Discolored concrete patio
 
2 Attachment(s)
The previous owner left white paint spots all over the concrete porch and as you can tell the concrete is getting very discolored from over the years. I used my pressure washer yesterday, but that didn't do much. What's my best approach to make this area look better?

The paint drips will likely need to be scraped by hand. I would suggest a much more powerful pressure washer for the balance, along with a cleaner like bleach or any of the commercial cleaners available.

The paint drips are 7-8 yrs old though. Can't do it.

Sorry I guess I can't help you then, as I have no idea what this word means. I was brought up by a Father who told me that word didn't exist and should simply be replaced with "I don't want to because I'm too lazy"......

Try harder and scrape the paint off........

Sorry I should have said the 10 attempts I have made to scrape it off have proven to be unsuccessful.

what about concrete stain?

I think the OP is overly concerned about the condition of something that existed when the property was bought years ago. I would have been much easier to correct then since it may have been a paint job just before the home was listed.

I don't think the "staining" of the concrete is related to the paint spots. Staining might help since it can produce a variable appearance.

Should I something like paint stripper or formia/muratic acid?

Any kind of translucent/transparent/opaque stain is still going to allow the existing variation in color show through, plus it would certainly need a cleaner substrate than you currently have to bond sufficiently. If a solid-colored stain is what you desire, they certainly have issues of their own, and you're still going to need to clean the stains better.

I wouldn't recommend using muriatic on the stoop either, as it will cause even more color issues. A paint scraper with some elbow grease should remove the paint splatters in short order. If not, a simple, safe product like "Goof-Off" or the like should help soften them enough to scrape off.

Heat gun. It'll remove paint that is older than dirt.

Or ... simply more elbow grease.

What's the best kind of paint scraper to try? In the past I believe I tried doing this without success. I can try again.

Tried that with no luck.

Wouldn't paint stripper be my best option here?
