Do you apply an isolation coat to your acrylic/mixed media art paintings? I recently learned about this important step in preserving paintings. According to Golden Paints:
"An isolation coat is a clear, non-removable coating that serves to physically separate the paint surface from the removable varnish. The isolation coat serves two purposes:
- To protect the painting if/or when the varnish is removed by separating the pigmented area of the painting from the solvents used in removal.
- To seal any absorbent areas in order to create an even surface on which to apply the varnish."
Check the Golden Paints link for the details on this technique.
