Spent insane amounts of time on Newgrounds back in the day, still watch some of the classics (tank men, ultimate showdown, metal gear awesome, etc etc) from time to time. A different internet back then.
It wears down quicker than concrete (you can scratch it easily with a nail and minimal pressure). But we’re still talking 50+ years (before repointing brick, in my case). As long as maintained it’ll last forever (our home is 140 years old, I just re-did the pointing, should be good till I die).
Victorian brick houses are all lime based, pointing (mortar between bricks), render outside and internal plaster. (Ours is 140 years old ish).
Lime is also more flexible (these houses have minimal to no foundation and constantly move), it’s breathable (no/less damp) and as such it also improves air quality indoors. It’s annoying to do because drying times are days/weeks not hours, but long run it’s a far superior material for small buildings.
It does burn though if you accidentally get it on your skin!
