Gripset 38FC SBR Fast Cure Membrane

Description

GRIPSET 38FC is a next generation, water based, fast curing, fibre reinforced SBR latex membrane designed for waterproofing applications to internal and external areas that will be covered over with toppings, tile beds or overlay finishes

Gripset 38FC utilises the latest in fast cure technology, enabling rapid recoat and tile over times. Flexible, elastomeric and with low water vapour transmission properties, Gripset 38FC is a high performance waterproofing solution for domestic and commercial projects with time constraints that require fast turnaround times

Features & Benefits

• Water based, solvent free, non-toxic and non-flammable
• Fast curing, able to be tiled over after only 4 hours
• Fibre reinforced for enhanced tensile strength and workability
• Can be flood tested after only 24 hours
• Waterproof with ability to withstand continuously wet environments and ponding without re-emulsifying
• Flexible & elastomeric, accommodating normal substrate movement
• Compatible with tile finishes, concrete, render and masonry toppings
• Fast turnaround time, waterproofing and tiling applications can be completed within one day
• Durable and tough seamless finish
• Excellent vapour barrier & low water vapour transmission properties
• Can be applied by brush, roller, or spray unit on horizontal and vertical surfaces

Compliant to AS 4858 and AS4654.1 for internal and external wet areas

Application

• Gripset 38FC is suitable for commercial, industrial and residential Applications

Uses

• Internal wet areas, bathrooms, laundries and tiled areas
• External wet areas balconies, decks, podiums, terrace floors
• Roofs and rooftop terraces to be covered over with screeds and toppings
• Sandwiching between existing and new concrete substrates
• Liquid vapour barrier between toppings and slabs
• General tiled areas to prevent moisture ingress

Surface Preparation

• All surfaces are to be clean, sound, smooth, dry, and free from loose material, dirt, dust, oil, grease, wax residues, laitance, curing compounds, release agents, existing coatings, moss, algae, sharp protruding objects and general surface contaminants that may compromise the adhesion of the overlaid membrane system
• Structurally unsound layers and surface contaminants to be mechanically removed by grinding, abrasive blasting or equivalent methods.
• Masonry surfaces to be pointed flush, and all surface defects including voids, holes, pitted sections, heavy undulations and non-structural cracks to be filled and levelled. Refer to Gripset 11Y enhanced repair mortar or the RLA range of repair mortars and levelling compounds for options
• Building surfaces must be fit for purpose, constructed and installed to manufacturer’s recommendations and relevant building standards in force at time of application
• Concrete to be allowed to cure for at least 28 days, and cement render/sand cement screeds allowed to cure for at least 7 days

Application & Coverage

• Gripset 38FC is to be installed in line with current edition, relevant volume and sections of the NCC (National Construction Code of Australia) pertaining to internal, external and general waterproofing applications within the scope of use for the product
• Product is to be applied by brush or medium nap roller
• Apply a minimum of 2 coats at a total minimum coverage of 1.5 litres/m²
• Minimum dried film thickness is 1mm
• Apply subsequent coats at different directions to the previous coat.
• A wet film gauge should be used to regulate correct coverage of each coat

Note: Coverage is dependent upon surface condition and will vary accordingly as uneven and porous surfaces will require greater coverage to achieve the specified film thickness.

Drying times

Re-coat:                             1 hour

Tiling/Toppings:            4 hours

Full Cure/Flood test:  24 hours

Important: :

Drying times are based on ambient temperatures @ 23°C and 50% RH. Drying times may vary subject to ambient/surface temperatures, humidity and substrate porosity.

Drying/curing times will be extended in cooler conditions and periods of high relative humidity.

Precautions

• Not to be used as a trafficable surface
• Not to be used as a finished membrane exposed to UV
• Do not apply to areas when rain is imminent
• Do not apply when surface or ambient temperatures are below 5°C or above 30°C
• Not to be used in areas subject to rising damp or negative hydrostatic pressure
• All finish coatings over this membrane must be water based and solvent free
