Before actual jointing, fill any accidental gaps between boards and any other areas (spalls, deterioration of the surface etc.).
Apply manually by «buttering» the mitred-edge using a 10 or 15 cm plaster spatula and then ad- ding the tape (milled face against the jointing coa- ting).
Then add a finishing coat, allow to dry and finish to hide the tape. Also hide the screw heads.
For projecting vertical edges, use reinforced tape (reinforcing face on board side).
Apply a tape band on the inside ceiling edges ensuring that the concrete is free of any trace of formwork oil.
The substrate must be dry and free of any powdery or insufficiently adhesive product.

A repeat coat can be made 24 to 48 hours after application of the first coat, depending on the ambient conditions.
