This coving is 127mm, which is the dimension over the outside corners ! What this means is that it sticks out 83mm from the wall and 83mm down from the ceiling. If you have chosen 90mm coving, the dimensions are 63mm.
I use ready made tile adhesive, and hold the coving in place with a few temporary panel pins in the wall and ceiling placed against the long edges, (NOT through the coving). Once the adhesive has set, remove the pins.
