Coving uneven ceiling

[andywhy]

hi, not sure if this is in the right section but here goes

Looking to fit plaster coving in a bedroom of quite an old cottage. Although the ceilings are generally nowhere perfectly level/straight, there is one major hump in the ceiling about 18 inches long by 2 inches high at its maximum.

How should I go about tackling this. Thinking of just filling this gap with a vertical edge (i.e. extending the lip of the coving). Does this make sense?? Is coving adhesive/filler suitable for such a large gap??

or..is there another solution

thanks

Andy

I dont use coving adhesive (too 'sticky' - dries too quickly too!)I always stick it up with Artex, this will fill the top gap too when mixed 'stiff' ..Works every time for me
