20 Best Liquid Cement Crack Filler (2023 Updated)

I thought it worked great once you understand how to use it. It cures ultra fast and goes from a very runny liquid to harder than concrete in less than a minute. You literally have seconds to use it so just mix up small batches in a plastic containers.

Pour it into the cracks and sprinkle sand on it real quick before it starts curing.

Ink cartage is easy to install in the printer and produces high quality and streak free print jobs.

Works fine. Good product. Easy to install. Salesman at Office Depot very helpful.

The instructions say to use a torch I used a small one with adjustable flame and a large one with a three inch diffuser both discolored or burnt the gray sealer. This was applied to one month old concrete that was cleaned two days prior and allowed to dry.

If you’re wanting to fill a gap and don’t care about the looks it will work. Before buying I looked at many reviews and it seemed like a great product but the amount of heat needed seemed to vary and it may be the plastic it’s wrapped in.

I don’t know but I do know I ruined a nice walkway and patio I made for my mother in law.

Works great so far. Using it on concrete warehouse floor. Stays slightly pliable in cool temps, so I am hopeful it won’t crack and pop out like epoxy. My heat gun works with it just fine, although I suspect a torch would be faster.

Very good product to fix small cracks in basement, I can see it flow into those cracks before it is harden. I prefer to deeply fill into tiny cracks. I added 30 ml water with though mixing. It is amazing.

Now I could see all tiny cracks filled deeply.

In May 2020 applied this product to fill hairline cracks on concrete water fountain and bird baths. Now it is end of August and seems to have done the trick in filling the cracks and stopping the leaks.

Since it is pourable, is easy to apply and hope it stands for few years with the right care of winterization by removing the water and coving the basins.

Used on basement floor cracks, the product doesn’t settle into cracks and instead an simply left a bead proud of the surface. Rotary sanding solves the bead. but revealed that penetration wasn’t complete.

I am sorry to have read that people here have been having issues with the flowability of this product. Personally, I find this product flows very well and really gets into cracks and whatnot. So maybe some here are getting old product that is already on the dry side? The dry time depends on how much of a gap one needs to fill but even with a more deeper application I find that it only takes a few hours to dry.

Its dries as a rubbery concrete. The colour always tends to be a brighter grey at first but give it a few months and it will gradually darken due to the elements. You will most likely have to reapply every 5 years or so, at least if you live in an area that has winters.

But once again, if you get this product in proper form it is very easy to apply, anyway. Definitely easier than constantly having to remove the weeds that emerge within the cracks or gaps between my concrete slabs.

I poured this into several concrete cracks. It was messy but fingers crossed it works. Dries pretty fast so need to do shorter lengths if you want to clean up any excess. Instructions are so buried in the warnings make it hard to read.

Good product. I’ve used it before. Maxwarehouse had best price and fastest delivery date for standard shipping. Product arrived a day before the estimated date. Very happy with Maxwarehouse.

It does a good job in filling in cracks in concrete. The color match is a little off, but it looks better than having cracks.

Needed for smaller cracks in my cement in front of garage. Easy to apply. Did notice fine crack in this Filler(parallel to the cement crack) the day after I filled the crack in cement.

First purchased last summer to repair some cracks in my stone retainer wall. It was a lot easier and less time consuming than mixing mortar and trying to get into small cracks. You don’t want to over fill cracks to much and with a latex glove just run your index finger across to smooth out.

In this instance less is more. Here it is a year later and it’s still holding strong. This past winter I repaired a few vertical cracks in my stone wall basement using a little more and smoothing it out a quarter inch each side of the crack.

I’m now in the process of painting the basement walls with Drylok Water Proofer which should help prevent any further cracks by keeping moisture and condensation out. Last year the Liquid Nails Concrete Mortar Repair was a darker gray which blended in with masonry stone, but now it is a very light gray and very noticeable, but you can paint over once it has completely dried.

Shocked and surprised no one has wrote a review this product is the absolute best. I’m a female in my late 50’s and and expect any product to do what it says it will, this absolutely does.

I own a house with some brick components–that is 121 years old. Mortar has needed replacing in a number of areas. This stuff works great. It goes in easy–and if you wait a day or two you can use your fingers to smooth out any places where you insertion with a caulking gun is not quite perfect without it sticking to your finger.

It needs to dry a bit before you can work it with the hand. But–once you get the hang of it–you will find it makes a wonderful seal–it matches most mortar–and it is waterproof. It is easy to blend it in with the existing mortar and matches perfectly.

Highly recommended.

Had to used the glue for water proof adhesive , putting up shower panels, the directions are to be followed to a T if you want excellent results. There are many adhesives on the market and I have used liquid nail extensively.

Liquid nails will cost a little more, but will stay put. The only real factor to keep in mind is the temperature, other than that it works well and comes out smooth. I used rubbing alcohol to make sure my surface was clean and free of any oil or dirt.

I also used the alcohol to removed any seepage in the cracks.

After 15 years the sealant cracked along foundation. The driveway settled 1″ no chalking would have worked Remove old chalking and replaced it. The saw cut joints are showing some pin hole cracking. After 15 years it is expected.

Make sure you buy fresh batches and use it all up. I read the reviews and if you buy old stock it is thicker and impossible to use. Return It.

Back blew out immediately after squeezing the tube. Seems like it could be a decent product otherwise. It doesn’t seep into cracks well but seems good for superficial repairs. It can be useful under certain situations.

very well made concrete in a squeeze tube easy to seal all minor cracks n all minor holes great ust for all around minor repairs

Easy directions. Great filler for small cracks.

Arrived within three days of ordering. Was very well packaged in a double box. I am looking forward to using the Sealant on the cracks in my concrete concrete driveway to prevent more damage next winter.

Ever since I’ve started using this concrete sealant, I’ve been truly amazed. This concrete sealant is some of the smoothest and easiest to use sealant I’ve ever used. I especially like how easily it comes out of the tube.

Another feature that contributes to this product’s ease-of-use it its ability to self-level. It simply smooths into whatever cracks your concrete may have. I did not have to use any tools to apply this product.

Another great feature about this sealant worth pointing out is its quick dry time (although it is not actually supposed to completely cure for about a week). I applied this on an area I needed to seal and by the next day, the area I had applied the product to was completely dry to the touch.

I also really like the fact that this sealant is completely waterproof. I have not needed to reapply this sealant since I put it on my front porch (I had cracked the concrete porch area outside my apartment and did not want to have to pay for damages).

Thankfully, this product did the trick! I can’t event tell that there was a crack in the cement! The only disadvantage of this product is that it flows out of the tube very quickly. You have to be very careful when you are applying this product because you could easily squeeze too much of the sealant out of the tube.

However, overall, I’m very pleased with this sealant and would highly recommend it to anyone that is looking for an easy way to fill cracks without there being any signs of repair.

I used this product on several large cracks that spanned the entirety of a 12′ slab. The slab was laid about 4 years ago and cracked for an unknown reason. I’m not a mason, nor am I a contractor; and still achieved the results I wanted.

I live in northern Pennsylvania, so our “freeze-thaw cycle” is tough on concrete. I wanted to get the cracks filled before water got in there, froze, and split apart further. I followed the directions to a “t” and had no issues.

I did wear rubber gloves and cleaned up with mineral spirits. The caulk dried quickly and stuck to everything easily. It’s a really tacky substance, so I have no doubt that I got a good bond with the concrete.

The color match was close to what the tube indicated, and looks fine on the slab. Unless you plan on epoxy painting the entire slab after you use this product, you’ll see where it was filled. No product is going to match your concrete exactly, nor do they advertise that.

I was surprised how well it leveled itself out, which is fantastic. I didn’t have to trowel or level it myself This product dries HARD. Which is what I was hoping for! It’s been two weeks since I made my repair, and it is still holding up great, and looking great.

So far we have had rain, snow, and temps that swung between 12 to 65 degrees, all with zero issues. I have no doubt that this caulking will last for years. As soon as spring gets here in 5 months, I have plenty other spots that I will be using this product!.

We had several places in our automotive shop where the concrete had broken out around floor fixtures or had opened large cracks. Each of the components comes in a paste like consistency which becomes very fluid after mixing the two components.

We were able to fill cavities and deep cracks where it seeped in and filled the cavities and cracks. After it set up, which took longer than advertised, we were able to sand off the excess to level the patch before painting the floor.

We had previously patched this floor with other concrete patches only to have the patch fail in time. This is an awesome product.

Great product for filling cracks on old concrete. price is on high side. Needs to have little bogger size. I live in mountains. Bog box is 65 miles away. For me get on computer and wait for 2 days. For me it’s lot cheaper.

Product – A+, Service – A+.

ZORO is middleman ( distribution agent). I used this product before. So nothing to talk about it. As far as ZORO is concerned, logistic was A+. It supposed to take a week but I got it in 3 days.

I purchased a different brand at F&F at similar price point that touted flexibility. It was rock hard in a few hours on warm day. This product definitely retains flexibly much better. It’s only been in place maybe 4-5 weeks.

So far, it’s stable and not coming out.

This product is easy to use. Be sure to stand the bottle upside down overnight before you use it. It is quite heavy to shake it if you don’t. It works good on smaller cracks, so fix it before the crack gets too big.

Had a hole in the TV room floor. Used this product, easy to mix and apply, it dried and the hole is gone. Don’t know about it’s longevity but it looks like it will last! Only problem is color match and texture to the epoxy floor color.

Foundation crack filled with minimal fuss. The stickiness made it interesting to apply, but also lends confidence that it really will adhere and seal the crack.

This is a superior product to use on the hairline cracks in my driveway.

When I tried to discharge the two section of the epoxy and cement it was extremely difficult, even with a ‘professional’ mastic gun. I ended up unscrewing the supplied mixing nozzle from the main tube and ONLY then could I discharge the two components from the tube.

This I did into a glass bowl and mixed the product by hand and applied it to the cracks using a small trowel. This I did with TWO tubes!! However, the end result was satisfactory.

This stuff really works. I had to redo lock block steps after the builders tried 3 times and failed miserably. This held the steps well. Only issue, don’t use the mixing tube unless you have to. Pump the two products out onto a piece of hardboard and mix by hand with a pallet knife or similar.

Easy peasy.

its good stuff and works well, note that the tube is only about half full so check the ML you Require rather judging it by the contents of the tube
