Floor Epoxy

What kind of activities are you planning to do in your shop?

That sure looks nice skegpro. Post another picture in a year or two, just want to see how it stands up.

I just took this.
10 months of use later.

The nice thing about epoxy is you can fix it.
I sanded with 400 grit in between each layer, it looked like dog****. But when you put the next layer on it looks awesome.

So in 5-10 years I can touch it up no problem.

This is in my attached garage, in my farm's work shop I did polished concrete which gives the same type of finish but still maintains the toughness of cement. But polished is more $$$.

Gun picture is from today.

Radios is from 3 months after the floor was finished.

Skidoo panel plug is from the polished concrete in my work shop.

And the sander is an intermediate step.

Im doing a barn reno for air BnB rental. I'd luv to do the floor like you guys did, but how slippery is it? Snowy boots concern me.

It's about the same as power troweled concrete and you could always mix silica in the last coat to give it grip.

Here was my floor after cutting.

Here's after the epoxy.

Wow what did you used to cut the cement if it was that hard?

Diamond toothed flail head cutter. Would cut 9" strips per pass. Did entire floor in about 3 hours, worked really well, but noiser than eff, and a lot of dust. Tried cutting with a bit of water but didn't seem to make much difference except for a big mess for some reason.

We've used similar at my employer. Funny how the norm of concrete strengths has changed as of late - majority of our large projects are now pouring 70-80 MPa (10,000psi+) crete

Looks great Geoff. Is the increase in MPa related to the deterioration by all the salt? Does a higher MPa make the concrete stronger and less spalling. The old concrete berms and bridge edges sure take a beating with all the salt they use.

Most projects seem to be trying to reduce costs in using smaller volumes of concrete by going to higher strengths. It doesn't sound like a big deal, but thinner concrete walls result in smaller excavation diameters, reducing the cost. Majority of our installations the concrete isn't solely in a state of compression, but also sees some lateral bending loads. Concrete is typically poor in bending. Thus, in the high strength range we are using quite a bit of steel or compositve fibres for mix reinforcement. To add to the challenge of working with concrete in this strength, we are either pumping it, dropping it large distances, or having to truck it in some cases for close to an hour before it's unloaded. Some of the mixtures I've seen lately are very unconventional to account for all of this. Salt is an issue with concrete, but really any of the chloride resistant products do what we need it to do. Some of the rehab work we've completed over the past years are on concrete that has been in place since the 60's in a very salty environment. Concrete in those years was nothing special (sulfide resistant wasn't readily availble at that time) and it made it 40-50 years before failing with likely non existent quality control.
