Some may remember my other threads but we bought an old gatehouse (1874). Decided to re-paint the inside of the front porch. I went to sand off some of the old flakey paint but some bits just peeled off. I grabbed a filling knife and started scraping the old stuff off. However rather than just taking off the top layer it seems it's been re-painted many, many times in it's lifetime and the paint is around 10mm thick before getting to the brick Underneath, particularly in the front archway, there was a ivy type plant growing under the paint and some of the bricks seems to be damaged and a little crumbly Also, in the roof part, i ended up uncovering old plaster and lath which i've partly pulled down I only started this about 4pm yesterday because in my head "sanding the front porch" was going to be a 30 minute job. As such i stopped after unearthing this as it was clear it was going to be a much bigger job than expected. Here's a pic of the porch as it stands now (and to give you an idea of the size/look of it) I presume that the best thing to do is strip the whole lot back to bare brick, however i'm not sure what's the best option from there as we can't then just paint using normal paint/render given the age of the building as it would damage the bricks. Plus to the left of the porch is our bedroom (the right is open to the elements) I'm also not sure how aggresive to be in my attempts to strip it all back. I started using a headgun, but given some bricks are crumbling is that too much? Any advice would be great!
