Product Data Sheet

Azcoflex TR

Trafficable Acrylic Waterproofing Membrane


Azcoflex 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 criteria.


Azcoflex TR (TR is for trafficable) is designed to provide a pedestrian trafficable waterproofing membrane for the use on:
• Roofs, decks, terraces, podiums and balconies.
• Walls, parapets and facades. 

Suitable Surfaces

Azcoflex TR can be used over a wide range of properly prepared and primed substrates including:
• Concrete, cement, cement render, block work, brick, masonry, FC and CFC sheeting, timber.


The 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.


• The 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.

Precautions in Use

Product 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 fully cured.

Priming and Surface Preparation

Good preparation is essential. Surfaces must be sound, stable, dry, clean and free of dust, loose, flaking, friable material and substances that may diminish adhesion.


Surfaces should be suitably primed with Duram Primeseal applied at no less than 1 Lt per 4m² and allowed to dry.  Duram 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 priming coat.

Please refer to the product data sheets of the stated primers.

Detailing Preparation

Prime as required.
Apply an adequate flexible polyurethane sealant, in accordance the manufacture's instruction and tool off to form a solid, coved  45º fillet extending at least 10mm on to the adjacent surfaces. Apply the Duram membrane directly over the sealant and on the adjacent surfaces.
For Additional waterproofing protection the following additional steps should be taken
Lay a strip of Duram 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 Duram Azcoflex TR membrane directly over the tape and on the adjacent surfaces.

Joins, gaps and Cracks
Joins, gaps and cracks should be suitably filled and sealed with an appropriate elastomeric sealant, preferably a polyurethane sealant, and allowed to cure.
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.
Large 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 cure.
After priming, as required, lay a strip of Duram Leak-Seal Tape over the join or crack pressing it firmly on to the substrate. The Duram membrane is then applied directly to the Duram Leak-Seal Tape and extending at least 75mm on to the adjacent surfaces.

If the Duram 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 Duram membrane consisting of a base coat of Azcoflex TR membrane in to which the reinforcing fabric is embedded, a saturating coat of the Duram 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 Duram membrane's Product Data Sheet extending at least 75mm on to the adjacent surfaces.

Joins - 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 Duram Leak-Seal Tape over the join, pressing it firmly on to the substrate. The Duram membrane is then applied as described under 'Large or Live Cracks'.

If the Duram Leak-Seal is not used then follow the procedure as described under 'Large or Live Cracks'.

Waste 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.


Application 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.

Floor System:

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 Lts 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 dry.
2nd Coat.
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.
3rd Coat.
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 Ltsq.m.

The minimum dry film thickness of the membrane should be at least 1.5mm.

Wall System:
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.


The stated average coverage rate may vary depending upon type, condition, porosity, texture of the surface and application technique.


Reinforced: 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 per m²
Walls: The total combined use of Azcoflex TR should be at least 1.0 Lt per m².


Azcoflex TR can be tinted to a wide variety of  Light colours.
