|General Electric Silicone Glue|
Whatever you want to call the title, here is the story.
For over a year now I have been bugging my landlords to fix the tiles in my bathroom.
They have tried to fix it twice, but both times they botched it and the silicone just breaks the next time I use the bathtub or shower. Note: I always waited at least 24 hours before using it again, but it breaks anyway.
Anywho, I think the reason why it keeps breaking has nothing to do with water usage in the bathtub or shower - it is afterall, waterproof silicone. What I think is happening is that the when the bathtub fills with water it WEIGHS more and this is an old building... when the bathtub weighs too much and the bottom tiles are literally glued to the bathtub using silicone, for whatever reason the bathtub sinks into ground a little further - only by a millimeter or so.
This causes the tiles to pull apart at the weakest point because it can't handle the extra weight. It is only a millimeter, but it is enough to break the silicone.
Now my landlords (bless them) have been fixing the tiles each time with the bathtub empty... so no extra weight in it. But they haven't heard my whole theory about the bathtub sinks an extra millimeter lower when its part way full of water (or even just has someone standing in it).
Thus every time they fixed it was fine up until the point where the bathtub had someone step into it or filled it with water.
So how did I manage to fix it myself???
I bought a $5 stick of General Electric Silicone Glue (roughly the size of a tube of toothpaste) from Canadian Tire, I filled the bathtub with water (for the weight) and then I fixed the cracks in the silicone myself.
Done. The next time I have a shower or a bath it shouldn't sink at all because now the bathtub is being held down instead of held up. That is my theory at least. We shall see if it works.
