Hello, I asked this earlier and got it all wrong. Again, apologies for wasting the time of the 2 kind people who answered. The problem is that I have gloss paint on my external concrete window ledges. The paint is flaking and cracking, and letting in rainwater. I wonder if you could tell me the best method of removing the gloss paint (the windows are UPVC, so I need to be careful). And do you suggest using stabilising solution before applying the masonary paint to the window ledges? Any other advice would be appreciated. Thanks
