Wallpaper Installation in Whampoa

Painted walls, yes, after cleaning and priming. Papering over old wallpaper is a false economy — trapped seams telegraph through and moisture can lift both layers. Strip first; installers quote removal as a separate line.

A single feature wall is usually half a day; a full average room takes 1-2 days including prep. Add time for stripping old paper (half to a full day per room), wall repairs, and drying between prep coats.

Look for installers in Whampoa who show seam close-ups in their photos, not just wide room shots — invisible seams and pattern matching at corners are the skill. Ask what papers they specialize in; grasscloth and mural specialists are a different tier from vinyl hangers.

Installers price per roll, per square metre, or per day. Labour usually lands between half and the full cost of the paper itself — and premium papers (grasscloth, murals, wide-width vinyls) cost more to hang because mistakes are expensive. Removal of old paper is always quoted separately.

Yes, with the right product — vinyl and washable papers handle humidity, and some installers seal edges with clear varnish in splash zones. Avoid delicate uncoated papers near cookers and showers. Good extraction/ventilation matters more than the paper choice.

On well-primed interior walls with quality paste, no. The risk is external-facing and bathroom-adjacent walls where 回南天 condensation soaks in — seal those with moisture-resistant primer or choose washable vinyl papers there.
