如何在不損害環境的情況下標記人行道和草地


3

我正在尋找某種油漆在人行道上和草地上做標記,以便可以在一天左右的時間內清楚地看到這些標記。

噴漆可以達到目的,但對環境不是很友好。也許研磨鮮豔的粉筆並從鹽瓶中分配出來是可行的?

For pavement, how about chalk?

For grass, here are a couple of products based on crushed limestone: no affiliation, just the result of a google search. These only seem to come in white though.
