I would like to knockdown a ceiling (newbie) and read that it is desirable to add white paint to drywall mud. It seems reasonable that it would be preferable to have the color 'built-in' to the mud so that it never needs painting. I do not know the color of drywall mud, but it would seem that it is not quite white
This is the desired outcome:
Is there a 'recipe' that provides for the amounts of water, paint, etc?
Bonus round: Is there a rule of thumb for estimating paint / drywall mud based on ceiling area to be covered?
Edits to this post that sharpen the question is appreciated. Thank you
