Denver Decorative Concrete & Custom MasonryCan I mix concrete and premium driveway sealer to form a strong but flexible patch?
Here’s the plan. If I take crack resistant cement mix and add acrylic fortifier to make a very thick concrete mix and then mix it with asphalt sealer (premium kind with polymers) in the ratio of two parts acrylic fortified concrete mix to one part driveway sealer, mix well and apply to the weaker parts of the blacktop that have either formed depressions or shallow potholes. Do you think this fix will provide the flexibility of acrylic and polymer asphalt and the strength of concrete. Has anyone tried this? How about re-sufacing the entire driveway with this mix (about 1/4 to 1/2 inch thick)? Please let me know what you think.
Gary, thanks for sharing your experience. Would you be able to recommend the minimum thickness for the cold patch when using in depressed area? I have heard some say that 2 is minimum. Any experience with QPR brand cold path?
When you tried mixing the sealer and concrete, would you happen to know the proprtions that you used? I don’t mean to bother you, but if I can learn something from you experience, that would be great for me and for all users of this sight. I plan making a youtube video to share my experience with everyone, I’ll also post that information on yahoo answers as well. Thanks again.
That could very well work. I haven’t spent a lot of time thinking about this subject, as my driveway is crushed limestone the whole length, but if I had an asphalt drive, I’d try this. I live in S. MI and our seasons are hell on asphalt, especially if it’s not on a good solid base. Way too much heaving and thawing going on in the spring. Your solution could lead to a whole brand new product if it works. Give it a try. Nothing ventured, nothing gained, as the old saying goes. Good luck
I tried that once. It didn’t work all that well The concrete never really got hard. What I found that works in that situation is to simply fill the crack with concrete and then coat the patch with the sealer.
I think trying to coat the driveway with the mix you suggest might make a bigger problem then you have now. The concrete will not be enough to add much strength. I have coated a driveway with a mix of driveway sealer and just plane sand to level out dips and cracks and that worked reasonably well. Also I have chiseled out broken asphalt and used asphalt patching material to fill in the hole but used a propane torch to soften the stuff so it fills the hole better. You have to be careful with that as the stuff will burn and I am sure the manufacturer will not like you doing that and I tell you right out it could be dangerous so you’d be doing that at your own risk.
Cementicious concrete (portland or gypsum cement admixture) requires water to cure. Adding solvent-based hydrocarbons will defeat the process and create a sludge that will be neither fish nor fowl – not a sealer and not a concrete.
Do not do it.
no it will mix but will chemically react on account of different properties not a pretty sight
I would think that you’d want a very small aggregate in your concrete mixture in order to spread such a thin coating on your driveway. I would be concerned that the chemical reaction of the Portland cement would be adversely affected by the chemicals in the asphalt emulsion.
I would suggest taking a bag of cold-patch and a bag of post-hole concrete mix and doing an experiment on a piece of plywood. See if it would harden up and then try running over your test area to see if you develop cracking.
Never know somethings until you give it a try!
