What is the Best Concrete Sealer? 4.7/5 (70)

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 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.

      No that is not possible to add a penetrating sealer over a stained floor. It will need to be a filming type sealer if stained.

    • Concrete Sealer Help says:

      Try the Masonry Saver Heavy Duty Water Repellent. 10 years is not realistic, but this should get you 5-8 years.

  47. Arthur says:

    Stripping sealer off my stamped concrete pad. I've used the Clemson concrete stripper to remove sealer but i still have a few areas where the area seems to be some white stuff still there. My question is should I use the Clemons stripper to restrip the area or should I use some xylene to try and remove it and pressure wash after? I've used a string brush as well as with Clemons degreaser after i have stripped the sealer.

    • Concrete Sealer Help says:

      Xylene is not a stripper so that probably will not work. It is either remnants of the old sealer that did not come off all the way or residue from stripping that was not rinsed thoroughly off after stripping. If old sealer, you should use the stripper again and pressure wash. If residue from the 1st stripping, the Cleaner Degreaser should remove it.
