PlasterMix

PlasterMix calculates the next batch for the mould on your bench. Enter a mould's volume, choose a recipe, and set a safety margin. PlasterMix calculates the water and powder you need in grams or ounces, along with the working time and demould window. Start the timer and follow the slake, stir, and pour phases. A soft chime and local notifications mark each phase, including when the cast is ready to check. PLAN YOUR POUR Calculate water and powder from mould volume. Add a safety margin from 5% to 20%, or turn it off. Time slake, stir, pour, and the demould window. Save moulds and combine multiple moulds into one pour. Create custom recipes, mark favourites, and set a powder price to estimate material costs in your chosen currency. Review past pours and repeat a batch. Switch between metric and US measurements. Sync your studio library through private iCloud. YOUR STUDIO, YOUR DATA Pours, moulds, recipes, and settings stay in your private iCloud database and sync to other devices using the same Apple ID. No account to create. No ads. No trackers. A NOTE ON RATIOS AND SETTING TIMES Built-in ratios are based on published workshop consistencies and are intended as a starting point. Read the bag, weigh your batch, and use your own judgement. Setting time varies with temperature, water, and mixing technique. PlasterMix is a studio tool and is not affiliated with any plaster manufacturer.
