How do I Tea-Stain Posterboard?
Tea-stained poster board can have an aged look. (aged paper image by javarman from

Using brewed tea to stain poster board allows you to create an antique look in moments. Tea, a natural dye, will often take to paper and most fibre-based materials to give them a light brown to sepia tone. Depending on the type of tea and the way it was brewed, you can produce different results in varying shades of orange.

  1. 1

    Fill a medium-sized pot with water and bring it to a boil.

  2. 2

    Place your tea bags into the boiling pot of water, and leave the stove on as it brews. Monitor the colour of the tea, keeping in mind that the dye's colour will be lighter than the colour of the water. The colour of the tea will become deeper the longer it brews.

  3. 3

    Once the tea reaches your desired colour, dip your paintbrush in the mixture.

  4. 4

    With the shiny side down, paint the poster board using the tea-dipped paintbrush.

  5. 5

    For deeper results and a wrinkled look to add to the appearance of ageing, transfer the tea mixture to a clean, plugged sink and submerge the poster board.

  6. 6

    Periodically check the poster board to make sure it hasn't become darker than you want it.

  7. 7

    Drip dry your poster board by pinning it to a clothesline or propping it upright.
