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:

      Look at Masonry Saver Heavy Duty Water Repellent.

        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.

      Look at Masonry Saver Heavy Duty Water Repellent.

    Florida
    Exterior
    Vertical
    Wet Look or Satin
    Chiselwall Concrete 4×12 brick retaining wall

    Rough Chiselwall surface and some small areas so best to apply by brush…

    • Concrete Sealer Help says:

      For a wet look, try Supreme Shield SB-600. You may need a fee coats though due to the porosity of this surface type.

    I'm interested in purchasing the best Sealer/Cover for a Pole Barn Floor, 30'x56"? More interested in Protection then looks! I was told that it should be done as soon as you can walk on it? Was considering Rolling it on with a Wide roller? I was also WARNED to make sure that the coating doesn't break down/leak when Chemicals come in contact with it?
    I live in Northern Michigan with cold winters & the floor will probably have snow on it from tracking in & the possibility of water from the melting? Will probably heat the Pole Barn sometimes? All help would be Very Much Appreciated!
    With Kind Regards.

    I live in Florida. Water seeps in between my slab and concrete block walls. What is the best interior sealer for this issue?

    • Concrete Sealer Help says:

      A sealer will not fix and issue like this. The issue is more between the two areas. Large cracks, etc and needs to be fixed from the outside, not the inside.

  5. Herbert says:

    Do you receive any compensation from the sealer manufacturers when readers click on their links? I read an article saying a lot of web sites for "Best carpet" or "Best mattress" etc, get compensation from the manufacturers for every user that clicks a link to visit the manufacturers site. Not that they are necessarily biased. But I'm curious if you receive any funds from manufacturers.
