A flooring system includes a plurality of tongue-and-groove panels, and a preglue. When activated, the preglue has a tensile strength of 7-20 kN/m when measured with a gap less than 0.1 mm and a pull rate of 2 mm/min; a storage stability of at least one year; a low initial tack value; and a set time of at least 45 minutes; as well as a creep strength of between 7 and 20 kN/m, when measured with a gap less than 0.1 mm and a pull rate of 0.02 mm/min.
