Please follow the next steps

Sandblast the restoration surface using aluminium oxide powder (30-50 μm) and applying a pressure of 0.1-0.4 MPa (1-4 kg/cm², 15-58 psi). Thereafter, clean the restoration for two minutes in an ultrasonic bath and then dry it using an air flow.

Apply CLEARFIL™ CERAMIC PRIMER PLUS to the restoration surface using an application brush. There is no need to wait for the product to act. Dry the entire surface using a mild oil-free air flow.

Apply phosphoric acid (e.g. K-ETCHANT GEL) to the enamel and let it act for 10 seconds. Thereafter, rinse and dry.

Apply Tooth Primer to the element using an application brush and let it act for 20 seconds. Remove the excess Tooth Primer. Dry the surface using a mild oil-free air flow.

Apply the cement to the restoration surface and place the restoration.

Remove the excess cement using method A or B:
A. Polymerise 3 to 5 seconds and remove the excess.
OR
B. Remove the excess using a small brush. Polymerise the edges according to table 1. Take care: always apply method B for opaque restorations and for opaque colours.

Ensure chemical curing according to table 2.
