scratch-board-step9

My goal was to figure out the simplest and most inexpensive recipe to make your own scratch boards. This will probably not hold up to the professional grade ones, to those veterans out there, but it does give you a pretty decent result for a fraction of the cost. Also this recipe does not contain animal products like most high-grade art materials do. Please enjoy, experiment and share this concoction.

Steps

Step #1: Mix glue and water.

  • Gather your ingredients.
  • First, and as always, protect your work area. In a mixing container, combine 3 parts glue and 1 part water. Mix with fork until glue is completely disolved in water. Water should be white.

Step #2: Mix in plaster of Paris.

  • Add in 3 parts plaster of Paris.
  • Mix very well until there is no more dry plaster and mixture is a similar consistancy to pancake batter.

Step #3: Apply thin coat.

Apply one thin coat to wood board using a brush to act as a binding agent and wait a few minutes to dry.

Step #4: Apply thick coat #1.

Apply a thick layer going in one direction and wait about 10 minutes to dry.

Step #5: Apply thick coat #2.

Apply another thick layer going the other way and let sit to dry completely for 4-8 hours depending on how thick your coats are. If the batter's consistancy was right, it should paint on pretty smooth but expect to see some grooves from the brush strokes.

Step #6: Sand.

Once dry, sand down the plaster until smooth, using a medium-grit sandpaper (electric sanders work the best), and brush off all loose dust.

Step #7: Apply black mixture.

  • Mix together 3 parts black acrylic paint and 1 part dishsoap.
  • Apply paint/soap mixture using a foam roll brush or just a foam brush. You can use black ink instead but the paint mixture seems to scrape off the easiest.
  • Let dry for 8–24 hours before trying to scratch. The paint will moisten the plaster a little so it will take a long time to dry.

    Hi- If I have plaster walls could I paint them black and then scratch into that, do you think? Also, if walls are drywall, would that work? Have you ever tried just black paint overt different surfaces that are existing- like scraps of wall board….I have an empty house that I want to develop into a makerspace, studio but have so many ideas crashing around it’s been hard to get any done. thanks

      I haven’t tried that myself but if the walls are smooth then that might work. But it also might crumble away too easily without the glue in the mix, which is it’s binding agent. The paint on it’s own will adhere to the plaster and you won’t be able to scrape it off so easily, so the soap helps with that. That would be a gorgeous idea though. I am actually in the process of making a very large piece using this recipe and I will update you with the results on using this on a large scale!

    Thanks for the post. This looks fun. Why do you use the dish soap in the black coat? The pieces in your picture have color instead of white in the scratched parts. Is the color added after or do you tint the plaster?

      Same. I need closure on the dish soap issue:-)

    2. 0neir0naut says:

      Adding the soap to the paint allows you to scrape it off easier. The plaster will absorb the paint on it’s own and it won’t be easy to get off. Once I have scraped off all the black I want I use colored ink on top. Another idea (that I have not tried yet), is to add a dye into the plaster mix and then cover it with the black paint/soap mixture.

    I’m looking to make a sort of sketch book from bound scratchboard paper for practice before doing some prints. I know you typically use wood for scratchboard but since I’m going to bound them and they won’t be the actually finished piece – do you think a heavy / durable paper would work with your recipe? Thanks!
