Thank you for posting your feedback. We're sorry to see your low star review on DAP Kwik Seal Ultra. Kwik Seal Ultra (Clear) applies white and dries clear in 7-14 days (depending on joint depth, temperature and humidity). It is an acrylic-latex (water-based) chemistry, accordingly, the sole drying mechanism is the evaporation of water. Dry time can be significantly impacted by cool or humid application conditions, moisture in the application surfaces or by thick (deep) applications of the sealant. Clear acrylic-latex sealants cannot turn clear until all of the water contained in them has evaporated. Because you did not provide any project details, such as: size of the joint, application surfaces, surface preparation, application technique, application conditions or the amount of time since the product was applied, it is difficult to provide a proper response 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.
