The tiles adjoining the profile must be chamfered by 45°.
When creating 3 way external corners, always start by inserting the pre-fabricated parts of the corner set into the tile adhesive so that the whole surface is covered. The following work sequence should be observed:
Left corner piece (1 trapezoid perforation),
Right corner piece (2 trapezoid perforations),
Lower corner piece (3 trapezoid perforations),
Next, cut the profiles to the required lengths and work them into position.
