Silicone Caulking

Q: We applied tile to our bathtub walls. The DAP I used for caulking keeps melting away from the joints. I have reapplied 3 times and it keeps coming away. My daughter has the same problem with her plastic tub surround. They even filled the tub and then reapplied the caulking. Is there a problem with this brand of caulking? What do you suggest?

A: Your information would indicate that you are using a DAP acrylic latex caulking. My recommendation is to use bathroom silicone caulking either DAP, G/E or Bulldog brand. Please ensure that the surface is clean and dry before application.
