Any ideas how much time to allow?
It will mostly be me doing sealer and two coats of paint. Will have help on weekends etc. I need to book in floors but want to get painting done first...
It depends a lot on how fussy you are with cutting in and patching. If you want a completely "perfect" surface then you'll need to fill any indents and minor marks and then sand smooth. The cutting in depends on whether you plan on masking it or just using a steady hand..... If you're painting a light colour and you cut in using a fairly thick brush coat you may get away with only cutting in on the sealer and first coat, then just roll as close as you can to the edges for the final coat.
I would think it would take a single person at least 4 days, more like 5, to do the whole house.
