I’ve had the stairway re-plastered in the house as part of some pretty major building renovations. The plastered has done a good job but having decorated the new plaster and the original stringers (completed about 2 months back) I’m getting a lot of cracking in the paint where the wall meets the stringers.

I finished the gap with caulk before decorating and although the caulk is sound the paint on top is what has cracked, presumably due to movement of the stair case. Should I just re caulk with white and live with it getting a bit grubby or can anyone suggest a way to get a more professional finish?

Thanks,

TC.

when the wall was plastered the stringer probably soaked water and expanded and over time has shrunk, i would just refill it then sand it and touch it up.

You can never fill this gap with hard filler as this will continually crack with the spring of the stairs. What i do is use a small wooded bead about haly inch and stick it to the wall following the stringing but not glued to it. The stairs will continue to flex but as the bead is stuck to the wall and not the timber it will not move. You will have a slight gap under the bead as it touches the string but at least this will always be staight.

robbie uk has the right answer for you...but ive recently found a new way of sorting this prob out. if the crack is really thin then a small quad bead will do, but if its a real big crack that (if you dont mind doing a bit of work) then rake out all the old caulk and scrape a bit of the plaster as well and fill the big gap first with grip fix or some other really strong glue. once set then finish with caulk.

If you're sure its the paint thats cracked ontop of the caulk, this can be remedied by gettin some solvent based undercoat, thin with white spirit, then apply sparingly along the cracked /crackled area. Dont apply too thick and be sure to feather in to blend so you dont get any thick lines showing. Allow to dry fully overnight if poss. then touch in over the undercoat with your emulsion let this dry, you'll hopefully notice that crackle has gone. then if needed coat up overall.
Matt paint sometimes does this on caulk, it's when it dries, the matt coat is not elastic enough and the surface tension differs and when it all dries >>.crackles.. or somthing like that :)

Good luck.
