Thank you for posting your feedback. We are sorry to see your low star review on DAP Maxfill Expanding Sealant. Because this product must be dispensed in the upside down position, the use of spray foams in overhead applications care not recommended. As indicated on the product package label and supporting product literature: “CLEAN-UP: Uncured foam can be cleaned from most surfaces with Foam Cleaner or acetone. Cured foam must be removed mechanically from surfaces. If wet foam contacts skin, clean immediately with a dry rag – do not use water – water accelerates curing. Should you have additional questions or require additional guidance, please feel free to contact DAP Technical Customer Service at 888-327-8477.
