Some of you may remember that a while back I posted about a plumbing
problem in a shower enclosure. Couldn't find the leak and neither could
the plumber. Simple reason - it wasn't in the pipes!
Now I knew absolutely nothing about tile setting. But I accidentally ran
across a reference to sealing the grout. I knew the shower had been re-
grouted just before we bought the house. But I didn't know if it had
been sealed. So I ran a garden hose in through a window and sprayed it
on the walls. Eureka - it leaked!
Went to Home Depot and bought some spray cans of sealer, covered
everything I didn't want to seal, and liberally sprayed the walls. The
shower no longer leaks and I now know a little bit more about tile than I
All problems are obvious *after* the solution is found :-).
Don't want to be a Debbie Downer, but if the shower is leaking through
the grout, there are bigger problems than grout sealer. The purpose of
grout sealer is really to prevent mold in the grout. The wall behind
the tile should be water proof to begin with. One should be able to
spray water onto a properly prepared subsurface for tile, without tile,
and not have any leaks. In other words the subsurface should be

Yes, after I started looking I learned that as well. But this house was
built in 1956. I don't know if the same building codes were in effect
back then. But I do know the walls are still standing. At my age, they
don't have to last a whole lot longer :-). And no damage is visible from
the basement below the shower.
But even if the subsurface isn't waterproof, the sealer is keeping it dry
so that would seem to eliminate the problem.
OTOH, I also replaced the caulking between the walls and the shower pan,
so that may have been the problem instead of the grout. Either way the
leak is gone so we're happy.
Yep. Why gawd made "RedGard":
