  • Patent number: 8344056
    Abstract: A method of covering an anomaly in a wall substantially to match a pre-existing texture pattern surrounding the anomaly. The method comprises the following steps. A valve is supported on a container assembly to define a main chamber. Contained material comprising wall material concentrate and propellant material is disposed within the main chamber. An actuator relative is arranged relative to the container assembly such that displacement of a button relative to the valve changes the valve from a closed configuration to an open configuration in which a portion of the propellant material is allowed to force the contained material out of the main chamber through the outlet. A first portion of the contained material is applied to the anomaly by directing the outlet at the anomaly and displacing the button. Optionally, a second portion of the contained material may be applied to the base coat by directing the outlet at the base coat and displacing the button.

  • Publication number: 20120238684
    Abstract: A method for manufacturing an aqueous suspension of calcium carbonate by grinding in an aqueous medium in the presence of an acrylic grinding aid agent and of an alkaline carbonate salt. These salts enable the quantity of grinding aid agent used to be reduced, for an equivalent level of performance in terms of rheology and granulometry of the suspensions. The method includes a first step of manufacture of the alkaline carbonate salt within the aqueous solution of acrylic polymer itself, through the addition of alkaline hydroxide and bubbling of carbon dioxide.
