Please make a follow-up video next year on how well this method holds up over a winter. Does the manf. allow use of sand to fill up the hole? Top off with self leveling sealant then apply this on top?
The instructions stated for for cracks over a 1/16, fill with an approved asphalt sealant. I believe the concept is just to prevent the product from melting down in the crack, you can see it did that in my video where It was wide in a few places and I didn't get it prefilled. I wouldn't use sand as it could hold water and expand if frozen. For sure will do a follow up
If I have to do it again, I would look for a polyurethane based sealant to prefil the wider gaps and if it was super deep use foam backer rod first. I did this to seal an expansion joint on a video I have comming up and worked nicely and dried very hard.
All those are possibilities, but I don't believe they would work well due to the nature of asphalt. Asphalt expands and contracts with changes in tempurature, so you want something that has some flex to it. I recently used a polyurethane sealant called sikaflex to seal between the garage apron and the driveway that I think I will use in the future to back fill larger cracks(depending on it holds up this winter). Then I'll use the tape over the top as it has heldup well so far this winter.
Thanks for watching everyone, I hope you enjoy🍻🍻

good job 👍👍👍💚💜

Have you ever considered using concrete, mortar, or polymeric sand to fill in the cracks?
