Concrete Treatments - Repair - Moisture Barriers
Sikafloor-81 EpoCem is a 3-component epoxy modified cementitious self smoothening floor topping and temporary moisture barrier. It is used as a temporary moisture barrier (2 mm thick) for epoxy and polyurethane floors, as a self-levelling topping of 1.5-3mm thickness for:
• Levelling or patching concrete surfaces, both unfinished and after grinding or scabbling.
• Coloured EpoCem floors on non ventilated damp substrates with low aesthetic considerations
• Floor toppings beneath epoxy protective coatings.
• Self levelling toppings that are to be covered with polymer floor coatings, carpets or wooden parquet.
• Repair and maintenance of vacuum concrete floors.
Extended with quartz sand, it can be used as a patching and repair mortar for surfaces that are to be coated with epoxy resins. Sikafloor-81 EpoCem is designed for use on cementitious, mineral-based substrates.
Sikagard-720 EpoCem is a 3-component epoxy-modified cementitious sealing and levelling mortar, suitable for application to most mineral based substrates. It’s specific balanced formulation ensures that the properties of the hydrated cement are both complemented and enhanced by the integral epoxy mortar.
Sikagard-720 EpoCem may be used on both vertical and horizontal surfaces of concrete, mortar or stone.
The thixotropic mortar can be applied as a thin layer coating, 0.5 – 2 mm thick or as a scraping/levelling mortar to fill in blow holes, shallow honeycombing and other surface irregularities. It’s ability to provide a temporary moisture barrier provides an ideal substrate for subsequent epoxy coatings
Sikagard-680S is a 1-component methacrylic resin based protective and decorative coating. It protects concrete and most mineral-based substrates against aggressive atmospheres, moisture ingress and carbonation. Sikagard-680S allows two- way water vapour diffusion enabling the treated structure to breathe.
Sikagard-680S may be used to overcoat most mineral substrates including concrete, stone, fibrous cement, suitable brickwork and block-work. Sikagard-680S is ideally suited as a final protective coating in concrete repair and building facade refurbishment work to halt the process of carbonation, aggressive ion infiltration and other atmospheric contamination.
Sikatop 107 Seal is a two component, pre-dosed, ready to use waterproofing slurry based on polymer modified cementitious material.
It can be used on concrete, brickwork and mortar (as a rigid waterproofing membrane), on balconies, terraces and small flat roofs (as a thin layer render in concrete repair) and on wharves, piers and docks (as a waterproof protective coating).
Bostik Moisture Seal is a two part, high performance, water based epoxy moisture and vapour barrier formulated to prevent water seepage and permeation in building and construction substrates.
It is recommended for in-situ concrete, brick, block and stone work, fibre cement and AAC systems and
pre cast and tilt up panels.
Bostik Moisture Seal features are:
• Easy water clean up
• Withstands high levels of hydrostatic head of water pressure (up to 25 metres or 250 kPa)
• Excellent adhesion to recommended substrates
• Convenient equal part mixing ratio by volume or weight
• Approved for use with potable (drinking) water, conforms to AS4020 (1992)
• Tested to ASTM E96 for water vapour transmission
• Environmentally friendly
• Non flammable, negligible odour and toxicity
Dribond Epecrete is a multipurpose water based three pack epoxy resin. EPECRETE has excellent adhesion to most correctly prepared building surfaces such as brick, block, concrete and masonry.
It is used as a damp-proofing membrane on concrete floors prior to floor coverings where moisture exceeds Australian Standards and to stop dampness in cellars, basements, etc., and as a repair mortar for patching holes and anchoring steel bolts in concrete. Dribond Epecrete has high comprehensive strength and good chemical and abrasion resistance.
