Has anyone found a good while silicone sealant that doesn't Shrink?

I had to make a quick external repair less than a year ago. The Soudal I used went on well, but it's shrunk a good 10% and pulled away.
 
Do you really want silicone sealant? I tend to avoid if possible because not paintable. Five years ago I replaced doors and windows in my brick-built garage and used white Screwfix No Nonsense exterior frame sealant (acrylic and paintable) around them. After about four years it had shrunk slightly leaving voids in a very few places, which filled easily with a little of the same sealant (I don't think silicone sealant ever sticks to itself well). I never got round to painting it but didn't need to: after five years it is still acceptably white. I have found some SF No Nonsense products a bit poor but this one seems good.
 
Google "low modulus silicone" they allow for more movement.

That said, silicone should not shrink.
