  2. Apply Primer FD if necessary and allow to dry.
  3. Cut the cartridge nozzle at a 45° angle to the required joint size.
  4. Extrude the sealant using a suitable gun and smooth the surface with a moistened tool before a film forms.
  5. Allow the sealant to crosslink fully, which depends on humidity and temperature.
