Sandstone waterproof, soak how long?

Answer:

It should be directly coated with waterproof paint
I do not buy the sandstone profiteers waterproof, 1 months after the installation after the discoloration, washed with acid and hydrogen peroxide side, now water can do it, thank you!!! No problem as long as you choose the material no problem
Sandstone waterproof, can directly brush stone protective agent ~!Sand can be used to paste sandstone sandstone, without soaking, direct construction paste, convenient and quick.
