In today’s video, I’m going to be sharing
how to waterproof basement walls using DRYLOK Paint. Now here’s the deal, UGL is sponsoring
this video. And the reason why I agreed to partner with them was because I’m going
to be doing this anyway. So I figured I’m doing this anyway, we might as well partner
together, and show you how to use DRYLOK Paint. Before you actually waterproof basement walls,
you want to assess the outside of the home first. Now I’m just a handyman. I’m not
some kind of basement waterproofing expert. But I do know a few different things. Number
one, you want the land around your home to be sloped away from the house. This home is
landlocked here in Pittsburgh because it’s sandwiched in between two other homes. We’ve
got a sidewalk on one side and a yard in the other. And there’s not too much I can do
with the grading. Number two, you always want to check and make sure that your gutters and
downspouts are clean. I clean those twice a year, and I know that they work properly,
yet we still get moisture in this basement. So I’m going to be renting out this home.
I wanted the walls to look good for the new tenants, and I didn’t want it to have that
musty smell. So that’s why I’m using the DRYLOK Paint.
As you can see here, the house is in fact landlocked. There’s that sidewalk on the
side of it. And that sidewalk where that window is leads down into the basement. So we would
run this dehumidifier which costs money, and my tenants wouldn’t run it all the time.
Here’s the main wall. Here’s the side wall; you can see all the cracks in it that
we’re going to fix with a special product from UGL. I’ll get into that in a second.
I’m just using a regular 6” drywall knife, and I’m going to be using that to scrape
off any of the old paint, any kind of efflorescence that’s on the wall. You should use an etcher
of some type if you do have efflorescence down. In this case, I’m using a Sawtech
blade and an angle grinder. And I’m taking off some of the high spots on the wall. You
don’t necessarily to do this. I wanted to do it, though, to create a nice, smooth finish
in certain spots. This is a really old wall, and it did present some issues in terms of
the prep work. Wear all your safety stuff when you’re doing this. And then wipe off
the wall with a broom so there isn’t any dust on it. So this is what my prepped wall
looked like, and I was ready to go ahead and do some additional work.
This is the DRYLOK Fast Plug. It’s a hydraulic cement, and you can use it to seal any kind
of cracks. You can do this actually under water. And you can also use it to anchor posts
and different things. The other nice thing is it does reduce radon gas penetration, and
that’s important here in Western Pennsylvania where radon is pretty bad.
Now what you do is you take three cups, three measuring cups provided in the container.
Three of those and one cup of water, and you mix it all together with a putty knife. Now
the colder the water, the better the working time for this hydraulic cement. And you just
fill in any kind of spots on the wall. Now you do want to cut out a v-notch in any crack
because that v-notch will help hold the hydraulic cement in the wall. But as you can see here,
I’m filling in all the cracks. Then if you want to, you can actually use a masonry brush
to feather out that finish and make it look a little bit better. So that’s what I did
there. I didn’t want like this huge, weird patch on the wall.
Now if you do have mold or mildew, you can use Concrobium in the corners, and that’s
exactly what I’m doing. Now here’s my prepped wall before I go ahead and apply the
DRYLOK paint. So as you can see here I filled in all the cracks, and everything is as clean
as possible. And this dehumidifier was in fact running while I was doing all this. So
hopefully we won’t have to have that happen anymore.
So open up your window in the basement. If you’ve got a window, you want to air everything
out. If you do have a forced air furnace with gas, I would recommend that you turn the gas
off to it. Same thing with the hot water tank just as a precaution. This is, after all,
paint. And if you’ve got a gas dryer, don’t run it while you’re painting in the basement
too. So again, we’ve got plenty of air circulation in here, and that’s really, really important
when you’re working with any paint. So I threw a drop cloth on the floor just
to protect the floor even though it doesn’t look the best—just any normal drop cloth.
Now you can also use a ¾” inch nap roller. I was going to use a 1 ¼” nap roller but
decided that actually I wasn’t going to do this because a paint brush might be a better
option, and I’ll get into that in a second. So I’m using DRYLOK Extreme Masonry Waterproofer
for this project. It provides a smooth finish. It also provides a mildew resistant film on
the top of the wall. And you can tint this to any color you want. So you don’t have
to do this in white. You can use it for a variety of different surfaces and areas in
your home, so not just the basement but swimming pools and other locations. I would say, you
know, make sure you follow the directions. You want it to be relatively dry in your basement
when you do this. DRYLOK does sell brushes, and that’s what I decided to use.
So you just want to mix up the DRYLOK really, really, really, really well. It is a thick
consistency, but not thicker than a regular latex paint.
So I just started in the corner and brushed it in right next to that electrical box. And
as you can see here, I started by just moving back and forth, left to right, and trying
to fill in any areas that needed the paint. And I found that moving left to right and
horizontally was a good method. You don’t want any pinholes in the paint because that
will let moisture through. So just double check that you don’t have those pinholes.
So again, I just moved left to right across the wall, and this went by pretty quickly.
You know there’s really not much to it. You just want to make sure that you fill in
the best that you can with the DRYLOK Paint. I like the paint brush because it allows me
to go back and forth. And if I do have any kind of drips, I can take care of those. You
can spray DRYLOK on the wall. And I almost did that but decided not to do it because
of all these weird nooks and crannies, like behind pipes and supports in the wall. It
was just easier for me to do that. And like I said, I back brushed any of the drips and
the runs that I had on that block. So the first wall, it probably took me a good
hour to do that; maybe less. And then because DRYLOK is a latex paint, you can actually
apply it to any surface. So I actually did the wood where that panel’s located. And
then I let that hydraulic cement dry overnight, and I just filled that in with the DRYLOK.
You can see this wall looks terrible. And then after I painted it with the DRYLOK, it
looks so much better and way more presentable to the tenants who are going to move in here.
Just remember: To get the full benefit of DRYLOK, you need two coats on the wall.
I was pretty impressed with how easily the DRYLOK went on the block wall here in this
old basement. Now if you’re going to be waterproofing a basement for a game room or
perhaps a basement bathroom, I would recommend that you check out DRYLOK Paint. It’s a
great option for you. It’s not terribly expensive. And again, it’s a great DIY project.

Thanks for watching today’s video. I’ll see you next week. Take care, and talk to
