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.

    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!

        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.

        • 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.

      Karen, Super Seal Matte for this. A rich wet look and a low matte gloss.

      • Karen says:

        Are you referring to the product listed as SuperSeal-M Concrete Sealer (product code SS_M)? The description on the ordering page indicates "No Change in Appearance" as a feature of this product. I want to be sure my end result is a darker appearance.

      Sealers or water repellents will not fill or stop water from penetrating though cracks but will through the concrete. Try SuperSeal M Water repellent.

    Hi
    We recently purchased your Defy Extreme deck stain and were extremely impressed with the product and the speed of shipping as we live in Ontario Canada We have recently completed a boat port that sits on a 25 x 35' poured concrete slab. Approx 10 x 25 of the slab is outside and the remaining 25 x 25 is covered by a roof for our screened room. We would like to seal the concrete on the outside with a hydrophobic sealer to reduce slippage as it is a dock and is often wet. We also have a very small low spot 1 x 2 that collects a puddle and we would like to try an eliminate or reduce the puddling. Inside the screened room we would like to stain or paint the concrete floor and would need a sealer that can accept a water based top coat (we understand using a hydrophobic sealer inside may not work if applied first but what about after the stain? what about recoats of the paint/stain? Or just avoid the hydrophobic sealer inside altogether

    1. What State do you live in? Ontario

    2. Interior or Exterior concrete surface? Exterior/covered exterior

    3. Vertical or Horizontal application? Horizontal

    4. Change or enhance appearance (gloss or wet look) or no change of appearance? No change preferred, darkening ok

    5. Type of surface examples: concrete slab

    • Concrete Sealer Help says:

      You cannot stain or paint on top of a sealer not can you apply a sealer on top of a stain or paint. Does not work. In addition, no sealer is 100% hydrophobic.

      • Ryanoc75 says:

        I had done a bit of googling and found some hydrophobic sealers that claim to last 15+ years but they all seemed to be from overseas, primarily India for what that's worth. Nanoseal technology is what they claim, and it was the Defy product and Rustoleum's "Never Wet" that made my want to ask an expert. From what I could see browsing the net is that we are on the cusp of having these types of coatings and sealers but we aren't quite there yet. In your opinion what is the closest product to achieve this as I am confused by repellers vs proofers
        One of your top recommended sealers, Sila tek 3500 which is a concrete densifier and sealer according to the product description. It says on you can stain, paint, or topcoat that product which is why I asked in the first place.

        That said, I would still like to know what you would recommend for a durable, long lasting, slip resistant when wet, non yellowing sealer that we should apply to the dock. I have read about Concrete Densifiers, Concrete Water Repellants and Concrete Waterproofers and I'm unsure what is the best choice for our situation I would prefer not to have to reseal yearly if possible
        Inside I'm not as concerned as we have looked at stains and paints that have sealing characteristics.

        Thanks in advance for your time.

        • Concrete Sealer Help says:

          Sorry but we do not have not reviewed a product called Sila Tek 3500. Densifiers have been around for 20+ years. They are a silicon type product that reacts with alkali in the concrete creating an internal barrier/density. They strengthen concrete but really do not create a hydrophobic barrier 100%. Since they do not seal the surface in any way, you can paint over them. We do not use them as we honestly do not think they have much value. Kind of a gimmick in our opinion. A good siloxane/silane water repellent will last 5-7 years. Masonry Saver Heavy Duty or Super Seal M Water Repellent.

Then entire 18×45' driveway contains 2000' of Pex tubing wire-tied to 6x6WWF over a 2" thick Rigid-foam that was applied over a tamped gravel base. We used the melt-system to help cure the concrete, and did not turn up the temperature above 100F until after 30 days of pour. We have cracking from settling and want to seal them from water damage this winter.

    The cement is all that is left after a house fire. Sealant is to prevent smoke residue if any (after power washing) from infiltrating the house, or coming through paint or carpet.

    • Concrete Sealer Help says:

      Sorry about the fire :(

      Not sure if a sealer will or will not work for this. Try Masonry Saver Heavy Duty Water Repellent but call the manufacturer first to make sure.
