I'm repairing a flat concrete roof which has spalled a bit in one corner
(posted about this a few weeks back actually); could I have some
recomendations for how to finish off the top surface afterwards? The
whole area is about 10m2; it was previously covered with the crabby
remnants of some form of bitumen-based stuff which I've just blasted off
with some help from my mate Karcher.

Screwfix seem to have a huge variety of different roofing chemicals, and
I haven't a clue which to go for.

I'm thinking this one?

Why not use the solvent-free one?
