Or do you just keep topping up till you have a solid tyre?
The internal volume of a 700×25C tyre is about one litre. The dry residue of sealant is about a tenth of the initial volume. Topping up quarterly is about a tenth of a litre per year. The Fermi approximation of the time to fill a tyre with solid sealant residue is therefore 100 years.

I got a new bike a while ago with tubeless tyres already installed and now I am reading that
you should top up the sealant every 3 month. Is that only the case when you had punctures and
some of it escaped? Or do you just keep topping up till you have a solid tyre?
