Applying external Filler

Hi guys. With 80 grit paper and a rubber sanding block I sanded down all the paint on the masonry around my front windows. I've bought some Touprelith F to fill some cracks and bare patches before painting. I opened the cracks a little more with my filler knife. The bare patches are where I removed any flaking paint. The bare patches are shallow, maybe 1mm or so, so I guess I better not mix the filler too runny or it'll just run down.

There's also a corner area where I removed a broken piece of painted material (plaster or some repair job) exposing what feels like expanding foam presumably from when my upvc windows were installed in 2012. Can I use the Touprelith to fill it and mould to the shape of the masonry, or should I stuff it with my exterior caulk?

And can I apply the filler straight to masonry, do I just moisten the areas with water first?
