Open the windows and doors to the room you are working in.
Plug in your hair dryer.
Hold the hair dryer close to the vinyl tile to heat the adhesive underneath.
Wriggle a putty knife beneath the tile and pry it up. Work up all the tiles throughout the room this way.
Put on gloves and a respirator.
Apply adhesive remover on the remaining adhesive on the floor. Use the adhesive remover according to label instructions, as most removers are specific on application, sitting time and removal. Failure to take up the adhesive remover in time can cause the adhesive to re-harden.
Remove the adhesive remover from the floor, using water and a rag, following the instructions on the label.
