Paper mache can be used to cover plastic objects, but it does not adhere easily. To improve adhesion, one can roughen the plastic surface and use a thick paste. Paper mache can also be used as a mould for plastic objects. For instance, one can wrap a plastic bowl in tin foil and place polymer clay over it to create a 3D shape. Similarly, plastic objects can be wrapped in cling film and taped to create a smooth surface for paper mache.

What You'll Learn
Paper mache clay can be used to sculpt whole forms or add details to projects
Paper mache clay is a versatile material that can be used in various ways to create sculptures and other art projects. It can be used as a standalone sculpting medium to create whole forms, or it can be combined with traditional paper mache techniques to add details to existing projects.
When using paper mache clay to sculpt whole forms, it is essential to ensure that the clay is well-mixed and has a consistent texture. This can be achieved by blending paper into the paste to create a clay-like substance that can then be moulded into the desired shape. The amount of flour added to the mixture can be adjusted to achieve the desired consistency, with more flour making the clay thicker and easier to sculpt. This type of clay is ideal for sculpting small shapes or figures and can also be used to add texture by pressing it into moulds.
For those who prefer to work with their hands, paper mache clay can be mixed by hand, although it requires significant effort to ensure that the paper fibres are adequately dispersed. Alternatively, a power screwdriver with a paint mixing attachment can be used instead of a hand mixer. It is worth noting that the mixture will be heavy, so a small mixer may not be suitable for large batches.
Paper mache clay can also be used in conjunction with traditional paper mache techniques. For example, it can be applied as a top layer of clay to add details to paper mache sculptures. However, it is crucial to ensure that the paper mache base is completely dry before adding the clay, as wet surfaces can cause separation. Additionally, the paper mache clay recipe can be adjusted to add more flour when creating textured surfaces or sculpting details.
The versatility of paper mache clay extends beyond sculpting, as it can also be used to create unique finishes for art projects. For instance, it can be sanded to create a smooth, beautiful surface or painted and sealed with glue to preserve the artwork. Furthermore, paper mache clay can be combined with other materials, such as tissue paper and PVA glue, to add colour and texture to sculptures, as seen in the creation of a regency-style figure with a bottle green dress.

Paper mache can be used as a mould for replication
Paper mache is a versatile art form that allows you to create a wide range of projects, from bowls and vases to sculptures and masks. One of the benefits of using paper mache is that it can be used as a mould for replication, enabling you to create multiple copies of your desired object.
To use paper mache as a mould, you can start by selecting an object that you want to replicate. This can be anything from a plastic bowl to a styrofoam skull or an acrylic sphere. Once you have your object, you can wrap it in materials such as tin foil, clear tape, or cling film to create a smooth surface. This step is important because it ensures that your paper mache mould will have a precise and detailed shape.
After preparing your object, you can begin building the paper mache mould. Dip strips of newspaper or brown paper into a paper mache mixture, which can be made by combining water and flour or using pre-made mixtures from craft stores. Apply these strips to your prepared object, smoothing them out with a soft, damp brush or your fingers, which can be lightly coated with wood glue to help the paper strips adhere smoothly. You can also use a silicone mould to create your paper mache casting, ensuring that the mould is properly prepared and coated with a release agent, such as talcum powder, for easy removal.
By following these steps, you can create a paper mache mould that captures the intricate details of your original object. Once your paper mache mould is dry, you can carefully remove it from the original object. Now, you have a mould that can be used to replicate your object as many times as you like. Simply fill the mould with your chosen material, such as clay, plaster, or paper mache itself, and allow it to dry before removing your newly created replica.

Paper mache can be used to cover plastic
Another user on Reddit noted that they had success using paper mache over plastic by covering the plastic in cling film first. They then used tape to stick the cling film smoothly to the surface. This method can be used to replicate the shape of the plastic object in paper mache.
When using paper mache over plastic, it is important to use a release agent to easily separate the paper mache from the plastic. Common release agents include aluminium foil, plastic bags, and tape. It is important to note that tape should only be used if the base will be destroyed when removing the paper mache, as it can be difficult to remove the tape from a reusable base.
Additionally, one user on a paper mache forum noted that they did not use a release agent when using paper mache on the inside of a plastic bowl. They found that the paper mache tightened as it dried, making it easy to remove from the bowl.
Overall, while it is possible to use paper mache to cover plastic, it may require some experimentation to find the best method and release agent for the specific project.

Paper mache can be used to cover a plastic doll
If you want to retain the details of the doll, it is recommended to cast a mould of the doll and then coat it in paper mache. This will result in minimal loss of detail. If you cover the doll directly with paper mache, you will lose some details.
When using tissue paper, tear it into strips and then into pieces about an inch in size. Then, go over the area you want to cover with a glue mix using a paintbrush so it's a little wet. Lightly touch the brush to a piece of tissue paper, lay it in place, and paint it down with glue. Do not presoak the tissue paper, or it will fall apart.
If you want to add texture to your doll, you can use newspaper for the first layer of paper mache. Dip the pieces of newspaper into a craft glue solution in water (approximately 1:3). You can also make layers of different colours, which makes it easier to find uncoated areas.
If you want to paint your doll, be aware that the paper will absorb some of the paint, causing it to come loose from the underlying plastic.

Paper mache clay can be stored in an airtight container
However, once paper mache has been used to sculpt an object, it should not be stored in an airtight container. Instead, it should be wrapped in acid-free tissue paper and stored in an acid-free storage box in a closet. This is to prevent condensation, warping, and peeling due to weather and humidity changes.
There are many recipes for paper mache clay, most of which produce similar results. The type of clay can be altered by adjusting the ratios of ingredients. For example, a rougher clay that is good for sculpting is made by hand-mixing, whereas a finer clay that behaves like store-bought clay can be made with an electric mixer.
Paper mache clay is made by first preparing the paper. This involves placing the paper in hot water and pressing it into a measuring cup to obtain about one and a quarter cups of wet paper. The paper is then returned to the hot water and swirled around until all the fibres are separated. Most of the water is then squeezed out, and the paper is mixed with other ingredients such as drywall joint compound and glue. Some recipes also include flour and glycerine.
Paper mache clay can be used in the same way as store-bought clay to sculpt whole forms or add details to projects made out of paper mache strips. It dries hard and strong, even when applied in thin layers of about 1/8". Once dry, painted, and sealed, paper mache sculptures can last for years.
