BUTYNOL & EPDM MEMBRANES
ARDEX specialises in high-quality construction materials for substrate preparation, levelling floors,
waterproofing, the fixing of natural stones & ceramic tiles and other surfacing materials. ARDEX offers
innovative products of outstanding quality and optimal environmental friendliness, as well as providing
training and support services for their application. The ARDEX Group comprises of 28 subsidiaries and
some 1,400 employees active in offices and branches in more than 50 countries.
The history of ARDEX can be traced back over 50 years to Witten, Germany where ARDEX Chemie
Gmbh was founded by Herr and Frau Fortmann and Dr. Kraft. Products such as Ardurit Z8 and
Ardur K15 are firmly established as benchmarks for flooring products worldwide.
In December 2001 ARDEX acquired Norcros Building Products (NBP). The latter has a similar
heritage in the Australasian market with Butynol waterproofing membranes, ABA tile adhesives
– renowned for their quality and technical excellence, a reputation built over 30 years. Innovations such
as Abaflex are unique in the market until this day. Other brands offered by NBP include Superflex
under-tile waterproofing systems, Shelter (previously Dunlop) sheet membrane systems and
HydrEpoxy coatings. In 2002 Vibro Products Pty Ltd, manufacturers under licence of ARDEX floor
levelling and adhesives, was acquired and integrated into ARDEX.
These brands, leaders in their respective fields, come together under the ARDEX umbrella, offering you
expert solutions. In addition, sharing of resources and technology within our extensive network enables
us to provide you with a broader range of world benchmarked products and services.
Make ARDEX your single point of contact for all your waterproofing, flooring and tiling needs.

SEAM TAPE PERFORMANCE
Tests on the seam tape bonding method, by an
independent testing laboratory, have shown average
values equivalent to 90% of unwelded material. It is
considered impossible for the test methods used to be
duplicated in normal service ie. 400% elongation.
BUTYNOL PROTECTION
Butynol protects against water, moisture vapour, gases,
sun, ozone, frost, acids, chemicals and bacteria.
BUTYNOL RESISTANCE
Butynol resists tearing, flex cracking, bubbling and
abrasion. It is extremely strong, has a long life and is
versatile.
STAINING OF LIGHT COLOURED BUTYNOL
To avoid staining care must be taken during design
stage to ensure that water running off unpainted treated
timber and some metals (eg copper) do not run over
light coloured Butynol.

and awkward situations. Supplied in 100mm x 5m rolls.
Flashing tape must not be left exposed. A cover strip
of Butynol or detail tape must be applied over flashing
tape to finish.
SUBSTRATE VENTILATION
Substrate ventilation should be used to release moisture
trapped under the Butynol on concrete surfaces.
Substrate ventilators are used in conjunction with vent
tapes. Tapes should be laid in a grid pattern spaced
at 600mm venting to the roof perimeter. On plywood
substrates ventilators are used at the junction of the
ply. Ventilators are not required in most applications
for cavity ventilation - seek advice from an Ardex
Representative. One way substrate ventilators prevent
moisture vapour build up and if required can be installed
every 90 square metres. Not designed to ventilate roof
cavities. (Refer Diagram page 23).
PLYWOOD TREATMENT
To be in accordance with Acceptable Solution E2/AS1
plywood substrate must be treated to H3.2 with
Waterborne CCA treatment and kiln dried after
treatment.
Plywood must not be LOSP treated.
DURABILITY
Butynol when fixed according to Ardex instruction will
meet the NZBC requirements of B2.3.1(b) 15 years.
Refer BRANZ Appraisal Certificate No 436 (2005).

ADHESIVES AND SOLVENTS FOR USE WITH
BUTYNOL
WA98 - The Standard contact brushing, spray
grade and rolling adhesive for fixing to
the substrate and for laps not subject
to periodic ponding.
(Pitch 5° and above)
Seam Primer - A water resistant primer, used with
seam tape for general lap bonding.
Roofs with a pitch of less than 5°, all coloured
membranes and all guttering and areas subjected
to periodic ponding require special lap bonding. All
coloured membranes, irrespective of pitch require
special lap bonding.
Note: Temperature and Humidity
The evaporation of any solvent adhesive system causes
a drop in temperature at the interface. At times of high
humidity this can result in a micro molecular water layer
at the interface which will result in a failure to bond,
falsely attributed to Adhesive failure. Fixing should not
proceed under these circumstances.
NOTES
1. In cases of extreme absorbency, a priming coat of
50/50 WA98 adhesive and solvent may assist water
shedding and absorption. However, a follow up of
full strength adhesive for full bonding should not be
proceeded with under four hours, thus allowing full
evaporation of solvents absorbed into the substrate.
Primers must be time dried not touch dried.
2. As new substrate materials continually appear on
the market, consult Ardex for approval of their use
with Butynol.
3. Where periodic ponding is likely and on roofs with a
slope of less than 5°, Ardex Seam Tape and Seam
Primer must be used on all joints.
4. Black Butynol and roofs with pitch of 5° or greater
and sufcient fall to prevent periodic ponding may
be formed using the sheet bonding adhesive WA98.
All laps must be wiped with WA98 solvent prior to
bonding.
Roofs with a pitch of less than 5°, all coloured
membranes and all guttering and areas subjected
to periodic ponding require special lap bonding.
Refer Acceptable Solution E2/AS1 8.5.5.2a.
All coloured membranes, irrespective of pitch require
special lap bonding.
5. Do not use in temperatures less than 6°C.

8. Laying of Butynol Roong
It is the responsibility of the Applicator to ensure that
the substrate surface to be covered by the Butynol is
in fit and proper condition, suitable for the laying of the
material.
Tape all joins in substrate sheets with 25mm wide
pressure sensitive tape approved by Ardex.
All Butynol sheeting shall be laid out on the roof to
“relax” the sheeting before fixing. A period of at least
20 minutes is usually required. Do not finally position
sheeting with a tension exceeding 2%.
Apply adhesive to the substrate and the underside
of the Butynol rubber sheeting by brush, spray or an
approved type roller at a spreading rate of generally not
less than 2.5 square metres per litre. Leave to tack dry
before bonding the two surfaces together.
Lay sheeting by drawing back halfway either
longitudinally or transversely. Thoroughly roll or work
over the surface of the sheet to exclude all air and to
obtain a full bond.
All Butynol shall be “lap bonded” as detailed below.
Bonding Laps with Ardex Seam Tape and Seam
Primer
Following laying of the Butynol the laps must be
sealed. Roofs with a pitch of less than 5°, all coloured
membranes irrespective of pitch and all guttering and
areas subjected to periodic ponding require special
lap bonding using Ardex seam primer and Ardex seam
tape. Laps with pitch 5° and above (on black Butynol
only) can be sealed using WA98 adhesive. (Lap areas
must be wiped using WA98 solvent prior to applying
adhesive.)
1. The top lap is positioned and the bottom sheet
marked to indicate the edge of the top sheet.
2. The top sheet is folded back.
3. The Ardex Seam Primer is then applied to the
Butynol in the area marked on the bottom sheet and
50mm in from the edge on the top sheet. The Ardex
Seam Primer is applied to the mating surfaces using
a synthetic scrubbing pad. Scrubbing pads should
be replaced as they become dirty. Allow the primer
to become 'dry to the touch'.
4. Position and unroll the 50mm Ardex Seam Tape
along the seam. The edge of the release paper
should be aligned to the mark on the bottom
membrane sheet.
5. Roll the length of the seam with the release paper
still in place.
6. Remove the release paper from the Ardex Seam
Tape by pulling at a 45° angle away from the seam.
Keep the release paper low to the roof surface as it
is removed.
7. Fold into place the primed edge of the top sheet.
8. Roll the completed seam.
9. Tiling Over Butynol
To direct fix tiles to Butynol, ABA Optima two part
adhesive should be used. Ensure the Butynol surface is
clean and dry before applying the adhesive. All laps must
have seam tape.
(Refer Optima page 43)
10. Protection of Laid Butynol Sheeting
The Butynol roofing contractor shall ensure that his fixers
only work on the Butynol roofing with soft sole shoes.
The Butynol roofer shall co-ordinate with the main
contractor who shall ensure that any other trades who
work over the completed roof wear soft sole shoes.
Upon completion of each area the roofer shall get
the main contractor to inspect the area and the main
contractor will sign off that the area was free from any
defects or damage. It is then the responsibility of the
main contractor to ensure the Butynol roofing is in no
way damaged by other trades.
11. Completion
On completion carefully and thoroughly clean off and
remove all scraps and other rubbish from finished
surfaces and leave in tidy order.
12. Extent of Work
Observe the foregoing specification and supply and
lay Butynol rubber sheeting to all roofs, decks, gutters
and flashings as shown and detailed in the Ardex
specification.

LAYING THE BUTYNOL
Before applying the Butynol, it shall be unrolled
for twenty minutes to relieve stresses induced by
manufacture and storage. The Butynol sheet shall be
set out in the exact position in which it will be finally
required and while it is held in place, it shall be folded
back lengthwise to expose half the underside. To the
now exposed underside and the area of roof also left
exposed, apply an even coat of WA98 Adhesive. When
the adhesive has become touch dry, work the sheet
back into its original position avoiding wrinkles and the
inclusion of air bubbles.
Repeat the process with the other half of the sheet and
when completed, roll the whole sheet with hand press
rollers or the like.
When applying the next sheet, it shall be lapped over
the first sheet by 50mm. All turn ups and downs shall
be neatly formed and cut to a straight line if required.
Butynol shall not be laid under tension.
When the whole area has been covered or as work
progresses, the applicator has to seal the laps.
BUTYNOL LAYING METHOD
STEP 1
Accurately place sheet. Mark spacing with chalk line.
STEP 2
Fold back half sheet. Apply adhesive to both faces.
LAYING SPECIFICATION
The Sub contractor for the work called for in this trade
will be a Company or Person approved by Ardex.
The approved Applicator (hereafter called the
Applicator) shall examine all drawings and provide for
the flashing, caulking and sealing of all vents, stacks
and pipes penetrating the roofing membrane. Also all
flashings at walls, parapets, verges, gutters etc., unless
otherwise instructed in the specifications.
The surface to which Butynol is to be fixed shall be
clean, smooth, dry and free from sawdust, grit or sharp
objects. Membrane laying shall not start until defects
have been corrected.
To avoid staining care should be taken to avoid water
runoff from copper downpipes or guttering on to light
coloured Butynol.
When CCA plywood is used in conjunction with a
light coloured membrane it is advisable to prime any
plywood that will not be covered the same day.
It is the responsibility of the Applicator to ensure that
the surface to be covered by the Butynol is in fit and
proper condition, suitable in all respects for the laying
of the material.
On completion the Applicator will provide the owner
with a Workmanship Warranty and obtain from Ardex a
Materials Warranty.

FORMING LAPS FOR GUTTERS
Laps are most important in gutter work and should be
formed using Ardex seam tape and seam primer.
All internal boxed gutters can be easily formed to
any shape or size using Butynol over any specified
substrate.
Black Butynol and roofs with minimum pitch of 5°
and sufcient fall to prevent periodic ponding may be
formed using the sheet bonding adhesive WA98. All
laps must be wiped with WA98 solvent prior to bonding.
BONDING THE LAPS
Roofs with a pitch of less than 5°, all coloured
membranes and all guttering and areas subjected to
periodic ponding require special lap bonding.
Refer Acceptable Solution E2/AS1 8.5.5.2a.
All coloured membranes, irrespective of pitch require
special lap bonding.
1. The top lap is positioned and the bottom sheet
marked to indicate the edge of the top sheet.
2. The top sheet is folded back.
3. The Ardex Seam Primer is then applied to the Butynol
in the area marked on the bottom sheet and 50mm
in from the edge on the top sheet. The Ardex Seam
Primer is applied to the mating surfaces using a
synthetic scrubbing pad. Scrubbing pads should be
replaced as they become dirty. Allow the primer to
become ‘touch dry’.
4. Position and unroll the 50mm Ardex Seam Tape
along the seam. The edge of the seam tape should
be aligned to the mark on the bottom membrane
sheet. The see-through backing lm makes this very
simple.
5. Roll the length of the seam with backing lm still in
place.
6. Remove the backing lm from the Ardex Seam Tape
by pulling at a 45° angle away from the seam. Keep
the backing lm low to the roof surface as it is
removed.
7. Fold into place the primed edge of the top sheet.

LOOSE LAID APPLICATION OF BUTYNOL ROOFING
Materials used shall be as previously specified. When
the surface is suitably prepared a large fully vulcanised
Butynol sheet or sheets can be unrolled and spread
over the prepared area and allowed to remain in this
position for approximately one hour to relieve stresses
induced by manufacture and storage. If necessary
for ease of handling, these sheets can be supplied in
varying sizes and vulcanised on site using an Ardex
vulcanising machine or using seam tape with seam
primer.
The Butynol sheet shall be set out in the exact position
in which it will be finally required and whilst it is held
firmly in place it shall be folded back at least one metre
from the roof's surrounding parapet or wall to allow
the application of adhesive to that area of the exposed
substrate.
WA98 adhesive may be applied to the substrate and the
corresponding area of Butynol sheeting which may then,
when the adhesive is touch dry, be worked back into its
required position avoiding wrinkles and the inclusion of
air bubbles.
Upon completion of the detail work, parapets, drains
and rainheads etc a layer of rounded gravel 30-40mm
should be applied up to 50mm deep, over a layer of
Geo Textile Fabric for protection of the Butynol sheet.
Care must be taken at outlets to ensure the ballast
cannot enter or cause a blockage that prevents
rainwater from leaving the roof area. Maintenance
paths should be created to air-conditioning or roof plant
with concrete tiles.
Effects on the membrane in areas of high wind can be
eliminated by stabilising the ballast with cement. Dry
cement should be broadcast over the 30-40mm gravel
with a broad mouth shovel and left to hydrate or lightly
sprayed with water to set off.
If possible a water test should be carried out prior to
the application of ballast.
Note: Minimum pitch 1.5° to comply.
Refer NZBC Clause E@/AS1 External Moisture 8.5.1 (a).

ARDEX Butynol Shingles
LAYING ARDEX BUTYNOL DIAMOND SHINGLES
Setting Out
1. Mark the substrate horizontally with a chalk line
350mm up from bottom.
2. Mark a vertical line, top to bottom, and centre of
the roof.
3. Mark off 300mm vertical spacings from the centre
vertical line (both sides).
Laying
1. Cut a starter flashing wide enough to cover the
first 350mm at the bottom edge of the roof, up to
the horizontal chalk line, allowing extra in width for
gutter or fascia flashing.
2. Apply adhesive, and lay when ready.
3. Starting from the centre vertical chalk line, loose
lay the first shingles, making sure that the top and
bottom are in line with the vertical marking. Now
loose lay the entire bottom row, making sure each
shingle is butted up to each other.
4. With chalk, mark the starter flashing where the
adhesive should be applied using the loose laid
shingles to mark around. This is to eliminate over
brushing of adhesive.
5. Remove loose laid shingles and apply adhesive to
substrate and shingles which are to be laid (up to 5
shingles are manageable at one time).
6. Lay when ready, starting with centre shingle and
making sure each shingle aligns with vertical
markings and is well butted together.
7. Lay entire bottom row first.
8. Following rows are laid identically, but are
staggered and overlap row below by 25mm.
9. Each shingle must be carefully rolled, paying
special attention to lapped edges.
10. The top row of shingles may be cut to suit the
specifications and a Butynol overflashing used to
finish the ridge.
Any excess adhesive should be cleaned off as you go
with WA98 solvent.
Roof area coverage of 50 shingles is approximately
8.82m
2
.
After doing 350mm bottom flashing #1, then start
laying full shingles #2, #3, #4 etc.
Always start from centre on first row.
LAYING ARDEX BUTYNOL STANDARD SHINGLES
Priming Substrate
In areas where rain could interrupt work, it is
recommended that a primer coat of WA98 adhesive be
applied to substrate to prevent penetration of moisture.
Underashings
Glue and fix Butynol 380mm underflashing down barges,
valleys, hips etc. and also along the bottom of the roof
allowing an overhang into the gutter.
Laying
1. Make a chalk line horizontally along the roof, one
shingle height up. This line marks the top of the first
row of shingles. Apply adhesive by brush or roller to
substrate and shingle - approximately five at a time
for one person - pulling off plastic backing before
doing so. After flashing off time locate the top of the
shingle on the chalk line and smooth down.
2. To locate the next row, mark a horizontal chalk line
up one shingle height minus the overlap onto the
lower shingle.
3. Each shingle must now be carefully rolled, paying
special attention to lapped edges.
4. The top row of shingles may be cut to suit the apex
and a Butynol overflashing used to finish at the ridge.
Any excess adhesive should be cleaned off as you go,
with WA98 solvent.
Roof area coverage of 50 shingles is approximately
3.57m

Episeal EPDM Roofing
E2/AS1 Acceptable Solution
ARDEX WPM 2000EP
Perimeter fixings normally required for solid EPDM
membranes are not required for Ardex Episeal due to the
Fibre Backing which allows the membrane to relax after
manufacture and prevents shrinkage normally encountered
after installation of EPDM sheeting
31
SPECIFICATION
Ardex Episeal is a high performance synthetic rubber
membrane based on the polymer Ethylene Propylene
Diene-Monomer (EPDM) combined with a Polyester Fibre
Mat backing.
Ardex Episeal has properties which resist ageing
from heat, sunlight and ozone. It has excellent gas
impermeability and toughness and remains flexible at
low temperatures.
Ardex Episeal is marketed by Ardex as a warranted
roofing product and fixed by approved Applicators.

Episeal EPDM Roong E2/AS1 Acceptable Solution
32
33
SUBSTRATE SPECIFICATION (Plywood)
To conform with Acceptable Solution E2/AS1 plywood
shall be:
A minimum of 17 mm complying with AS/NZS 2269, at
least CD Structural Grade plywood with the sanded C
face upwards, and H3.2 with Waterborne CCA treatment
and kiln dried after treatment.
Substrates must be dry when Episeal is applied. The
plywood and the timber substructure shall have a
maximum moisture content of 20% when Episeal is
adhered.
Plywood panels shall be laid with staggered joints
(brick bond), the edge of sheets shall be supported
with dwangs or framing, unless a structurally tested
tongue-in-groove edge provides equivalent support.
The maximum recommended span in E2/AS1 is
400mm in each direction. However specific design
may allow 17.5mm plywood or greater to be laid on
400mm purlins with nogs or dwangs at 600mm or even
1200mm centres. Plywood shall be laid with the face
grain at right angles to the supports. A 20mm triangular
fillet shall be used at the base of any 90° upstand.
External edges shall be chamfered with a minimum
radius of 5mm.
Plywood shall be fixed with 10g x 50mm stainless steel
countersunk head screws, eg Hylton Parker No 24639
or No 12923 for Steel Purlins, with 3mm gaps between
all sheets, at 150mm centres on edges, and 200mm in
the body of the sheets.
All joints in the plywood and junctions of plywood with
other materials shall have 25mm polyethylene release
tape applied before application of Episeal.
Closed-in construction spaces under Episeal roofs and
decks shall have adequate ventilation to prevent the
accumulation of moisture under Episeal. There should
be a minimum gap of 20mm between the underside of
the substrate and any insulation.
For roof or deck areas over 40m
2
, roof vents will be
required.
NOTE: The use of LOSP (Light Organic Solvent
Preservative) treated plywood must NOT be used
under Episeal in any circumstances or conditions.
SUBSTRATE SPECIFICATION (Concrete)
New concrete
Must be cured for a minimum of 28 days and all curing
compounds removed prior to application.
A reduction in cure time can be achieved by utilising
the Ardex HydrEpoxy System (consult Ardex Technical
Department for details).
Old concrete
Must be clean from any contaminents prior to
application.
For further substrate types please consult Ardex
Technical Department.
Ardex Episeal gives the Designer or Specifier of
Membrane Systems the opportunity to provide clients
with a time proven waterproofing system that acts
as permanent venting of the substrate, and most
importantly can be applied to new substrates or over
existing membrane systems, avoiding excessive cost
and disruption to the client normally associated with
such an exercise.
Ardex Episeal assists in ventilating substrates
permanently by allowing moisture drawn from the
substrate to dissipate through the fibre backing of the
membrane to perimeter flashings, or to strategically
positioned Vapour Release Vents.
Ardex Episeal with its fibre backing has high resistance
to mechanical damage, puncture and tear. The fibre
backing allows the membrane to take up minor
undulations in the substrate, particularly useful when
applied over existing membrane systems.
Ardex Episeal may be applied over various substrates
such as built-up roof systems, malthoid, liquid
membranes and earth formed dams. Substrate bonding
is achieved with a variety of specially developed
adhesives.
Ardex Episeal can be applied to XPS using suitable
adhesives. Contact Ardex for details.
Ardex Episeal can be applied onto Polyurethane Foams,
providing an instantly suitable substrate with insulation
properties. Consult Ardex for details.

ARCHITECTURAL SPECIFICATIONS
1. Introduction
Ardex Episeal is a roofing system designed primarily
for the retrofit of existing bitumen, malthoid, concrete
or tongue and groove sarking. The membrane
incorporates a polyester fleece which is laminated to
the underside of the sheet membrane. This fleece
provides an excellent means of ventilation for the
membrane as well as increasing the puncture resistance
of the membrane.
2. Scope
This rubber roofing specification consists of the
provision and fixing of all the rubber roofing and
flashings referred elsewhere in the manual.
3. Contractors
The rubber roofing shall be fixed by roofing contractors
specially skilled in this work and approved by the
manufacturer or distributors of the material selected.
4. Workmanship
The roofing contractors shall supply the main contractor
when requested, written warranties covering the
waterproofing properties of the rubber membrane and
joining tapes etc., along with his own workmanship
warranty covering the fixing of the membrane. It will
include making good any defects which are covered by
the said warranties.
Should the architect raise any queries on any aspect
of this work, the roofing contractor shall attend a site
inspection and if required, the manufacturer or his
appointed agent may also be called to attend.
5. Materials
Rubber membrane - For the purpose of this
specification the approved single ply membrane system
shall be:
Ardex Episeal fibre-backed
colour - Black
gauge - 1.2mm, 1.5mm
Lap tapes and other accessories as specified by the
manufacturer for use with the selected membrane.
Adhesives shall be as detailed in the accessories
section of the manual.
6. Acceptable Substrates
• Structural concrete
• Plywood
• Modified bitumen roofs
• Malthoid
• Tongue and grooved or butt joined sarking
• Polyurethane foams
• Nuralite
• Nuraply
Before applying Ardex Episeal the substrate should
be cleared of any sharp protrusions or penetrations
that may risk the integrity of the rubber membrane in
application.
7. Membrane Application
1. Check that substrate is in a suitable condition as
stated above. If in doubt contact your local Ardex
representative.
2. Tape any large cracks or voids with suitable width
self adhesive tape. Ensure the existing membrane
is fixed securely to the substrate. Any large areas
that have separated from the substrate should be
either removed or nailed back into place.
3. Prime the substrate if required with the selected
adhesive cut back 50% with its solvent.
4. Position the membrane and allow to relax where
it is to be laid, allowing for the side laps to be in
the correct position for adhesive application. See
diagram page 40.
5. Fold back half the sheet that is to be applied.
6. Apply Ardex Episeal adhesive to the substrate
surface and if a contact adhesive is used to the
Ardex Episeal membrane as well.
7. Fold over and adhere working progressively
towards the edge of the sheet. Wrinkles can be
smoothed out with a soft bristle broom, but do not
stretch the sheet.
8. Fold back other edge, adhering the other half of the
sheet in the same manner as the first half.
9. Bonding the laps
9.1
The top lap is positioned and the bottom sheet
marked to indicate the edge of the top sheet.
9.2 The top sheet is folded back.
9.3 The Ardex Seam Primer is then applied to
the Ardex Episeal in the area marked on the
bottom sheet and 50mm in from the edge
on the top sheet. The Ardex Seam Primer
is applied to the mating surfaces using a
synthetic scrubbing pad. Scrubbing pads
should be replaced as they become dirty.
Allow the primer to become ‘touch dry’.
9.4 Position and unroll the 50mm Ardex Seam
Tape along the seam. The edge of the seam
tape should be aligned to the mark on the
bottom membrane sheet. The see-through film
makes this very simple.
9.5 Roll the length of the seam with backing film
still in place.
9.6 Remove the backing film from the Ardex Seam
Tape by pulling at a 45° angle away from the
seam. Keep the release paper low to the roof
surface as it is removed.

9.8 Roll the completed seam.
10. Place the roll of overlay tape on roof a metre
ahead of the application start point. Position the
roll so that the release paper unrolls from the top
of the roll. The release paper will be on top. Peel
the release paper up and back from the overlay
tape. Unroll the overlay tape along the seam taking
care not to stretch the overlay tape during its
application. Take care to avoid wrinkles. Smooth
the tape down into contact with the membranes.
11. Roll the sheet membrane and the seams with a
heavy roller to ensure a good uniform bond is
achieved.
12. End laps must be primed with seam primer and
150mm overlay tape. See diagram page 40.
13. Detail work and roof penetrations can be flashed
with 150mm wide detail tape.
14. Seal all cross joints and T-joints in overlay tapes
with Butynol sealant.
15. Edge sealing must be carried out when laying
is halted due to rain in time to prevent moisture
getting under the fibre backing.

ARDEX Optima
DESCRIPTION
Ardex Optima is a two component cementitious
acrylic modified white adhesive. When mixed in the
recommended portions Ardex Optima produces a
resilient water resistant adhesive for bonding most
ceramic tiles to Butynol Synthetic Rubber and other
substrates (see below).
APPLICATION RANGE
Location
Internal, external and water immersion.
Performance Levels
Residential, commercial and industrial.
Surfaces
Walls, floors and decks.
Tiles
Natural stone, porcelain, mosaics, fully vitrified &
ceramic tiles.
Uses
Particularly suited for adhering ceramic and clay
tiles to Butynol decking and facings as per the Ardex
recommended direct-stick system described below.
Other suitable substrates
• Brick and blockwork
• Fibre cement sheets, plaster boards
• Tilt up and pre-cast concrete
• Cement render, concrete, aerated concrete
• Powder coated cladding, galvanised, stainless steel
(degreased), brass
• Existing tiles (thoroughly cleaned)
• Superflex and Shelter acrylic waterproofing
membranes
• Particleboard
• Roughened fibreglass
SUBSTRATE PREPARATION
Butynol
Butynol must be cleaned to remove any dust or
contaminants. This can usually be accomplished by
using sugar soap and water, but if more stubborn
soils remain, contact your local Ardex representative
for instruction. Allow surface to dry before applying
adhesive.
MIXING
Mixing ratio three parts of powder by weight to one part
of liquid (weight or volume).
Mix adhesive by mechanical means until a homogeneous
creamy paste is achieved, do not over mix. Allow mix to
stand for 2 minutes prior to use.
APPLICATION
Tile installation must conform to the requirements of the
Australian Standard 4992-2003.
Lay the tiles using Ardex Optima applied to the
membrane surface using a 12mm notched trowel to
achieve a dry bed thickness of not less than 2.5 - 3mm.
Place the tiles in position and work into the adhesive to
ensure a 100% coverage to the reverse side of the tiles.
Only spread the adhesive to an area of approximately
1m
2
at a time to ensure that the tiles can be placed
before the adhesive forms a surface skin which will
inhibit the bond strength.
Allow the Ardex Optima to cure for at least 24 hours
before proceeding with the next stage. Low absorbency
tile can extend the cure time.
GROUTING OF TILES
All joints should be grouted using Ardex Grouts with
Grout Booster (80:20) after the adhesive has fully
cured. After mixing the grout in accordance with the
instructions work it well into the joints ensuring there
are no voids under the grout. Apply the grout to a small
area of approximately 1m
2
at a time and clean excess
grout from that area prior to proceeding. Only mix small
quantities of grout at a time to enable workability within
the pot life of the product.
Finishing Ardex Grouts should be carried out in the
normal fashion by allowing the residual grout film to dry
and polish off to totally remove.
Abapoxy
When using Ardex Abapoxy, cleaning the excess grout
from the surface should be carried out using a wet cloth
wrapped around a firm rectangular item such as a block
of wood to remove the bulk of the excess. Surface
should be finally cleaned using a clean wet scourer to
remove all excess material from the joints and the tile
surfaces.
