Pet stains on wall. Put Kilz oil based original sealer over stains. Do I need to seal entire wall? After painting wall will area sealed be noticeable if I do not seal entire wall ?
No, just seal up the spots that need it. The primed areas shouldn't be noticeable once painted as long as you didn't apply too much primer too thick. Always try to use the same method to apply the primer as was used to paint the wall, example- with a roller, and feather out the primer and paint.
