Thanks for that guys, it reasures me a bit, heres why i started this post.
The house im on i have taped the joins with sheetrock taping compound, then boxed it with a 10 then 12 using sheetrock total, sanded, then rolled and hand skimmed the walls and ceilings twice, radius 360 hand sanded it all down smooth as glass under twin 500watt halogens.
Painters have done there bit, electricans have fitted out the hallway with wall lights that shine up and down the walls. everything was looking great i was feeling so proud i felt it was my best work i could possiably do.
Anyway this house has concrete floor with water pipes and a big heat pump to heat the water to heat the floor and so on.
They have fired this up and warmed the house up and now in the hallway under the wall light you can see the line of the tape
Devistated would be an under statement, im gutted, your replys have confermed my thought, its shrunk back into the taper, after all that work this happens
We dont use heaters or dehumids here, no one has them and it costs a lot hire.
So how can i get a perfect level 5 finish then, i thought i had it sorted but it needs ages to dry, this house has been built fast, the owners sold there last place and have demanded a date to move in.
The things against me have been the rush, weathers been around 8 degrees which is not to bad, those
wall lights and the wall paint is a little on the shiny side, if it had different lights and a less shiny paint it would look a lot better, but it dosent.
Im plastering and painting out my next house and thankfully its smaller, they are having hanging lights and wall lights and its a house on a hill that gets bombed with sun, i dont want this to happen again
Been at it for 13 years had the add join do this but its been in areas that has not been a concern, these new wall lights are becoming popular, and people are expecting perfect walls more now, its a bit unrealistic givin these things can happen to you.
