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:

      Try the Super Seal 30. Hopefully, the Diamond Clear has not turned milky white. If it has, you will need to strip it off.

  17. Marshall Beere says:

    I live in park city, Ut.. I have a stamped concrete driveway. I would like to seal it. It was sealed 4 years ago but I believe the sealer has completely worn off. Can I spray a sealer on it or do I have to roller it. Spraying seems morlogical since it would more evenly get into the stamped indentations. What sealer would you recommend?

  24. Carol says:

    Kentucky, exterior, horizontal, no change of appearance, flat slab serves as a roof over a garage. Built in 50's. Does not appear to have ever been sealed. Numerous cracks, many were sealed with a caulk 10 or more years ago. Slab is 2 layers, base is about 5" thick, second layer on top is about 2 1/2". There is a crack underneath (in the garage) running the length of the garage, which leaks with rain, small stalactites have formed over the years. No crack directly above this crack. Suspect water is running down a crack, then moving horizontally between the slabs, to the lower crack, then leaking into the garage.

    Need to know the best way to seal the cracks, then seal the entire surface (about 330 sq ft). This is used lightly as a patio, mostly by my dog.

    • Concrete Sealer Help says:

      You should fill the cracks with an epoxy type crack filler for concrete. Seal after with Masonry Saver Heavy Duty Water Repellent or the Super Seal-M.

      What type of concrete surface is this? Wet look and gloss sealers will not work for plain poured white concrete. Dries blotchy.
