I've installed quite a few, mostly in my college days. These guys are lying, it's really a 3 part deal.
First step: Preparation
-Pick up a tub of KY flooring lube and go ahead and spread that sparingly all over that floor. Note: Sparingly, that stuff gets pretty goofy pretty fast and before you know it you'll be sliding in and out of rooms you never knew you had.
Second step: Warm up
-Now you wanna grab a broom and do short quick strokes, back and forth, back and forth...all over that floor. This engages the chemicals.
Step three: Penetration
-You take the product in question and spread it all over the floor, this will initiate a chemical reaction. Then take your pants off and quickly run to the corners of each room and jam in the crevasses. This ensures an even spread. I personally like to leave my calling card right in the middle of the room, but hey, it's your preference...get creative!
