A wallcovering specification is evaluated on the day it is installed and again several years later, when the wall has absorbed everything the building does to it. The second evaluation is the one that determines whether the material was specified correctly. Considering how Momentum wallcovering will age means examining the conditions that act on a wall surface over time.
The Forces That Act on a Wall
Aging is not a single process. Several separate mechanisms operate on a wallcovering, and they act on different parts of the material.
- Abrasion from contact with hands, carts, luggage, and equipment, concentrated at specific heights
- Cleaning wear from repeated washing or scrubbing, acting on the surface layer
- Light exposure, which acts on the printed color over long periods
- Moisture, which acts at seams and behind the material
- Impact, which acts in narrow bands where equipment makes contact
A wall does not experience these evenly. The lower portion of a corridor absorbs impact and abrasion. A daylit lobby absorbs light exposure. A restroom absorbs moisture. The specification question is which forces apply to which wall, and at what height.
Identifying them individually keeps the specification tied to the conditions present rather than to a general expectation of durability. A wall that receives no cart contact and little daylight is aging under a different set of inputs than one in a service corridor.

Durability Class and Construction
Commercial wallcoverings are classified by weight per linear yard, and that weight reflects construction.
- Type I is approximately 15 ounces and is used in lower- and mid-traffic spaces.
- Type II is approximately 20 ounces and is the class most commonly specified across commercial projects.
- Type III is approximately 33 ounces and is manufactured for high-impact environments.
The scrub rating, documented by the manufacturer, describes how the surface responds to repeated cleaning. Reading the weight class and the scrub rating together gives a picture of how the material is built to respond to the forces above. These are documented manufacturer figures, available on the product data sheet, and they describe tested behavior rather than projected service life.
Seams Over Time
Seams are where a wallcovering installation is most exposed. They carry installation tension, they are a path for moisture, and they receive concentrated mechanical contact during cleaning. A specification that accounts for aging accounts for how seams are positioned relative to the traffic and cleaning patterns of the space.
The 54-inch width of contract goods reduces the number of seams across a given wall. Fewer seams means fewer points where the forces above concentrate, and fewer edges exposed to cleaning contact and moisture over the life of the installation.
Light and Color
Printed color changes under prolonged light exposure. This process operates slowly and unevenly, which is why it becomes visible where furniture has shielded part of a wall or where daylight reaches one section more than another.
Specifying for a daylit space involves confirming what the manufacturer documents about lightfastness for a given pattern and colorway. Placement matters as well, since the same material will age differently on a north-facing wall than on one receiving direct afternoon sun.
Wall Protection as Part of the Specification
Where a wall receives routine impact from carts, equipment, or high-volume foot traffic, wall protection is a separate product category manufactured to absorb that contact. Specifying wall protection in the zones where impact concentrates addresses a force that a surface wallcovering is not constructed to absorb.
This layered approach places each material where it answers the condition present on that wall.
Maintenance as a Specification Input
How a facility maintains a wall shapes how the wall ages. Cleaning frequency, cleaning agents, and mechanical action are known before installation in most commercial buildings. Confirming the scrub rating against the facility’s actual maintenance schedule connects the material to the way the building will be operated.
A specification written with the maintenance plan in view accounts for a variable that would otherwise act on the wall unexamined.
