Q:can I use this around my toilet to seal it to the tile? OK
by|Jan 18, 2024
1 Answer
Answer This Question
A: Thank you for posting your inquiry. DAP DYNAFLEX 230 is not tested, marketed or recommended for use in bath or kitchen applications. The application of a sealant to the base of the toilet would not be recommended if leaking is observed, as it will likely trap moisture, which can lead to more significant problems such as mold/mildew, and rot. Should you have any additional questions or require further assistance, please contact DAP’s Technical Customer Service Department at 888-327-8477.
