How to Create a Weatherproof Paper Mache Mushroom


Welcome to the world of paper mache! In this article, we’ll explore the fascinating process of making a lifelike mushroom out of paper mache. Not only that, but we’ll also show you how to weatherproof it, so you can proudly display it in your garden.

Supplies You’ll Need

Before we dive into the step-by-step process, let’s gather all the necessary supplies. Here’s what you’ll need:

  • A plastic plate (around 9 1/2 inches in diameter)
  • A water bottle (you can also use a Pringles can or something similar)
  • Plaster
  • Plaster cloth
  • Masking tape
  • Newspapers
  • Paper pulp
  • Rust-Oleum LeakSeal
  • Acrylic paint

Step 1: Preparing the Base

To start, mix water with plaster and fill the bottle about one-third to one-half full. Set it aside to dry.

Step 2: Building the Mushroom Cap

Take the plastic plate and create the desired shape of your mushroom cap by crumpling up newspaper and taping it to the plate. Make sure to roll the edge of the plate to form the bottom edge of the cap.

Step 3: Adding Support

Cut a piece of cardboard to fit the inside of the cap. Find the center of the cardboard, make a cross-shaped incision to fit the plastic bottle, and insert it into the cap first. Secure it with tape and hot glue.

Step 4: Forming the Stem

Cut strips of plaster cloth and wrap them around the bottle to create the stem of the mushroom.

Step 5: Applying Paper Mache

Cover the mushroom cap and stem with paper mache strips or pulp. Let it dry completely, which may take some time. Don’t forget to create the gills under the cap for added authenticity.

Step 6 (optional): Smoothing the Surface

If desired, you can coat the mushroom with a thin layer of patching plaster to achieve a smooth look. Allow it to dry.

Step 7: Weatherproofing

After the paper mache is completely dry, spray it with a water sealer, such as Rust-Oleum LeakSeal. Apply 2-3 coats, making sure to cover all the cracks and crevices. Let each coat dry fully before applying the next.

Step 8: Adding Color

Now comes the fun part – painting your mushroom! Use acrylic paint in shades similar to the colors you’d find in nature. Experiment with dark, medium, and light tones to add depth. Consider using antiquing gel and blending gel for extra texture. Once you’re satisfied with the painting, seal it with a couple of coats of clear sealer.


Congratulations! You’ve successfully created a beautiful and weatherproof paper mache mushroom. Feel free to showcase it in your garden or give it as a unique gift. We hope you enjoyed this tutorial.
