Yeah but sooks like a c**t!need to be on the ball otherwise it goes all rubbery when trying to trowel up with plastic,dunno if be worth while painting with primer again or another pass with whatever it was coated with start again kind of thing,been a while since it’s happened to me but pretty sure it doesn’t hang about for long mate

yes its easy. takes a while to go off as no suction. but make sure no big chunks taken out of it. needs uniform surface to recoat

I recently had a wash off but it only caught the last 5 ft of the wall, so a mixture of TC and primer, rasped the TC so there was no visible step and primed the full lot It went on perfect no difference in drying times

So do you need to prime the silicone again if going over it also the washed off bits still have the primer visible on the basecoat with this be OK just to go back on thanks

I would just prime for what it's worth then not going over two different backgrounds
