That was WAY MORE work than I thought it was going to be. If you want to hear God laugh, tell him what you're planning on doing after your weekend HI project.
Anyway, I got a box of topping and borrowed some knives and pans from the neighbor and got into it. Coat 1 took ~ 4.5 hours. Still have to sand and put on coat 2 and sand and prime and paint. Here are the pictures so everyone can feel a bit better about their first skim job 🙂
I coated it with Sheetrock Topping. Used a 6" knife for the whole thing so if anyone has some advice on cutting down the time that would be awesome.
