I purchased this product because we needed to seal our artificial rock waterfall that’s a part of our pool. It worked great and covered all cracks without it appearing to look unnatural with the filling. This worked best on smaller cracks with not much weathering, but still does the job on the bigger cracks, just looks a little unnatural.

My biggest complaint is that if there is any oxidation in the concrete, this doesn’t last. It seemed to wear away within a couple weeks, definitely not worth it to keep filling the cracks on a close to mostly basis. Overall, if you’re looking to seal smaller cracks or some touch up work, this works like a miracle and I highly recommend.
