What's the best point to use to flood holes made by nail within your wall beforehand you paint?
Answers: I use spackling compound and apply it with my finger and consequently use a wet microfiber cloth to remove any excess around the hole. I dislike intensely it when painters apply it near a putty knife and it shows when you paint the wall.
buy some 'lightweight spackle' and a putty wound. apply using the putty knife, human being sure to not let any excess spackle on your wall...
