Brief recommendations on working with forms:
- Lubricate the molds (with a very small amount of grease, literally rub for gloss) before casting. Use special greases or you can use a mixture of dies. fuel and engine oil 50/50 or lubricated with petroleum jelly. - For casting plaster 1.8-2 kg per 1 liter of water, for economy, you can also use sea or river sand up to 50% of the mass of gypsum. - For casting cement-sand mortars 1 part of cement + 2.5-3 parts of sand (+ 2.5 parts of aggregate (crushed stone, screening), for tiles more than 2 cm thick), 50 g of plasticizer per 10 kg of cement, 4.5 liters of water per 10 kg of mixture.
