Product Overview

Fill concrete cracks and joints without using a pro grade melter with the 1/4 in. Small Gray Crack-Stix Permanent Concrete Joint and Crack Filler. Originally used for federally specified highway jobs, this filler is an easy permanent solution for keeping concrete smooth. Crack-Stix is applied with heat (a simple hand held torch) and bonds to the sidewalls of the crack. Unlike some fillers, Crack-Stix expands and contracts along with the weather to keep joints and cracks sealed. Designed for joints and cracks from 1/4 in. to 1/2 inch in Dia.
  • For concrete joints and cracks 1/4 in. - 1/2 in. (6.35 mm - 12.7 mm) in diameter
  • 225 ft. (68.5 m) of small-gray Crack-Stix
  • Hot applied, self-leveling gray, rope like filler bonds to sidewalls
  • Traffic ready in approximately 20 minutes
  • For deep cracks or joints, before you begin fill the crack using closed cell high heat backer rod, sand, or stone dust but leave enough room for product
  • Chlorine resistant - great for pool deck concrete joints
  • No volatile organic compounds
  • Prevent slip, trip and fall accidents
  • Will also work on faded blacktop (for those that do not want the contrast of a black crack filler)

Final results was not gray
Overall, I am very satisfied with the product and the ease of installation. I installed over 350 ft of the product. It is a little time consuming going through the preparation and heating process, but I believe it gives a very good seal. The only issue is it is not gray. It comes out of the container gray, when it is melted it is gray, but once it has cooled it is a cream color. This was not what I was expecting, and it is not as desirable as having it in gray. Do not buy the recommended tool. There are others available at less than half the price.

    I really like the product. I used 225 FT in two weekends as I have a large driveway. The hardest part was cleaning out the old stuff. I filled the gaps with sand to with in 1/4" then put the the stix down. I used a hand torch (Northern Tool) attache to a grill propane tank. The torch was plenty hot and melted the material easily. Torch made it easy to stand an walk along cracks. I did have to watch along my house / garage as the heat from the torch almost caught the siding on fire. I already ordered my 2nd bucket. I did like the smaller 1/4" as it generally filled most of my cracks. There were instances where I used 2 strands for bigger cracks. I thought this was easier than using the 1/2" and having too much. This definitely beats using caulk and bending over.

      I bought this product based upon favorable reviews by others. The reviews were very helpful and I knew what to expect in installing the product. It took a lot of time and effort but I am thinking it is a permanent solution to a problem I have had for years. The cracks in my aggregate driveway were large and I have attempted other solutions without success. The builder of my home poured slabs that are to large resulting in large cracks. As a result I used in excess of 700+ feet of this product. If it works, it is much cheaper alternative to replacing the driveway ( a potential $20,000+ renovation). The real key for me is how well this product lasts through the winter and I plan on providing feedback to the company if it does not work. The cracks I repaired were large and I followed the instructions to the letter. I like the results and currently recommend the product. I noticed with the first rain that it really repelled the water from my driveway. The product literature indicates you can reheat the product if the desired results are not what you want. I found out that this is accurate. While it does not come in sand color, I have noticed it is taking on some of the color of the existing aggregate driveway. If it stays sealed and keeps water from doing additional damage, I will be extremely happy. My rating is based on results. Keep in mind it is a lot of work to install. It has been installed less than 30 days.

      If it over burn it may damage your drive-way
      The idea was good but there are some issue that may cause more problems than fix it. I find out that plastic wrap did not melt with the bottom part, when you burn the top will melt but NOT the bottom because of the plastic wrap. The best way is to remove the plastic before you put it in the crack but there is more work than I thought, also forget the burner use the heat gun much better.

      Dear Customer , I apologize for your experience with this product, I did reach out to the MFG for more information on this issue and below is their response to you. The remedy to the problem experienced by this consumer is to simply apply more heat. The consumer may not apply enough heat to completely melt the crack-stix and melt the plastic. When completed the repair should look without any air bubbles or gaps. Dalton Enterprises requests all consumers to contact us directly for any other questions on this issue at 800-851-5606.

      Pricey and painstaking to install but seems great
      I bought this based on much research. But glad I did after seeing how other neighbors got their driveways "caulked" by professionals only for everything to peel out the following year. I got the thicker variant as well for larger joints. I cleaned and filled the joints with sand then used my grill propane with an extension hose and self-ignite hand torch to apply it ($20 hose and $15 torch from HD also). On tight joints I hammered down the string to make it fit and dip flush with the surface. I had to go inch by inch, helping the compound bond to the concrete with a screwdriver as it melted. But it forms a tight self leveling seal that will probably last a long time, unless the freeze/thaw will affect it which remains to be seen after this winter, however it can be reheated or added on to. The $60 torch they try to sell along with this material is useless, you will be on your knees or sitting on a bucket doing this job, each inch needs attention. It's a tradeoff but might save you from doing this every year or two, if indeed it will last that long (they say "permanent" solution). I tried to install it as well as I could heating the concrete and making sure the material boils into the crack and bonds to the concrete. Very large joins required 2 applications. I also tried their black material which is available at the local HD in small reels, it's much worse on concrete, tends to overflow the joint after it's hot and makes a mess, also much softer when it's hot outside, this grey stuff is decently hard to the touch except when very hot outside - it becomes a little soft. I recommend this over other products and over the black variant (which is better for asphalt driveway). It's quite aesthetic and blends in with the concrete especially if the concrete is new.

      It says there is 225 feet. There was actually about 175 feet. I needed about 20 feet more to finish my job. Not spending another $145 for 20 feet when I should have had more then enough with first purchase
