Double Glue Installation Guidelines
Page 2
• As a general guideline, a moisture emission rate of 3 lbs/1000sq. ft./24 hours and a pH between
5 and 9 are acceptable for most carpets. Beyond these limits, the risk of moisture or alkalinity
related problems increases. Although corrective measures may be available if limits are
exceeded, it is important to consult the individual carpet manufacturers to determine the
acceptable limits for particular products and, where necessary, proper corrective measures.
• When planning a double-glue installation, you may confidently select from the list above.
With the great variety of carpets and adhesives available for commercial installations,
confirm that the manufacturers recommend their products for the double-glue method as a
prerequisite to installation. For specific instructions concerning double-glue installation of the
chosen carpet style contact the carpet manufacturer’s installation department.
Site Conditions
• The space in which the carpet is to be installed must have adequate temperature and humidity
control to facilitate proper installation. Beginning 48 hours before the installation and continuing
at least 72 hours following completion of the installation, the temperature must be maintained
between 65º F and 95º F and the relative humidity between 10% and 65%. If installing over
concrete, the slab temperature should not be less than 65º F. during installation and maintained
at a minimum of 55º F at all times following completion of the installation.
Floor Preparation
• The floor should be free of holes and loose tiles or boards. Repairs should be made as
necessary to provide a smooth surface for carpet and cushion installation. The floor should be
dry and dust-free. All contaminants that may prevent good adhesion must be removed. Floors
should be vacuumed, mopped if necessary, and otherwise thoroughly cleaned prior to carpet
installation. Excessive use of water for cleaning is not recommended, though mopping with a
slightly damp mop is useful to remove dust from the floor surface. Tack strip properly spaced
and secured may be used to hold the carpet edges in place. If tack strip is used, Tri-Tack or
architectural tack strip is recommended.
CAUTION: Always allow the cushion to acclimate to room temperature for 12 to 24 hours prior to installation.
Cushion Layout
• The cushion should be laid out in the longest lengths possible so that the cushion seams will run
perpendicular to the carpet seams. If the seams cannot be at right angles to the carpet seams,
the cushion seams should be kept at least 6” from the carpet seams. Cushion seams must
be butted without compression, leaving no gaps. Any excess along the perimeter walls should
be trimmed and fitted.
NOTE: Foundation Carpet Cushion can be adhered fabric side up or fabric side down.
Adhesive Selection
Adhesive selection is one of the most important decisions in any double-glue installation. Healthier
Choice does not recommend any specific adhesive manufacturer or prouct. However we do
provide our products to adhesive manufacturers for qualification of their adhesives with our
products.
Healthier Choice attempts to maintain an up-to-date list of adhesive manufactures that have
qualified their adhesives with the Foundation line of premium double-glue carpet cushion.
