TR is a trafficable, high build, water based acrylic waterproofing membrane
primarily designed for use in areas of infrequent to moderate foot traffic.
Azcoflex TR is UV resistant, tough and durable but still flexible.
When cured it gives a seamless waterproofing membrane with excellent water
ponding resistance, low dirt pick- up and good thermal shock
stability. Although the tough polymer system provides an excellent
trafficable waterproof membrane, it can also be used on walls. It is a complete
protective waterproof barrier for severe weather conditions, wind driven rain,
salt spray and UV exposure.
Azcoflex TR has very low VOCs and meets the 'Green Star' environmental
TR (TR is for trafficable) is designed to provide a pedestrian trafficable
waterproofing membrane for the use on:
decks, terraces, podiums and balconies.
Walls, parapets and facades.
TR can be used over a wide range of properly prepared and primed substrates
cement, cement render, block work, brick, masonry, FC and CFC sheeting, timber.
information contained in this product data sheet is typical but does not
constitute a full specification as conditions and specific requirements may
vary from project to project. The instructions should be considered as a
minimum requirement but the applicator or contractor must use their skill, knowledge
and experience to carry out additional works as may be necessary to meet the
requirements of the project. Specification for specific projects should be
sought from the Company in writing.
Azcoflex TR is designed to withstand normal, occasional to moderate broad
soled foot wear traffic. Azcoflex TR can be damaged by point loads, sharp
edges, scuffing and scraping and should be protected from this.
It is important that large cracks and joints be independently waterproofed as
described under Detailing Preparation.
TR is both a waterproofing membrane and a trafficable coating.
Very low VOCs and meets the 'Green Star' environmental criteria.
User and environmentally friendly.
Can be tinted.
Provides a tough, trafficable membrane.
UV Resistant, suitable for exposed areas.
Water ponding resistant.
Low dirt pick-up - can be cleaned.
Can be readily repaired or over-coated, if required.
Can be used with a reinforcing fabric.
is considered low risk if used properly as intended. Whilst Azcoflex TR is a
user friendly product it is recommended that all safety precautions are
followed as per product label and data sheet. In exposed areas, do not apply if
rain is imminent and protect membrane from rain and inclement weather until
and Surface Preparation
preparation is essential. Surfaces must be sound, stable, dry, clean and free
of dust, loose, flaking, friable material and substances that may diminish
Surfaces should be suitably primed with Primeseal applied at no less than 1 Lt
per 4m2 and allowed to dry. Primeseal must be used for roof and exposed
areas, timber and particle board surfaces, bitumen or where there is a risk of
entrapped moisture in the substrate which may cause the membrane to bubble.
Alternative primers such as Azcoseal or Maxiprime may be used in
non-exposed areas and where the moisture content of the surface is very low
applied at no less than 1 Lt per 4m2.
Excessively porous, friable and dusty surfaces may require an additional

Prime as required.
Apply an adequate flexible polyurethane sealant, in accordance the
manufacture's instruction and tool off to form a solid, coved 45 degree
fillet extending at least 10mm on to the adjacent surfaces. Apply the membrane
directly over the sealant and on the adjacent surfaces.
For Additional waterproofing protection the following additional steps should
Lay a strip of Leak-Seal Tape (stick-stick, butyl mastic waterproofing membrane
with a polyester backed reinforcing fabric) over the cured polyurethane sealant
(as described above) pressing it firmly on the surface. Apply the Azcoflex TR
membrane directly over the tape and on the adjacent surfaces.
gaps and Cracks
gaps and cracks should be suitably filled and sealed with an appropriate
elastomeric sealant, preferably a polyurethane sealant, and allowed to
Recommendation: The movement of small cracks should not be underestimated
and should be at least covered with a flexible polyurethane sealant or
additional coats of membrane.
or Live Cracks
Large cracks should be routed out to form a 'V' and then filled and sealed with
a polyurethane waterproof joint sealant as per the manufacturer's instructions.
The sealant should be finished slightly proud of the surface and allowed to
After priming, as required, lay a strip of Leak-Seal Tape over the join or
crack pressing it firmly on to the substrate. The membrane is then applied
directly to the Leak-Seal Tape and extending at least 75mm on to the adjacent
the Leak-Seal is not used then a suitable bond breaker tape (such as duct tape)
at least 48mm wide should be laid over the join or crack and apply a fully
reinforced membrane consisting of a base coat of Azcoflex TR membrane in to
which the reinforcing fabric is embedded, a saturating coat of the membrane
ensuring that the fabric is entirely saturated and covered and then allowed to
cure. At least one or two further coats are applied as per the membrane's
Product Data Sheet extending at least 75mm on to the adjacent surfaces.
- Particularly in CFC Sheeting and Timber Sheeting
Ideally the sides of the sheets should be fully coated with a flexible
polyurethane waterproof joint sealant prior to butting the sheets together.
If not, the joins should be suitably filled and sealed with an appropriate
elastomeric polyurethane waterproof sealant and finished flush with or
preferably slightly proud of the surface and allowed to cure.
After priming, as required, lay a strip of Leak-Seal Tape over the join,
pressing it firmly on to the substrate. The membrane is then applied as
described under 'Large or Live Cracks'.
the Leak-Seal is not used then follow the procedure as described under 'Large
or Live Cracks'.
Outlets, Penetrations and Angles
Waste Outlets: Floor wastes and puddle flanges should be rebated in to the
floor to allow water to readily drain and its perimeter edges and gaps sealed
with a polyurethane sealant.
Plastic or metal angles: Where required by the Building Code such as internal
hobs and exterior door barriers and also plastic corner angels under wall
boards, should be securely embedded in to a continuous, gap free bed of a
polyurethane sealant / mastic.
can be with brush, spray or roller. Where exposed to the elements, do not
apply membrane if rain is imminent and protect the membrane from water and
damage until it has fully cured.
1st & Saturating Coat (done in one step).
Apply a first coat of Azcoflex TR using brush, roller or spray over the
prepared and primed surface at the rate of 0.5 Lt sq.m. Embed fibreglass
matting or Durascrim reinforcing fabric into the wet membrane. The reinforcing
must be well worked into the wet membrane to eliminate trapped air and
wrinkles. Immediately apply a saturating coat at the rate of 0.5 litres per
sq.m. ensuring the the fabric is entirely embedded and covered. Allow to cure.
Inspect the cured surface and cut out and replace any trapped air bubbles
before proceeding. The surface should be smooth with a regular profile from the
embedded reinforcing and free of bubbles, wrinkles or surface defects. Allow to
Apply a second coat of Azcoflex TR by brush, roller or spray at the rate
of 1.0 Lt per sq.m. Allow to cure.
There are occasions when the use of a third application might be considered
necessary. Typically this should be considered in coastal/marine environments
or where excessive pedestrian traffic is anticipated. Application will be at
the rate of 0.5 litres per sq.m.
The minimum dry film thickness of the membrane should be at least 1.5mm.
Apply two coats of Azcoflex TR at the rate of 2m2 to 3 m2 per Lt per coat. The
minimum dry film thickness should be at least 500 microns. The crack bridging
properties of the coating is dependent upon the cured thickness (the thicker
the membrane the more it will flex) and additional coats may be required
over doubtful areas.
stated average coverage rate may vary depending upon type, condition, porosity,
texture of the surface and application technique.
The total combined use of Azcoflex TR should be a minimum of 2 Lt per m2.
Unreinforced: The total combined use of Azcoflex TR should be at least 1.5 Lts
Walls: The total combined use of Azcoflex TR should be at least 1.0 Lt per m2.
TR can be tinted to a wide variety of Light colours.
