I'm looking for a skilled tradesperson to prepare, plaster, and finish a wall in my home. The job involves patching small cracks, applying plaster skim coat, and ensuring a smooth, paint-ready surface. I have standard materials available and just need the expert workmanship. It would be great if you can assess moisture or any underlying issues and advise on primer and sealing if necessary. I'm aiming for a clean, even finish on a wall of roughly 8–10 square meters. Please share your availability and any preparation tips you suggest before you start.
