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

    We used Valspar water based Concrete Stain 4 days ago and are unsure of what product to use to seal it to get our desired result. Local companies say it's impossible to get a very high gloss wet look on brushed concrete.

      I would look at the SuperSeal 30 for this but contact the manufacturer to be certain that it will work on your substrate.

    • Concrete Sealer Help says:

      No change will not work on colored concrete as they will not penetrate. Any sealer you can use on this type of substrate will enhance or change the look.

    • Concrete Sealer Help says:

      Glenn, do you just want a sealer with no change of look or do you want it to look darker like a wet look? I am thinking the former for this and would suggest the Masonry Saver heavy Duty Water Repellent.

  7. Wendy says:

    Best Concrete sealer? Ontario, Canada, interior, vertical, appearance not important, basement wall

    Prevent staining from muddy paw prints and make it easier to clean
    Wouldn't mind brown tint if that is an option with sealing. Shiny would be nice but not absolutely necessary
