10 lb. 125 ft. Medium Black Permanent Blacktop Crack Filler

Yes, a weed burner torch is suitable.

i would get the bigger one and drip fill the smaller cracks... i hold the stick above the crack and heat it with a torch allowing the filler to drip into the crack... for the larger openings fill the base with some rocks and then stuff the filler in and melt...

Does not make a difference because you can push either one into the cracks and level it once you torch it.

You can double it up or stretch it out so either size will work. I would buy the size that fits the majority of the cracks you have.

1/2 inch works best.

I think we bought the 1/2" as we had a number of cracks that were an inch wide. We doubled them and it worked out pretty good. However, cracks will continue to occur over time. I would buy both if you need them both sizes as you will likely have leftovers tor future use or touch ups. Things always go smoother and faster if you can use the proper size. Otherwise you spend more time trying to adapt the product which sometimes is more of a hassle. But. too wide is easier to work with than not wide enough.

We doubled up for the bigger cracks so we didn’t have to buy two different sizes. 

No, as long as the proper torch is used and the directions are followed.

Yes, if flame applied directly at a string. This product is oil-based.

Can but not recommended. Ideally you would want to apply in the summer when the black top is hot, warm at least. This would reduce a heat loss and ensure better bond of liquified hot product with the black top.

Yes, as long as there is not a frost in the ground. We recommend preheating the asphalt to get rid of any moisture before applying.

Depends on the type. Propane plumbing torches are not designed to work upside down, so they often go out when they are inverted to heat the crack.

Bernzomatic TS8000 torch would work as it is able to function upside down.

Tried a heat gun at 1500W setting. A major waste of time and energy if you ask me...USE propane torch.

This product takes a great deal of heat to melt into the cracks. I used a large propane torch and a heated square shovel to guide the product into the cracks. Using a heat gun might work but if you have a large area to cover it might take a considerable amount of time.

I'm not sure if it will heat up hot enough and you don't want to put that strain on your electrical system either- assuming you will be using a drop cord and outlet on your house.

I would suggest no. Unless you have a lot of spare time on your hands. It needs to be heated to a high temp to fill and adhere to asphalt.

I used a torch. I believe one may use a heat gun if the gun temperature is variable and will get hot enough.

A soldering iron works pretty good. Just cut off a foot long piece at a time to work with and solder it into the crack. Use a heated metal putty knife to smooth it out better for wide cracks.

Yes, a commercial grade heat gun would work.

Yes, typically heat guns take longer to melt the product.

The heat gun will certanly melt this product, but it is NOT effective tool in crack sealing application. You need a heat source hot enough to warm up the area around the crack. Propane torch is what you WANT to use.

Yes, but the cane torch works much better and is easier on the back

I don't think in will. Heat gun will not get hot enough.

OK, did some research. An electric heat gun creates a temperature of around 1100F while propane burns at twice that temp. Guess that’s a no.

Yes. Electric heat gun not a hair blow dryer.

Well I have not tried it with a heat gun personally but I would say yes, it would be very slow going though. I used a 5 gallon tank of propane and a weed burner that works great, I also used a small hand held blue propane tanks in tight spots but that slow going so I would imagine a heat gun would work but very very slow.

yes

Yes, if you can fit it into the void the material will bond to the Belgian block.

Hi Jeff, It's not made for driveway edges. It works best on cracks that have borders around them. However, I have used it on some of my edges and they seem to be holding up even without a border. Since you have belgian block borders, it would probably work well for you. I usually use them on cracks that are about 2-3 inches in and parallel to the edge of the drive or that run horizontally across the driveway and it works great. The repairs have held up for almost two years now. The repairs are noticeable so its best to use the Crack-stix before you put down driveway sealer so that they will blend in. I also strongly suggest that you purchase an outdoor weed torch to melt the sticks with. It will save you a lot of back bending and make the job much easier. The torches cost between $30 and $60 depending on where you get them. They all work about the same so I don't think that getting a more expensive one buys you anything. All in all, its a good product so I think you will like it. Good luck with your project.

You have to place the material into the cracks and then melt it in with a torch. When melted it will flow into cracks. It might bleed into your blocks. Test it in an inconspicuous area.

Yes, I used it to fill in the driveway gap at my clients home. I have used it for driveway cracks as well. I love it.
