How to use adhesive for floor tiles?

Hi, I would like to install vinyl tiles on concrete floor using Henry 430 vinyl composition tile adhesive. The instructions say to leave it for ~90 min. until the floor feels tacky and then I have 24 hours to lay the tiles. My question is, how do I cover a large area of the floor with this adhesive and then walk on it to lay the tiles if it's going to be sticky? Please help, I'm hoping to do this tonight. Thank you.
