Hi. I have a 2m long venetian blind that ways just under 5kg. I'm trying to attach it in the recess about some patio doors. However, it's all plasterboard where I can attach it to. I used 6 brackets, attached using plasterboard plugs but after a few months it fell out. It always looked a bit precarious but with pulling the blinds open and shut it just came loose.
I've checked throughout and there are no joists behind it that I can attached it to. I considered a baton using no nails but was nervous it wouldn't be strong enough.
Can anyone advise the best course of action please?
