If I tile my laundry room tonight, how soon formerly we can way of walking on it?
Answers: I tile every day of my go, and in some benchmark,,,as suggested, it depends on conditions in that space. Certainly no smaller quantity than 24 hours is a standard. That might extend if you intend to replace weight on the floor, IE: Washer/Dryer.
What is the substrate the tile is on? What substance did you use to install the tile? What is the broad temp. and humidity?
To WALK ON IT, you might assume as few as tomorrow morning, and certainly you can check that
If you use a thinset mortar it will set up plenty to walk on fussily in almost 8 to 12 hours. The mortar will not be cured or hard, but it will be stiff ample to take counterbalance. Just do not jump around on it or hit it near any sharp blows and it will be fine. So if you do it tonight it should be safe to step on by morning.
