Best Concrete Sealers2017 is here and time to review and apply a new concrete sealer. This article is one of our top articles related to concrete sealers and there has been over 2100 Comments and Questions. If you need advice on What is the Best concrete Sealer for you, please ask below in the comment area.

Concrete comes in many different types and substrates that can be found both for both interior and exterior applications. There are Concrete Driveways, Vertical Brick Walls, Brick Paver Patios, Basement Floors, etc. Concrete is very porous and can be prone to degradation from Water, Ultra Violet Radiation, wear, and tear, etc. By sealing or waterproofing your concrete surface you will add life and protection to your surface.

So what is the Best Concrete Sealer?

The answer to that is dependent on why you are sealing, what surface you are trying to seal, and what your final expectations are.

There are many different types of sealers for concrete and masonry surfaces. Concrete sealers come in both water based and solvent based formulas. They come in generic formulas for all surfaces or formulas that are specific to the surface you are applying to. For example, you would want a Brick Paver Sealer for a Paver Patio and a Chimney Sealant for your Chimney but you could use MasonrySaver All Purpose Water Repellent for both.

So why seal your concrete or brick? The main reasons to seal and waterproof your concrete are:

1. Preventing hairline cracks due to water expansion during freeze/that cycles.

2. Prevent water penetration and seepage of water through walls and foundations.

3. Enhance the appearance by adding a gloss or darkening the overall color.

4. Prevent damage from deicing salts during winter months.

5. Provide protection from “Pitting” or “Spalling” or deterioration of the concrete causing chunks of the concrete to separate from the concrete structure.

Once we understand the surface we are treating and what the reasons we are treating the surface for, then we can narrow down what would be the best concrete sealer to use.

Here is an example of concrete surface in Florida (answers in Red):

1. What State do you live in? Florida

2. Interior or Exterior concrete surface? Exterior

3. Vertical or Horizontal application? Horizontal

4. Change or enhance appearance (gloss or wet look) or no change of appearance? Wet Look/Gloss

5. Type of surface examples: Driveway, Paver Patio, Brick Wall, etc. Paver Driveway

Based on the answers you would want a sealer that is specific to brick pavers, gives excellent UV resistance since it is in Florida while adding a shiny enhanced look. Based on these questions you would want to look at:

  • SuperSeal25
  • SuperSeal30
  • MasonrySaver Paver Sealer.

Feel free to answer these questions for help choosing the “the best concrete sealers for me”. Just post a comment below and based on your answers, we will suggest a couple of different options of what sealant or water repellent you should use:

      do you already have a sealer on the stamped concrete that has bubbled?

      • Michelle Katz says:

        Hello – I'm having the same issue. I just had my entire back patio stamped and stained to look like wood. The guy told me he would need to come back in a month to reseal and make sure the stain was protected. He's been back 3 times to reseal and each application of his chemical based sealer bubbles and looks terrible and I'm beginning to think my deck is ruined. Last round he used xylene as a sealer and it bubbled, again. My friend is a contractor and he's recommending to have it fixed using a water based sealer – is this an option? If so, which would you recommend and is it something that can go on top of the chemical sealer and hopefully fix the problem?

        • Concrete Sealer Help says:

          FYI, xylene is a solvent, not a sealer. You cannot add another product on top of this issue to fix. It needs to be chemically stripped of the coatings first so it is down to the bare concrete. After it is stripped, do a final prep with a general concrete cleaner degreaser. Once fully removed, try the Masonry Saver Decorative Concrete sealer. For the stripper, we use Clemons Concrete Sealer Stripper. You may need to strip a few times to remove the 3 layers.

    Paver Patio (Nantucket Berkshire)

    Last year in August I applied Supreme Shield SB 600 on this patio, partially based on the high rating on this site. It looked great for 3 days, although I thought it was surprisingly glossy. Then we had a very light rain and white spots appeared immediately, albeit only in small areas at first. Now, 8 months later, the patio looks almost uniformly horrible. The only part that looks ok-ish is a 10-inch strip along the side of the house where the patio is somewhat sheltered from rain. Everywhere else the sealer basically peeled off, as if someone had tried to remove it with sand paper and given up halfway through the process. In many places I can scrape off the sealer with my fingernails. There is only very light foot traffic on this patio.

    I am not exactly sure what to expect from a "penetrating" sealer, but if I had to guess I'd say the problem is that this sealer failed to penetrate the pavers.

    Obviously I'll have to remove what remains of the Supreme Shield and apply a different sealer — I am thinking water based this time. I'd be grateful for any suggestions, both on how best to remove the Supreme Shield and on what sealer to choose for my next attempt. Thanks!

    • Concrete Sealer Help says:

      Supreme Shield is a penetrating sealer and does not peel or show gloss when done correctly. The only way this could possibly happen is if it was applied over top of another sealer or excessively over applied resulting in the sealer not being able to penetrate. Strip and remove all coatings with Clemons Concrete Sealer Stripper. You might want to contact Clemons for advice on what happened to the Supreme Shield.

      • Peter says:

        Thanks for the response! I used a little over a gallon of Supreme Shield on 120sqft of pavers, and this was the first sealer applied to the pavers since they were installed. Of course I don't know what happened to the pavers before I bought them that might have prevented the penetration. You're right, I should contact Clemons and the manufacturer of the pavers for advice.

        If I wanted to try a water based sealer after I clean up the Supreme Shield, which brand would you suggest?
