34theletterbetweenB&D Posted November 30, 2016 Share Posted November 30, 2016 My dear wife found a very aged and unopened tub of natural yogurt at the back of the office fridge. She brought it home, as the office expert on these matters told her it is very effective to speed the ageing of stone or concrete surfaces, and we have a birdbath the column of which looks rather raw and new, despite twenty some years outside. Instructions were given to the household minion, and I duly applied the entire quart to the surface yesterday. Since there was quite a lot of the (clearly very natural and alive) yogurt it made an impressively thick coat on the column, 4 or 5mm deep I should guess. Now, I have just trotted in from the garden, having talked to the greenhouse, checked the gate fleecing, locked the delicate plants, yada, yada, yada; and while all this was underway realised that there was a not a smidge of yogurt to be seen on the birdbath column, that I so lovingly smeared but the day previous. Had something licked it all off? I lifted the bowl off the column as I had smeared the top of the column too, all gone there too, despite being inaccessible to any passing licker. On feeling the surfaces where the yogurt had been applied they are all interestingly waxy... So who knew that? Concrete eats yogurt. Link to post Share on other sites More sharing options...
brossard Posted November 30, 2016 Share Posted November 30, 2016 Perhaps there's the beginnings of a paper to be read at the next Geological Society meeting. John Link to post Share on other sites More sharing options...

Fat Controller Posted November 30, 2016 Share Posted November 30, 2016 We certainly used soured milk to age concrete 'stone-effect' blockwork at a site in rural Carmarthenshire over forty years ago; a job best done on the Friday afternoon before a Bank Holiday weekend. Yoghurt hadn't reached Llangadog at that point, and probably wouldn't for another twenty years. Link to post Share on other sites More sharing options...
RMweb Gold Tony_S Posted November 30, 2016 RMweb Gold Share Posted November 30, 2016 Our birdbath gets so weathered by moss that I am expected to power wash it occasionally so my wife can admire the granite. She likes granite. Link to post Share on other sites More sharing options...
Horsetan Posted November 30, 2016 Share Posted November 30, 2016 Of course, if you put yoghurt in the freezer, you eventually get concrete yoghurt. But that's not important right now. And it's healthy for humans to put inside their bodies? Don't worry, if the stuff I regularly consume is anything to go by, it exits the body pretty quickly as well.... .... so my wife can admire the granite. She likes granite. Send her to Aberdeen for a holiday. There's plenty of it there. Link to post Share on other sites More sharing options...
RMweb Gold chris p bacon Posted November 30, 2016 RMweb Gold Share Posted November 30, 2016 the office expert on these matters told her it is very effective to speed the ageing of stone or concrete surfaces It will encourage moss and algae to grow. There's one better than that though, about 20 years ago the bricklayer and I took great delight in flinging cow sh1t at a stone wall we'd built to age it, all the better as some missed and the customer was not one of our favourites.....I'm still waiting for the cheque to clear....
