Extrude the desired amount of the ready-to-use Liner paste from the syringe and spread it out slightly on the mixing pad
using a disposable brush. first, apply the Liner to the cavity walls and cavity floor in a thick coat and precure each
segment for 20 seconds using a Quick curing light. make sure to fully cover all areas, as the Liner provides an essential
bonding surface to the luting composite. do not cover marginal areas at this stage (course of natural enamel).
Generously cover the cavity walls and floor with the 1 st liner cover and precure with Quick for 20 seconds for each segment.
