We have a fairly wide crack which runs along the join between ceiling and wall, then diagnally across a corner of our bathroom. The house was built about 1890. I've looked on the projects page and found some information about using flexible filler called decoraters caulk, but the pictures attached to the advice don't show this product-can you tell me where I can get hold of some please?
Don't know why nooe has answered this one. Any decoratrors merchants or DIY shed is the answer. Try Googling for it. It comes in a tube and you applyint with a sealant gun.
Ceilings and walls often part company. How big is "fairly"? If "fairly" is bigger than a couple of mm then caulk won't do it - you'll just get an unholy mess. You can either cover it up - cove it for example or you'll need to fill it properly.
