intumescent mastic is fireproof, at least it expands when it's exposed to the heat of a fire. Mostly useful around fire doors etc.
There are lots of normal mastic/sealants you can use but they tend to discolour over time so they mostly need painting. Hard but flexible fillers like elafib are great and very durable but they shrink in these applications so it requires multiple applications and still needs painting.
Fossa caulk savers can be pushed into the gap under the skirting to save using tons of mastic. They also mean a normal decorators mastic can be used but decorators mastic really needs to be primed and painted.

I need to fill some floorboard gaps and skirting board gaps. Neighbour is using some kind of scent diffuser and it's coming through the gaps. I can feel the draft and it stinks, it's unfortunately under my desk so I spend most of every day sitting there being frustrated by it!
I'm guessing Bona gap master for the floorboards, and something else (intumescent mastic?) for under the skirting.. between the boards can be black as it will match the old previous filler.
