Blimy - Castle Farm - you pay someone to decorate
.
We just spent a week putting up alluminium foil paper over our new plaster walls that showed "stains" and patches of salt peter - then an embost paper - then several coats of paint. The paint was a real problem as the alluminium foil prevented moisture from passing into the wall. Bubbles appeared and white spots appeared - hence the need for several coats of paint.
about 4 days labour for a 10x2.5 meter wall and a day for the other 3 walls.
> £400 me thinks. Materials = about 190 € and we did not do the ceiling.
