Thank you for posting your feedback. We are sorry to see your low star review on DAP Kwik Seal Plus Kitchen and Bath Caulk. When applied as directed the product will meet or exceed its performance claims, however, as this is an acrylic-latex (water based) formulas even small variations in air temperature, surface temperature, relative humidity and dryness of the application area can have a significant impact on the product's performance development. At 18 hours, the product is designed to be "water ready", however, it has not yet reached full performance. Likewise, bond-breakers (typically silicone and silicone residue) will prevent proper adhesion, thereby allowing water to bypass the sealant, resulting in softening and potential leakage. For more demanding application and faster return to service times DAP offers AMP Advanced Kitchen and Bath Sealant, however, these formulas are typically more challenging to apply as they require solvent for clean-up. Because your post was essentially a critique of other review responses. and did not contain any details specific to your attempted application, it is difficult to offer a more specific response in this format. Should you wish to provide us with this information, so we can better address your concerns, or to recommend a more appropriate product, please contact DAP’s Technical Customer Service Department at 888-327-8477.
