What is the difference between hot-pour and cold- pour crack sealants?
Hot-pour crack sealer is melted and applied, then cools to a pliable, rubber-like consistency, allowing it to expand and contract with the crack. Cold-pour crack sealers can be a water or asphalt based product that is applied to cracks in a liquid form, and then dries to a solid. Cold-pour crack sealers usually do not perform as well, due to their lack of flexibility when dried.
