In this video we are showing you how we installed a polished concrete overlay on our office floor.
We started the process by grinding the concrete. (not pictured) Once the concrete was clean, we applied 100% solids epoxy to the floor. Then we broadcast sand into the epoxy to give the concrete surface a rough profile.
We mixed the Increte Systems Level top polishable overlay with the Collomix LevMix concrete mixer.

We poured the concrete overlay and then ran a 3/8" guage rake over the floor to apply the material at the correct thickness.
Gauge Rake: amzn.to/2HwnxEX
3/8" Gauge Rake cams: amzn.to/3bLqPSy
Spiked Roller: amzn.to/38GiJsA
We polished the concrete using our Lavina 25" propane grinder.

I just came across this channel...some of the best work I've seen!! Such QUALITY!!

@TimDCVA Год назад

Awesome. Thank you! 🙏🏻

@victorycigarettes 2 года назад

Cool video. This gives me a good idea how strong these polishable overlays are.

@TimDCVA 2 года назад

Thanks! Fwiw- 2 years later & the office floor still looks pretty good.

@dekonfrost7 Год назад

Excellent work. Good synapses

@casade2831 Год назад

Hi Tim, Thank you for helping me answer my questions. I hope others benefit from them as well. Is adding the epoxy and the sand necessary if you have newer concrete with a good grip? What if the concrete has that broom finish already? Do you still need the epoxy and the sand before the self-leveling concrete? Thank you

@KYTechnician 6 месяцев назад

Hey Tim, Love what you did with your floor and the super instructional video! Do you have an epoxy product that you like? About how long did it take you between batches, and did you have any problem with the old batch drying between pours?

@rexmundi8154 Год назад

Thanks for the video. You did a great job of putting it together. How many Sqft per bag?

@csbl63able 4 месяца назад

If you have existing concrete that has some cracks, wll new cracks come through new overlay. Can you put a crack proof membrane under it like floor tile.

@AxelJacquesson 2 года назад

Awesome work!! I was wondering if you could get the same flat visual finish with a stain instead?

@TimDCVA 2 года назад

Thanks! You can get a similar sheen but you wouldn’t be able to get a color this light.

@alanmolina9273 4 года назад

Great work. I've never used increte but I have used Ardex and TRU PC overlays, they advise starting with a 60/80 diamond. But looks good, and I've accidentally overground overlays before lol. It happens. Where are you guys based out of?

@TimDCVA 4 года назад

Thanks! The overlay sat for almost a month before we were able to polish it... so I think it just got really hard. I think 60/80s would have cut it if we didn’t wait so long. We’re in VA.

@supaseb48 2 года назад

Amazing end result! how long did the whole process take?

@TimDCVA 2 года назад

Thanks! Probably 3 full working days. We used this project as filler between other projects so we finished it during downtime over a 3-4 week period.

@ge2719 Год назад

would a finish like this hold up as a gym floor?

@AxelJacquesson 2 года назад

Greta work guys! Do you typically do 3/8 thickness minimum? Do you think 1/4 inch wouldn’t hold up as well?

@TimDCVA 2 года назад

Yes 3/8”. I’d be worried about grinding through 1/4”.

@jackszumski7118 3 года назад

awesome video! The floor came out great! could you also use this epoxy and sand method for an exterior pool surround that is heavily pitted? Would the overlay on top of epoxy hold up in a sunny tropical environment like Florida?

@TimDCVA 3 года назад

Thanks! You could do that... but it’s unnecessary for most overlays. Westcoat, Increte, Elitecrete and many others make overlays that work great in that type of environment without an epoxy primer.

@jandaminer Год назад

Great video! Can this be installed over wood subfloor in new construction? Or would it tend to crack since the subfloor isn't as solid as a concrete slab?

@TimDCVA Год назад

Thanks! I think it would probably crack on a wooden subfloor. I’m not really sure though.

So its 100% Epoxy on the first step? What Brand? What type of sand? For second step? Did you say “Cast sand”? And is it the Euclid Increte Level Top polish?

I love how your floor turned out! What color additive did you use? Thanks!

@TimDCVA 3 года назад

Thanks! We used Sand Buff from Increte.

@lindaweidner5124 3 года назад

Can this be used to cover cracks on a concrete front porch deck that is covered with a roof but is exposed when wind or snow blows? We are getting leakage through cracks through the ceiling of the old “coal cell” room below.

@TimDCVA 3 года назад

This particular product can’t... but we do use a product made by Westcoat that is made for a scenario like the one you described.

@ConcreteBVI 4 года назад

What bond diamonds were you using on your first cut ? Do you think it took so long to cut because you needed a softer bond for this hard polishable overlay ?

@TimDCVA 4 года назад

We were using soft bond. I think it probably took a long time because we waited 2 weeks between pouring and grinding it.

@ConcreteBVI 4 года назад

TimDCVA could also have to do with the segment design. How many segments were they ? 2,7,10?

@overlordfuzz9254 2 года назад

Could this be done without the grinder/polisher on a smaller scale, assuming the same range of grits used? Alternatively, is there a way a homeowner could rent a less professional machine for a more DIY project? Could this be done on top of a plywood or OSB subfloor?

@TimDCVA 2 года назад

I wouldn’t do this over wood. If you want to DIY a similar look, I would just pour self leveling concrete with a clear sealer instead of a polished finish. Polished concrete would be tough as a DIY project because you need so many different grits of diamonds in addition to a machine & vac.

@DapperSurfacesLLCRochester Год назад

Do you guys run your polisher with two resin pads per head? I guess I always thought you needed 3, never tried 2. Is there any benefit vs 3?

@TimDCVA Год назад

Yes we will run 2 resins on some of our smaller machines. It just puts more weight on each resin pad which helps it cut/polish a little better.

@MPaluba 4 года назад

Wish you were in California to do my project for me. I tried to DIY self leveling. I poured and spread the corners with a trowel. Gave my wife a squeege and she overworked it - but it’s my fault for not putting more emphasis on not touching it/never thought it would turn out the way it did. I did the closet exclusively and that’s pretty much perfect. The remaining 350sq ft is uneven, with ridges and high points here and there. Not horrible but certainly not suitable for LVP install. My question to you , if you made it this far, is what should I do next? Buy more bags and pour like I did the closet with minimal movement OR would I be able to grind with a diamond cup or sand it down as you did? I could send a video of what I’ve got in an email to you if you’ve got a minute to help me out. I’d be super grateful. Awesome video

@TimDCVA 4 года назад

Thank you! I think you might be able to grind it smooth...but it depends on the product that you use. Send me an email...I’d be happy to help. My address is in the description of the video.

@MPaluba 4 года назад

TimDCVA hi again Tim. Thanks for the quick reply. I apologize for my delayed one. I used a squeege on my first attempt and a concrete placer (similar to a band trowel). Big mistake. Want to buy a gauge rake and spiked roller. I’ve done a little research on the rakes and see you used a KAM rake. Do you prefer this over the sled? What about a wire gauge rake? Please let me know what specific gauge arise and spiked roller you’re using.

@MPaluba 4 года назад

TimDCVA I just answered my own questions by seeing your description. Still, curious about your rake in gauge rakes. Is cam the best? I thought wire was better. For spiked roller, that’s what I was going to buy. Did see a Kraft tools one that is about 2x more expensive... is there a significant difference in results for a beginner like myself when using the kraft spiked roller? Thanks a lot, in advance

how can you do this and end up with good wet slip performance?

Polished concrete isn’t very slippery... but you could stop at a lower grit if you are worried about it.

Polished concrete is usually less expensive.

@clarkchen7687 2 года назад

Are sawcuts required for the polished concrete overlay?

@TimDCVA 2 года назад

I don’t think so. We do always honor the existing saw cuts and make sure we RE-cut them in the overlay.

If you were walking barefoot in this floor, would you still be grounding? Or is it not a material suitable for barefoot grounding?

@jasonkritz3055 2 года назад

Thanks for the video. I am doing the basement in my 120-yr old house. a 1-inch layer of concrete was poured probably in the 1930s, but it is severly pitted. There is even some dirt exposed. Is there a 1 product solution that I can pour over that would fill in all of the pits and cracks (like a polymer overlay) that I could use. My goal is simply to be able to walk in the basement with socks and not get them dirty. I does not have to be as nice as your office lol

@TimDCVA 2 года назад

I’m not sure what the best thing would be since you said some of the dirt is exposed. I think I would call the local concrete ready mix supplier and ask if they have a mix that would work for your situation. Alternatively I would look into Ardex products if you want an overlay similar to what we use. They have a bunch of options that might work for you.

@casade2831 Год назад

You don't have to polish or grind it, right? Could you just seal it after the overlay has settled and get a shine from a sealer?

@TimDCVA Год назад

Yes but the sealer requires a lot more maintenance than a polished surface.

@jimmiecalvert3572 Год назад

Can you do a acid stain or a epoxy over This Micro concrete overlay

@TimDCVA Год назад

Yes you can.

would use this as a countertop?

I don’t think so. I believe that the maximum thickness that this can be poured is less than 1”

@AG-fj7er 3 года назад

did you pour on the sand? wouldn't it get loose?

@TimDCVA 3 года назад

Yes. We poured it on sand that was embedded in epoxy. We scraped and vacuumed the sand before we poured the overlay.

@armandoquezada6184 2 года назад

What bond on your segments?

@TimDCVA 2 года назад

Soft bond

@AK88. 3 года назад

Confused why you used epoxy only to do concrete why not just make it an epoxy floor?

@TimDCVA 3 года назад

I prefer polished concrete in my office. Epoxy + sand was used to help the overlay to bond and to prevent out gassing in the overlay.

@ExtrovertedCenobite 2 года назад

May work for an office setting but not a commercial heavily used setting.

@TimDCVA 2 года назад

We installed this product 10 years ago in a hallway at a local college and it’s still holding up well.

@allgravy8155 3 года назад

Is this style more cost effective compared to wooden floors or residential carpets?

@TimDCVA 3 года назад

It probably costs more. Usually between $8-$12 per foot, depending on the size and condition of the existing concrete.

@swany65 Год назад

For this process you used here, what would be the total cost per square foot...including labor?

@upsideways Год назад

North of 15$ I’m guessing. The 60lb bags of overlay were 50/60 bucks ea last time I bought some from rapid set.

@upsideways Год назад

Also depends on the size of the slab. One room versus one were house - big difference

@freestylmx311 3 года назад

Had to lol a little about the 60/80 metals not doing jack to first cut the overlay...funny how the manufacturers all claim you can start at a 70 but not once have I ever been able to cut a self leveler (rapid set tru, ardex, latticrete, mapei..I've done several polishable overlay brands) without starting at a 30 metal. 50 grit copper terrazzo pads ran fully wet works though, but the install better be just about perfect flatness...which is hardly ever the case

@TimDCVA 3 года назад

Haha. Part of our problem was that we waited a month to polish it. I think it would have been easier to cut if we had started grinding on it the day after we poured it.

@allanread911 2 года назад

Are you talking about polishing just normal flood coat say mapei or Ardex ? I’m just looking into all this overlay stuff and thinking maybe polish prep it’s hard enough. Check out aqua zeros by worx I rate them . I use them on bernished concrete love them
