Photocatalytic composition based on an aerial binder and use thereof forthe production of water-based paints, in particular for interior applications

Method of manufacturing a water-based paint, the method including the steps of adding water to a photocatalytic composition comprising

• (a) at least one aerial binder;
• (b) at least one photocatalyst;
• (c) at least one cellulose ether;
• (d) at least one fluidizing agent;
• (e) at least one pumice in the form of micronized powder;
• (f) at least one barite in the form of micronized powder;
• wherein the water/binder weight ratio is in the range from 0.2 to 0.8;
• and mixing until a fluid and homogeneous product is obtained.
