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.

    Need advice. Live in a condo complex in Kailua-Kona on the big island. We had a cement walkway put in about three years ago, and used a acid stone stain to color it Adobe brown. Over thr years the moss build up became a problem. We used a product called Wet it and Forget it. After it dried we realized it not only removed the moss but also most of the stain. So now we want to re-do the stain and seal the walk way. What do you recommend as a sealer for this project. Approx. 40 sq.ft.?Any information will be greatly appreciated. Thank you.

    • Concrete Sealer Help says:

      I cannot think of a sealer that would work for all scenarios that you have. Decorative concrete sealers will leave a shine of some sort. You usually cannot apply a penetrating sealer (no shine) to these surfaces as they will not work well. I would suggest contacting Saver Systems and see what they say may be your best option(s).

      Sealers will not stop 100% of moisture from coming up through the concrete. Not sure if what you are looking for will work well.

    • Concrete Sealer Help says:

      You have to fix the issue first and that requires heavy stripping and pressure washing. Use the Clemons Concrete Sealer Stripper. Apply a sealer over this will not fix the problem and will make it worse.

      Wet looks do not work on plain poured concrete. It will look blotchy when sealed. You can try it but it may not look good. SB-6000.
