Damp issue

Hi guys and girls.
I have a damp issue in my house, I don’t really ever get involved with the damp proofing side of things so I’m aa little lost on how to fix the problem. It’s an internal wall but I do have a cellar below so presuming the damps rising from there. Would hacking off 1m high and S&C render and then skim it solve the issue?
Thanks in advance

S/c dams and hides the issue.

to be honest I’m not sure what’s causing this myself. Damp can be tricky. I like limelite because it’s breathable.
 
Is this in a kitchen?
Yea it’s in the kitchen... it’s weird, it’s the only part of the house where this is happening and I’m totally lost for why. Wall feels dry to touch apart from one bit which looks damp. Thought maybe it was a salt issue but I’m not sure anymore.

Just going off what chrispy said. Hot and cold is rife in a kitchen. What’s behind it? Is that a cupboard?

Nothing is behind it, its a wall that’s on show nowhere near any appliances. It’s a bit of wall in between the door to get in the kitchen and the door that goes down to the cellar.
 
If you're going s + c route.

Hack, depending on height (in house), then may or may not inject (dependent)

Seal once and Slurry (x3)

Either
1 - sika 1 render or equiv (w'proof admixture)
Or
2 - limelite or dryzone renovate (pre bagged)

Skim,
Most use normal finish on the render, but dryzone and others do a skim made for damp ££££

How you do it will depend on substrate and how the damp is getting there though. Should become clearer after the hack.

Brilliant thank you for your help. I will hack off 1m high and limelite
 
I've just done my place, belt and braces , hack off 1m, drill and inject, tanking slurry 2 coats, SBR and cement prime and cement render 2 coats with waterproofing salt inhibiting additive skim with multi or dab boards and skim

Do you think this injection works?

Used cream and all sorts of liquids, lots of brands and variants over the years.

Done correctly, yes mate.
You can often see the damp disperse over the course of days in bad cases and a couple of weeks in others. It does create a barrier, depending on the product some are far more effective than others.

Damp will disappear naturally when sand cement comes off
