Gluing the Cushion to the Floor
Pressure Sensitive Adhesive or Premium Multi-Purpose:
• Once all of the cushion for an area has been laid out and trimmed, in one section at a time the
cushion should be folded back and adhesive applied to the floor. Special attention should be given
to spreading the adhesive adjacent to the walls (cut-in) to prevent edge curling. The adhesive
should be applied with a notched trowel according to the adhesive manufacturer’s recommendations.
It is not recommended to apply the adhesive with a paint roller due to the potential of inconsistent
application. To ensure sufficient bond of the adhesive, the cushion should be laid into the adhesive
while in a “tacky wet” condition. For pressure sensitive adhesives, this point is often identified when
the adhesive turns clear from its original opaque appearance. Smooth the cushion into the adhesive
working toward the seams. Eliminate any bubbles or wrinkles and make sure that the seams meet without
tightness, compression, or overlap. A 2” wide moisture resistant tape such as duct tape should be used on
all cushion seams to ensure seam integrity and to avoid telegraphing through to the carpet face.
Carpet Layout
• After the cushion has been secured, cut the carpet to the proper length and spread out in the area
to be carpeted. The carpet should be cut 3-4 inches (75-100 mm) longer than the area
measurement. Where applicable, allow for pattern repeat. Carpet seams should be at a right
angle to cushion seams or offset at least 6 inches (150mm) to either side. Align all carpet breadths
to their proper position and trim seams. Care must be taken to avoid cutting into the cushion under
the seam.
Gluing Carpet to Cushion – Premium Multi-Purpose Adhesive
NOTE: It is imperative that premium multi-purpose adhesive formulated specifically for double-glue
installation be applied using manufacturer recommended trowel notch size and shape.
• The floor adhesive must be spread uniformly over the cushion with an appropriate trowel, leaving
ridges of sufficient height to achieve full and complete coverage of the substrate and carpet
backing, including penetration into the backing’s deepest recesses.
• Test Area: Confirm amount and placement of adhesive by installing a small area, then lifting the
carpet, noting adhesive transfer and coverage into backstitch of carpet. If insufficient coverage
is seen increase notch size and recheck.
• Once adhesive has been spread for a given section follow adhesive manufacturer’s recom-
