Removing Paint from stone window cills

beggars_bush

We have an old cottage with exterior limestone (we think) window cills. they are punched dressed

these have been painted multiple times by previous owners but we would like to now clean all the paint back and see what shape the stone cills are in and go for the bare look - mainly because we are also changing the windows in house.

any suggestions or experience with stripping this paint off? There is probably layers of gloss paint on them under the more recent paint

Firstly, I'd do a test area to make sure they're definitely dressed limestone. You could try a heat gun and wire brush on one end of a cill. Unfortunately Nitromors isn't very good any more but I've had good results removing old paint from stone by soaking rags with cellulose thinners, laying them on the surface to be stripped, covering over with plastic bags and sealing the edges with tape. Leave for 24 hours, remove the plastic and rags then quickly scrape or wire brush off the old softened paint.

Keep repeating that process until all the heavy paint is off, then rinse off any remaining paint residue by scrubbing the stone with more cellulose thinners and a new paint brush.

A reminder, cellulose thinners is highly flammable so absolutely no smoking and only use this system outdoors or in a very well ventilated area.

Or you could also just invest in a compressor and soda blasting gun.

Best way to do this is by sand blasting them
