I was concerned with the price for mere residential use, but this stuff is amazing. It fixes cracks and fills spots that big-box store products fail on. It bonds very strongly with existing concrete. It cures very fast, so only mix small batches and work fast.

Great joint compound. Easy to use. Cures very fast even in cold temperatures. Very happy with the end results.
