Can I ‘dilute’ the mix
I mean I don't know if you should or by how much you are talking about, but this is basically what I did.
I used those little plastic fibre things to bulk out the mix for filling and forming missing bits, block sanded back, filled, block sanded, then made a runny mix which I skimmed, block sanded, skimmed, block sanded, etc.
I also bought a multipack of trowl things from Screwfix and used a mix to get the neatest finish I could.

I’ve been building up an old external windowsil with Toupret masonry filler, using a questionable cake-icing type method, and naturally the results and very pretty.
Can I ‘dilute’ the mix with a bit more water to make it runnier without compromising it’s strength? Will it just take a bit more time to cure?
Planning on getting some melamine board to make some rudimentary formwork.
Here’s a before; current; and what had been growing in the middle (judging by the top inch or so that crumbled off it’s previously been ‘repaired’ with sand-cement, without grano)
