Using Chalk Instead of Paints in Paper Plaster

Instead of using paint, it is possible to manufacture white paper plaster by adding chalk to its ingredients. The moisture buffer values (MBVs) of paper plaster mixtures with chalk ranged from 1.8 to 2.9. The higher the chalk content was, the lower the MBV of the paper plaster was. Only the mix with the highest chalk content, where the percentage of chalk was 90, had a moisture buffering capacity below 2.0, i.e., not excellent (MBV > 2.0).
