A decision you can check
- 01
Define room exposure
Record moisture, grease, sunlight, abrasion and cleaning needs. Bathrooms still need ventilation and a wall system suitable for the environment.
- 02
Inspect the surface
Texture, repairs, gloss and colour variation can telegraph through thin material. Plan lining paper or skim work where appropriate.
- 03
Match adhesive and primer
Use the wallcovering manufacturer's approved paste and a compatible wallcovering primer, not leftover paint as an assumed substitute.
- 04
Approve a hanging sample
Inspect colour, seam visibility, motif scale and cleaning on the actual wall before cutting the full order.
Write a specification someone else can check
Heavier or more washable does not automatically mean suitable over a damp wall.
Dark backgrounds and light substrates can show at seams without compatible preparation.
- Define room exposure
- Inspect the surface
- Match adhesive and primer
- Approve a hanging sample
Convert the decision into quantities
Enter the measured geometry in the Wallpaper Calculator, replace defaults with the selected product coverage and round only at the final purchasable unit. List accessories and preparation materials separately so a coverage change does not silently scale unrelated items.
Commercial wallcoverings may have performance requirements beyond residential washability.
Verify at order and delivery
Check the exact local designation or product code, performance class, size, colour or batch where relevant, stated coverage, yield, density or capacity, ordered quantity and accessory compatibility on the written order. Inspect delivered wallcovering system before installation and isolate damaged or mismatched material while return and replacement options remain open.
What usually throws the order off
- Choosing adhesive type as the only criterion
- Applying over textured or weak paint
- Assuming removable means damage-free on every wall
- Ignoring repeat when comparing roll prices
Frequently asked questions
What must the wallcovering system specification identify?
Make the scope checkable against these decisions: define room exposure; inspect the surface; match adhesive and primer; approve a hanging sample. Record the exact local designation or product, performance class, dimensions, finish where relevant, accessories and controlling technical document.
Which calculator default changes after product selection?
Replace whichever default the exact wallcovering system controls—coverage, yield, density, dimensions, package quantity or capacity—while keeping the verified project geometry unchanged.
Who should approve a substitution?
The owner and responsible designer or installer should confirm in writing that the substituted wallcovering system preserves required performance, appearance, compatibility, installation method and documented supplier or project acceptance criteria.
