Installation Instructions

28
NOTE: When staples are used in upholstering carpet on stairs, take
care to separate pile yarns to avoid trapping yarns, resulting in visible
distortion. If the edges are exposed, they must be edge sealed.
Upholstery work needs to have no raw edges exposed. Any seams or
joints must be sealed. Carpet seams need to be split in the direction of
the balusters/spindles.
15.3 Glue-down Installation
Install carpet on stair treads and risers using recommended adhesive. Stairs
without a return (nose) can be installed as one piece over the tread and riser. It is
required that on stairs with a return, carpet be cut and installed with the tread and
riser being separate pieces.
15.4 Carpet Direction
It is recommended that machine direction of the carpet be installed in the length
direction of the stairs.
NOTE: Most manufacturers recommend carpet pile direction run
down the stairs.
16.0 Patterned Carpet Installations
16.1 Uninstalled Patterned Carpet
Carpet is a textile fabric subject to processing variations in the four pattern
conditions: bow, skew/bias, elongation variation and trueness of edge.
Measurement of these four conditions is performed on an uninstalled
breadth/width of carpet. Individual manufacturers have tolerances to which their
patterned products are required to conform. There are no industry standards for
carpet pattern variations.
16.2 Manufacturing Tolerances
Most manufacturers provide established tolerances and specific installation
instructions for their patterned goods.
Factors affecting pattern match on the job site include, but are not limited to:
 method of installation
 condition and levelness of the floor
 type of carpet backing system selected.
Alignment of patterned carpet typically requires the use of mechanical stretching
devices (i.e. power stretcher, mini stretcher, etc.).
