Sealing The Deal

UPDATE: We shared how the counters are holding up here for ya!

Thanks for all the kind words on Teddy’s arrival last week. We’re home now and settling into life as parents to a newborn again (anyone have tips for getting one to sleep between the hours of 10pm and 4am?), so we’ll definitely be on a lighter schedule, but one project that we rushed to check off the to-do list around 48 hours before Teddy was born was finally sealing our kitchen’s recently Ardexed counters.

We’ve shared a few other “how to seal” tutorials (like this one about de-hazing & sealing tile, this one about sealing grout, and this one about sealing cork) so here’s what we settled on for protecting our Ardex counters.

We read a bunch of the-sealing-step-could-make-or-break-them posts when it comes to Adrex, so we resisted the urge to rush into anything, and we used some of your input on our March 24th post to help select which sealers to research a little more and eventually track down (we had to order one from Amazon). In the end, our method of choice was two coats of 511 Impregnator Sealer (found on amazon) followed by three coats of Safecoat Acrylacq (which we already hand on hand, but can be ordered online as well). The great thing about using Safecoat as a top-coat in a kitchen environment is that it’s non-toxic and 100% food-safe.

The Impregnator’s job was to seal the concrete – against staining and moisture absorption – and it was very easy to apply. The water-like consistency made it easy to spread, so I poured a bit in a bowl and then brushed it onto the clean concrete surface liberally.

The instructions say to wipe off any excess after a few minutes, but I found most of mine absorbed into the concrete pretty quickly. But as a shameless rule follower, I wiped nonetheless. It looks darker and splotchier than it did after it dried in this picture (since it was mid application) but after it all soaked in it was pretty much back to its original color.

We applied that twice (24 hours apart) and then gave that last coat 24 hours to cure before moving onto the last step, which was top-sealing with the Acrylacq. This would also seal the counter against stains and moisture (liquid would bead up on the surface instead of absorbing and making rings) as well as creating a nice polished look that’s both food safe and protective against chipping or scratching. I went rogue with this stuff and just poured a small puddle onto the surface and spread that thinly across the counters with a brush.

We use Acrylacq a lot, so we’re familiar with it (I’m no longer alarmed by the blue-ish tint that it puts on the surface while it’s still wet).

We applied a second and then a third coat of the Acrylacq, just to be safe (letting it dry about 12 hours between each one). Then we let it cure for three full days before putting anything on it, even though it was dry to the touch much sooner than that. Although the Acrylacq was just a “satin” finish, it made the surface significantly glossier than the chalky finish the original Ardex had left. I realize that sounds like I was disappointed, but it’s great.

Not only does the glossier finish make it feel more like a shiny stone countertop (and less like a chalky DIY job) it also protects the counters much more from spills/stains. No longer do drips leave longstanding discolorations on the surface (picture water soaking into a concrete walkway outside and looking dark for hours). Now spills and splatters just bead up and can be wiped away without any trace.

We also read that some sealers show a lot of scratches, but so far we haven’t had any show up, even after cooking some big family meals and sliding some heavy dishes around to serve things. So it seems as if this mix of sealers yields a nice stone-like look that’s food-safe, scratch-resistant, and makes liquids bead up instead penetrating – at least so far.

My only complaint about our sealing results is that the glossier finish makes it slightly easier to see imperfections in the counter’s surface, namely areas where I should’ve sanded things a bit smoother during the Ardex application step (just like how glossy paint will accentuate imperfections in walls, this follows the same principle). Sherry is quicker to embrace these imperfections as par for the concrete counter course (“they’re supposed to look like that”) but the perfectionist in me just sees areas that I could have smoothed out a little more before sealing. Either way we’re both ecstatic to finally have everything back on our counters and be able to use our kitchen again like normal people. And it’s definitely a huge step up from the old yellow laminate that we had before.

Note: There have been people who’ve asked if we’d like to paint those bottom cabinets now that the counters are done, which is always a possibility, but for now we’re a lot more distracted by things like that faux brick linoleum flooring – so that’s at the top of our list.

There are still some things I’d like to improve about my Ardex-ing technique (namely sanding more smoothly) but generally I’m really happy with how it all turned out. Especially how the sealing step turned it into a much more finished feeling surface.

Aside from a few the-family-is-in-town-to-meet-a-new-baby meals, we haven’t used the kitchen like crazy yet, so we’ll definitely keep you posted on how it wears. Whether stains get through and we get scratches galore, or things stay pretty darn similar to how they look now, we’ll definitely share some updated detail shots in a few months time.

Has anyone else used the same mix of sealers? Or had good (or bad) luck with another combo? Feel free to share those details here for anyone who might be tackling this soon. In the meantime, I’ll leave you with a photo comparison that a bunch of you guys have requested. Here’s Teddy at four days old:

And here’s Clara’s when she was around three weeks old in the same pose. They seem to have identical (extra long) fingers and toes, the same invisible blonde eyebrows, and the same tiny little chin – but Clara had a lot less hair. This Clara picture and this Teddy picture are probably the closest comparison so far (in real life we think they look related – but not quite like twins).

Now about those tips for getting a newborn to sleep between the hours of 10pm and 4am. We’re all ears…

Trying Our Hand At Ardex Concrete Counters

So we did it. We concrete’d our kitchen’s laminate counters. Sherry shared this quick peek at our first coat in Friday’s post, and we’re back with the final results, the details of how we got there, and an in-action video to hopefully help explain the process.

We’re really happy with how they turned out. Pictures don’t do it justice, but the whole room feels a lot more updated and less laminate-y. It’s giving off kind of a stark/cold vibe in these photos, but after we add some colorful window treatments, stuff on the shelves/counters, and remedy that bad faux brick flooring (and that almond stove) we think it’ll feel like a whole new room. I’m not going to sugar coat it, though. It was a lot of work. And a lot of dust.

Here’s a reminder of what the counters looked like before. We had creamy-yellow laminate (with the occasional burn mark or scratch). In addition to the main kitchen area, we also gave the concrete treatment to the nearby nook by the eat-in part of the kitchen. We haven’t sealed the counters yet (we haven’t been able to track down either of the two products that our research points to using), so the color will probably get a bit deeper after that step.

We did this using Ardex Feather Finish, which we’ve been really interested in trying since seeing a few other attempts like these from Kara Paslay, Little Green Notebook, Sarah’s Big Idea, and A Beautiful Mess. Somewhere between all of their pretty pictures and the low price tag for Ardex ($19 per bag) I had assumed this would be a quick and easy task. Oh silly me…

Maybe it was because we’re first timers, or maybe it was because our work area was especially large (we were dealing with 45 square feet of counters thanks to the U-shaped area in the cooking zone and the nook area by the table), but it turned out to be a tiring and messy job that spanned across five days. It wasn’t very complicated or difficult, just more labor and time intensive than we realized we were getting ourselves into. So let’s dive into the process. Forgive our photos for not being chronological. We took a bunch throughout our four rounds of applying/sanding the Ardex and I’m just using the ones that are most helpful. Let’s begin with supplies!

  1. Ardex Feather Finish, obviously. It’s not easy to come by, but you can hunt for a local distributor on their site or just Amazon it. Richmonders, we found ours at Fishman Flooring Solutions. We ended up using 2.5 bags, though I think we applied it a bit thicker than necessary.
  2. Mixing buckets: We used one of these small red buckets for mixing our Ardex (it mixes with water). We made pretty small batches, so this was a great size.
  3. Measuring buckets: We used these (one for water, one for Ardex powder) to make sure we were mixing the right ratio in our red bucket.
  4. Sandpaper: A variety of grits – both high and low, as well as a sanding block for easy gripping. We used mostly 60, 120, and 220 grit.
  5. Spreading tools: We used the flat trowel (on right) for mixing in the bucket, then used the other three for spreading. The big 10″ drywall knife was good for big flat areas, the 4″ putty knife was great for backsplash and edges, while the small guy helped us get into tight spots, like around the sink.
  6. Stuff for keeping walls clean: We kept a sponge and paper towels on hand to clean up any drips or splatters on the wall. We also taped off some areas too (more on that later).
  7. Protective gear: During the sanding process the glasses and dust mask helped keep stuff out of our faces (Sherry preferred our heavy duty respirator) while the gloves were great for keeping our fingers from getting crazy raw.

Speaking of sanding… the first step was to rough up the existing counters with some high grit sandpaper. This was before we realized our fingers would be taking a beating from all of the sandpaper gripping. We wised up and added gloves and used nice big sanding blocks wrapped in high grit paper about ten minutes into it. It went much easier after that.

The Ardex bag suggests a mixture of 2-parts powder to 1-part water, but we found that balance to be a little bit on the thick side – making it hard to spread and what we believe led to our first layer being, well, on the thick side too. So we erred on the side of a bit more water from that point on.

Like grout or thinset, the goal seems to be a toothpaste-like consistency. Thick enough that it doesn’t run or drip off your blade, but thin enough to spread easily. If you’re mixing larger batches it suggests a paddle mixer, but we did just fine by hand (Sherry took a turn mixing things too and didn’t have any issues doing it by hand). Since it starts to harden within about 15-20 minutes, we never wanted to mix up too much at once anyway.

Spreading it on the flat surfaces was kinda fun, in a weird way. It was like icing a giant cake and using a big 10″ blade made it pretty fast to get the big areas covered. The backsplash was another story, but we’ll get to that in a second.

Here’s a quick video Sherry took of me applying the third coat, since we thought it’d helpful for you to see the stuff in action. I’m not claiming my technique to be great or anything, but we did find we got a bit better each round (Sherry also thought we got better at sanding/smoothing each layer as we went). Which is good news because your first couple of layers will get covered up anyways – so they’re kind of like low-risk practice rounds.

When it came to doing the sides, we switched to a smaller putty knife. We usually did these after we had applied most of our mixture to the top, that way what was left in the bucket had set a bit more and was less likely to slide off the vertical surface.

At first we found the edges to be challenging since it was easy for stuff to build up there. What we realized a couple of rounds in was that after about 20 minutes the Ardex had hardened to an almost clay-like consistency, and Sherry or I could come back and smooth the edges with a damp finger. My favorite part was sneaking up behind Sherry all Ghost-style to smooth them from behind her back. Who says there’s no romance in DIY?

Here’s our first round after it dried. You can see Sherry taped off the wall to protect it when I lamented how much was getting on them as I went. In hindsight we’re still unsure whether that ended up being a smart decision. It certainly made us less paranoid about being messy as we went, but removal was a bit of a pain and not perfect since we were essentially concrete-ing the tape to the wall in a few spots.

We decided to ditch the tape after our second round of counter smoothing, so we slowly worked our way around the room peeling it off (we feared that too much concrete build-up would trap the tape in place forever). One thing that we found during this process was that pulling it down from the top (rather than ripping it to the side like we do after painting) did a better job of getting a clean edge and not just tearing the tape. But we did have to chisel it free in a few areas… so I’m not sure if it was a time saver in the end.

Things looked pretty rough after our first round (well, after every round actually). But that’s where the fun mess begins: the sanding step. Here’s where you smooth out any rough spots or ridges so that the next layer can go on evenly and ultimately get you to a flat, smooth finish.

After letting the surface dry overnight, first Sherry would go across the top with a putty knife and scrape off any obvious ridges that were left by the drywall knife during the Ardex application. Even though it had hardened, it wasn’t tough to do. Blobs and ridges just popped right off as she scraped back and forth over them.

The most satisfying thing was cleaning off the bottom edge. Sherry realized we could just run our smaller putty knife along those and sheer off any irregularities, which left us with an awesomely crisp line on the bottom. Best part of this project by far. Could’ve done it all day.

That step was quickly followed by our least favorite part: sanding, sanding, and more sanding. We chose to do it all by hand, since we feared that our power sander would just sand everything down to the laminate again (or leave rough ridges or marks as it traveled around the counter). Plus, with all of the tight spots like the backsplash and around the sink, we figured it would be easier to maneuver by hand.

We used a sanding block (for easy grip) wrapped in fresh sandpaper each time. For sanding every layer except for the last one we used a really rough 60-grit paper to make smoothing ridges and rough spots easy, but after the last coat of Ardex (we did four coats) was all smoothed on and dry, we switched to 220-grit paper to make sure we didn’t leave big/rough scratches in that top coat of concrete.

Sherry also realized that it was helpful for us to pause while sanding each section to vacuum off the excess dust as we went (thanks shop vac!). This was especially helpful because sometimes the dust would disguise an area that needed a bit more sanding. Plus, it just helped for sanity reasons, since we felt like we were keeping the mess more contained that way.

Speaking of which, the mess was the biggest surprise to us. Despite reading other people’s experiences with it (and obviously, we knew sanding was involved), I don’t think either of us had mentally prepared for the fact that there’d be a fine gray build-up of powder EVERYWHERE. And since the kitchen is such a central and highly traffic area of our house, keeping it clean ended up being a big time suck (after each round we would sweep, then vacuum, and then mop the floors to be sure nobody tracked anything throughout the house when they passed through over the five days that we worked on it).

After our first coat, we noticed the laminate was peeking through in a few spots after our initial sanding step – mostly on edges where it’s really easy to scrape everything off if you’re not careful. But that’s one reason you do multiple coats, so we weren’t too panicked.

Here you can see a second coat beginning to get applied over the first. Note the difference in color between the wet Ardex vs. the lighter stuff (that’s how it dries). We actually think once we seal it, it’ll get closer to the wet color though, so that should be interesting to see.

Here’s a shot of our final counters (well, pre-sealing). You can see it’s still not perfect, which everyone notes is one of the charms of this Ardex technique. You definitely get that sort of imperfect, industrial look. But it definitely feels more solid & stone-like, as opposed to plastic-y like laminate.

I’ll admit that I had to come around to the idea of appreciating the flaws of the finish. Sherry was immediately charmed by it, but the perfectionist in me resented the fact that this type of project doesn’t yield perfectly uniform results. I think once we seal it I’ll appreciate it even more (that will darken it a little and remove the chalky finish in favor of a more polished look) so I’m really looking forward to that.

By far the hardest area to get smooth was the backsplash, just because it was a small area that was difficult to reach and seemingly made up entirely of edges and corners. So both applying the Ardex and sanding it was challenging and required a bit of body contorting on my part (lucky Sherry was too pregnant to reach it in most areas thanks to her belly being in the way, which had me slightly envious by the end of this process).

Another tough spot was around the sink. If this were our “forever” counter, I would’ve gone through the trouble of removing the sink, but we’ve got some old copper pipes that are pretty much corroded together down there (which would mean bringing in a plumber to switch this out). So we opted to save that for Phase 2 of our kitchen update and just taped / sanded around it. The results were actually better than I expected.

Challenges and flaws aside, we’re happy with the overall improvement to the space. It feels good to rid the kitchen of another old yellowed surface and make the room feel a bit more 2014. Just cover the floor with your hand and squint – ok?

And although the time that we spent on this update was longer than we envisioned (probably around 15 hours spread across five days, including prep and clean-up) the cost was still pretty fantastic. The three bags of Ardex (again, we only needed 2.5 to do four coats) cost $57 in total – and we probably spent another $20 in buckets and sandpaper. So for 45 square feet of countertops, we paid just $1.71 per square foot to update it – which is pretty hard to beat.

That doesn’t include the sealer though, which is next on our list. We’ve read a ton of sealer reviews since it seems that the wrong sealer can cause more scratches, stains, and even issues like bubbling down the line – so we want to get it right. The two most highly recommended products seem to be Ardex Clear Concrete Guard High Performance Sealer and GST International Satin Seal Water Based Acrylic Sealer. Does anyone out there have a preference between the two? We can’t find either of them locally so we’re going to have to order one of them online and wait for it to come, but we’ll definitely share what we end up going with, how it goes on, and what it does to change this finish – as well as updating you guys on how these counters end up wearing for us over time.

Have any of you tried Ardex? What’s your take? As tired as we are from all of that sanding, we’re kinda excited to take it for a spin again… just on something much, much smaller.
