How to Prep, Prime, & Paint Concrete Foundations | DIY Home Improvement


Welcome back to Albany County Fasteners – Fasteners 101. I’m Bob and today, I’m going to show you how to prep, prime,
and paint this garage foundation wall in my garage. But before get started, please subscribe, like, and share my videos. Leave a comment if you
have questions. We’re more than happy to answer them. Hit the bell so we can tell you when we have new content. So let’s get started. This wall is pretty clean. We have some spackle here. There’s several ways that you can remove this spackle. You can just take a hammer and hit it or scrape it off. Most of this area is all clean. We have
some over spackle here. In this situation, when we have this, you take a knife and you want to score this area. So you don’t start cracking the corner bead and everything else. You just clean off the area. See right below there they have the
corner bead. I’ll take care of that later. You can see it here. So they didn’t trim the corner bead off the end. They should of snipped that with a snips. That’s why you have that there but I’ll take a snips and I’ll snip that off. There should be no grease or oils on your foundation. If you have a chalk line mark, that’s fine. I can use a screwdriver or a scraper to scrape it off so it’s not under the paint. I happen to have a screwdriver here
right now. This all looks good. You’re gonna want to take this dust off of
here, we’re painting that. You want to clean that off. Yeah, a scrapper would be better. Unfortunately, I don’t have one here.
I thought I did, but I don’t. It’s at the office. That’ll be it. So one of the things you’re going to want to do before you get started is clean up around where you will edge. So you see this debris? If you’re edging or rolling and your roller goes too far it could hit that debris and put it on the wall. So you want to make sure that you’re
cleaning this stuff up. Take a broom… …and lessen any chance of debris getting into the brush or the roller. So I have here what I’m gonna need to do this project. Basically I have some roller pans, I have some roller liners (I bought a pack of five) they’ll be for different applications so I’m going to throw this out, I have some mixing sticks, a couple of rollers… That is the paint for the
staircase which is right over there. I have a brush container so I can walk
around and do the edging. It’s also so I can paint the stairs because very little
of that stairway will get rolled. I have a two and a half inch brush here. I have, let’s
see here, This is the primer that I’ll put on the concrete wall first; and this is Sherwin Williams exterior acrylic latex paint. These are both latex based paints.
A pair of gloves, the roller, a screwdriver, and a hammer. The hammer is basically to put the top back on. You’re gonna want to get a towel and put it over so when you hit the top of the can it doesn’t splatter all over. Also, wear shitty clothes. You want to wear clothes that you’re going to be throwing out or using for another project. Because you will get paint on them. So I’m going to open these cans up and I’m going to start to apply the edging with the paintbrush. So let’s get that rolling. So I have here a can of my primer. Which is just white paint. I’m going to get my stick and check it to see if there’s any lumps. Anything that doesn’t look right. If you want to thin this out a little bit you can, but when you’re doing trim first I recommend you don’t thin it out. You may want to thin it a little bit with a
little water when we start rolling. You’ll find primer is a little more pasty.
You can work out of this can if you want to. That’s up to you. I prefer to walk around. The small one is easier to work with. You want to go heavy when you trim it because concrete
has all these pores that you’re trying to fill. The idea of trimming is so when you’re rolling you don’t hit the other similar surfaces. Which in this case would be drywall and you really don’t want to make your white wall gray because that’s the color I’m going to end up with here. If you tap it like I’m doing here it fills those holes in the concrete. I like to give myself extra room but that’s up to you. A good length is the length of this brush. Which is about two and a half inches that you want from the top down and a little bit more. Always works better. Never overfill your brush, especially if you’re gonna thin out your tank because then it’ll drip. We’re trying to get a nice coat on here.
This is the primer, not the finish coat. This is just to stop the absorption of the paint when you put the paint on. Alright, that side is trimmed out. Now I’m gonna work my way around. So I have a little water here. Just going to pour it in there a little bit and I’m going to mix this up now. Thin it out a little bit here. When you do that you have to make sure you mix it very well. That you’re getting the water into the paint. Make sure that some of it isn’t more watery than the rest of the paint. If you let it drip like I just showed
you, you’ll see a consistency instead of a globbing. You’ll see a steady flow. Which is a nice consistency when you’re gonna be rolling the paint. Always make sure you scrape the bottom of the paint can. There’s a lot of pigments settled down there. Keep the plastic bag the roller comes with because we’re going to put the roller back in it when we’re done. Don’t try to rip it off.
Open it up on the end, like this here. Okay, you just open up the end, slide it off, and keep the bag. Don’t lay your roller on the ground. I’m gonna pour some paint in here that we’re going to roll on now. I’ll use the brush to clean up any drips. You don’t want to dry the roller out too much. You want to keep a nice layer on it. This is just a sealer. Basically I’m pouring the rest of the paint back into the can because I’m done for today. We’ll let this dry overnight and
tomorrow we’ll come back again. As that’s happening I’m going to
show you now how to save your roller. So you do not need to buy another one or use another one. So basically you’re going to take your roller and you’re going to slide the plastic bag over it. It’s a little messy, but no need to buy another roller. We can use this roller tomorrow to continue rolling the other side. Now you will get some paint in there. Then you take it and wrap it around that so it’s closed. It stays closed like that. That’s it.
You just leave it like that overnight. Now I’m going to close this top, but before I do that I’m going to take some paper towels, or a rag, and just place it over the top
like this before I knock this lid on. So it doesn’t splatter all over the place. That’s it. Throw this out, and I’ll see you tomorrow. Okay and I’m back the next day. My primer is all dry. You’ll see here that I did some masking along the drywall. Now I’m going to apply the gray paint over the sealer that I put on the concrete wall. So let’s get started with the grey paint on the wall. First thing I’m going to do is trim out the wall with the gray paint, and then we’re going to roll it. So this is my gray paint. I’m going to
open it. When opening a can, instead of doing this, turn it. Turn the screwdriver as you go around. It’s more effective. That’s the gray I’m going to be using. When it drys, it’ll dry darker. I’m going to mix it… The finished paint will spread easier now that the sealer is on the concrete. A lot easier. The primer is like a sealer. This is pretty well mixed. I haven’t seen
any different colors. If there was pigment on the bottom of the can you would see it down at the bottom of the stick. I don’t see it so this is pretty well
mixed. So let’s get trimming. You see that this is going pretty quickly now. The primer that’s on that wall seals the concrete, so now this job is so much easier. I think I’m gonna do two coats. Not required in the trimming park, but in the rolling part I’m gonna do two coats. We’ll see how the first coat goes on. We’ll see the uniformity of the paint on the wall, see how that looks. Always do the corners because you can’t get in there with the roller. Always a generous coat. Don’t try to thin it out and stretch the paint because you will see it in the end. Okay, moving around to the other side now. So now you can see that I masked tape all of this. I’m pushing down the bottom part. Make sure the tape is down on the bottom because that’s where we may possibly get some paint on the wall. And because these color are different, I want to make sure that there’s no paint getting on the white walls. These drywalls should be staying the color they are. Always do the trim before you do the rolling. If you do the opposite way you’re gonna see how you trimmed it out when it drys. So don’t roll first until you trim out the area. Okay so you can see I trimmed everything out with the gray paint. I filled my rolling pan with paint. Now we’ll start to roll. When you trim out your walls, there’s no need to wait for this is dry. You can start painting right away. I’ve got a nice coat of paint on here. This will be the first coat, we’re going to see how that applies. If it needs another coat, then we’ll roll on another one. It’s good to go back after you put a bunch of paint on so you don’t get globbing (where the paint globs up on the surface). You know those voids really blend in with this color paint. The whites stick out while the grey kinda hides in there. If you’re doing a corner like this, don’t do it with the metal part because you’ll hit the wall like I just did. So do it in the opposite direction, with the metal part out away from the wall so you don’t hit it. You’ll see the wall that is now finished. It’s got stuff in front of it now. You can see how nice this came out.

  1. I don’t like all the throwing around the products and tools. I know this is a mans man but be a lil more professional damn. Act like you give a damn. 🤦🏽‍♀️

  2. I would use a plastic hanger and a drill to mix the paint more quickly and thoroughly
    Would quickcrete stick in the imperfections of the wall ?
