How to work

The temperature of gypsum and water should be approximately the same - within 15-20oC. The gypsum is added slowly to the entire amount of water and is kept for about 2 minutes to take it. Stir with a mixer, depending on the amount of time the mixer turns and the amount of gypsum (6-12min). It is recommended to stir under vacuum. After mixing, the gypsum temperature must be measured. The matrix is ​​then poured. Its temperature is also measured. When it rises to 6-8 ° C, air is fed to release the pores. Initially, the pressure was 0.5 bar and increased every 30 seconds by 0.5 bar until a pressure of 5 bar was reached when it was held for 30 minutes until the matrix dried. Then wait no less than 12 hours to harden.
