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.

    • 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.

  15. Dale Ensslin says:

    I'm looking to seal a concrete porch deck which was re-surfaced with wire and cement three to five years ago. The home is located in eastern Pennsylvania. There are areas of fine hairline cracks already showing.
    What would be the best sealer to help my customer obtain the longest life possible; knowing full well the area of fine cracks is already compromised.

      The Super Seal 30 will work for the stamped. Gloss sealers do not work well on regular poured concrete. They dry uneven or blotchy. Look at a non appearance changing sealer like the Super Seal M Water Repellent.
