spackle or compound over silicone residue

We hired a painter to re-mud the bathroom as the paint peeled off (whole nother story), and we wanted him to patch the gauges around the tub surround that are jagged and uneven, most 1/8-1/4" deep as well as some small holes about 1/2" deep. He didn't patch to repair the gauges, rather he added caulk which looks awful, so I proceeded to dig it out and redo myself. I know painters like caulk but I thought it was a huge "no-no" to use silicone on painted surfaces. My question is can I leave residual silicone caulk and spacke or joint compound over the residue or even the full bead of caulk. It's a nightmare to remove this stuff, but I wwanted it done right. Which would you recommend, spackle or compound or even caulk and spackle? Thanks for any help

It really depends on how much silicone is there. Joint compound won't adhere to silicone but it will adhere to the surrounding areas - if that is enough, it will be ok. Otherwise it would be best to prime the areas in question with a pigmented shellac like Zinnser's BIN. It will adhere to the silicone and the j/c will adhere to the BIN.

As a painter I also like caulking but I also believe in using the correct material for the job at hand. Not sure why he would have used caulking when he was hired to fix it with j/c.
Even if he had to use caulk, why silicone hope you didn't pay him for that work!

btw - welcome to the forums!
