Removing so much Paint

[Minibiker]

Hi all

We moved into my wife's childhood home a couple of months back and we're in the process of decorating room by room, we're getting a new bathroom fitted within the next 2 or 3 weeks but want to get paint of the walls...

Basically the issue is, her dad painted on top of paint about 3 or 4 times and it's gonna be a pain to get of I imagine, Does anyone have any tips as to making it easier to remove please?

Thanks

I would have suggested Nitro Mors, but with the nerfed formula they use these days you'd be better off with something stronger like your creepy uncle's Brut aftershave.
