We had some damp proofing work done to a dwarf wall in our 18th century timber framed cottage just before Christmas. This involved stripping away the old plaster, injecting the chemical treatment then applying a waterproof plaster.
This was nearly two months ago and although most of the plaster has changed to a light pink colour there are still patches that are darker.
Do I need to call out the contractors or is this normal?
