Sashco 16210 Slab Concrete Crack Repair Sealant, 10.5 oz Cartridge, Gray (Pack of 1)

This has held up through all 4 seasons on my very old, cracked driveway. It was a lot of work to prepare the cracks, I used a steel brush, pushed a foam rod filler in, then the sealant. In some cracks I had a problem with the foam not staying down, so I just used the sealant. It has a sunken appearance in those areas, but has stayed adhered to the edges of the cracks. My cracks ranged from 1/4" to well over 1' (large ones I used 2 foam rods side by side). I used a LOT more sealant than I thought I needed, but if it will last for years, it will be worth it.

To give you a frame of reference, I had to watch a YouTube video to figure out how to use my caulk gun before I got to work. So, if you're looking for an expert review of how this performs compared to other similar products, look elsewhere.This stuff is really easy for a noob to work with, so if you're feeling insecure about your skills, go for it. It goes into the crack thick and clingy, even at a vertical angle. More importantly, the excess is really easy to smooth and wipe/wash away. You have PLENTY of time to clean up your work before it dries. When it dries, it shrinks, has kind of a rubbery caulk-y texture, and it holds even completely severed pieces together snugly. The color is a middle grey and would match most concretes well. It's just a very forgiving product with a nice finished result.

I've tried a handful of different similar products. I like the color and texture of this the best. It's the only one that actually matches the color of my driveway. Other review claims are true - it does take a LONG time (days) for this stuff to solidify. However, I'm putting it in driveway cracks, where it isn't touched, so it doesn't matter that it takes a while to dry. It rained the day after I applied it, but the rain didn't seem to negatively impact the stuff. Overall, it's the best one I've tried. I just ordered a 2nd tube to fill cracks on my back patio.

It never sets up. Save your money. Dont buy this stuff. The only reason I didn't rate it a zero is because I couldn't. Followed directions to the letter. Spoke with a service rep several times. Now I have to pull up the flooring, dig the guck out and start over again. Wish I could get my money back not to mention the time we lost on the project. Seriously, dont buy this stuff.

I purchased this product last year and applied to the cracks in my concrete. The color was fine and I was satisfied after the job was finished. Unfortunately, this summer the color of the sealant turned very dark almost black. It looks very bad and I will have to apply different product over this sealant to hide its dark color. I will never use this product again.

very elastic, however matches my mortar nearly perfectly. great adhesion and coverage. Highly recommend for filling vertical gaps. Would not be good for repairing lifted/crack broken driveway, But would be excellent for filling driveway or sidewalk expansion joints.

We have bought multiple cases to use to fill cracks in patio and absolutely love it! Was buying at OSH but since they are going out of business started buying here and found its a better price when you buy by the case. Highly recommend it for home projects to fill cracks. Started using it a year ago and cant tell any difference in old work and recent work.

Cure time is unmanageable! Applied it and after 48 hours is still to soft to even walk on...its the same consistency as when it came out of tube.. I asked company for help...no reply. Now considering removing. Be careful if cure time is an issue.
