Installation Instructions

11.6 Transition Molding

Refer to Section 5.4

12.0 Direct Glue Down

12.1 Layout

Refer to Section 5.3. Lay out the carpet according to the seaming diagram. Where

applicable, allow for pattern repeat. Dry lay and align all carpet breadths/widths to

their proper position; and then trim seams.

12.2 Floor Adhesive Application

12.2.1 Trowel Selection

Select the appropriate adhesive and trowel notch configuration recommended

by the carpet manufacturer and/or adhesive supplier, or refer to the general

minimum guidelines in Table II.

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 Section 12.5.

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 Section 12.7.2
