Finding a concrete sealer can be daunting with all the options out there. We put in the research time so you don’t have to! This know-how video will run through your options and outline the use cases for each type of product. This is a helpful video in and of itself, but it is also the 2nd of three videos on sealing concrete:
Part 1 - Cleaning Concrete ( • How to Clean Concrete ... )
Part 2 - Choosing a Concrete Sealer
Part 3 - Sealing Your Concrete ( • Applying Concrete Seal... )
Bonus - Sealing New Concrete ( • Sealing New Concrete |... )
In this video we’ll cover four primary types of sealers:
1. Penetrating sealers
2. Acrylic sealers
3. Polyurethanes
4. Epoxies
We spend the bulk of the time covering the maze of penetrating sealers. Primarily due to these being the best choice for residential, outdoor concrete where you don’t want the appearance or surface of the concrete altered. They are super easy to apply, will prolong the life of you concrete, and make annual cleaning a whole lot easier!

Polyaspartic sealers are not covered in this video. Mainly, due to these not being a very DIY friendly product. Application can be quite tricky.
I have a poured concrete pad 8 x 12 on which I will place a pre-built storage shed, however I wanted to seal the pad first. As you note, there were so many products and product types out there it "made my head spin". I spent hours trying to figure out which product to use, and became increasingly more confused.
It was clear, comprehensive, concise. Professionally delivered. Thank-you so much for this informative video. It is one of the best informational/instructional videos I have ever watched on RUclips.
Wow. Thanks so much! Excellent video. Old house, and sealing the basement, garage floor, and new concrete walk outside. You saved me so much time and frustration....not just for myself, but for whoever lives in the home after I'm gone. Thanks!!
Excellent informational video for sealer products on RUclips. Way to go man finally someone who can be straight up with facts so people DIY'ers can make a decision on what they want for their project. Thanks a bunch.
Happy to help!
Not boring at all! Exactly what I've been looking for. Thanks
Super helpful and informative. Thanks for the upload, much appreciated!
I have a step concrete on patio, driveway ans some steps. What sealer I cans use to be sure is not slippery in winter. Thank you for the video .
👍🏻👍🏻Very helpful and thorough. You didn't waste a second in these videos. Thanks!
Great breakdown!! Thanks! Will view many vids, but this is a great entry to 'what do I want?' Only thing I'd ask for is more in-depth on new/2-5 year/5+ year concrete. (since from all my research concrete never stops curing)
Lol. 5:40
Very good, thanks for sharing. I had to go out and look at what I'm using on a masonry wall. It's water based acrylic sealer from the local hardware store. I've used it before...seems to be good. When I think of sealer I think of that xylene based toxic chemical smelling stuff that everyone used when I was a kid. I don't want to smell that nasty stuff anymore.
This video series are really helpful. Thanks a lot.
Excellent information. Thank you. Strange to see thumb down !!
What would you recommend in a basement floor that’s is sweeting?
Liked the van Halen reference
Can you recommend a water based Siliconate for northern freeze and thaw sidewalk please ( 5 years old , cracking, never sealed) and a sealer for a long slippery ramp during freezing temps. Fell and got busted up pretty bad. ( ramp 1 year old, never sealed). Please help. Thank you!
Great video, great breakdown of products. Thank you for sharing.
Can you make review of cilicone sealer you have used. I want to know how long they last in real life.
Thanks! Exactly the info I needed.
I'm getting ready to reno the basement. I'm researching the best sealer. Penetrating seems the best, idc about the look, as I'm putting an underlayment n vinyl plank floor on top.
If you are putting underlayment and then vinyl plank, what are you hoping to accomplish with the sealer?
This video is so helpful. Thank you! I have vinyl tiles in my restaurant that need replacement. There is a beautiful concrete floor underneath. I am planning to stencil it with chalk paint and put a clear coat. Not sure what coating I should use that will last atleast a few years. Epoxy looks good but it will make the floor slippery with frequent water spills and all.
Hey Cindy and Mark! I hear you! We need the same thing in the US. We just don’t always do it. We live in Virginia by the Atlantic Ocean and it’s so beautiful here but still there are opportunist who will try your car or house!
I love that style of house. It’s just like in Brazil and the Middle East. The Arabs designed the idea of a wall around their houses to protect their women and children. Then, they spread that style to Spain. Can I find that style in most cities in Mexico? I want a small pool and open patio inside as well.
We have brushed concrete with an exposed aggregate ribbon surrounding. What type of sealer can be used on both surfaces without a slippery dangerous outcome. Thank you!
Very helpful. My problem is a condo on the first floor in Florida that has a mold problem. The best theory I have received from "experts" is that the concrete slab did not have a vapor barrier below the slab, so my moisture readings are good (about 5% RH) unless it rains, then the floor goes up to 99%RH. So, when it is 68 degrees out and a fairly dry November day, the interior humidity is still about 62% unless the air conditioning is set down to 70 degrees or so. So, they say to seal the floor before I put down vinyl plank flooring. One expert said use Drylock Floor, which is the penetrating type. The other expert said use Mapei Pleniseal PMB, which is a polyurethane compound. What brand would you use, or if you do not want to endorse a specific brand, what type would you use? I suspect you are going to say use a Silicate or a Silicanate if I followed your argument. Since I want to avoid upward water intrusion--sealing the floor with a penetrating sealer would make sense I suspect? Please help.
Hey I have this exact issue, did you ever find a solution?
Excellent breakdown! Ty!
I am looking for a sealer to keep oil/gas/diesel out of the concrete. What would you recommend?
Hello Jeff,
Is the concrete indoor or outdoor? Reactive sealers are great for blocking moisture and preventing freeze/thaw and salt damage, but don't offer the same stain resistances that coatings can provide. On indoor applications epoxy and polyurethane or polyaspartic systems can be used for long lasting resistances. On outdoor applications, breathable acrylic coatings are more popular, but must be re-applied more often.
@@VSEALVideos Inside a pole barn in WNY, I am not looking for a thousands of dollar epoxy job. But have looked at on-line epoxy sales as the local PPG dealer will not sell epoxy to homeowners. Eventually there will be a 12,000lb lift on it & may see steel dozer tracks on it.
Very helpful video. Thank you!
thanks!! what sealer do you recommend for a large exposed aggregate driveway. We also have the issue with salted roads in the winter.
Water based siliconates just be sure to clean the surface very well
I wish I knew what to use on the back concrete deck. It’s like stamped concrete and I want to pressure wash then put a coat of color. It’s on the south side and gets very hot.
Which is the best sealor for plished concrete surface.Note-Lithium based sealor mentioned here is actually a densifier which actually densifies the concrete.Further polishing is done on that densified concrete and sealor is applied at the last stage.So which sealor will be suitable for that last top application over polished concrete?
Good job, i know a lot more than before Thanks!
Great info. what would you use if you wanted a polished concrete floor for a home, especially in the bathroom?
Enjoyed the video. Keep up the hard work. Be blessed
I enjoyed the video! You gave me the exact information I needed to choose the sealer that I want to use in my basement. However, you did not mention any particular brands, nor did you mention a store where it can be purchased. I have been to three different Lowe's stores, Home Depot, Ace Hardware and Harbor Freight. When I told them that I wanted a sodium or lithium silicate concrete sealer, they looked at me like I had a tree sprouting out of my forehead.
What brand do I get? Where is it sold?
Great video. Learned something!
This was so helpful, thank you kindly.
Happy to help!
This was perfect 👌 Thank you! 👍
How would putting chips in the epoxy help with traction? There's a top coat or two that goes on top of the epoxy to give it a nicer shiny appearance.
Thanks for such a clear and well-thought out video explanation. Can I ask for advice on my situation / application?
I'd like to seal a large driveway, of which 520 sqm / 5564 square feet is "new" (32mpa poured 4 months ago) and 80 sqm / 856 square feet is ~30 years old (assume standard 20mpa concrete), comprised of slab under a drive-through carport (consistent / uniform grey surface) and 2 exposed sections with slightly different aggregates - rain and exposure has weathered them so the aggregate is prominent on the surface but they are in good condition and very usable hence not removed when new driveway was constructed. I'd like to seal all the driveway, and would prefer a sealant that can make the driveway look more uniform, preferably a dark charcoal grey. We get a fair bit of leaf staining and some animal droppings staining. My priorities are:
1) Achieve a uniform colour and look as much as possible so it's hard to determine old and new driveway sections.
2) Protect the driveway from staining from leaves / animal droppings.
3) Reduce water penetration so above staining remains surface only for easy pressure-cleaning or just waiting for next rainfall.
4) Be long-lasting so I'm not re-doing it in 5 years.
5) Protect concrete (we don't get frosts or snow) from erosion if possible, although I'll likely sell before I see the new driveway weather like the 30+ year old sections so this is less of a concern.
6) Maintain or increase traction from current unsealed state - kids love running on it and riding bikes / scooters so don't want to end up with a slippery surface.
Thanks for any advice you can provide - from this video I am wondering if the Siliconates have dyes / colour additives that can be used, with different amounts for the different sections, to end up with a fairly uniform appearance, as it would achieve the other points well.
FWIW I'm Down Under and our driveways are 100mm / 4" thick with 82 reo (8mm diameter steel in 200mm x 200mm grid mesh = 5/16" x 8" x 8" mesh in 8' x 20' sheets tied) usually 20mpa but I got a very cheap upgrade to 32mpa for the new section so took advantage.
Quality review
Great videos, can I use concrete sealer and than go over that with a polyurethane? I have an outside deck that’s concrete underneath. It is my garage and the concrete is always weeping into my garage.
@toolboxdiy , what sealer is recommended for exposed aggregated concrete? Also, is there a tinting penetrating sealer you would recommended to add/change color?
Thanks.
Any suggestions on Concrete piers which are cracked due to efflorescence
Are there stains that work well with penetrating sealers?
Can you paint the concrete once it has been treated with one of the penetrating sealers?
How long can silicate penetrating sealer resisist water penetration in a concave concrete surface? (Horizontal/outdoor)
I have the same problem and no answer.
Hello. I am going to seal the concrete subfloor inside my home to reduce inside humidity. Which type of sealer would be best for that? I like the idea of reducing radon as well, but that's not my primary function. I don't care how it looks, as it will be covered by vinyl flooring.
Good video, far to many amateurs doing videos on stuff, filling the universe with junk. I'm doing a small project and I have been told from a friend that Weldbond glue mixed with water is good for sealing concrete, you know or is it true about this inexpensive alternative to all the other stuff.
Hi.. can the penetrating sealers be applied on brick also?
Can a penetrating sealer be used over the top of a high shine acrylic sealer? We are looking for options to fix a bad install job of a specchem acrylic sealer that was recently installed.
How long do the siliconate sealers last? How frequently would you need to reapply
Thanks for the video series. I had a failed epoxy floor that I have ground off with a concrete grinder. I now want to protect the floor from oil stains and salt but Im unsure If I should use a a siliconate or an acrylic sealer. I wouldn't mind applying an acrylic every couple years but Im unsure if I would have to strip it every time . If I use siliconate sealer I'm afraid of oil stains especially since I knocked off some of the cream with a grinder and perform my own oil changes in the garage. Any sugestions?
What did you end up using?
Acrylic sealers, Like Kemiko Stone Tone 2, do not have to be stripped. You should clean the floor with a neutral cleaner and a stiff broom brush. Rinse, re-rinse, let dry. Then spray seal with a pump sprayer. They are forgiving, dry fast, breathe-able (not a moisture barrier), and when they wear they kind of "powder-off". You simple re-seal over the cleaned concrete. I apply them every 2 years on indoor concrete with average wear and every year ( litely, sprayed) if outdoor. Indoor, I use I use Kemiko Easy Shine Mop On Wax to protect the sealer so you never have to re-seal. No need to buff the wax either. It's a great product. See concretetransformed.com
Can the penetrating sealant work if the concrete was painted...25 years ago?
Seeking a recommendation on a sealer for old concrete in a home. I inherited a home with a cat urine problem on the concrete floor. I’ve tried everything to clean the urine. At this point need to seal the concrete to keep the smell form coming thru the luxury vinyl plank floor esp when the concrete pores open when it rains outside. What type of sealer is recommended?
Experts - for radon mitigation install , contractor made a hole in concrete wall and filled the gap around the pipe both inside and outside of concrete wall with Alex Plus Latex Caulk Plus Silicone . Is this good or should I get sealing around pipe with a better product?
You made a comment about newer methods of finishing concrete, like using a big power ride-on float. I just had a garage floor poured and they used one of these. Do I even need to seal it all? If so, which type do you recommend? Thanks!
So what type of sealer would Thompson’s Water Seal be? What would be best for Block
Walls, densifier?
Thanks for this Vid. One question though. Can say, Acrylic or Polyurethane be put ontop of A Penetrating Sealer? Since they're not penetrating and just sits on top.
Does this information apply to cool decking around a swimming pool? Should I seal it just like any concrete or would that mess up the cooling surface? Thanks!
Pls how can you share with me the chemicals use in producing the acrylic sealer? I am doing a project on it.
What are the Guarantee/Service Life Expectancy Of Siliconates?? .... And/Or Each other te Different Penetrating Sealers.. ??
Here in Northern California the weather in the summer gets to the 90s or triple digits. I want to protect my concrete driveway, what is a good sealer that will protect from high heat in the day and cold morning?
Thank you. Very good
Very helpful Video series, what kind sealer do you recommend for outdoor brick staircase, thank you.
Hello... what is the best sealer for smooth concrete with water based dyes on top?
I thank you for your very informative video. I live Florida and Moss keep growing on the concrete outside my front door even after I power wash it 3 months before. There is no standing water after rainfall. The salesman at Home Depot says its moisture from in the concrete that causes the Moss to grow. Should I use a penetrating sealer to slow the growth or stop the growth of Moss
The penetrating sealer will definitely help. If the slab drains well (meaning it has a slight pitch so that water doesn't just sit on it), then it will probably solve the moss. If water still sits on the slab, moss or algae may still grow but it won't be as bad and it will come off much easier.
@@ToolboxDIY Thank you thank you very much. Water do not sit after a downpour. I like the way the product work
Why do you prefer siliconate vs Silane-Siloxane
potassium silicate can also be used
Thank you so much! Question -
I’ve just built a house with fully exposed concrete in and out. Lovely and smooth concrete just near the sea. Some walls have been poured 3 months ago while others 4 weeks ago. What sealer should I use that will protect and harden but not alter the look in any way (don’t want the wet look!). Many thanks!
What would you recommend for sealing over probable asbestos black mastic on concrete slab? Home was built pre 1970.
Great information. Thank you for doing this. We have a new home with a standard patio slab (poured and brushed). We added a 4’ wide extension and walkway about 3 months ago. The colors are slightly different. What would you recommend for possibly a stain to even things out and then seal. Durability is our most important concern. I have not seen any tinted siliconate water-based sealers. Thank you so much. We appreciate your help.
hi could you help and if possible advise . i have used different tips of floor sealants on the concrete . it is around a pool and continues into a patio , after two years starts turning white spots and the color of the color concrete starts fading and i have to stripe and re seal its becoming a pain .please help.
Needs advice on which concrete sealer is best for our concrete patio please..
Great info! Thx
I have an older home and the patio has has some paint on it and then 10 years of artificial turf. I'm now changing the turf and I want to seal the concrete, before getting new turf put on. What can I put on old concrete, that has had cracks treated with concrete silicon, still has paint on it and it has little holes in it. Also it has some adhesive that I can't get off. I can't possibly get all this off before the turf installer comes. What can I cover or seal this with???
*Which is the best one for concrete driveways on residential properties?*
Great explanation! I'm going to do my pool deck that is about 10 years old but want to stain it also. I want to use a penetrating stain like you said but the question is do I still need to seal it after staining? I've read conflicting articles on this. I would think you would but then agin that is why I'm asking for your opinion. Again great job explaining!!
Excellent content
Which penetrating sealer brand would you recommend for a two car garage which is two years old.
Good afternoon. Thanks for a great video. I'm looking to do DIY concrete countertops. Would you recommend a Siliconate sealer for this application? I used to have granite and used the Granite Shield company, but I'm looking for more of a DIY solution and something a bit less expensive. Thanks for your time in replying.
also interested in this application

Hi thank you for posting, very helpful! I have an outdoor kitchen / BBQ with a colored concrete countertop. Do you have any suggestions or recommendations on the type of sealer to use for this particular setting? Thanks again!
dou have any suggestions for driveway sealers or paints type that can be used ?
I primed and then painted the basement recently. Then I used Thompsons Watersealer. It has been sticky without totally drying though. What should I do? I'd like to preserve the paint if possible and definitely remove the stickiness. If I use epoxy over the sticky floor do you think it will adhere and remove the stickiness.
I lost my wood floors due to flooding from Hurricane Harvey and will be replacing with a fresh pour of concrete. My plan is to use a siliconate sealer per your recommendation (going with natural concrete, no stain). Could you tell me if getting the sealer on the exposed wood framing (where sheetrock was removed) is ok and won't require masking? It would certainly make the process go faster if I can skip masking. Really appreciate your videos and these concrete sealer videos are very helpful to me in my recovery process.
@Charles W - Aw man, I'm sorry to hear this. I sure hope the damage was minimal and, more importantly, that you and your family (and pet!) stayed safe through that ordeal. It's not as much fun to be forced into a DIY project as it is to choose one. Hats off to you for tackling your recovery process.
As for getting the siliconate sealer on wood, it won't do any damage to the wood, but it could alter the appearance. Since these are framing members, I assume you'll get new sheetrock to cover them back up. If, for some reason, you plan on keeping the wood exposed, you might want to grab a 2x4 scrap and spray it with the sealer to see how it looks after it dries.
Good luck and don't hesitate to ask any further questions.
QUESTION: If I put a high solvent high gloss concrete sealer in my basement... are the high VOC (carcinogen and other toxic materials) fumes STILL considered to be dangerous AFTER the floor dries? Or is it ONLY dangerous while applying and not dry yet?
And if the answer is "Yes" these type of VOC sealers are still dangerous for indoor purposes even AFTER the floor dries... do you know of any "High-Gloss" water-based sealers that you would recommend for indoors/basements? Thanks again!
Hi can you recommend a sealer that is non toxic non flammable. I'm making vessels for candles with rapid all cement and need a sealer that won't release toxic chemicals while candle is burning. Thanks
I plan on using some peal and stick on tile. Is it necessary to seal under this type of flooring?
Hi , which sealer would you recommend for sealing a concrete water canal floor? With lot if sun exposure in tropical area. no ice .
I want to coat my concrete septic tank so I will never have to replace it.
Opinions?
Which sealers are sage to plants for concrete pottery
Can I use any of these on acid stained concrete? I’m looking for a matte sealer or very low sheen. This homeowner likes low sheen . And the slab is flawed . So the low sheen would look best . I just want to bring out the colors in the stain and not have the sheen . It’s a rental house . So it’ll have a lot of foot traffic. Thank you for the video 😊
What is best to use on molded concrete? I have molded concrete around the foundation of my home and it's starting to crumble. Can I paint over the sealer with a waterproof paint?
Is there a wet look sealant?
Or should I just use cooking oil ( ooops,I mean mineral oil)
We have a new concrete patio and are wanting to get it sealed. It dusts really bad so we track the fine white dust in the house. We also do a lot of water activities and don’t want something that will make the concrete any more slippery than it already is. What option should we go with?
Winter are 2-3 months below freezing here and we use salt. What would you recommend for aggregate driveway and concrete walk ways around the house? Much appreciated.
Great video. What sealer would you recommend for a highrise condo unit with an interior polished concrete floor ?
Is sealed concrete more slippery if you use the sealer you recommend for most homeowners?
I have an out door, concrete patio. Hanging over the patio is a large pine tree. Sap drops all the time and because it's not sealed in any way, I can't get the sap out of the nooks and grannies. Am I better off with a polyurethane or epoxy sealer. I live in the south west and my days in the summer are over 100 every day, if that makes a difference.
I'd go with a polyurethane over the epoxy. The epoxy will yellow. A penetrating sealer will keep the sap from staining the concrete but it will require more work to clean it off than if you used a poly. Acrylic is also an option. It's not quite as thick as poly so it won't last as long, but I think you'll be happy with it's performance and it's easier to apply.
Any thoughts in what would be a good sealer for surcreate. We applied it indoors as a coating over a concrete floor.
Thank you!
