The invention relates to an anhydrous cementitious coating composition consisting of a hydraulic cement in the range 30-70 % w/w polymeric particles having a Tg less than 25 ~C in the range 5-25 % w/w, and mineral extender particles in the range 5-50 % w/w. The cement to mineral extender particles are in the weight ratio 5:1 to 1:1. When mixed with potable water these compositions form useful decorative or protective coating compositions for application to a range of substrates.
L'invention concerne une composition de revêtement à base de ciment anhydre constituée de 30 à 70 % en poids d'un ciment hydraulique, de 5 à 25 % de particules polymères possédant une Tg inférieure à 25 ·C et entre 5 et 50 % de particules diluantes minérales. Le rapport ciment/particules minérales et compris entre 5/1 et 1/1. Lorsqu'on les mélange à l'eau, ces compositions constituent des compositions de revêtement décoratives ou protectrices pouvant être appliquées à plusieurs substrats.
