    "Wet-on-Wet” Application

    "Wet-on-Wet” ApplicationSome liquid systems are installed by applying a base coat, which is then allowed to dry, often over night risking contamination of the surface, before adding the top coat. The system then relies upon the bond between two separate layers.

    Elastoflex waterproofing systems are applied in a “wet-on-wet” application. The top coat is applied while the reinforced base coat is still wet providing total integration of the two layers into a single, chemically bonded membrane. This application avoids the risk of failure from insufficient coverage, lack of inter-layer adhesion from contamination and even delamination.

    Since the Elastoflex coating is applied in one operation, it allows the installation to be completed more reliably and quickly than other methods.  

  • System Design

    Designed to provide the optimum combination of aesthetic and functional performance the Elastoflex anti-skid surfacing products form an integral part of a complete system where waterproofing and surfacing are required.

    Elastoflex anti-skid surfacing products can be applied onto Elastoflex waterproofing systems, or onto various new or existing substrates, to form a durable hard wearing surface for walkways, balconies, terrace areas and podium decks.

    Prior to application, thoroughly mix the primer resin using a mechanical paddle mixer. The required quantity of catalyst should be added during the mixing process. Continue to agitate until fully mixed in. In colder temperatures, longer mixing times will be required.

    Workability times do not begin until the catalyst is added to the resin. Once mixed do not replace the lid.

    Apply Elastoflex Balcony & Walkway Primer (Summer or Winter grades) using a brush or roller at the specified coverage rate. When dry, an adequately primed substrate will display a glass like sheen to the cured surface.

    Do not try to re-apply the primer or walk over it once it starts to gel. This will prevent the primer from fully curing.

    Application Rates

    Application rates for the Elastoflex Balcony & Walkway Primer is 0.25kg/m² (the finished surface should achieve a glass like sheen).

  • Filler

    The Elastoflex Balcony & Walkway Filler is intended to fill cracks, gaps and voids of size less than 10mm in width. The catalyzed resin is ideal for gaps and cracks that are dynamic.

    Elastoflex Balcony & Walkway Filler is a two-component cold applied gap filler based on advanced Polymethyl Methacrylate (PMMA) liquid technology.

    Application Method

    Following application of the required quantity of Elastoflex Balcony & Walkway Waterproof Coating, immediately apply pre-cut sections of Elastoflex Balcony & Walkway Reinforcing Fabric into the coating, and roll the surface, eliminating potential air bubbles and encouraging saturation of the fleece. The fleece helps regulate layer thickness, as correct application occurs when the fleece is fully saturated, indicated by the colour change.

    Overlap adjacent sheets of the fleece by a minimum 50 mm. Ensure the overlaps areas (above and below) are fully saturated to maintain continuity of the waterproofing system.

    Allow the reinforced base layer to cure before applying a further top coat. It may be necessary to angle grind exposed edges prior to application of the top coat.

    Once cured, apply a further layer of Elastoflex Balcony & Walkway Waterproof Coating as the top layer, and lightly roll to remove excess material.

    See Elastoflex Balcony & Walkway Waterproof Coating product information sheet for coverage rates and installation guidance.

    Surface Preparation

    Ensure the substrate is sound, clean, dry and free of frost, dust and debris, and any material which would hinder adhesion. For confirmation of specific deck type preparation, refer to the Elastoflex Balcony & Walkway Installation Guide

    Application Conditions

    The atmospheric application temperature range for the Elastoflex Balcony & Walkway Surfacing Resin is 0 to 30 °C. Winter and summer grades are manufactured to accommodate application throughout the year. The surface of the substrate should be clean and dry and must be 3 °C above the dew point. If the surface is below or at dew point temperature, moisture can form at the surface and affect coating adhesion and curing.

    Personal Protective Equipment (PPE) should be worn.

    Installation Considerations

    Consideration should be made to the use of PMMA based materials on site, in relation to using the product around doors, windows and ventilation/air-conditioning air intake units. Take all necessary safety precautions. Switch off air-conditioning and use fresh and exhaust air plant, etc. Mechanical ventilation may be required in enclosed areas.

    Application Method

    Prior to application, thoroughly mix the surfacing resin using a mechanical paddle mixer. If applying the resin to the horizontal, thoroughly mix in the Elastoflex Balcony & Walkway Granules, ensuring the aggregate is fully wetted out. For vertical application the aggregate is not required.

    When ready, add the correct amount of Elastoflex Balcony & Walkway Catalyst Powder (refer to installation guide for the appropriate amount of powder to add) to suit the operating temperature and grade of resin. Ensure the catalyst powder is fully mixed. Once the catalyst is added it initiates the ‘working life’ of the material. This time will depend upon the substrate, ambient, and material temperature and the amount of catalyst added. Mix only enough material that can be applied within the working life.

    Pour out the material and spread evenly over the surface with a 4 mm serrated squeegee blade or trowel. To remove rake marks and create an even texture this should be followed over with a medium pile sleeve roller.

    Once applied, the Elastoflex Balcony and Walkway Surfacing must be allowed to fully cure before trafficking. To prevent unnecessary contamination, it should be protected from other trades.

    Once cured, apply Elastoflex Balcony & Walkway Waterproof Coating as the top layer at a rate of 1.5 kg/m². Lightly roll to remove excess material. The total dry film thickness is 2mm..

    Application Rates

    Application rates for the Elastoflex Balcony & Walkway Surfacing are as follows:

    Vertical: Applied in two coats at a rate of 0.85 kg/m² per coat.

    Horizontal: A single coat at a rate of 1.7 kg/m²

  • Advantages of PMMA Liquid Applied Membranes

    Benefitting from fast application and curing times, the Elastoflex Balcony & Walkway System combines waterproofing reliability with superior membrane durability, to offer specifiers and users a solution to aged or new build constructions. Incorporating a stitch bonded polyester reinforcement, the waterproof coatings are applied in a two layer application providing a fully reinforced, chemically bonded membrane.

    Fast Curing

    A key feature of a PMMA membrane is its ability to cure extremely quickly upon addition of the correct amount of catalyst to the receiving resin. Curing times can range from between 20 to 60 minutes depending upon the product used and the nature of application.

    As a result interruptions to residents and pedestrians are kept to an absolute minimum as the waterproofed area can be accessible within the same day.

    Durability

    The combination of the reinforced waterproof coating and the aggregated surfacing layer has a proven track record and generates exceptional durability properties which make the Elastoflex Balcony & Walkway membrane ideal for heavily trafficked areas.

    All Year Round Application

    Liquid waterproofing products based on PolyMethyl Methacrylate chemistry require the addition of a catalyst on site to activate the curing process. The amount of catalyst required to activate the waterproof coatings is determined by substrate temperature and resin volume and is typically calculated on site prior to commencement. The resulting affect is that PMMA based coatings can be installed at temperatures as low as -10°C or as high as +30°C permitting all year round application.
