Will this work in joints in a sloped driveway? I have long expansion joints running parallel to the slope, but it's not super steep.
It says this product is paintable but it does not say that anywhere on the tube. Has anyone painted it with long term success?
In roadway, how long before heavy traffic can cross without damage to the caulking?
Will this stick to plastics such as vinyl?

Good product but you need to be careful if you have a slope

I had a wooden expansion joint that rotted out. I cleaned out the expansion joint and put in exterior foam, leaving about 1/2 inch for the self leveling sealant. I have a slight slope away from the house and just jammed some cardboard in the joint in a couple of spots until the sealant started setting up and then pulled out the cardboard and added a little more material. Don’t have more than a half inch (depth) space to fill, you’ll just waste material. It levels nicely but you have to manage any slope. It won’t stay put, it will run. It dries like flexible rubber. I used a 29oz tube and another half tube to do 18 feet by 1” wide by 1/2 “ deep.

Easy to apply

This product is not for sealing vertical cracks and joints, horizontal only. I have a few wide gaps between slabs in my driveway and I was told that could undermine it and cause it to sink. I got some sand and filled in the gaps, leaving a half inch depth at the top. You put this stuff in your caulking gun and then basically just pour it in. It's a little thicker than honey and it will flow and fill in the area so you don't need to be as precise as with regular caulk. Just move along, allowing the caulk to ooze out as you go. It is self leveling and self sealing because it flows and makes contact with all the sides. It is supposed to remain stretchy and keep the water out for a long time. I can't say anything about that because I only just applied it but it has dried to a rubbery consistency and it looks great.

works for cracked sidewalk

Worked great for sealing cracks in my sidewalk. Make sure to follow instructions as it does self-level.I bought several tubes. Fixed several cracks. The results look great and it has lasted through a full year cycle without failing so far.

PACKING DREADFUL

The product is fantastic, very happy with the result.Problem was Amazon shipping, 4 loose in a large box and the bad handling had bent all the nozzles, thankful none had broken off but the packing was dreadful
