Need to clad a section of unsightly wall and hide water damage. Needs to be clad on batons on wall but put into door reveal without batons. Clad up to where red line is from ceiling to floor and butt up to blinds on the left Does this seem feasible?
look up upvc T&G cladding will give you the resistance to stain coming through i assume you want and treatment free surface matching i assume a white upvc ??
if not get back for wood advice

if the damp is there and you dont cure the problem it will build up until it shows its self up elsewhere on the new surface 'drip down to the floor and appear there or mold or fungal growth as it cant dry out
The OP's proposition, & some of the replies border on nonsense.
You dont paint over ongoing damp penetration - personally, I wouldn't paint over any kind of damp signs.
Pulling out that patch of the wall with battens is absurd - it will be weirdly obvious ( to any surveyor or house buyer) & create a possible condition for future dry rot.
You find the cause & fix it - not cause more problems.
OP, why not post pics of the outside shed roof abutment or verge, & the gutter?
Also, why not shift the unit and the blind, and take more pics esp of the brickwork below the window board?
Respectfully to the OP, he's been appointed to hide the damp patch, not find the cause, for sure it's wrong and one would hope he's written to his customer advising against such a dastardly plan, if they're still keen to push forward then so be it. Perhaps the customer is a dodgy landlord.
