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.

    To add to my comment a few minutes ago, it is a poured concrete patio. It cracked from 3 corners to the middle from last winter when it was only about 6 months old. With a health condition I am sensitive to bright lights and when the sun hits it I can't handle it. I thought of staining, but a sealer that would make it appear darker grey would be perfect, (or with a wet look would work). We brushed quik- crete into the cracks a couple times like the contractor advised. He also advised a good sealer and I am not sure where to get one.

    • 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.

    Wet Look, no Gloss
    Exposed Aggregate Pool Patio, ca. 2000 sq.ft

    • 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.

    I live in Oklahoma.

    I have a outdoor patio made of bricks (not brick pavers).

    I want a wet look, less shine, but the best protection.

    Anyone have a suggestion?

  14. 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 live in Central New York and would like advice on sealing exterior cement precast steps and a cement sidewalk. I would like the cement to remain natural with a non gloss look.
