Nice! One section of mine has a similar pattern to yours. I really like it. I wish my whole floor had it. I figured it was from the concrete curing blankets, but maybe not if yours was done in Texas in the summer. So did you calculate and mix up a little extra u140 on the first coat or just put 1.25 gal each coat?

Thanks
Took just under two gallons the 1 st coat
I started paint the walls today and got a few drops of paint on the floor wiped right off.

I am def going this route in the spring when the temps climb again. It appears the more coats the more shine/gloss you get. Would you concur with that assumption?
Have you guys scratched the floors yet and had to repair ... is it easy to repair and noticeable once dried?

Jumping on the bandwagon here. New home construction, machined troweled garage slab (24x25) is about a year old, never really been used / had a vehicle on it.
Been working on it the last few days. Swept, mopped, shop-vac'd the saw cuts out. Rented a buffer machine yesterday. Today me and one of my sons scrubbed the floor real good. We wet the floor down with water, sprayed Simple Green from a pump sprayer and used a black pad on the buffer. We did one square at a time and made sure to rinse it clean before moving to the next square. Once the whole floor was clean, we did a final rinse and used a floor squeegee to get the bulk of the water out.
I just ordered 2 gallon of the U140 a few min ago. Hope to get it done this week while it's still warm, provided we can dodge the football games enough to spend time on it.

My U140 came today. I've got a new microfiber flat mop and extra head. I'm gonna try to get the first coat on tomorrow evening g and the second coat on the next evening.
When you guys mentioned it worked better wet, how did you wet the mop (spray it, dip in bucket, etc?), and how wet did you get it?
Any other tips you can share?

Im probably a little late, but as I recall I just sprayed it good. I actually had better luck rolling the first coat. Let us know how it went.

I just finished about 2/3 of my basement today. Everything was moved into the other 1/3. The 2/3 was almost 800 feet and was a natural break at one of the control joints. I cleaned the piss out of it with a floor scrubber, brush and green pads, and was hoping to eliminate the brown looking color from the power trowel and get to one even color. That didn't happen. I also have tire marks from my zero turn that would not come up with anything I tried (cleaners, solvents, paint stripper, torch).
First gallon covered the whole area with only about an ounce left, so the 800 sq ft/gallon is good. I used a microfiber T bar from Lowes. There is a lot of drag and work to wet out all of it on the first coat. Second coat, I mixed another gallon. It went on much easier and to spread it thin enough I had about a quart left. I did not do the recommended diluted primer coat but I think that might be a good idea and make the first real coat go on much easier. It has a little gloss to it and looks about like the pictures above. It will be nice not to worry about oil and grease soaking in.
Also, I did the first coat late afternoon yesterday with temps in the upper 60's, but humidity was very low, 27%. It took about 8-9 hours to dry to the touch and not feel at all tacky. I did set a small humidifier near the door and let it run all night, but doubt it helped. Today humidity was about 80% in the morning and about 40% when I put the 2nd coat on. It has been a little over 2 hours and it is nearly dry. Not sure why the 2nd coat dried quicker under similar conditions; maybe soaking in the concrete slows it a little too.
Now.....the other 1/3 after I move everything again.

Glad you posted, reminded me that someone else had mentioned a primer coat and I'd thought about doing that. I mixed up a little at 1:1 with water and did a primer coat. Got done at 6pm EST and just checked it and it's still got a little tack to it on the last square I did. If it dries enough tonight I'll put the 1st coat on, otherwise I may get up and do it before work in the morning.
Pic was taken right after I got done with the primer coat.

Spray then roll
Got up and put a second really thin coat on Friday morning before work. Thinking more about it later in the day, I think I'd put it on too thin. I was more mopping it on rather than just using the mop to just spread it, if that makes sense. It wasn't anywhere near 800sf/gal rate, so really I probably kinda put 2 "primer" coats on, although only the first one was mixed 1:1 with water (which I really think helped the later coats go on easy).
About 8pm that evening I put on a "normal" (?) coat. Spraying a section at a time in a circular motion about 3' wide and the length of the square I was working in, and just using the flat mop to spread over that same area.
I still had enough for another round and figured I may as well use it vs throwing it out, so put on a final coat Saturday night about 11pm. It's dry enough to walk on today and looks real good. In person it is closer to semi-gloss than it is matte. Thought has crossed my mind to try and polish it to a full gloss shine, but I think I'll leave well enough alone at this point and move on to the next item on my To-Do list. I'm happy with how it turned out.
BIG THANKS to all who have posted their experience and tips, it was very helpful and much appreciated.

It looks great. Don't try to polish it though! Coatings cannot be polished like wax. They will degloss and turn hazy.
Thanks Shea, I'll take that advice e and leave it as is.
Figured I’d post an update. I am REALLY happy with this sealer.
As reported by others, I’ve had a few drops of gas, oil from the dirt bikes get on the floor and it just wipes right off. Had some drops of white trim paint get on the floor while painting the baseboards and it too wiped right up with a wet wipe. The floor sweeps very easy as well.
I did notice that pushing my street bike around while on the rear stand left some scuff marks, so I’ll not do that any more. I got a cheap mat from Lowe’s to try out under the dirt bike stands to keep them from scuffing the floor. Looks like they will work good, so I’ll pick up a few more for the rest of the bikes.
At some point I plan to do the entire basement with the U140, but that’s way down the project list right now.

Thought I would give a review since I had a mishap. I was changing the oil in my diesel pickup, it holds about 10 quarts. I put the drain pan under the drain plug, removed the plug, got out from under my truck and went to my house to let it all drain out. When I came back, I had oil everywhere. nasty diesel black oil. I guess it came out faster than it could drain into the pan. I don't know. any how, I threw some stuff like sawdust, forgot the name, the stuff that you put on oil spills, all over it. I talking about 3 or 4 quarts here. Then I ruined my newish broom trying to sweep it up. Oil on my shoes, was not having a good day. I closed the door to the shop, as I was too ticked off to continue. Decided to clean up the next day. So the oil stayed on the floor for about 16 17 hours. I just knew my floor would have a ********* spot on it. The pics are from the next day after I shoveled up the oil soaked material I had put down. There was still a lot of oil there that had not been soaking up in the sawdust like stuff. { can not think of the name of that stuff} Any how, I am sure glad that I put this stuff on my floor. Just though some might like to see. I cleaned it up with dawn and a mop. Then I sprayed brake cleaner on it, wiped it with shop towels. I do not think that I ruined the coating either, nor do I care.

That is not an expansion joint, it is a control joint.

I wanted to share My experience with Covertec U140 in my new barn.
After talking to Charles from Covertec and getting all my ridiculous questions answered, I ordered a sample of CD80 and the U140 to try in a small area to make sure it was what I wanted. My floor is 5 years old and was power troweled to a smooth surface. I did the water test and the concrete darkened in the correct amount of time, but the puddle would take a long time to fully absorb and the next day you could still slightly see the dark spot. When I tried the densifier, it didn’t seem to want to absorb. I talked to Charles again and he said my concrete must be extremely dense or maybe even had some type of sealer or densifier in the mix (I have no idea if it does or not) and to just start with just a primer coat of the U140.
After applying a primer and 2 full coats it in a small section in the closet I decided this was the right product for me. When I was ready, I bought the 4 gallon Semi-Gloss kit to cover my 1728sqft. I was a little worried I would need more but knew I was doing the floor in sections so I figure I could order more if needed.
The barn is taking longer than I would like, so as I mentioned my floor is 5 years old, but I have made sure not to spill much on it other than wood shavings and little paint specs here and there. I started out by mopping and “buffing” the floor to remove any loose surface material. I bought a $100 used 20" 2500rpm burnisher and used Armadillo concrete scrubbing pad #255-2035. The floor was already shinny at an angle, but this really shined it up pretty good.

To Start, I followed all the Covertec instructions to the T and used an automotive paint mixing cup to measure everything out perfectly. I mixed up small amounts did as much as we could them mixed more so I pretty much had no waste.
Primer coat:
I had my wife run the Scotts pump sprayer #190499 with the cone shaped nozzle setting and I worked the $20 Bona mop #WM710013432 & microfiber pad #B07RHLXDZS to apply the primer coat. As others have stated the first coat was a little difficult. Even with the mop pretty wet it wanted to catch and flip instead of glide along. It was 70 degrees out and the coating seemed to **** into the floor fairly quickly, but still remained a little tacky hours later so I let it dry overnight.
The next morning the floor felt a little “rubbery” but was actually dry enough that it didn’t leave fingerprints or sneaker marks at all, so I think it was just me being nervous to do it wrong.

1st Full Coat:
The first full coat went down much smoother. As long as I didn’t try to go back and mop over a section that was done 5 minute prior the mop didn’t stick too bad. I ended up having to let this coat dry overnight as well to get to the point where it wasn’t tacky.

I then left the floor alone for or 3 days before really looking at it. I seemed to have light “mop haze” on the floor if you got at the right angle. Feeling it there was no ridges or anything, it looked more like streaks you get when cleaning things. I was planning on doing a light burnish anyway, so I used a Boardwalk synthetic fiber polisher pad #1861188 and made multiple passes in both directions. Most of my “mop haze” went away and the shine increased a decent amount.

I had too much stuff in there already, so I did half the floor at a time. The second side came out the same as the first. The 4 gallons was plenty in my situation.
The first couple of weeks I was being very careful not to scratch or drip anything on the floor. Initially it seemed to scratch easily. I would get small white scratches here and there from random things. It’s now been 2 months and I recently dragged a floor jack across it with no damage, so I think it just took some time to really harden up. I have since also spilled white vinegar, kerosene, and engine oil on it that just wiped up easily with no staining or change in the surface. Overall I’m thrilled with the product and Covertec as a company. I have yet to begin really working on cars in the barn and I’m sure that I will eventually damage the coating, but I’m hoping to takes a while.

Looks good!
Doing the basement finally bubble to the top of the To Do list. Spent this weekend with 2 floor scrubbers getting the floor clean. Just ordered 4 gal of U140. Will be so nice to not track the concrete dust up the basement stairs.
