Answer This Question
A:Â Thank you for posting your inquiry. For resealing the nozzle after use, DAP offers a reusable DAP CAP (sold separately). As a work-around, a small piece of plastic wrap or food grade plastic bag can be secured onto the tip with a rubber band (be sure to squeeze any excess air out before making the seal with the rubber band). Should you have additional questions or require additional guidance, please feel free to contact DAP Technical Customer Service at 888-327-8477.

Thank you for posting your feedback. We're sorry to see your low star review on DAP ALEX FLEX. We are not able to positively identify the nature of the discoloration based on the photographs/information that you have provided. The most common causes for discoloration are dirt pick-up prior to curing and/or biological contamination. Of note, it appears that there are also other areas/materials where similar discoloration is evident (vinyl/plastic weather stripping/trim), which would suggest that the discoloration is primarily biological in nature. Because you did not provide any background regarding your project, application technique or application conditions, we are not able to provide a proper response in this format. Should you wish to provide this information, so we can address your concerns, please feel free to contact DAP's Technical Customer Service Department at 888-327-8477.

Thank you for posting your feedback. We're sorry to see your low star review on DAP ALEX FLEX. Based on your commentary and the attached photograph, the issue that you are describing would appear to be related to the presence of a bond-breaker (silicone sealant and/or its residue), not the paintability of ALEX FLEX. Because you did not provide enough details about your application, it is difficult to provide a more detailed response or specific corrective 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.

This is the best caulk I had and I’ve had lots of different caulks in my day. Thick, strong, and lasts a long time.
