If done in warm weather you can stretch the length to a smaller diameter
Yes it does i had a special project that sealed it up 600' of steal angle to cement.
yes, this product is commonly used on concrete pool deck.
Probably only about 1/2" so if you have a larger crack you will need to put in one or more strings of this product but it will all melt together with no problem.
I used a small torch with mapp gas & it worked very well.
I laid about 200 ft. I was disappointed to see the stuff itself cracked, receded from both sides of the joint where it contacts the cement. Putting tar over it is an excellent idea for a good seal. I have seen other stuff that seems to stay more pliable, but it's a lot more expensive. I really don't see why the tar would not adhere.
From my experiences with this it work great on slabs that don't move in changing seasons -the surface need to be very clean before melting the product in -best is to scuff the surface up some to remove any sealants, oils or other contaminants.
Put Crack-Stix in 2 years ago, used it in expansion joints without issue (if it's a large gap fill it with sand first to bring the gap about 1/2 to 3/4 from the top than melt the crack-stix in place). Temperatures here range from 90 degrees in the summer and zero in the winter. A contractor in the plaza where I work turned me on to this product, it's been in place 5+ years and is still as good as the day it was put down...
I used the 20lb tank on a hand truck and a larger torch
I used this for that exact purpose. The only issue would be if you have any pvc expansion joints that could possibly melt due to the heat it takes to apply this product. I did not have that issue but wanted you to be aware of this potential problem. There are self leveling sealants that can be used if you have this issue. My problem with those products is they don’t hold up as well in areas where you have freezing and thawing conditions.
