Customer Reviews for DAP 10.1 oz. Black Exterior Roofing Blacktop & Roof Sealant

Thank you for posting your feedback. We're sorry to see your low star review regarding DAP Roof Waterproof Asphalt Filler & Sealant. As indicated on the product package label and supporting product literature: "1. Cut nozzle at 45º angle to desired bead size. 2. Puncture inner foil seal. 3. Load cartridge into caulk gun. 4. Fill gap or crack with sealant." In order to properly dispense this product, the "inner foil seal" must be punctured. Failure to cut the nozzle and/or to puncture the inner foil seal will not permit the product the flow from the application tip as intended. If this foil seal is not properly punctured or the nozzle opening is cut too a very narrow diameter, it will create a too narrow of a restriction for the product to flow (without the use of excessive force). If the burst strength of the package is exceeded, product may leak from the rear of the cartridge (plunger). This is a fail-safe designed to prevent the cartridge wall from rupturing. This condition can also occur if the product has thickened due to exceeding its shelf life or if dried material is physically blocking the nozzle (between initial use/re-use attempts). Should you have any questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.
