Silicone render fix

[Renny]

I was doing a wall yesterday in a royal blue colour, and left a really bad line where I’ve not blended properly when floating, how do I go about re doing the wall? Does it need priming again? Or can I just go straight over what I’ve already done?
Any tips for getting it right? Sometimes it seems to work really easily and other times I find it really hard to leave no mark.
There’s three on the photo but the worst is easily the line to the right of the window.
Thanks for any help!

you can go straight over. youl get a bit more time going over silicone but not a great deal as dark colours pick up quick

As above


But make sure the sun is not on it or going to be on it. As it is in the pic, I'd work towards that elevation (that the sun is on (as that will warm quick.)


Or just do it on an overcast day.
