KILZ 1-Part Epoxy Acrylic Concrete and Garage Floor Paint, Interior/Exterior, Satin, Slate Gray, 1 Gallon

Read a lot of reviews on a lot of different concrete paints before settling on this Kilz paint for the interior floor of a 40x100 workshop and the external concrete pads which are 30x25 each.Prepping the concrete is easy but time consuming for such a large area. I did the interior shop in 40x25 sections, so obviously had to clear out the section to be cleaned and and then pressure washed the cement with a 4000 psi pressure washer and plain old water. It was taking forever with the standard wand, so wound up buying one of the rolling cleaner attachments that has spinning nozzles underneath and keeps the nozzles a consistent height above the floor. That really sped things up. Pressure washed it all twice, making sure to flush out the dirty water with clean after each wash. Let it dry completely (not hard in Texas...one full day was sufficient) and then use a drill-attachment to mix the can of paint thoroughly top to bottom. Used standard paint roller and tray and did my best to apply thin coats like the instructions say, overlapping and cross-hatching it to ensure I was getting total and even coverage. let it dry as per instructions, then did a whole second coat in the same way, thin and cross-hatching.The instructions say to let it cure for a week (if I recall correctly) before putting heavy traffic on it. In my case it had more like a month to cure because I had to travel for work. It's also relevant that this was inside a metal building in Texas summer. The smell was really not bad at all, though I did keep the doors rolled up so cross breeze could help.The outside cement pads I cleaned the same way (double pressure washing) and painted the same way. This was harder because the paint wanted to dry REALLY fast, so had to take smaller sections and roll quickly to spread it evenly and not be too heavy. Inbetween first and second coats my dog decided he would wander across and check things out, so after the first coat dried I pressure washed the muddy footprints and hoped it wouldn't peel up the new paint. Thankfully, the paint stayed in place. Put down the second coat and that was when I had to leave for a month, so the outside cement didn't get much traffic either; just dog and cats and whatever other creatures walked over it.Two years later:The inside floors are doing well. Unfortunately it is just paint so when you drag something across it like car parts or jacks with metal wheels, it will scuff the paint and sometimes scratch through it. That said, it's holding up very well. There are two small spots where it's peeled and I assume I just didn't get the floor as clean as it needed to be or perhaps had the paint too thick. One spot is about 4" across, the other is about the size of a quarter. My goal was to prevent oil staining the concrete as I rebuild old vehicles and I hate having a mess. In regard to that goal, the paint has been very successful. It prevents oil or coolant from soaking in and wipes up cleanly.Outdoors the paint has faded noticeably after two years in the sun. It still looks good from a distance and still keeps oil from staining the cement, but it needs to be redone. I also pressure wash vehicles outside on the pads so the paint gets hit with high pressure water pretty regularly.ZERO issue with hot tires peeling up the paint.Very minor issues with paint not adhering to the concrete, but since 99.5% is so good I have to assume I did an inadequate job of cleaning in those spots; can't blame the paint for that.I'd absolutely recommend it and I've bought more so I can re-wash and re-paint the outside pads. However, just like any paint job, if you aren't willing to put in the effort to make the surface clean and ready then you won't get good results. That's not the paint, that's you.

Bought this to cover up a stained, unsightly porch on our new house. Prepped the surface with Zep Driveway & Concrete Cleaner, allowed to dry, and painted right after. Only one coat (~half the can) was used, and I'm completely blown away by the results. I used the Silver Gray color. Hopefully it holds up well over time in the muggy Florida weather!

Gray but not the gray in the pictures. It was a blueish gray. It looks like it doesn’t level out but it does just very slowly. I put gray over red (concrete) and will need a second coat. I used a paint stripper (three coats) and sanded and still think I could have prepped better. The paint shows a lot. I don’t know that that’s the paints fault, maybe that’s a concrete thing.

Nice product

I painted my concrete basement floors about three months ago with this and it’s holding up fantastic even with heavy traffic (4 dogs).

Did 2 coats in our garage and left sit with no traffic for 2 weeks. Pulled the cars in the garage last night and when we backed out today, the paint is already peeling up where the tires were. Complete waste of time and money.

Goes on fine but needs a second coat

Good paint, used a few coats for the laundry room concrete floor. Holding up well
