Caulking
Q: Is it necessary to caulk between wall and baseboard molding? Should only a certain type of caulking be used? If caulking is necessary, what is the best method to get a clean, neat edge so that the job does not look sloppy?
A: No, it is not necessary but highly recommended. Caulking on the interior of a home is purely cosmetic. It makes the job look much better.
You want to use a paintable acrylic caulking. Do not use silicone.
It is best to paint over all the caulking with the wall color to the top of the baseboards. Then paint the top of the baseboard with the baseboard color. This will be the best way to ensure a clean edge.
