Re: Caulk Where Backsplash Meets Wall?
I would caulk the splash to the wall, but I wouldn't waste money or time with silicone, use a good latex based caulk. Latex is MUCH easier to work with and can be replaced and/or reapplied as needed.
Silicone is extremely difficult to work with, fails just as readily as any other type of caulk, with the added insult of being near impossible to remove, and new silicone will not stick to old silicone, so you will have all sorts of fun trying to remove the old well enough to get something else, anything else, to stick.
Save yourself the headache and just go with latex based caulk.
