Thank you for posting your feedback. We are sorry to hear of your frustration using the DAP Latex Window Glazing.This is a significantly different formula in terms of both chemistry and user experience (when compared to traditional putty-style, oil-based products, such as '33' Glazing). By design, this formula is intended to apply very similarly to a traditional caulking compound. Because you did not provide any details regarding your attempted application, such as, temperature, humidity, surface materials, surface preparation, fill depths or any information regarding your application technique, it is difficult to provide you with a proper reply or any specific product usage guidance in this format. At your convenience, please contact DAP’s Technical Customer Service Department at 888-327-8477 so that we can obtain some additional information from you regarding your experience.
