4.2 Tiles, Membranes and Other
Finishes
4.2.1 Vinyl
Thin sheet flooring, such as vinyl, needs to have careful
panel preparation to ensure that the panel outlines at the
ring anchor grout do not show through the floor covering
as ridges or hollows.
If vinyl flooring is to be used the panels should be covered
with floor levelling compound as per Method C as
described in Section 3.3.4, page 46.
Once the levelling material is cured, vinyl sheeting can be
directly glued, as for any other floor.
4.2.2 Liquid Applied Membranes
Where a room is to have a liquid applied floor finish,
the panel outlines will be visible unless a floor levelling
compound is used to first flush up the floor. Additionally,
Supercrete Structural Floor Panels do not have a
hard enough surface to be left bare or simply painted in
trafficable areas, without a harder wearing course, such as
Supercoat Deck Shield, see www.supercoat.co.nz.
4.2.3 Torch-On Bituminous Sheeting
In situations where Supercrete Structural Floor Panels
have been used to form a deck or roof surface, bituminous
sheeting can be used as a waterproofing surface treatment.
These sheets are supplied in rolls and are applied by heating
the underside with a gas torch until melted and pressure
sticking the heated sheet directly to the substrate.

4.2.4 Directly Glued Rubber
0.69
Butyl type rubber membranes, such as Butynol can be glued
directly to Supercrete Structural Floor Panels. Surface
patching and levelling of the ring anchor grout may be
necessary to avoid panel outlines showing through.
4.2.5 Timber Decorative Flooring
Timber floor planking and decorative floor parquet or
strip sheeting works best on Supercrete Structural Floor
Panels when mounted on battens. This allows for the timber
expansion and contraction to occur without stressing a
direct stick adhesion. First install ply strips or timber battens
to the floor panels using nylon sleeved screw anchors and
construction adhesive and lay equal thickness of polystyrene
or similar packing between to deaden any drummy noise
potential. Then fix the decorative planking to the battens
as for any other carpentry situation (eg secret nailing of
tongue and groove profile, etc).
4.2.6 Asphalt
Hot mix bitumen impregnated aggregates such as asphalt
can be laid over Supercrete Structural Floor Panels. Be
sure that the mass of the screed thickness has been allowed
for in the load assessment for the selected panels.
4.2.7 Roofing Sheet or Tiles
Where roofing products such as sheet steel, or tiles made
from clay, concrete, slate or pressed metal are to fixed over
Supercrete Structural Floor Panels, these must be fixed
to timber or steel roofing battens which have been screw
fixed to the panels with nylon sleeved anchors, suitable
sized for capacity.
