Lime vs. Non-lime Color Differences


When using Lime Putty with American Clay Earth Plasters, be aware that the end result of the color will be different than a non-lime finished American Clay plaster surface. Lime Gauged plaster is lighter and brighter in color whereas Lime Washed plaster is more vivid and brighter in color. See the nearby pictures for an example of these changes.



How Lime Putty Affects Color


When deciding which color to mix with your Lime Gauged or Lime Washed American Clay Earth Plaster, here is an important point to consider: lime has a dramatic effect on ultramarine blue pigments, and our current pigments are not lime-safe. In a very short period of time, Lime Putty will

eliminate the color. The longer Lime Gauged clay sits wet with ultramarine pigments, the more likely it is to degrade the color. We recommend mixing, spreading, brushing and / or drying your clay wall within 12 hours so that the color remains intact.



Colors Containing Ultramarine Pigments


The following is a list of our standard colors that contain pigments that will degrade when combined with lime. Blended colors which contain the standard colors listed below are also not lime safe. Review it carefully, as some colors may not appear to contain ultramarine blue at a glance in the color packs:
