12.2.3 Open/Tack Time
Appropriate open time varies depending upon environmental conditions,
substrate porosity, backing system and adhesive type. Refer to the adhesive
and/or carpet manufacturer for requirements regarding open/tack time.
12.2.4 Working Time
Working time (also referred to as slip time) is the length of time after covering
the adhesive with carpet to make adjustments or manipulate the carpet
without negatively impacting the permanent bond.
12.3 Alternative Adhesive Systems
Alternative field-applied systems, such as but not limited to spray adhesive or roll-
adhesive films, are available. Refer to carpet manufacturer information whether an
adhesive system is acceptable.
12.4 Seam Sealing
Refer to Section 10.2.2
12.5 Rolling
After the required amount of adhesive has been applied to the floor and the
prescribed open time has been allowed, the carpet is carefully placed into the
adhesive. To insure an adequate bond, it is then required that the carpet be
uniformly pressed into the adhesive using a roller designed for this purpose.
Rolling should be performed with the lightest roller that will cause the adhesive
ridge pattern to transfer to the back of the carpet while still leaving the adhesive
bonded to the floor. Do not exceed 75 lbs. unless specifically directed by the
manufacturer. Roll the carpet in both length and width directions.
NOTE: In some circumstances, re-rolling is required as well as the
placement of weights in problematic areas.
12.6 Finishing at Wall Line
Finish the installation along the wall line leaving a net, smooth, neat, and secure fit.
12.7 Post Installation
12.7.1 Curing Adhesives
It is recommended that traffic over field-applied adhesive installations be
restricted to installation personnel only for a minimum of 24-48 hours to allow
adhesives to cure properly. Premature traffic will cause installation failure.
