If you have a concrete basement or garage floor that you want to remove paint from, you'll want to watch this video.
Someone painted the concrete floor in our basement many years ago (the house is around 60 years old). We had no idea what type of paint (water or oil based) it was, and a lot of it had already chipped off, or was worn away. We originally thought about just leaving it and covering the floor with laminate tile, but we found out that we had slight moisture issue. If something with a rubber or plastic backing was left on the floor for an extended period of time (weeks/months), the area under it would darken up from moisture buildup. A local concrete supply company recommended we strip and stain the floor, so that's what we did. Little did I know how much of a pain it would be to remove the paint. I thought I could simply scrape it off, but I quickly found that would have taken days, and my arms may have literally fallen off by the end of it. I didn't want to use chemical strippers as I didn't want those fumes in the house. I tried an orange stripper, but that just seemed to make it harder to remove the paint. Local rental stores recommended floor grinders, but they would remove around 1/8" of concrete, and they also could only get within a few inches of a wall, so that wasn't going to work. I also tried a floor buffer with a course buffing disc, but that did next to nothing. I finally found a floor sander with diamond blade at Home Depot and this thing did the trick. It did take several hours to do around 1000 sq ft of space, but it worked really well. I would highly recommend using this machine to strip paint or mastic off of a concrete floor.
After sanding and cleaning, I stained the floor with a water-based Artesian stain from Brickform (www.brickform..... An acid-based stain is recommended for new concrete, but old concrete has a different Ph level, so water-based stain is recommended for it. Water-based stains are a little more forgiving as well. If you spray it and decide you don't necessarily like it, you can wipe it off with a wet rag (if it hasn't completely dried yet) and start over. If it did already dry, you can still remove it, but you may need to use something more aggressive such as Xylene. Just check out the directions on whatever stain you purchase to see what it recommends.
Once stained, you'll want to seal the floor. I used a semi-gloss seal as I didn't want the floor to have too much of a shine. I applied two coats of seal with a roller. Brickform recommended spraying the seal on, but my sprayers didn't seem to give an even coat, so I rolled it.

So happy I stumbled upon this video! I was actually going to rent one to use on a client's concrete porch. Since he said there was only one coat of paint on it, I decided to use a high quality stripper, cover with plastic and let it sit for awhile before scraping. Needless to say, i have ended up using every method you have at this point and have only uncovered about 3 feet of concrete! There are actually 2 more layers of paint and leftover glue from tile they pulled up. 😮 You have just convinced me that I'll be renting that sander tomorrow. Thanks to you and your son for an awesome video!
Glad we could help! Yeah, we were as frustrated as you, so we thought others would appreciate seeing what we went through so they could avoid some of the same steps. Good luck!
I stain floors and this looks great. the design language of stain is to show the flaws beneath the surface of the concrete for a bit of unpredictable multicolored drama. I tell my clients that if they cant handle that, lets just paint the floor a solid color with high filler floor paint. I honestly try to talk them out of acid staining and make sure both homeowners are there to understand that. very nice job on the prep, I never wet sanded like that before and a nice job of spraying the semi transparent stain colors. congrats!
Thanks Paul. It was a lot of work, but well worth it. And the kids enjoyed transforming the room.
Acid stain can produce a beautiful floor AS LONG AS THE CONCRETE HAS A HIGH AMOUNT OF FREE LIME so the acid stain can react.
Cat came in at the right moment lol!! Stole the show…
Thanks! I feel comfortable doing this. I actually have a few layers of paint, flaking up. I’m painting over again.
Awesome work! I'm doing my porch and this has been so helpful.
Thank you and your protégé for the info. I’m ready to do my laundromat floor. And this video with Chevy helpful thank you especially with the splatter proof Velcro strap. 💪🏼🤙🏼🤜🏼🤛🏼

Very helpful tips. Thank you!
Great video - thanks for sharing

Looks decent.... im trying to decide between stain & wax or epoxy with flakes , then a coat of polyaspartic
Thanks
I am going to apply epoxy coat after removing the paint off from my garage floor. Should I apply a moisture sealer before applying epoxy?
I would read the directions on the specific epoxy that you're going to use to see what it recommends.
Prep a 1 foot square of the concrete and tape plastic over it. Remove in 3 days to see if any moisture has collected under the plastic. If not, coat away !
You mentioned the rental cost but what was the final price for everything including the spray bottles and staining?
All in, I probably have about $500 into the floor.
Can we watch?
Was a good video just next time show the paint material how to apply it …you give good information …thank you
Will this etch the concrete sufficiently to allow for painting?
It opens the pours enough for staining, so it should work for painting as well.
What did you use for along the walls?
We tried several things, and we ended up using a pneumatic scraper since the paint was fairly thick along the edges.
Thanks! I have a similar project but have been putting it off cause I wasn’t sure how to prep the floor/scrape the old paint and adhesive off/etc.
O you need a truck to trNsport?
You would have had better results and saved a little time going side to side instead of back and forth
All that work to make it look dirty at the end? Huh
