Wallpaper and Wall Coverings
Explains wallpaper as a thin covering entirely dependent on the flatness, soundness and suction of the wall behind it, with the practical consequences at seams, corners and removal.
Educational reference entry. Suitability depends on the complete assembly, substrate, exposure, installation method, manufacturer documentation, local requirements and qualified professional review.
Overview
What wallpaper is
Wallpaper is a decorative covering supplied in rolls and hung to the wall with adhesive. What it is made from varies considerably: traditional paper, paper faced with vinyl, non-woven backings that carry the paste on the wall rather than on the covering, textiles, grasscloth and other natural facings, and heavily embossed papers designed to be painted afterwards.
The covering is thin, so it follows the wall rather than correcting it. Hollows, ridges, patched repairs and joint lines all read through. Where a wall is doubtful, lining paper is the traditional intermediate layer, and where suction is uneven the wall is normally sized or sealed first so the paste behaves consistently across the room.
Practical differences between types show up at hanging and at removal. Non-woven materials are generally designed to strip dry in whole lengths; older paper types are not. Pattern repeat, whether a design must be matched across seams, and whether the covering is washable all belong to the specific product's documentation rather than to wallpaper as a category.
Terminology
Common names and aliases
These names describe the same thing. The library keeps one entry per material so that an acronym, a trade name or a regional spelling never becomes a second, thinner page.

Applications
Common applications
Where this material is typically encountered. A typical application is not a statement that it suits your project.
- Feature walls in bedrooms, dining rooms and living rooms where pattern is wanted.
- Full-room decoration where a pattern or texture carries the whole scheme.
- Lining paper over older walls to give a more even base for painting.
- Hallways and stairwells where a covering adds depth to a tall space.
- Panelled or dado-height areas where the covering sits above or below a rail.
- Ceilings, where paper is occasionally used to unify an uneven surface.
Consideration
Where it is commonly considered
- On sound, flat, dry walls that have been prepared and sized appropriately.
- Where a pattern, texture or scale of design cannot be achieved with paint.
- Where redecoration is expected and the owner accepts eventual stripping.
- Over lining paper on older walls that are sound but not especially even.
Professional review
Where additional professional review is especially important
These are the situations where the answer depends on the specific building, and where a qualified professional should be involved before anything is decided.
- On walls where damp or condensation has been observed but not investigated.
- In shower enclosures and other zones where water contacts the wall directly.
- On friable, powdery or previously distempered surfaces without preparation advice.
- Where the wall moves or cracks, since seams will open at the same places.
- On unsealed surfaces where suction is high and uneven across the wall.
Properties
Key properties to discuss
Qualitative topics worth raising. Measured values, classes and grades come from the manufacturer's technical documentation for the specific product, not from a reference page.
- Substrate dependency
- The covering telegraphs the wall. Anything you can feel with a hand run across the surface will usually be visible once a covering is hung and the wall is lit from the side.
- Moisture behaviour
- Adhesive is water-based and the wall's absorbency governs how it grips and how long it stays workable. Persistent damp behind a covering tends to show up as lifting seams and staining.
- Appearance
- Pattern scale, repeat and whether the design must be matched at seams determine how the room reads and how much material the job needs, which is a supplier conversation rather than a guess.
- Repairability
- Local repair is difficult because a patch rarely matches an aged sheet in colour. Keeping a spare roll from the same batch is the practical safeguard against that problem.
- Maintenance
- Cleanability varies enormously between paper, vinyl-faced and natural facings. What a particular covering tolerates is stated by its own documentation, not by the category as a whole.
- Installation dependency
- Seams, corners and openings are where hanging quality shows. Walls are rarely square or plumb, so where the first length is set out affects how the pattern falls right around the room.
- Surface wear
- In circulation routes and at hand height, coverings scuff and mark. Textiles and natural facings are generally less tolerant of contact than vinyl-faced products are.
Exposure
Exposure and environmental conditions
- Is this wall dry, and is there any history of condensation on it?
- Will steam or splashing reach the covering during normal use of the room?
- Is the room heated and ventilated in a reasonably settled way across the seasons?
- Does this wall run cold because it sits on an external elevation?
- Are radiators or heat sources close enough to affect the covering?
Assembly
Substrate and system dependencies
What this material sits on, is fixed to or depends on. This is usually where performance is won or lost.
- The wall must be flat, sound and free from loose or powdery material.
- Suction is normally evened out before hanging so the adhesive behaves consistently.
- Lining paper is the traditional route on walls that are sound but uneven.
- Newly plastered walls need to reach a settled condition before a covering goes on.
- Fresh patch repairs create local differences that a thin covering will reveal.
Appearance
Appearance and finish considerations
- Pattern scale reads completely differently on a sample sheet and on a whole wall.
- Where the pattern lands at ceilings, corners and openings is a design decision.
- Batch variation is real, so all rolls for a room should come from one batch.
- Seams remain visible under raking light on almost any covering, however well hung.
- Textured and natural facings vary within a roll, which is part of their character.
- Adjacent painted surfaces need a colour decision taken with the covering in hand.
Durability
Durability questions
Questions to raise rather than a service life to expect. No material has a universal lifespan — it depends on the assembly, the exposure and the upkeep.
- How much contact will the covering take in this particular room?
- Is the covering washable, and to what extent does its documentation say so?
- Will sunlight fall directly on the wall and affect the colours over time?
- Is the wall behind stable, or are seams likely to open at existing cracks?
- Is a spare roll from the same batch being kept for future repairs?
Upkeep
Maintenance and repair considerations
- How should marks be cleaned without damaging the surface of the covering?
- Can a damaged length be replaced, or would the whole wall be redone?
- Is the batch reference recorded with the rest of the handover information?
- What is involved in stripping this covering when the room is next changed?
- Are seams likely to need attention, and who would do that work?
Installation
Installation dependencies
What the installation depends on — not how to do it. Method belongs to the manufacturer's instructions and the trades carrying out the work.
- The wall is prepared, sized or sealed before any length is hung.
- Setting out the first length governs where the pattern falls around the room.
- Corners are rarely plumb, so lengths are usually cut and lapped deliberately.
- Switch plates, sockets and radiators need to be dealt with before hanging.
- Room conditions while the adhesive dries affect seams and edges.
- Whether the paste goes on the wall or on the covering depends on the product type.
Documentation
Documentation to request
Ask for these in writing, for the specific product being proposed, and keep them with the project record.
- The product data sheet, including pattern repeat and matching requirements.
- The batch reference for all rolls supplied for a given room.
- Cleaning and care guidance specific to the covering that was supplied.
- Adhesive recommendations issued by the covering's own manufacturer.
- Removal guidance, so that the next redecoration is not an unwelcome surprise.
Conversations
Questions for qualified professionals
Bring these to the relevant qualified professional, manufacturer or authority. Requirements vary by project and location.
- What condition is the wall in, and does it need lining first?
- Does this wall need sizing or sealing before any covering is hung?
- Where will the first length be set out, and what decides that position?
- How will the pattern be handled at corners and around openings?
- How much extra material does the repeat require for this room?
- Is this covering suited to the humidity in this particular room?
- How would this covering be removed when the room is next redecorated?
- Has the wall been checked for damp before the covering was chosen?
Blind spots
Commonly overlooked points
- The covering hides nothing; it follows the wall and shows whatever the wall does.
- Mixing batches within a room produces a colour step that is obvious once lit.
- Removal is part of the decision, and some coverings are far harder to strip than others.
- The extra material a large pattern repeat needs is often underestimated when quantities are worked out.
- Seams tend to open first where the wall behind moves, not where the covering is weak.
What this page does not do
- Lifting seams or staining behind a covering can indicate a wall problem that a qualified professional should investigate.
- Cleanability, water tolerance and removal characteristics vary by product and belong to its own documentation.
- No hanging, pasting or drying guidance is given here; that is the decorator's and the manufacturer's territory.
- Build Design Hub publishes this reference for education and does not test or endorse any covering.
