We are so sorry you had this experience with our product. OSI QUAD MAX Sealant does have a higher viscosity than most sealants and requires a higher-quality caulking gun with a high hand thrust ratio. Additionally, it is important that the tube opening be cut large enough and the foil seal is broken before reattaching the nozzle. The nozzle opening should be at least ¼ inch or larger. It's also possible the product you have is past or near its expiration date.
