The invention relates to an adhesive composition comprising at least one latex and at least one polymer composition having a glass transition temperature ranging from &#x2212;50&#xb0; C. to 0&#xb0; C., said adhesive composition being particularly suitable for bonding flexible surface coverings having a high dimensional variability. The invention also relates to a membrane obtained after drying of the adhesive composition according to the invention, a combination of a flexible surface covering with an adhesive composition according to the invention, a method of application of a flexible surface covering onto a substrate as well as a substrate covered with a peelable adhesive membrane according to the invention.

Peelable adhesive composition

The invention relates to an adhesive composition comprising at least one natural latex and at least one polymeric composition having a glass transition temperature ranging from &#x2212;50&#xb0; C. to 0&#xb0; C. The invention also relates to a membrane obtained after drying the adhesive composition according to the invention, to a combination of a flexible surface coating with an adhesive composition according to the invention, to a method for applying a flexible surface coating onto a substrate as well as a substrate coated with a peelable adhesive membrane according to the invention.

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.

A coating composition of: Use thereof and the applications thereof as smoothing and/or heat-insulating coating for walls and ceilings.

Wall and ceiling coating composition having heat insulation properties

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.
