Thank you for posting your feedback. We are sorry to see your low star review on DAP Dynaflex 230 Premium Elastomeric Sealant. Because you did not provide any details regarding your application, such as application surfaces/condition, bead size, temperature, humidity, or application technique, it is difficult to provide you with a more detailed reply or any specific product usage guidance in this format. DAP also offers a line of fast cure sealants, such as DAP AMP High Performance Window, Door, Siding & Trim Sealant, for use under more difficult application conditions or for projects that require faster "return to service times". 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 and so that we can discuss alternative product options that may be better aligned with your needs.
