5 Factors that Affect a Concrete Sealer’s Longevity

Anyone who has worked with concrete knows that longevity is a bid deal. Mixing and spreading concrete is a lot of work. It’s tedious, time-consuming, and expensive. No one wants high-maintenance concrete, so it’s important to set concrete up to last from the start to avoid big issues as little as a year down the road. Concrete is sensitive to wear and tear due to a number of factors, but your concrete sealer is what makes all the difference. It’s the difference between your concrete performing well for twenty years as opposed to five. So what do you have to look out for when it comes to making concrete sealers last? Tecnorap USA has five factors to consider to help improve longevity.

  1. Traffic: Concrete sealers typically sit on the surface of the concrete. This is an issue for a number of reasons, but most obviously it presents a problem because of traffic. Whether by car, foot, or otherwise, concrete sees a lot of traffic on a regular basis. This constant friction wears the sealer away, leaving concrete exposed and prone to damage. To counteract this issue, using a sealant that works beneath the surface is ideal.
  2. Moisture: Rain, snow, ice, car runoff: all these things flood concrete with moisture. Moisture is a sure way to weaken concrete, leading to cracks that get larger and larger. Cracks in concrete can become an expensive fix if left unattended too long and can even be dangerous in certain areas. The key is to use a sealer that stops moisture in its tracks 100% of the time.
  3. Temperature: After moisture, temperature may be the next most harmful threat to concrete sealers. The surface temperature when you apply the sealer is important. Once applied, sealers undergo a chemical reaction that causes them to cure and form a surface membrane. Ideally, they should be applied in 50 to 90 degrees Fahrenheit. However, if applied outside of this range, the sealer may not react properly or even at all. If the temperature is too low, the membrane won’t full form, and you’ll be left with a weak seal. If the temperature is too high, the sealer won’t apply correctly. You’ll end up with web-like strands and, again, a weak seal that won’t last.
  4. Deicing Salts: The salt itself doesn’t typically do much to a properly applied sealer. However, the problem lies in what the salts do. The purpose of a deicing salt is to melt ice. What does that leave you with? A lot of water. That’s a large volume of water resting on the concrete’s surface, and most sealers don’t keep every drop out. Once that moisture has found a way in, it can quickly damage the concrete. Wherever deicing salts are used, it’s recommended to stick to concrete sealers that work beneath the surface to stop moisture before it becomes a problem.
  5. Application: How you apply the sealer plays a big role in its longevity, and each sealer comes with a specific set of instructions that must be followed for maximum performance. You must use the right applicator, not apply it too thin or too thick, and get the application even. Otherwise, you’ll end up with bubbling and foaming, which don’t make for good protection.


All of these factors play a key role in your concrete sealer’s longevity. There’s one product, however, that lasts longer and is more durable than all other sealers, making it less susceptible to these common issues. Tecnorap USA’s Radcon concrete waterproofing is like no other sealer in that it works below the surface of concrete, protecting concrete from moisture from the inside and being unaffected by traffic.
