that. Prime with Kilz. It seals and covers smokers' walls just fine.
As far as the top down/bottom up controversy, it never goes away. Here's a
question that might make the answer obvious: How do you clean your kitchen
appliances or cabinets? Top down, right? Does it make any difference that there
are drips? No, because you get them as you go downward. I can't IMAGINE working
from bottom up and constantly having to go back and clean up drips. It seems
insane to me. All that extra work to re-clean a surface you just cleaned!
Totally different circumstances. Yes, on a car you wash from the
bottom up because washing a car is generally a two step process of
wash with soap followed by rinse. The reason to start at the bottom
is simply to keep the areas already washed wet until the rinse is
done. If you allow areas to dry in the process the rinse is not
likely to remove the dried on soap and dirt. Washing a wall isn't
normally a two step process.
The reason you start at the bottom and go up is because if you start
at the top and some of the water drips down the dry part wall it will
streak and those streaks are hard, if not impossible, to scrub off.
And I know from experience.

My Mom said that if you start at the top, the drips will make streaks and the
streaks will show when you finish washing the wall. I didn't believe her, washed
a wall from the top and the streaks made me crazy.
