Removing barn paint from stone foundation

[JD3020]

Fiance and i are getting married in my grandparents bank barn this summer. It was built in the late 1800's/early 1900's(some discrepancies in the records), my grandparents have been raising cattle and putting hay in it since 1958 and we are hoping to take over and continue the family farm.

Anyways its a beautiful old barn, all large hand hewn beams and laid stone foundation. 5+ years ago he had one of the local crackhead paintdrs paint the barn and they did a horrible job, overspray on everything. He made them re-do all the trim but the windows(glass and plexiglass) and stones are still red. Need to find a way to clean the stone and windows without damaging anything, but also without taking me the next 6 months to do. Ive been using a scraper on the windows but most of the panes have been replaced with plexigass over the years which makes it hard to scrape anything off of them. I believe they used latex paint. This is a picture from a few years ago, need to get some current ones of what i want to clean up.

I’d try graffiti remover or pressure washer if SHE is insisting. Otherwise leave it be and focus on important things. No one will notice if they are there for you.

Agree
Media blasting might work too.

For the stone, I stripped a brick fireplace that had been painted multiple times. Started with aerosol paint stripper and a wire brush. Then went to acetone sprayed through an hvlp to "rinse". Wasn't fast or fun but afterwards people thought I installed a new fireplace.

A gas powered pressure washer may work on the stone, but don't get near the wood.

Or the mortar unless you want to repoint it (which may be the quickest way).

I wouldn't sandblast the stone as it might change the apperance of it drastically. Jasco makes a paint and epoxy stripper that work very well. I use it to remove botched up powder coating that I've done. Amazon carries it liquid form.

If you're in a hurry, you could just paint the stones 4 shades of gray. nobody will notice. You should not even try to remove paint from plexiglas. I have had paint remover that was designed for plastic. there is such a thing. I would just reglaze the windows instead.

If you start pressure washing the stone, you will need to do all of it because it typically "whitens" the stone, similar to using a media blaster. Any over-spray with pressure will remove the patina on surrounding stone and then the can of worms is open. The pressure might also disturb the mortar which then presents another can of worms yet. I would let it be and not touch it.

Soda blast the stone.

Not sure the size of the project... I did remove two large decorative about the size of 1x2 feet each with paint remover, scrape, wire brush on a drill, and repeat.. then power wash at the end... It had few layers of paint from previous owner(s), probably lead paint too.... but anyways...

Red Devil lye followed by a pressure washer.

I'd use paint stripper. brush some on, cover it with plastic cling wrap to keep it from drying out, then when it's ready remove the plastic, scrub with a stiff nylon brush and rinse with a hose.

Dustless blasting.

 

[MFolks]

Carbon Dioxide blasting or Bicarbonate of soda blasting?

 

[vtcat]

Yes, Dustless Blasting

The plexi is going to be a problem. You can blast stone obviously -- Have you tried pressure washing the stone?

They don't use "sand" anymore around me -- all kinds of items are used depending on needed abrasion
