PORCELAIN®CASTING POWDER PREMIUM WHITE, 1 kg

White porcelain powder, extremely hard, for filling molds. Mixing ratio: 3.3 parts Powder: 1 part water. It dries quickly, releases easily from molds and is solid. When dry, the objects have a porcelain effect and can be easily painted. It air dries in approximately 30 minutes. Full hardening is achieved in 12-24 hours, depending on the humidity and temperature of the room. For this reason, after mixing it must be poured into the mold quickly. It is non-toxic and non-harmful. During curing, a temperature (exothermic reaction) of 30-40ºC develops which then drops very quickly. You can first spray the mold with a layer of Rubbing Spray to prevent bubbles from getting trapped and then fill the mold.
