Installation Standard
Generally Pedigree Entrance Zone is installed to AS/NZS 2455.1:2007, however
sight should not be lost that the carpet has an impervious backing and will not
allow vapour to 'breathe' though the pile. When in doubt prepare the subfl oor
to AS 1884 - 2012 (or for New Zealand NZS/AS 1884 - 2013) ensuring that the
substrate is sui ciently absorbent to allow the adhesive to disperse in order to
tack-up and cure.
Prescribed Adhesive
Only use Karndean Mega-Bond adhesive. This is a strong bond water based copolymer adhesive incorporating
a polymer sealer and is solvent free and low odour.
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 hand-trowel 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 ("Maisonite" 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 spreadadhesive.
Directions for use
• Dusty or highly absorbent fl oors must be initially primed with an acrylic primer
("Polymer GS400" or similar).Textile installation guide
