Depending on the quality of the job, limewash can last 5 to 30 years. I would just let it weather and see what happens. You could also remove the stone and replace it with wood, painted to match the house.

The limewash is unstable for a few days. I'd try to wash/scrub some of that off so the stone looks less like plastic. The biggest issue is that you limewashed the mortar. Holding onto that color would have gone a long way to making the rock look more realistic.

I think this is going to turn into a giant art project with your trying to add some other limewash colors to the stone to bring back some interest.

I would power wash it again and try to get the limewash off. It doesnt look great thats for sure. Lime wash always looks dirty to me.

Be careful. It's likely that just a regular garden sprayer on your hose would have kept your from this problem. Power Washing is just brutal and it's too much force for many surfaces.

These installers are just using a regular hose with sprayer attachment to remove the limewash

Use the Romabio in the different colors to get the stone more varied.

Romabio is what we have (its bianco white) and I have small cans of riposo and toscana beige. It will obviously be much more of an undertaking to fully cover the rocks, but it may need to happen. I can easily remove some with washing, but I am not sure it looks much better.

One day we will likely remove the veneer and siding and update with our own taste. Unfortunately, that will be several years down the road so just trying to make this not look horrible. Thank you so far for everyone’s input. This is the whole house from far away with a little removal (too much on some stones on the pillar).

I think the white sticks out, and not in a good way. Maybe repaint in a color as close to the color of the beam above them, as you can get.

I think the house could benefit from deep color tones overall.

Start spraying it down tomorrow. Get off what you can. Bring it back to as much of what you started with as you can. Then show us pics so we can help you with a game plan. It might not look great after you spray it off, but it will give you more options for how to move forward.

I can try to spray it off. Unfortunately, I did this 1-2 months ago and have been trying to figure out next steps during that time (and give myself time before doing anything rash). We only have a few warmer days left and I do worry trying to get it all off will leave me with an even bigger mess. However, if the consensus is this isnt salvagable except to start over then that is what Ill do.

I dont think, what you have is salvageable. I would remove it. Stones painted are not always the best look, no matter what you use, but, the white really doesnt look good. It looks like plastic in your pictures. Remove as much as you possibly can, and post a picture. If it needs new paint after you get it cleaned off, then, it needs to be a color that matches the beam above it, so it blends in a bit, instead of sticking out like a sore thumb.

If the finish has been on that long it's not coming off. At this point, I wouldn't waste effort trying to get it off. Apply your different colors over it, but don't forget to address the mortar color before you apply anything to the face of the stone. You'll want this to blend.

Thank you all for your advice. l will post the final results when I am able to get it all off. I was really hoping to avoid pressure washing it all off, but i think it is what needed to happen. I managed to get a decent amount done in 3 hours today. It will definitely take awhile to get it all off though!

Actually, what you have right now, looks many times better than the white did. If all that came off in 3 hours, maybe just leave it now, and see how you like it, in the spring. I did just notice you havent finished yet, so just finish the rest of it, and see how it all looks. I cant see up close, of course, but, in your picture, it is many times better, the stones look like stone again, and the colors in them, blend with your roof and house, so many times better already.

No advice here, just an observation.

A lovely little bungalow on my street has short natural stone pillars at its front porch. Similar to yours. I was aghast earlier this week when I walked past and saw they had painted the stone white. I assume it was real paint as it looks thick, gummy and unnatural. What a shame.

OP, it’s only the front 2 pillars that look “off” on your house. I don’t think you need to remove all the rock, just the front 2 pillars. They may look better with rock around the bottom third (to match the rest of the house) and wood on top; and not triangular.

I think the little bit you have done looks better already.
