12.7.2
Materials for Protection
It is recommended that carpet installation be the last trade on any job site. However, if it
is required to protect the finished floor covering from soil or paint, or if additional work is
required to be done after the installation, the carpet should be covered with a non-
staining, breathable building material paper. Protect the installation from rolling traffic by
using sheets of hardboard or plywood in potentially affected areas.
NOTE: Self-adhering plastic films may leave residues that result in rapid soiling after
removal. Do not place plastic sheeting over any carpet installation because it may present
a slip hazard. Most importantly, plastic coverings will trap moisture, retard adhesive curing
and may promote mold growth.
12.7.3
Maintain Temperature
Do not allow the temperature of carpeted areas to fall below 50
o
F (10
o
C), regardless of
the age of the installation.

Double Glue Down
This is an installation method where carpet cushion is first adhered to the substrate, and
the carpet is then adhered to the cushion using the proper adhesives.
13.1
Cushion Layout
Refer to manufacturer’s installation instructions. Install cushion in the longest continuous
lengths possible with consideration to traffic patterns and carpet seam placement. It is
required that cushion seams be at a right angle (90º) to carpet seams or offset at least 6
inches (150 mm). Join cushion seams net without compression, leaving no gaps. Do not
tape or staple cushion seams for double glue down installations.
NOTE: Cushions should be specifically designed for double glue application and should
not exceed 3/8 of an inch in thickness.
13.2
Carpet Layout
Refer to General Requirements > Measuring and Planning > Layout and Trimming section
of this document. Where applicable, allow for pattern repeat. Dry lay and align all carpet
breadths/widths to their proper position; and then trim seams. Take care to avoid cutting
into cushion under seams.
