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.

    Broom finish patio that has had a semi transparent stain applied

    We also have a natural stone wall 2 feet high around patio that has a sand stone top as a sitting area around the top of wall. Could same product be applied to seal concrete patio and sand stone?
    Do you recommend shark additive to a broom finished patio?
    Thanks

    3. 80% horizontal. 20% vertical.
    4. Wet look. Although doesn't have to be a deep/intense set look. A bit darker/deeper than when dry would be acceptable as well. Don't need high gloss. Will be around a chlorine pool. Stairs to pool, and large cement wall around pool deck.
    5. 70% new concrete and 30% old concrete. All will be acid stained with "camouflage concrete, artist grade acid stain".
    Key consideration is ease for future reapplications. The area to be convered is huge! (estimate 5,000 SF) and no way we want to have to remove in future years before reapplying something.
    thank you!

    • Concrete Sealer Help says:

      Use a product like SuperSeal 30. Use a grip additive that they make called Super Grip.

      • Ed s says:

        Is this for the stamp concrete walk way or the pool surround that is just an old poured slap. Please recommend the solution for the second project.
        1. stamp concrete walk way in front of house

        2. pool surround that is a 30 + year surround the pool

        Where is a good place to order the products? I really appreciate this help.

        This is a great service thanks.

        • Concrete Sealer Help says:

          1. For stamped walkway look at SuperSeal 25
          2. The pool surround should not have a gloss sealer. More a penetrating water repellent like the SuperSeal M.

    4. Primary goal in appearance: DARKEN – I like the darkness of the pavers and capstones when they are wet. Regarding SHEEN: I would prefer a matte or low-gloss finish, but would accept a high-gloss finish if that were the only way to get a darker appearance. Additionally, I would like a product RESISTANT TO STAINS such as melted chocolate and red wine.
    5. Fire-pit kit made of concrete block pavers, with smooth-finished concrete capstones. New; installed July 2, 2014, and exposed to weather since. Untreated as yet.
