No, it would take a long time to infiltrate.

Hold water for 48 hours, then go downstairs to see if there is any leakage.

Dig the best permeable waterproofing can be done by yourself.
If the cement surface is to be waterproofed, use the super permeable waterproof guard of the black gold steel to do waterproofing (if it is incomplete, use the dug beautiful butadia glue to fill the complete and then do the waterproofing).
For the tile surface, first check whether the filling of the tile gap is complete (if it is incomplete, fill it with dug beautiful butadia glue, and then use the black gold steel stone tile type to do waterproofing).
Personally, I think that a reasonable process for bathroom decoration, waterproofing, waterproofing, water and electricity, protection and tiling is as follows: >>>More
Three points of material and seven points of construction. >>>More
48h...Two days.
If the bonding is not good, the waterproof layer is susceptible to damage. Let's rework!Once and for all!
If you follow the color of the cement you said, the shape is also like cement! If it is all, it is JS waterproof coating, which is relatively expensive! The words of the contractor will not exceed 35!
