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.

    • Concrete Sealer Help says:

      Garrett, sealer will not fill cracks. You can seal the concrete to minimize the concrete from getting more cracks. Try SuperSeal-25.

    We have a indoor horseshoe pitching facility with a concrete floor 40′ x 46′
    our floor is 20 years old it has a smooth finish
    we have a lot of dust from the CLAY
    The floor is cleaned each week by mopping with water and cleaning liquids
    The floor was sealed when it was poured 20 years ago.
    would it be a good idea to seal it now
    we have painted lines (white) in the pitching platforms where we pitch horseshoes from and would not want to discolor them what type of sealer could we use?

    • Concrete Sealer Help says:

      Ron, best to seal with a deep penetrating sealer that does not change the appearance. It cannot be applied over painted lines though. No sealer that we know of can soak into paint well but we could be wrong. Might be a good idea to call the manufacturers of the sealers to ask first. We would try Masonry Saver Heavy Duty Water Repellent.

    I'm not sure i have any economical options
    i am in northern california – lots of sun and heat, rarely freezes
    exterior
    horizontal
    id rather not change it to a wet look since it leads down to the pool area and i don't want to have to change everything
    we have an exposed agg concrete patio about 16×3 and we use is as an outdoor living area almost year round
    my only problem is that it is so rough on the feet! it's too bumpy and is very uncomfortable going barefoot on – but in the summer it's so hot we know better anyways – but it's so dry i swear it sucks the oils out of our feet even if we go barefoot at night – is there anything that will make it overall gentler on the feet? is there a sealant that can fill in some of the roughness like nail polish base does for fingernails? and im worried about if there is such a thing that it will make the patio slippery,awe are getting the next generation in our family now so i have to keep that in mind for the babies!
    thank you sooooooo much for any knowledgeable information you can give me on this!!!

  5. jackie says:

    i just posted and waiting for review – i guess i should have added that our exposed agg patio is a little too exposed for what we think a patio should be so if the product you recommend would actually pool in the deeper little pitted areas, id need to know if we need to worry about how thick the layer is during application so we wouldn't have any issues with buildup discoloring or flaking – i hope you know what i'm trying to ask :?
    thanks

    • Concrete Sealer Help says:

      Jackie, the only way to \”smooth\” the surface is to add a sealer that will film on top of the surface. This will darken the color and leave a sheen as well. I would contact Saverystems. They manufacturer a product called Masonry Saver Decorative Concrete Sealer. This may work for you.

  6. Greg says:

    1. What State do you live in? Texas

    2. Interior or Exterior concrete surface? Interior, basement

    3. Vertical or Horizontal application? Vertical basement walls

    4. Change or enhance appearance (gloss or wet look) or no change of appearance? No change in appearance is needed

    5. Type of surface examples: Driveway, Paver Patio, Brick Wall, etc Paver Concrete basement wall

    • Concrete Sealer Help says:

      R2oG, nothing will probably stop the dripping 100% as you most likely have a structural issue. You could minimize it though with a product like Defy Heavy Duty Water Repellent.

  11. Marie says:

    Help! Completely confused over what sealer I should use on my new front porch. I like the idea that a sealer would darken the color, but not sure about the shine factor. It's a 1920's bungalow with roof covering the entire porch..although it is west facing.

    1. What State do you live in? California, Los Angeles

    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? satin maybe?

    5. Type of surface examples: Porch- west facing covered porch on old craftsman home

    • Concrete Sealer Help says:

      Marie, is this plain poured concrete or some kind of decorative concrete surface? Wet look sealers do not work very well on plain concrete.

      • marie says:

        sorry, realized i didn't specify. it is plain poured concrete.

        • Concrete Sealer Help says:

          Marie, for plain concrete it is best to use a deep penetrating sealer that will not change the appearance but will protect against stains and weather. Look at the Masonry Saver Heavy Duty Water Repellent or the SuperSeal-M.

          • marie says:

            thank you so much for your help. My number one concern is protecting the porch from stains so either of those should be perfect.

    • Concrete Sealer Help says:

      Alan, for a garage floor it is best to use a sealer that will not change the appearance or create a film on top. Use SuperSeal-M for a deep penetrating product. It reacts with the alkali in the concrete creating an internal barrier. Stains or spills will not penetrate deep and can be cleaned off.

  13. TpaGrl says:

    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? Would prefer a matte or satin finish to a high gloss finish.
    5. Type of surface examples: Driveway, Paver Patio, Brick Wall, etc Paver Driveway. Backyard paver patio and screened in lanai. The lanai is thin pavers over a 2 foot high concrete base. The patio is thick pavers at/slightly above ground level on a crushed concrete base. The area is heavily shaded by Oak trees and quite moist, but no standing water. There will be a 5' x 7' hot tub on the patio.

    • Concrete Sealer Help says:

      TpaGrl, if the ground is constantly wet then your pavers can retain water. This can create an issues when sealed as the moisture may not be able to escape, turning white in color under the coating. Best to use a breathable sealer that will minimize the chance of this happening. Try Defy Paver Sealer or the SuperSeal25 as possible options.

  14. Stephen Yuen says:

    1. What State do you live in? Houston, Texas

    2. Interior or Exterior concrete surface? Exterior

    3. Vertical or Horizontal application? Vertical

    4. Change or enhance appearance (gloss or wet look) or no change of appearance? no change

    5. Type of surface examples: Manufactured Stone Veneer wall at house entry. (Eldorado stone – Texas cream)

    The wall is done by a contractor with sub-grade waterproofing behind the stone. Only one layer of felt paper is used I need a permanent water proofing or seal into the wall to protect the wood sheathing behind it, while I like to keep the same or minimal change in wall appearance. Would you recommend a product, and that is available in Houston TX? Thank you.

    • Concrete Sealer Help says:

      Stephen Yuen, you could try a product like the Masonry Saver Brick Water Repellent.

      • Stephen Yuen says:

        The product name shows its for brick. Is it also good for manufactured stone?
        Is there product specifically for manufactured stone? Thank you.

        • Concrete Sealer Help says:

          Stephen, there is not a product designed just for manufactured stone. I am pretty confident this will work but best to ask the manufacturer to make certain.

    1. What State do you live in? Florida

    2. Interior or Exterior concrete surface? Interior

    3. Vertical or Horizontal application? Horizontal

    4. Change or enhance appearance (gloss or wet look) or no change of appearance? Enhance color of dark brown "chocolate" grout on tile floor. I put a water based acyrlic sealer on it, and was very disappointed. It goes on milky, and doesn't dry completely clear. When the grout is wet, it is a gorgeous brown. Thought I might be able to use remainder on concrete sidewalk. Appearance not really an issue on sidewalk. Why am I here? I just think that a lot of times things are packaged wayyyy to expensive for the use( like solvent grout sealers, $50 / quart ) because "you don't have a lot of grout", so they charge more. Yet grout is a portland cement product . So you find something for sealing something like a floor or driveway, and you get much more for your money. Worth a shot, so I thought I'd ask.

    5. Type of surface examples: Interior grout primarily, exterior sidewalk.

    • Concrete Sealer Help says:

      cs2870, I agree with you on the packaging but unfortunately I am not sure what would work well on interior grout. You could try an acrylic solvent based sealer but you would need to be very careful of not getting it on the tile and it will have a very strong odor.

  16. amy47501 says:

    Hi, Thanks for the offer to provide an opinion on the best sealer(s) for specific applications. I live in Arizona (the desert part, Phoenix area). The concrete is both interior (garage) and exterior (driveway, sidewalk and patio). The patio has a roof but the outside foot of concrete gets wet anyway, from wind-driven rain. All are horizontal applications. The appearance is matte, which I don't want to change. I don't know about any previous sealing, but it has to have been at least 15 years ago because I did not know it was necessary, and that is how long I've owned the house. (I have a bit of surface crumbling at the edges of the driveway now.) The type of surface is smooth, poured concrete with expansion joints.

    Salt is not a problem in my area, but UV rays and intense rains (in two seasons of the year) are.

    Thanks,
    Amy

    • Concrete Sealer Help says:

      Amy, I believe you want a sealer that will not alter the appearance but will protect. Look at SuperSeal-M or the Masonry Saver Heavy Duty.

  17. Barb says:

    We live in Minnesota and have Efforescence on our basement concrete brick interior wall. Would like something that once the efflorescence is dealt with will not change brick appearance. Will deal with contour of landscape in this area when and if Spring arrives. Thank you. Barb

  18. Tom says:

    I live in Pennsylvania, and want to seal my exterior brick porch and pathway. It has polymeric sand joints. I like the wet look, but not glossy. The primary goal is to stop rainwater from collecting under the small porch and then seeping into the basement wall, leaving efflorescence – a white powder and brownish crystals.

    2. Interior or Exterior concrete surface? Exterior

    3. Vertical or Horizontal application? Horizontal

    5. Type of surface examples: Colored concrete under pavilion but would get some sun in sections, blowing rain and have to deal with children and dogs prints

    • Concrete Sealer Help says:

      LeAnne, is this stained concrete at the surface or was the concrete pre-tinted throughout before install? Is the surface very porous?

  21. Mike says:

    I live in New Jersey and have a stamped concrete patio and stamped concrete around the pool area. I know it is at least 20 years old and do not know how long it has been since last being sealed. Color has faded and needs to be sealed. There is dried up cracked sealer in some areas. How do I get rid of the old sealer and what brand should I apply? I see super seal 30 is highly recommended on your site? Good choice? Thanks for all the great info….

    • Concrete Sealer Help says:

      Mike, yes the SuperSeal30 is a good sealer for stamped concrete. You most likely need a sealer stripper to remove the old coatings. Clemons Concrete Coatings makes a very good stripper for this.

    Floor recently ground to 1500 grit or better. Sealed with densifier but not a lot of sheen on some parts. Previously painted with epoxy but chipping made it look terrible. Not interested in a paint type product but possible a wax and sealer. Approx. 10000 sq ft.

    • Concrete Sealer Help says:

      Ron, try a acrylic based sealer first then a wax on top for periodic maintenance. SuperSeal product by Clemons Concrete Coatings is what we would use for this.

    • Concrete Sealer Help says:

      Gordon, might be best to remove since you said it has become spotty. Urethane sealers do not last any longer than a acrylic sealer when it comes to retaining the shine. We use the SuperSeal 30 for stamped concrete and while it dulls some, we do get a couple of years out of it.
