Double Carpet Bond Installation GUIDELINES & PROCEDURES
INTRODUCTION TO DOUBLE BOND Roberts Consolidated Industries is proud to be the pioneer of the Double Bond carpet installation method. Over the years, the procedure for Double Bond carpet installations has evolved, and this manual was developed to provide the most up-to-date, comprehensive set of guidelines and procedures. Once mastered, these techniques will make Double Bond as easy as direct bond installations…with higher quality results.
CUSHION REQUIREMENTS The cushion in a Double Bond installation is subjected to much more stress than a conventional stretch-in cushion. It is stressed not only vertically but also laterally because it is glued top and bottom. The density and integrity of the cushion must be such that it can withstand the additional stress. Further, the top and bottom of the cushion must be both practical and suitable for bonding with trowelable latex based adhesives.
Carpet-to-Cushion Notes: • Woven carpet should be rolled again 3–10 hours after the initial rolling. • Eliminate any bubbles by pressing straight down prior to full adhesive set up time. Do not roll bubbles to edge. • Due to dimensional instability, Double Bond installation of carpet with a unitary backing is not recommended. • Never use a roller heavier than 35 lbs.
