1) Moisture-crosslinkable adhesive composition comprising: 2) Method for laying a wood-based covering, in particular a wide-block parquet flooring, on a flat rigid support comprising the distribution of an effective amount of said adhesive composition in the form of a substantially homogeneous layer.

Method for laying parquet flooring with improved dimensional stability

The invention relates to a notched spatula applicator () including gripping means () connected to a spatula () of which the straight working edge () is equipped with a plurality of notches () that are identical and evenly spaced apart by a distance between 35 and 50 mm, the width of said notches being between 9 and 18 mm and their height between 8 and 20 mm. The invention also relates to a process for laying, by bonding, rigid floorcoverings, especially parquet, which uses said applicator and an adhesive composition comprising from 0.2 to 5 wt % of substantially spherical particles of a material for which the substantially identical diameter may range from 1 to 7 mm. The invention finally relates to the adhesive composition used in said process.
