Remember! Remember! Be sure to knead for more than 3 minutes, otherwise it will be hard to harden.
The correct use of the universal mud: open the package and knead the two pieces of the universal glue for 3-5 minutes. Note that the two pieces inside the mixture are repeatedly kneaded. The purpose is to fully contact the reaction, and it will automatically harden after 12-18 hours. Do not move during hardening (note). If you are worried about wearing a disposable glove with your hands, be sure to knead for more than 3 minutes, otherwise it will be difficult to harden. More than two colors, the effect is better! !
