I want to do some decorating this year when it’s warmed up a bit. I intended to do it last year but that wasn’t possible in the end, the furthest I got with that was buying the brushes. LoL. I’m going to try and redecorate my living room this year but upon inspecting it I realised my ceiling has a really nice pattern on it, looks a bit dated really but I like it.
Any-way I just wanted to ask what the ceiling is as it has grooves in it. Pictures below.
Is it ok to paint? Not sure if a brush will damage it as when I ran my finger across it it's a bit flaky 
Does it require a certain paint?
I don’t want to damage it as it is a pretty design. Professional decorators would probably be best of course but I really want to give this a go myself as I love painting and when I decorated my room during the first Covid lockdown it came out better than I thought it would.
So if you are an expert on these things please share your words of wisdom with me. But even if you aren’t an expert still share your words of wisdom because I have no idea what I’m doing!
