Uses
Durabit REO has been formulated for most waterproofing applications requiring long term waterproofing, making it ideal for:
Shower Recesses & wet areas
Decks
Terraces, balconies, podiums and roofs (tiled or topped)
Retaining walls
Planter boxes.
Suitable Surfaces
Suitable for properly primed:
Concrete
Cement
Cement Render
Timber (use only properly approved timber for wet areas). We do not recommended particle board for this purpose.
Brick and block work
FC and compressed sheeting
Plaster board
Metal
Durabit REO may be applied to slightly damp surfaces but the product will not fully cure if the surface remains damp. Freedom from surface water and continual dampness is essential.
Specification
The information contained in this data sheet is general in nature and refers only to the usual use of the product and it should not be construed to be a complete specification. Site conditions vary which may require the use of the products and related products to vary. For specific projects a written specification should be sought from the Company.
Limitations
Durabit REO is not designed for long term direct exposure to UV and should be tiled, topped or painted.
Durabit REO is not designed as a trafficable membrane although infrequent maintenance foot-traffic would be acceptable.
Benefits and Advantages
Durabit REO is a versatile membrane suitable for many demanding waterproofing applications.
As it is internally reinforced, no additional reinforcing fabric is required. This saves labour and time.
Latex based.
Formulated for wet area and under tile applications.
Does not re-emulsify after proper curing.
Tough, durable and flexible.
Dries fast.
Compatible with most tile adhesives.
Easy to apply.
Virtually odourless.
Will not stain grout or tiles.
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 Preparation
Good preparation is essential. Surfaces must be sound, stable, dry, clean and free of loose, flaking, friable material, dust and substances that may diminish adhesion.
Priming
Concrete, cement, masonry, cement render, plaster board, brick, block-work, FC & compressed sheeting should ideally be primed with Duram Primseal applied at 3 to 4 sq.m. per litre. However, Duram WB Primer can also be used.
Timber Surfaces must be primed with Duram Primeseal applied at 3 to 4 sq.m. per litre.
Metal must be treated for rust with a rust converter (in accordance with good painting practice) and primed with a metal primer.
Duram Primeseal and WB Primer may be applied to slightly damp surfaces but the surface must become dry in order for the products to dry. Damp surfaces will increase the drying time.
Solar Induced Vapour Transmission Areas
In areas where the sun may heat up porous areas that may contain moisture within the substrate and can lead to entrapped moisture under the membrane which can cause it to bubble, they should be primed with 1 or 2 good coats of Duram Primeseal. Ideally, membranes should be applied to cooling substrates.
Allow primers to dry before applying Durabit REO.
A polyurethane sealant/mastic should be applied to all corners, around waste outlets (which should be rebated below the surface), joins, gaps, holes and cracks and allowed to dry.
Application
Stir well. Apply by brush, roller or soft broom.
Apply in a minimum of two coats. To perform correctly the dry film thickness of the membrane must be at least 1mm to 1.2 mm.
Durabit REO is suitable for use in 'High Movement Areas' as described below.
High Movement Areas
These would include wall/floor joins, cracks, expansion joints, bases of penetrations and waste outlets. These should be filled with an elastomeric, polyurethane mastic/joint sealant and in corners tooled off to a 45 degree angle and allowed to cure. Over large cracks and joints, 50mm wide bond breaking tape should be laid. The Durabit REO should then be applied as follows:
Apply at least 2 coats of Durabit REO at least 0.1mm thick (wet coat) per coat allowing each coat to dry before applying the next.
Coverage
The stated average coverage rate may vary depending upon type, condition, porosity, texture of the surface and application technique.
Minimum 1.6 litres per sq.m., i.e 0.80 litres per sq.m. per coat. A 20 litre pail will cover 12.5 sq.m. with 2 coats being applied.
High Movement Areas: Minimum of 2.0 litres per sq.m.
Colours
Durabit REO is available in grey and blue. Special colours available upon request but minimum orders will apply.
Available in 4 and 20 litres pails.
Drying and Curing
Drying and curing of the product is affected by type, dryness and porosity of the surface, temperature, humidity, ventilation, climate conditions and application technique. Therefore drying and curing can only be given as a guide.
Durabit REO is a fast drying water based product.
Expected curing at 25oC at 50% RH:
Touch dry 4 hours per coat
Set 12 hours
Full cure 36 to 72 hours.
Storage
Store in a cool, dry area. Product is not flammable. Do not allow to freeze.
Shelf life is about 12 months.
Clean Up
Wet spills can be cleaned with water, but spills should be avoided.
Tiling, Topping or Top Coating
Durabit REO is compatible with most tile adhesives and 3:1 sand: cement beds. Ideally the beds should be sealed/waterproofed to prevent the bed absorbing and holding water. Selection of the tile adhesive should be compatible with the flexibility of the substrate. Two pack adhesives systems are preferred. Tiling must be done in accordance with AS3958.1-1991 and adequate expansions joints installed.
Safety & Precautions
Durabit REO is user friendly and safe to use if used correctly as intended. Nevertheless, protect eyes and skin and observe the safety precautions on the can and data sheet.
