Waterproof exposed balcony liquid membrane :  


Azcothane Reo is a water-based, flexible, high performance, polyurethane fortified acrylic emulsion waterproofing membrane formulated for use is demanding exposed, under tile, underground and immersed waterproofing applications. Azcothane's Reo formulation complies with AS4858:2004 and is generally applied in accordance with AS3740:2004.

It is liquid applied and cures to form a durable, flexible, strong, UV resistant, odourless, seamless, and impervious waterproofing membrane. It does not re-emulsify after it has fully cured making it ideal for long-term waterproofing. It will not stain grout or tiles.

 

Uses

 

Azcothane Reo has been specifically designed for exposed, under-tile, underground and immersed waterproofing requirements included the long-term waterproofing of:

 

Exposed concrete and metal roofs

Wet areas within buildings (shower recesses, bathrooms & laundries)

Ponds & water features

Concrete and timber decks

Terraces and balconies (under tiles)

Concrete slabs

Retaining walls

Planter boxes

Water retaining structures

Tiles or topped areas

Suitable Surfaces

 

Azcothane Reo is suitable for properly primed: Concrete, cement, cement render, block work, brick, masonry, FC sheeting and CFC sheeting, plaster board and timber, plywood and particle board (if primed with Primeseal) and metal (if primed with a metal primer). 

Note: We do not regard particle board as a suitable substrate for wet areas and if posible should be replaced or covered with CFC sheeting - particularly in shower recesses. If covered we recommend that the particle board be coated with 2 coats of Primeseal and joins and corners sealed with a polyurethane sealant prior to laying the CFC sheeting.

Azcothane Reo may be applied to slightly damp surfaces but the product will not fully cure if the surface remains damp. This process takes longer than if the surface was allowed to dry before application. The surface must dry before the membrane can dry. Freedom from surface water, continual dampness is essential. 

Priming of all surfaces is highly recommended.

Additional Uses

Azcothane Reo has been formulated as a completely versatile waterproofing membrane, available in a range of colours, making it is suitable for:

Exposed to direct sunlight on roofs (flat, sloping or metal deck).

Under tile applications - wet areas, balconies, terraces etc.

Underground applications - retaining walls, planter boxes and garden areas.

Immersed applications - ponds and water features.

 

Specification

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.

Precautions in Use

The product is considered safe to use if used correctly, as intended and proper industrial hygiene and practices are used. Always observe safety precautions.

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.

 

Priming 
Surfaces should ideally be primed with Primeseal applied at no less than 1 litre per 4m2 and allowed to dry. Primeseal must be used for roofs 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.
Priming is adequate if the surface has a solid off-white appearance. Particle board and bitumen surfaces should primed with 2 coats of Primeseal.
Alternative primers such as WB Primer, may be used in non-exposed areas and where the moisture content of the surface is very low applied and applied at no less than 1 litre per 4m2. Allow WB Primer to fully dry before top coating.
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

Corners
Prime as required.
Apply an adequate flexible polyurethane sealant, in accordance the manufacture's instruction and tool off to form a solid, coved or 45 degree fillet extending at least 10mm on to the adjacent surfaces. Allow sealant to cure. Apply the Wrimco membrane directly over the cured sealant and on the adjacent surfaces.
For Additional waterproofing protection the following additional steps should be taken
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 Wrimco membrane directly over the tape and on the adjacent surfaces.

Joins, Gaps and Cracks
General
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 Leak-Seal Tape over the join or crack pressing it firmly on to the substrate. The Wrimco membrane is then applied directly to the Leak-Seal Tape and extending at least 75mm on to the adjacent surfaces.

If 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 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.

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 Leak-Seal Tape over the join, pressing it firmly on to the substrate. The Wrimco membrane is then as described under

 

'Large or Live Cracks'.
If the 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. Gaps and perimeters should be 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, they should be securely embedded in to a continuous, gap free bed of a polyurethane sealant / mastic.

Application

Stir well. Apply by brush, roller, soft broom or squeegee.
Apply in a minimum of two coats. To perform correctly the dry film thickness of the membrane must be at least 1.0mm to 1.2 mm.
Azcothane Reo is suitable for use with a reinforcing fabric and Leak Seal Tape.

 

Reinforced System
In areas such as corners and over joins and cracks the membrane can be used in conjunction with a reinforcing fabric (Durascrim or fibreglass matting). This application consists of applying a base coat in to which the reinforcing fabric is laid followed by the application of a saturating coat ensuring that the product is worked well in to the fabric and that no wrinkles or bubbles are present and that fabric is entirely saturated and covered with product. Allow to cure. Apply one or two further coats of products so that the dry film thickness is at least 2.00mm.Usually not required when using the Reo grade.

Coverage

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

 

Azcothane 
Unreinforced: Minimum 1.5 litres to 1.8 litres per m2 ., i.e 0.75 litres to 0.9 litres per m2 per coat. A 15 litre pail will cover 10 m2 for 2 coats at 1.0mm dry film thickness.
Reinforced: Minimum: 2.0 litres per m2.
The dry film thickness fo the unreinforced membrane must be at least 1.00mm and preferably 1.2mm.

Primers
Minimum 1 litre per 4m2.
