In this tutorial, Peter Plan made a wood carving Fenris from Norse Mythology. Below is his tutorial on how he made a Latex Mold out of it. 

Step 1. Coat the carving with a wood sealer. This will stop the Latex from soaking into the wood.

Step2. Use a quality latex.

Step3. Pour the latex on to the carving.

Step4. Smooth the latex over the Mold.

Step 5. Make sure any bubbles are removed.

Step 6. Ensure the latex covers all of the carving. For strength this process can be repeated with additional coats of latex, even adding surgical bandage between layers. Wait until latex is dry before adding additional latex.

Step 7. Wait until latex is completely dry.

Step 8. Gently and slowly remove the Latex Mold from the carving starting on the edges first. Be very careful not to tear it.

Note that the Original Wood Carving is left darker from the Latex. It is advised to practice first and not to use antique furniture.

Begin making your Plaster Cast. 

Step 9. Mix Plaster of Paris according to manufacturers instructions.

Step 10. Pour plaster gently into your newly made mold ensuring it is completed in one go, or the plaster may dry at different times and crack when dry. If the plaster cast is to be used as a wall hanging or pendant it is at this stage a loop of wire can be placed in the wet plaster.

Step 11. Smooth out all the bubbles and leave to dry on something solid.

Step 12. When plaster is dry, carefully peel away latex mold.

Your Cast is Now Ready for Painting. 🙂
