Yesterday was an exciting day. Work finally got underway on refinishing the concrete countertops in my kitchen! Just to be clear, these are solid poured-in-place concrete countertops. These aren’t the kind of “concrete countertops” that are a thin concrete product troweled over plywood or laminate countertops.
If you’re new around here, or missed my previous posts about my countertops, here’s the quick rundown.
I have concrete countertops that my brother and I poured in 2014. I wanted bright white, but they turned out more of an antique white/taupe color. Then I proceeded to use a concrete sealer that didn’t really work well.
So now, in 2017, I have dull, dingy countertops covered with stains. I’ve researched many different ways to refinish them, and finally decided on a polyurea coating that’s generally used on concrete floors, like garage floors. There’s only one company in town that uses this product, and they were willing to help me fix my countertops. And now you’re up to speed. 🙂
My brother came over yesterday morning to help me remove my cast iron sink. It was quite a chore. The sink itself weighs about 120 pounds, and it was pretty well sealed to the countertop by a thick layer of caulk. No matter how much I tried getting a razor blade between the lip of the sink and the countertop to cut away that layer of caulk, I just couldn’t get enough of it away to break the seal.
So my brother said, “You might have to leg press that sink to get it out.” 😀 It really seemed like the only way. So I lay down on my back perpendicular to the cabinets with my legs inside the cabinet and my feet firmly planted on the bottom right side of the sink, and then I pushed with all of my might.
My first try was a bust, as I just slid across the very smooth, newly-polyurethaned floor. On the second try, I held myself in place (I think I grabbed onto the cabinets with my hands to hold myself in place) and pushed up again with my feet against the bottom of the sink. After about 15 seconds of pushing with all of my strength, the seal finally broke and the sink lifted up. We were then able to lift that heavy sink up and out of the countertop.
Anyway, the guys got here about noon yesterday to start on the countertops. I posted a few videos on my Instagram stories (you can click here to follow me on Instagram), so you have about three more hours if you want to click over and see those before they disappear.
I tried to get some quick pictures of the countertops before they started, and then during the process, but my camera was having a hard time (not sure what the issue was) and I was trying to hurry so that I wouldn’t be in their way and cause them any delays. But here’s a look at the discolored, stained countertops before they got started…
This picture is interesting. Look at the strip that was covered by the lip of the sink. These counteretops were so much lighter and brighter when they were new!
They’re not just darker now because they’re stained, because other than the areas that are obviously stained, the countertops are a consistent antique white/taupe color, even in areas where the countertop rarely gets used. It’s almost like the sealer I used (or the top layer of the concrete itself) got darker as it got older, kind of like oil-based products yellow over time.
But they were definitely much lighter in color when they were newly poured in 2014.
This area to the left of the stove was the absolute worst. It was the first countertop we poured, and we had no idea what we were doing or what to expect, so it turned out the roughest. Having a rough concrete countertop full of pits and divots right next the stove, and right next to the burner I used the most, is a terrible combination. This became impossible to clean.
The first thing they did was grind the top of the countertops. The grinder looked like an oversized rotary sander, but instead of a sanding disc made of paper, it had a rough metal attachment on it. It was connected to a big vacuum that stood about four feet tall that sucked up most of the dust.
The countertops looks a thousand times better just after the the top layer of discoloration, stains, and unevenness were ground off.
I’ll admit that I was very tempted to tell them to just put a clear coat over this and be done with it. Very tempted. I mean, it looked a thousand percent better by this point. There were very few stains still visible, and the countertop was basically back to its original color.
But I resisted that temptation. While they were lighter, they still looked like a dingy antique white. That’s not what I want. I want light, bright and white, and I would have been very disappointed had I settled for antique white.
Next they mixed up some very stinky light gray primer. They used chip brushes to cut in and brush the ogee edges, and rolled the large areas.
And here’s how everything looked right after the primer was applied…
The primer is very interesting stuff, and I kind of have mixed feelings about it. It was very thick, started to set up in about 15 minutes, and then was incredibly sticky. He told me it would dry in about two hours, and as it dries, tiny little bubbles would form on the surface. Once it stopped feeling sticky, I could sand it and then paint it.
Well, it took about five hours for it to stop feeling sticky. I expected the shine to go away at least some as it dried, but it didn’t. When it was dry, it was just as shiny as it was when it was first applied and very wet.
Here’s how it looked last night at about 10:00.
The primer feels like a soft plastic, so sanding it is very strange. And in fact, it’s very difficult to sand.
I do understand that it’s a special kind of primer, and so it being thick, super sticky, and feeling like soft plastic is actually a good thing. Concrete naturally expands, contracts, and sometimes cracks. This product is made to be strong yet flexible to cover and prevent cracks. I get it.
But in hingsight, I almost wish I had just had them grind/sand the countertops, and then let me use my go-to oil-based primer on them instead. After the sanding and grinding, the concrete was so unbelievably porous that I have no doubt my favorite primer would have stuck to it very well, and it would have been sooooo much easier to sand.
But it’s too late for that now. 🙂 It looks like I’ll be spending my morning sanding plastic. Hopefully by noon, I can get to the fun stuff — adding a painted marble effect to these countertops.
I told him I was nervous about the painting process because I just wasn’t sure if I could get it to look right. He assured me there was no risk because if I paint it on and don’t like it, I can just stand it off and start over again. I can do that as many times as needed until I’m satisfied with the look.
Ummmm…that was probably the wrong thing to say to the queen of do-overs. I might be stuck on this project for a month. 😀
After I get the design painted on, they’ll come back and do the most important step — the clear coat of polyurea. Hopefully that can be done late today or even tomorrow so that I can get my kitchen back in working order. I’ll show my progress on my Instagram stories if you want to follow along there. If not, you’ll have to wait until next week to see how this project turns out. 🙂
Well, I’m off to sand some plastic. This should be interesting.
