To ensure the drawing’s integrity and stability, the ArtGraf Nº1 was developed to fix and dry quickly, allowing the work continuity even when used on wet surfaces.
Keep the package sealed in order to keep the humidity.
What to do when the product dries out even inside the packaging?
If you notice that the putty shows signs of excessive drying, add water, incrementally, depending on how adaptable you want the material to be.
When the product shows to be completely dry, you can fix it just with the addition of water in the packaging itself, wait 1 or 2 days and it will return to its initial state. Treat it as clay.
