of its benefits.

Factors to Consider

  • Type of Sealer

The first thing to consider when choosing a concrete waterproofing sealer is the type of sealer you need. There are three main types: film-forming sealers, penetrating sealers, and surface sealers.

Film-forming sealers create a barrier on the surface of the concrete, preventing water from penetrating. Penetrating sealers, as the name suggests, penetrate the concrete and create a water-repellent barrier from within. Surface sealers are applied to the surface of the concrete and work by filling in any small cracks or gaps, preventing water from seeping in.

  • Durability

Another important factor to consider is the durability of the sealer. You want a sealer that will last for a long time and continue to protect your concrete from water damage. Some sealers may last only a year or two, while others can last up to ten years or more.

  • Breathability

Breathability is another important consideration when selecting a concrete waterproofing sealer. You want a breathable sealer that allows water vapour to escape from the concrete. If water vapour is trapped inside the concrete, it can cause it to deteriorate over time.

  • Ease of Application

Finally, you want a sealer that is easy to apply. Some sealers require specialised equipment or multiple coats, which can make the application process more time-consuming and costly. Look for a sealer that can be applied easily with a brush, roller, or sprayer.

Benefits of concrete waterproofing sealer

There are several benefits of using a concrete waterproofing sealer, including:

  • Protection against water damage: The primary benefit of using a concrete waterproofing sealer is that it protects the concrete against water damage. When water penetrates concrete, it can cause it to crack, erode, and even crumble over time. A waterproofing sealer prevents water from penetrating the surface of the concrete, helping to extend its lifespan.
  • Reduced maintenance: By protecting the concrete against water damage, a waterproofing sealer can help to reduce the amount of maintenance required. It can prevent the need for costly repairs and replacements, saving both time and money in the long run.
  • Increased durability: A concrete waterproofing sealer can also increase the durability of the concrete. It can help to prevent damage from freeze-thaw cycles, which can cause concrete to crack and deteriorate over time.
  • Improved appearance: Some concrete waterproofing sealers can also enhance the appearance of the concrete. For example, some surface sealers can fill in small cracks and gaps, creating a smooth and uniform surface.
  • Protection against stains: In addition to protecting against water damage, some concrete waterproofing sealers can also protect against stains. This is particularly beneficial for concrete surfaces that are exposed to oil, grease, and other contaminants.

Bottom-line 

Overall, using a concrete waterproofing sealer is an important step in protecting your concrete surfaces and extending their lifespan. It can provide numerous benefits, including protection against water damage, reduced maintenance, increased durability, improved appearance, and protection against stains.
