Has anyone tried Sealmaster Flexmaster one gallon pour crack filler. I currently use a common cold pour crack and trowel crack filler. I am always looking for a better product and this one has caught my eye. It is about twice as expensive as the product I am using, I would like to know if it is worth the price in results. I know hot pour crack filler is the best, but because of the amount of time it take to properly heat the product, I only offer hot pour on commercial parking lots.
