Installation Standard
Generally Pedigree Carpets are installed to AS/NZS 2455.1: 2007. In cases where the
carpet has an impervious backing - example "Pedigree Smokey" - then the subfl oor
should be prepared to AS 1884 : 2012 or NZ 1884 : 2013 ensuring that the substrate is
sui ciently absorbent to allow the adhesive to disperse in order to tack-up and cure.
Prescribed Adhesives
Indoor Use: Only use Karndean Fibre-Bond adhesive. This is a strong water
based co-polymer adhesive which is solvent free and low odour.
Outdoor use: Only use Karndean Fibre-Bond UV adhesive. This is an outdoor
all-weather waterproof and heat resistant solvent based adhesive which is
classed as "fl ammable". It will bond securely to cured concrete, asphalt, exterior
grade timber and other clean, smooth, level paved surfaces.
Sub Floor Requirements
Subfl oors must generally be permanently dry, smooth, level, clean and
constructed to provide a fi rm foundation.
Concrete: Uneven concrete fl oors must be overlayed with a self-leveling
compound and a damp proof membrane must be incorporated. Dampness
tests must be made and a newly poured concrete slab should be to a handtrowel
fi nish with sui cient absorbency for the adhesive to disperse and must be
allowed to become completely dry.
Timber/Floorboards: These must be fi rm, smooth and even. All timber fl oors
must be completely overlaid with fl ooring grade hardboard ("Maisonite" or
similar) to AS2458.
Particleboard, Plywood and Chipboard: These types of substrate must be covered
with fl ooring grade hardboard (''Masonite'' or similar or plywood) in order to
eliminate later potential movement.
MDF: "Thinline" or similar. Suitable provided the MDF is a minimum of 6mm
thickness and sanded to remove the hardened surface and then primed
("Polymer GS400" or similar) thus making the MDF sui ciently absorbent for the
adhesive to disperse.
Cement Sheet: Suitable provided the sheets are fi rst primed ("Polymer GS400"
or similar) because this type of substrate is highly absorbent and has the
potential to disperse most of the spread adhesive.
Directions for use
• Dusty or highly absorbent fl oors must be initially primed with an acrylic primer
("Polymer GS400" or similar)
