We have two bathrooms with full size bathtubs surrounded by ceramic tile
walls. We have lived in this house for 11 years now, and for this time
I caulked the tubs every 3-4 years when the old caulk developed cracks
and started getting loose from the tub or wall. The job was always
quite easy: remove the old caulk, wipe the area clean of dust and
grease, and recaulk. I can not remember what kind of caulk I was using,
but it was standard home store stuff advertised for this purpose.
Now over the past year it seems that this does not work any more. I have
had to replace the caulk every 2-3 months when it starts developing
cracks again. Every time I have carefully removed the old caulk and
cleaned out the surfaces prior to putting in the new caulk. I have also
tried three different manufacturer's products with no improvement in the
Here are my questions:
1. Is there one brand or composition of bathroom caulk that has
significantly better adhesion than the others?
2. Any specific chemical or detergent wash recommended for preparing the
surfaces for better adhesion?
3. What else that might be causing this? We live in suburban Chicago,
so we have not had earthquakes or such recently either.
Appreciate any helpful ideas.
