Apply a mixture of epoxy resin A and B to all areas where the adhesive has hardened.

Fill all the gaps with putty. You can sand it down later, but push it in with your fingers so that it is as thin as possible.

As with cleaning the glue, after applying the putty, remove the putty that has come out with a cotton swab moistened with ethanol.

Putty dries faster in summer and takes longer in winter.

The best result to attach each piece firmly is to let the adhesive surface dry to some extent before attaching.

Allow to dry thoroughly for at least 30 minutes.
