ABSTRACT:
A method of laying large surfacing and/or decorative floor panels or sheets upon a sub-floor with hot melt adhesives which have no solvents but are activated by heat and bond immediately upon loss of heat to a predetermined level, which method provides steps of running an adhesive undercoated 4.times. 8 foot sheet, for example, over a low profile heater on the sub-floor, and pressing the sheet to a preselected desired position on the sub-floor before the adhesive cools to mechanical bonding temperature and including removal of damaged or mislaid sheets by inverting the heater and running over the exposed sheet surface to heat the underlying adhesive to an elevated release temperature so manual lifting can remove the sheet without damage to the sub-floor.
