Second coat of silicone


Once the first layer of silicone has set overnight, I applied a second, thicker layer this morning. This mix was made from 600grams of part B to 18g accelerator and 42g of catalyst. As the parts are usually mixed in the ratio of 10g catalyst or part A to 100g part B, the accelerator makes up one third of the part A quantity. To help apply the mixture to the high points of the sculpt, I used my hands instead of a trowl. By applying the silicone with gloves, I am able to catch more as it drips downwards and help prevent tentacles of dripping silicone. A final layer of silicone is required after this has set before applying the fibreglass jacket.
