Tips and Techniques for Using Ampersand’s Claybord

Part two of our Claybord 101 article offers up some tips and techniques for working with various mediums on Ampersand Claybord.  Have any tips of your own?  Leave them in the comments section!

Tips and Techniques

  • To remove a mark, gentle strokes with Ampersand’s oil-free steel wool may be used.
  • Claybord’s coating is thick enough to use a razor blade or scratch tool to reveal the white clay beneath a layer of painted color to give detail and definition to a painting.
  • If you are interested in sealing your work in watercolor, ink or scratchbord for glass-free presentation, we recommend using the Krylon® UV Archival line of spray varnishes.

India and colored inks

  • Apply India ink in layers of diluted washes for soft charcoal-style effects. Then, after the surface is dry, use Ampersand’s oil-free steel wool to create a wide range of soft tonal values or to completely remove the ink without damaging the clay surface. Using Ampersand Scratchbord tools, remove the ink as if you are drawing fine white lines.
  •  Some inks and dyes will permanently stain the clay surface and should be tested first on a small area.
  • Scratchbord-Claybord Inks are formulated for Claybord– they will not stain the surface and are easy to manipulate and scratch through.
  • Claybord works well with pen and ink as fine lines do not smudge and the ink dries rapidly; however, take heed to prepare the board by dusting and wiping down to prevent clogging of pens

watercolor and gouache

  • Painting on Claybord with watercolor or gouache is like working on hot-press paper or illustration board.
  • When using these mediums for clean calligraphic lines, use less water or a dryer brush.
  • After the surface is completely dry, watercolor can be lifted or scratched off with the Scratchbord Tools, an X-acto™ knife, oil-free steel wool or with a wet brush.
  • Make sure the surface is dry before scraping or you might remove too much clay.
  • Many watercolorists prefer Ampersand Aquabord over Claybord because it is more like using a cold press watercolor paper.


  • Acrylics can be applied on Claybord in both washes thinned with up to 25% water and heavy impasto made with gel and texturing mediums.
  • When planning to scratch into or remove acrylics, apply them sparingly because heavier acrylics dry to a very hard plastic film.


  • Claybord is the ultimate surface for airbrush. Colors absorb quickly and remain bright.
  • Instead of using frisket, scratch out fine details back to the white surface underneath.

Casein and egg tempera

  • Claybord is ideal for casein and egg tempera, considering the fragility of these ancient mediums. Both are prone to cracking when dry and need the stability and absorbency that only for good adhesion, apply several thin washes of paint first, allowing each layer to dry completely in between. Then begin painting fine details, gradually working your way down to smaller and smaller brushes as the painting progresses.


  • First layers of oil paint will dry rapidly to a matte finish, due to the absorbency of Claybord. Subsequent layers will dry more slowly and keep their luster.
  • To keep the oils from absorbing into the panel’s coating, consider using Gessobord or following these steps to prepare the Claybord for oil paints.

Dry Media

  • Softer leads with high pigment content work best on Claybord when using pencil or graphite. Claybord tolerates repeated erasing without marring the surface and can be sealed and framed without glass.

    This article is really not helpful. You merely state the obvious! I’m trying to find video demos on how to use this interesting surface & apparently in all of the Virtual world, there aren’t any! I’m a member is the ISSA – International Scratchboard Society, so I am seeking to use Clayboard as an extension of my BLACK surfaced – Scratchboard work. I am a Wildlife – Raptor Artist. A demo creating a Wildlife scene on Clayboard would be great! Especially on YouTube!

    Hi Justin!
    Thank you for checking out our articles and for your interest in Claybord! It sounds like you’re looking for an online demo where the artist is making and completing a wildlife artwork. I don’t know if that exists, but I will look around online.
    While we weren’t trying to state the obvious, this article was intended to be a “101” primer or introduction to the surface. Thanks for your request for something more advanced, focusing on the creation of an actual artwork. We may end up making a video like that ourselves.
    In the meantime, is there anything in particular that you’d like to know about using Claybord like a scratchboard? Please email me at dana@ampersandart.com with any questions at all.
    Thanks again! Dana Brown

    How does one protect a finished claybord painting? I’ve used aquabord, but hesitated to use claybord out of concern regarding unintentional scratching on a finished piece. I’m a watercolor artist (hence the aquabord), if that factors into the method you would recommend.

      Hi! The process that you would use to finish/varnish a watercolor painting on Claybord would be the same as for Aquabord. Once the work is completed, use a spray fixative to “lock” it in place. We recommend either Krylon UV Archival Varnish or UV Resistant Clear. Then, use Golden Artist Colors’ Polymer Varnish with UVLS as a final, brush on application. We recommend 3-4 coats. Please feel free to email me at bords@ampersandart.com if you have any questions. Thank you! – Dana Brown
