Hello.
I want to fix this stove we have (the picture). The surface was plastered with rough texture sometime during the happy 70s, but now it's probably time to fix it.
What I'm thinking is to fill it smooth, but, yes, I need tips on what I should consider for a good result. Like, do I need to sand down the plaster or would it work to fill on the plaster etcetera etcetera...
Thanks in advance.
