What is the Best Concrete Sealer?

Best Concrete SealersConcrete 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 you 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.

    5. Type of surface examples: Concrete pavers (Artistic Pavers Coralock) pool deck. Salt water pool.

    • Concrete Sealer Help says:

      Andrew, just seal for protection but without any change or enhancement of the pavers?

      • Andrew says:

        Yes, we'd like to minimize the change to the surface appearance/color, but realize that SOME change is unavoidable.

        • Concrete Sealer Help says:

          Look at Masonry Saver Heavy Duty Water Repellent.

          • Andrew says:

            Thank you. Our contractor has recommended an H&C product, which he referred to as "deck sealer". It seems like H&C has a wide range of products, and I'm not sure exactly which one he's referring to. Would you recommend any of their products, and if so, which one?

            I asked him specifically about MasonrySaver/Defy, and he specifically warned me against it.

          • Concrete Sealer Help says:

            H&C makes average products in our opinion. Better then most anything you will find at a big box store but not as good as commercial grade products. Curious as to why he would warn against the Masonry Saver? Maybe because he has never heard or used it? Ask him which H&C product. It will probably be fine for what you need.

      • Andrew says:

        Yes, just seal for protection. We want any color change/enhancement to be as minimal as possible.

    • Concrete Sealer Help says:

      Has it been sealed before and if so do you know the brand?

      • Elena says:

        It has never been sealed, 19 years old. It started pitting. I would like to change appearance and refresh and protect from further damage. Concrete areas are separated by white plastic lines near the pool and wooden beams around the house.

        • Concrete Sealer Help says:

          I believe your best option would be the Surebond SB-6000 for this but I would contact the manufacturer to confirm.

      • Elena says:

        It has not. We need to rejuvenate the dull look.

    Anyone have a suggestion?

  13. Jason says:

    1. What State do you live in? Kentucky
    2. Interior or Exterior concrete surface? Exterior
    3. Vertical or Horizontal application? Both, but primarily Horizontal. Stairs up to a patio
    4. Change or enhance appearance (gloss or wet look) or no change of appearance? Dry look so I guess no change
    5. Type of surface examples: Not really sure of the type of concrete, I don't think it is exposed aggregate like the walk. (current seal looks to be "painted on" and is pealing) but there are bricks + mortar on either side of the stairs to make them look nicer and add a little width. One side of brick has started to separate from the steps.

    • Concrete Sealer Help says:

      Jason, you cannot fix a peeling concrete paint by adding a sealer on top. I am having a hard time picturing what this is exactly so I am not sure how to fix it. You probably need to remove the peeling paint fully first and that could be a challenge. Have your tried to call a local masonry concrete for a quote?

    I am hoping waterproofing the patio will prevent leaks into the basement during severe heavy rain & hurricane storms. Can the waterproofing be applied to an old patio?
    It should not result in a slippery surface when wet though.
    If the concrete is discolored, will the waterproofing product seal in those stains?
    Thank you!

    • Concrete Sealer Help says:

      Sealing will not stop water 100%. It may stop the majority though/ You would want to clean any discoloration before sealing. Look a SuperSeal M Water Repellent/

    • Concrete Sealer Help says:

      Tom, in our experience wet look sealers will not work well on fountains. Too much water will create a white haze.

    • Concrete Sealer Help says:

      That will not work with constant water on the surface of the fountain. Sealer will turn white in color. You can water proof but not darken or make glossy.

    Acid stained – love the color. Don't want to alter it
    Would like sem-gloss

    • Concrete Sealer Help says:

      Sealers that are semi-gloss will also darken the surface as if wet with water. You cannot get a semi-gloss without this. Look at the SuperSeal 25 or the Masonry Saver Decorative Concrete Sealer.

    • Concrete Sealer Help says:

      Look at water based sealer since it is indoors. Try Masonry Saver products. They have a Decorative Concrete sealer that will darken some and add some gloss.

    • Concrete Sealer Help says:

      Look at the Masonry Saver Decorative Concrete Sealer.

    5. Type of surface examples: Brick Wall

    • Concrete Sealer Help says:

      Try the Masonry Saver Brick Water Repellent. It soaks into the brick and reacts with the concrete forming an internal barrier. I am not sure though as to the affect on the mortar itself. I am assuming it would help but I would suggest contacting the manufacturer to be certain.

    • Concrete Sealer Help says:

      Sorry but no sealer will work in this scenario to 100% seal lava. Adding multiple coats will not work either.

      Sealers will not stop mold but may reduce it. Not sure what you mean my colored so that may change the type of sealer that will work. Can you explain?

  47. Bob from Pittsburgh says:

    I live in Pennsylvania and have a 4year old dyed, exposed aggregate driveway that is on a slope. I stripped and sealed my driveway in the summer of 2014 with 2 coats of SuperSeal 25 and added the gripper. The driveway looked spectacular upon completion. Recently, I left one of my cars on the driveway for about a week and the salt collected underneath the vehicle melted. I now see a white haze where the car was…is the sealant dissolving or is this simply the result of moisture. Is there something I need to do to continue to protect the concrete?

    Thank you Bob from Pittsburgh

    • Concrete Sealer Help says:

      Hard to say what the white is as it could be many things. I doubt it is dissolving the sealer though. When Spring comes, lightly clean the driveway and apply a solvent like Xylene or Lacquer thinner to the drive. It will restore the gloss and should remove the white spots. Essentially make it look like new. You can spray the solvent on with a pump sprayer. After this year, I would suggest resealing again in 2016.
