Broadloom Carpet

12.2.2

Adhesive Application

Spread floor adhesive uniformly over the substrate with an appropriate trowel, leaving

ridges of sufficient height to achieve full and complete coverage of both the substrate and

carpet backing. Trowel notches wear down during use. Replace trowel as necessary to

maintain proper spread rate. After sufficient open time, press carpet into the adhesive and

roll with an appropriate roller as specified in the Broadloom Carpet > Direct Glue Down >

Rolling section of this document.

NOTE: Bond failure most often is caused by:

· inadequate adhesive application from incorrect trowel notch size and/or trowel notch

configuration,

· wear or improper trowel angle during application

· improper type and grade of adhesive

· incorrect open time and/or working times

· bond breakers or substrate contaminants such as, but not limited to, residual curing

and parting compounds

· pH and moisture-related problems

· lack of protection

· premature traffic or cleaning before adhesives have adequately cured

· lack of protection, Refer to Broadloom Carpet > Direct Glue Down > Post Installation

> Materials for Protection section of this document for more information

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.
