Patent

CA 2487661

A method for improving the adhesiveness between hardened cement compositions and resin coating materials by spraying an aqueous solution containing organic acid(s) which will react with the surface to produce calcium compounds on the hardened cement surface before a resin coating material is applied, thus removing the carbonate membrane of hydrated cement compositions. This improves the adhesiveness between the hardened cement compositions and the resin coating material.

L'invention concerne un procédé permettant d'améliorer l'adhésivité entre des compositions de ciment durci et des matériaux de revêtement à base de résine, par pulvérisation de solution aqueuse renfermant un ou plusieurs acides organiques qui réagissent avec la surface, pour donner des composés de calcium sur la surface de ciment durci avant l'application de matériau de revêtement à base de résine, permettant d'éliminer la membrane en carbonate des compositions de ciment hydraté. On améliore ainsi l'adhésivité entre les compositions de ciment durci et les matériaux de revêtement à base de résine.
