This caulk has excellent adhesion and flexibility. I purchased this after watching a YouTube of caulk comparisons with best flexibility and this one rated the best.

Why is the 230 Gray color so difficult to find. It matches Cape Cod Gray, a popular color for sure. Get with it. Regarding the product, it covers well, easy paint over. Excellent overall

Thank you for posting your feedback on DAP DYNAFLEX 230 (Clear). As indicated on the product package label and supporting product literature (in BOLD text): "Sealant applies white and dries clear in 7-14 days depending on joint depth, temperature and humidity.” All of DAP's (CLEAR) acrylic-latex (water-based) sealants will function this way and are labeled accordingly with the information found above, regarding this color changing performance characteristic. Should you have any additional questions or wish to discuss this, please contact DAP’s Technical Customer Service Department at 888-327-8477. DAP

I always use this when I need a clear caulk. Applies well, sticks nicely and dries fairly quickly. Recommended.

Formula 230 is SO easy to use, water clean up. Smooths out perfectly, stretches well when dry. Improve the quality of your paint jobs, buy the good stuff.

    The consistency between various batches is uneven with some being very "runny" so much harder to apply.

    Thank you for posting your feedback. We are sorry to see your low star review on DAP Dynaflex 230 Premium Window Door Trim & Siding Sealant. While it is common for high performance (elastomeric sealants) to feel "softer/thinner" than general purpose sealants, the "runny" texture/consistency indicated in your commentary is not expected (unless the product is being applied in large volume fills vertically/overhead and/or out of temperature range). 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. When calling in, please have the product package available, as we will need to collect production information from it. DAP

    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.
