Patio Cement Repainting

I have a patio with cement floor, about 10x20 ft.

I've painted it a few times over the years using cement paint from Lowe's. Problem is, they keep peeling in spots and scraping those parts off to repaint is impossible it seems. Any suggestions on doing this so it lasts longer than a month?

Same thing is happening in my front door steps.

Thanks for the tips

The main reason paint fails on a concrete slab is moisture migrating up thru the slab lifting the paint.
I assume you've been scraping off all loose paint prior to repainting. While you will find a better grade of coatings at your local paint store [versus any paint dept] I don't know that would fix the issue. I prefer to use a solid concrete stain over paint as it's less likely to peel.

Anyone know how I can completely remove the paint? I mean it's about 10x20 so it'll probably take forever. Is there some sort of machine I can rent, some heavy duty scraper or paint remover?

I'd use paint and varnish remover followed by pressure washing - the pressure washer mainly just makes the job easier.

I'm a novice, but I'll tell you my stories:

I've got Dyco Pool Deck paint and it's going strong after a year. I painted two coats, with nonskid, over BADLY flaking paint from the previous owner. I did hand scrub every square inch before painting. However, it's probably not any better than the Lowes brand. Scooting chairs and furniture, anything hard, possibly hard high healed stripper shoes, scrapes the Dyco paint right off. But it is not peeling or flaking. I can walk on it with my work boots and bare feet not have flakes of paint on my feet. That's really the only thing it solved.

I used Lowes (Valspar) Solid Concrete Stain on my driveway. It looks great. So far it's not coming up with the car tires (like a regular latex would). But that stuff ONLY works on porous concrete, meaning you'd need to power wash all paint off your concrete and possibly acid wash it. Otherwise it's just another latex coating, and it's a flaky one at that. It's not a nice skin like the patio paint. I hope it lasts 5 years and another coat will take without flaking off.

The 2 options I've not tried yet are professional staining and two part epoxy. Both of these options are expensive and require more work to apply. My guess is it's what most garage floors are. But you are approaching the same price as new pavers and tile which would be so much better. I'd only do these coatings for a garage floor that cannot accept thin tile.
