Thank you for posting your feedback. We are sorry to see your low star review on DAP KWIK SEAL Kitchen and Bath Adhesive Caulk. This product is an acrylic-latex (water-based) formula, not a silicone-based formula. Based on your commentary, it would appear to indicate that you may be attempting to apply the sealant to an area where silicone and/or its residue may be present. Because silicone and its residue are classified as a "bond breaker" (a surface that is too slick to permit proper adhesion/bond formation), proper adhesion/product performance would not be expected. Because you did not provide any details regarding your project, it is difficult to provide you with a more specific reply or product recommendation 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 and to provide you with guidance on how to best proceed.
