Today I tested out different concentrations of polymer : water to cover the casts. Although I have added polymer into the plaster, I want to add an extra layer of diluted polymer so that the works will be stronger, the surface will be protected, the colours will retain their vibrancy, and to enhance the sheen on the surface.
I tested the different dilutions on this scrap sheet of plaster
The stronger the polymer concentrations, the more it seemed like an added layer, and it also became cracked, so I will use a more diluted version.
This image shows where the polymer has cracked
I also began a new batch of casts, and these are some of the colours I used.
