Joint crack between underside of stairs and wall

[jonifife]

Hi,

Snags seem to be taking an age to finish.

Some cracks have appeared where we have plasterboarded and skimmed and painted the underside of the new loft stairs and existing plastered masonry wall.

I'm not too worried about the cracks as in places to be expected perhaps. But would like some advice on the best way to fill them for a longish term solution - don't want to be filling every other month

It is generally on the joint line between the board and wall- sometimes bang in the corner but in areas is about 5-10mm off the wall

I am planning to just use wickes powder filler that I mix myself, sand and repaint or is anything more drastic required... no I am not putitng coving up ''

Cheers

just to be clear the cracks are only hairline not 5-10mm but they wander in off the corner by that amount in a random patterrn...

Decorators caulk could be an option as it is flexible but may shrink into the crack slightly.

Decorators caulk could be an option as it is flexible but may shrink into the crack slightly.

Not could be, it is an option. Certainly for any cracks in the corners. Don't put it on too thick though or you may find the caulk starts to crack and you loose the definition of the corner. Use a damp sponge to smooth it in once you have applied it. Try to apply in layers if its easier.

For any cracks that are not directly in the corner I would use filler as you have proposed.

Good luck
