As a preparatory step of the VITA VM LC BASIC layering, VITA VM BOND sold separately and VITA VM LC OPAQUE are previously applied onto the framework. Application of VITAVM®LC OPAQUE: First add liquid into the depression of a black ceramic mixing plate. Then add the powder and stir with a plastic spatula for approx. 30 sec to obtain a homogenous, thin mixture. Mixing ratio: 5 drops of liquid and 1 measuring spoon of powder (to obtain approx. 4 units). The use of a metal spatula is not recommended since it may result in color changes.
