Forum Title: Hot vs cold crack sealer
I understand the overall difference in material between hot rubber and cold poured crack sealer. I have been noticing though that seal coat does not stick well to hot rubber sealant. Especially in hot temperatures when the hot rubber begins to soften car tires leave tracks in it and turning wheels shear off seal coat. Recently I sealcoated and striped a parking lot that had hot rubber applied to cracks on almost every striped line. I feel the sealcoat and paint are going to start coming off real soon. Also the band left on the surface isn’t the prettiest to look at. Just wonder if any of you use cold poured material instead and are some of these issues avoided. Was looking at Flex Crac from AllStates Coatings which looks to be a higher end cold poured material. Just looking for input from others on what they have found.

Only time I use cold is on residential stuff. If I was to consider cold pour on a large scale like commercial I think I’d look into the pumping system UPM sells. It has a pump that you set in a 55 gallon drum and then a hose andcwand attachment much like one of the pull behind hit pour melters. If I remember correctly it was around 5-7k for that system but I could be wrong

For cold pour, I really like Kold Flo by UPM. That being said, I don’t feel there is a good comparison between hot and cold. Hot usually adheres better and just does a better job overall. Keep in mind you want it to be flexible so it can expand and contract as the pavement moves, but the trade off is getting something to stick to it. It would be like dipping a rubber band in paint, letting it dry, then stretching it. The paint will pop right off. There is no real fix for this, so I’ve found it best to just educate your client before. We give a “what to expect” sheet. Sometimes sealer sticks longer, but inevitably it comes off.

From what I have seen the cold pour doesn’t seal up like hot applied and does not last nearly as long. Also you need to factor in the cost factor vs hot applied and most cold pour needs to sit 24 hours before you seal over it.
