Silk Screening Base is a water-based product designed to adapt Tri-Art acrylic colours to the silk screening process. This product is designed for use on paper and other fine art supports and is not suitable for silk screening on clothing. This medium significantly retards the drying process of acrylics facilitating the cleaning of the screen. The gel-like consistency of the medium produces a crisp print with no bleeding. Combine with High Viscosity or Liquid acrylic colours at a 1:1 ratio. Clean silk screen and tools with soap and water. To remove stubborn dried paint, soak the screen in warm water for a few hours then scrub away the remaining paint.
