I very often end up stripping everything surrounding windows as it's such a mixed bag depending on the building. IR stripping works but I also chip a lot of paint and loose mortar off with a chisel. Sanding seems to take forever although it feels like it should be easier.
The proper masonry stuff, and yeah that’s kinda what I’m worried about.
Prob going to take another 9 months to decide colour so prob may never arise.
