I wouldnt say coving adhesive is particularly expensive.. unless youre doing hundreds of metres but even then, nope, not expensive!
supa cove is the future! never use anything ready mixed as it dont go off quik enough! i want to take the nails out and get paid! lol
Use lafarge or knauf board adhesive. Gyproc board addy is the devil
horses for corses mate the way i was taught was to strike a line pin 4 nails per length into the wall on the strike line then maesure, cut and stick, and cos its only 4 nails per length by time youve got to the end of the room youll no doubt have a little bit of mix left the nails come out and the tiny little pin holes get filled in 5 mins
We use board addy, had the gyproc cove addy fail on us to many times
