Sure there is paint designed for basement walls and floors to help stop
water from leaking in. The only problem is it does not really work.
If you have water coming in, you first need to get it away from your
foundation. That means making sure the ground slopes away from the
foundation in all directions for at least ten feet. All downspouts need to
be directed away from the foundation and any walks drives or patios also
need to slope away from the foundation.
Next you may need to add additional work outside the foundation to seal
the foundation and remove water that gets that far. Last is draining the
water from around the inside of the foundation to a sump from which it is
...and, the fact is, if it *did* work, it could potentially cause bigger
problems. Imagine the scenario where you have significant water
accumulation around your foundation. But, you're happy because your walls
are completely sealed and your basement is dry. In effect, though, you have
turned your foundation walls into a dam holding back 8 feet of saturated mud
(or more). Do you think they're designed to withstand that force? (Hint:
No.) As Joseph M. says, it's much more advisable to remove the water from
the outside through other passive or mechanical means.
Epoxy is good for a concrete floor. For the walls, there is a
rubber-based concrete paint. It is good to seal the walls to keep the
basement as dry as possible. Make sure your grading around your home
is good for diverting water.
I am actually in the process of covering my basement walls with Drylock.
I am not doing it for water prevention as much as I am doing it for the
look as beige walls in a basement are a lot more attractive than grey
If you have water seeping through your walls you have problems that need
to be fixed from the outside.
You can seal the walls. This gives the wall a much better look than
concrete blocks. You may find it look good enough to the point that
you will not feel wanting to put a finishing wall over it -- this
means you can save a lot of work by not finishing the basement. As a
matter of fact, now that I have finished the basement, I find that I
am probably better off simply leaving the wall with DryLock paint
instead of finishing the basement -- saving time and money.
If you seal the wall, but leave the floor unsealed, any water reaches
the outside of the basement water will go further down, and show up on
the floor. This will make the water problem much more apparent; then
you can take the appropriate action to fix the water problem outside
your house (such as fixing the downsprout, ...etc) instead of waiting
until the problem showing up in the form of mold on your wall.
What I did in my unfinished side of my basement is to paint the wall
in DryLock, and then paint another coat of white paint that is
mold-resistent over the DryLock paint. You can stain the top coat to
any color you want.
I actually bought my DryLock in beige and it looks great. If you are
looking to do a quick cover job for appearance and not so much for
moisture I would buy the grey since you won't really see where you put it
on too thin.
