Levelling process for a construction floor in order to renew it, and levelling composition therefor.

摘要

The invention relates to a method for levelling an existing construction floor with the purpose of renewing it by laying a new floor covering, in which the said floor can be of any kind and can comprise surface irregularities and asperities formed by fragments or traces of adhesive originating from a previous covering which would have adhered to an underlying support and which would have been disbonded; to the floor to be levelled is applied a layer of an essentially curable composition formed from at least one polymer binder chosen in order that the coating formed after curing of the said layer can adhere to the existing floors of any kind and exhibits a perfectly flat surface, enabling direct laying of the new covering, and a height sufficient for making up differences in level generally encountered on floors to be renewed.
