It’s called “decorators caulk”. 
 

More severe gaps should be filled and finished with Tupret filler.

I should add, if you’ve chosen your plasterer very well, same for the carpenter, you should need very little of either.

I don't know the Toupret product so used your link.

The description says it 'does not flash or grin' .

That's good to hear, except I don't know what that means in this context. Do you know?

The Toupret stuff is very very good filler. You can put a hairdryer on it and accelerate it drying, and then sand it straight away without any issues. Most would curdle or open up with a bunch of cracks. 

 

Sands down very easily too.

 

Found this stuff a good 15 years ago, when I employed a fantastic painter and decorator for a knock through extension,  and I’ve not used anything else since.

Thanks. 

What do you recommend for external wood filler?  Weatherboard, mostly ancient,  where knots have pinged out, some boards where becoming porous on the surface (or chewed by wasps perhaps,) and some badly holed or split feature blocks. That may be 2 different products required according to the hole sizes.

I've used Ronseal and really don't like it for handling or for the ability to smooth or shape it.

I’d use something 2-part, but in honesty I’ve not done much exterior filling. 
 

Scarfing new wood in is the no.1 best way to do wood repairs though.

That's not happening I'm afraid.

When I followed your link I saw that Toupret do a big range of  external products, 

 

I will look into this powder one for the smaller work and maybe a resin one for big gaps.

Well I tried Geocel painters mate on a junction between plaster and rooflight frame.

Didn't like it, I might have to try and pull it off again. Kind of like a bath sealant that goes off 3 times faster - might be ok for an internal corner, but bit of a nightmare to smooth out with a finger on a flat junction. 

 

As for plaster against glass on the other rooflight - think it will have to be painted as is, but not sure about my cutting in on that.
