IAs self smoothing topping of 1.5 3 mm thickness for : ILeveling or patching concrete surfaces, both unfinished and after grinding or planning. I EpoCem floors on non-ventilated damp substrates with low estheticconsiderations. I Levelling layer beneath epoxy floor coatings. I Self-levelling toppings as a substrate for synthetic floor coating, carpets, or wooden parquet. I Repair and maintenance of monolithic and vacuum concrete floors. Extended with quartz sand, as a patching and repair mortar for : ISurfaces to be coated with epoxy resins. Designed for use on cementitious, mineral-based substrates. AdvantagesISimple application system ICan be overcoated with epoxy resin compounds after 24 hours (20C, 75 % r.h.) IEconomical in use and easy to install IGood leveling properties IWaterproof IFrost and de-icing salt resistant IPermeable to water vapour IThermal expansion properties similar to concrete IExcellent adhesion to damp and green concrete IExcellent early and final mechanical strengths IExcellent resistance to water and oil IWill not corrode reinforcement IPre-dosed sets Product Data Colour Light-grey (mix) Storage Storage Conditions/ Shelf-Life Part A, part B: 12 months Part C:9 months From date of production if stored in original, unopened and undamaged sealed packaging, in dry conditions at temperatures between +18C and +30C.

A : B : C = 1.14 : 2.86 : 18-19 (by weight) , according to desired application and substrate temperature Material consumptionPrimer (depending on application) ISika Repair/Sikafloor EpoCem Module (Comp.A+B), approx. 200-300 g/m depending on substrate condition. This primer must be used if Sikafloor-81 EpoCem ID is being broadcast with sand in excess, or overcoated with a self-levelling floor coating on normal absorbent substrates. On porous or excessively absorbent substrates use Sikafloor-155 WN instead. ISikafloor-155 WN (Comp. A+B), thinned with 10% water, approx.300-500 g/m (depending on substrate conditions)). Sikafloor -155 WN is being used when repairing mono or vacuum-concrete, also if Sikafloor-81 EpoCem ID is applied without sand-finish or when Sikafloor EpoCem is overcoated with thesame material. Self-levelling floor ISikafloor-81 EpoCem ID (Comp. A+B+C) approx. 4.5 kg/m for 2 mm layer thickness. Substrates preparation The substrate must be structurally sound and free from all traces of loose material, laitance, oil and grease. Substrates must be dry or saturated surface-dry (no standing water). Adhesive tensile strength at least 1.5 N/mm. Application Conditions Shake comp. A (while liquid) briefly, then pour into comp. B and shake vigorously for at least 30 seconds.Stir material before taking it from a drum. Pour the binder mixture (A+B) into a suitable pail (approx. 30 litre capacity) and add Comp. C, whilst mixing with an electric stirrer. Mix thoroughly for at least 3 minutes. To repair surface irregularities and holes deeper than 3 mm, the standardSikafloor-81 EpoCem ID mix may be extended with dry quartz sand. Mix-guide ISikafloor-81 EpoCem ID(Comp.A+B+C)23 kg I(mixed well for 3 minutes) add : ISikadur-508 (quartz sand 0.7-1.2 mm)5 10 kg ISikadur-510 (quartz sand 2-3 mm) 10 12 kg Mixing instructions To achieve good bond of the mortar to the substrate, SikaTop-Armatec 110 EpoCem or other suitable primer must be used as a primer. (please consult Sika Technical Service). Apply mortar wet on wet to the primer. Sikafloor 81 EpoCem ID3/33 Application methodApply primer by roller. Avoid the formation of puddles. (For choice of primer, please refer to Material Consumption). At 20 C and 75 % r.h. Sikafloor-81 EpoCemID mix may be applied to the primed substrate after the following minimum waiting time : IWith Sika Repair/Sikafloor EpoCem Module : 1 hr. IWith Sikafloor-155 WN :12 hrs. Sikafloor 81 EpoCem ID must be evenly spread with suitable rubber or metal trowel and immediately rolled with spiked roller to remove entrapped air and to obtain an even layer thickness. Workability may be adjusted by slightlyvarying the Comp. C content (see mixing ratio) Cleaning of tools Clean all tools with water immediately after use. Once cured, Sikafloor-81 EpoCem ID must be removed mechanically. Layer thickness min 1.5 mmmax. 3.0 mm (holes of 3-5 cm diameter : Layer thickness max. 10 mm) IMin. substrate temperature +8C IMax. substrate temperature :+30C IMax. ambient temperature: ~30 CIMax. relative air-humidity:~80 %.IOn no account should any water be added to the mix. Notes on application IIf Sikafloor-81 EpoCem ID is used as a temporary moisture barrier,the whole area must be coated to a min. layer thickness of 2 mm. *If relative air humidity over 80% make slow setting and moisture accept morethan 1 day. Reactivity (75% r.h.) 30 C Pot life (23 kg)~20 min. Waiting times ICan be walked on after: 15 hrs. ILight mechanical loading after:2days IFully cured after:7days ICan be overcoated with epoxybased materials as soon as surface moisture content of EpoCem is less than 4%, however not earlier than:1day Safety precaution Product may cause skin irritation.
