It reacts with the calcium hydroxide in the concrete to produce an improved resistant and dust free finish. Horizontal old or new concrete surfaces, where a hard surface with light to moderate abrasion resistance is required e.g. warehouses, industrial plants, stores, shopping malls, parking structures, service stations, hangers etc. On concrete slabs where no specific curing efficiency or standards are required. Suitable for interior or exterior applications. As a densifier in the process of grinding and polished concrete finishes. Ready to use Easy to apply Improved chemical and abrasion resistance compared to untreated concrete Reduced dusting of concrete floors Reduced loss of water of new concrete while setting Improves cleanability Non-yellowing Good penetration Solvent free Colourless and odourless Environmentally friendly Stored in original sealed containers in dry, frost free conditions within the temperature range of +5 C to +32 C, this product will keep for a minimum of two (2) years. If frozen the product must be discarded. All substrates must be sound, dry and free from oil, grease, curing compounds impregnations, wax, coatings and loose material. For best results concrete floors should be treated 7-14 days after placement. Concrete less than 3 days old may contain excess moisture that will inhibit penetration of Sikafloor-CureHard-24 into the concrete. Polished surface hardener Sikafloor-CureHard-24 is ready to use straight from the counter. Sikafloor-CureHard-24 is applied in one undiluted uniform coat at an application rate between 5 to 7m²/litre (depending on the porosity of the substrate). For ground and hightly polished method. Add Curehard 24 to the girinding process to produce a hightly dense and lustre finish. To ensure maximum penetration, scrub material into the surface with a stiff-bristle broom or an industrial floor-scrubbing machine for a minimum of 30 minutes, and until product begins to gel or becomes slippery. Wet material lightly with water spray and rework it into the surface for another 10 to 20 minutes. After this process, rinse the floor and remove any excess material with a squeegee and wet vacuum. Do not allow the material to pond, as this will cause white staining when dry. On porous rough-textured or broom finished surfaces a second application may be required. The second application can be installed 2-4 hours following the first one and is recommended to ensure maximum densification and protection. Floors are available for use and vehicle traffic 4-6 hours after the removal of excess material. Sikafloor -CureHard-24 Page 1 of 3

Sikafloor -263 SL/264 Page 1 of 6

Surface Preparation Priming Mixing Cleaning Application Surfaces must be clean, dry and free from all traces of loose material, old coatings, curing compounds, release agents, laitance, oil and greases etc. Substrate compressive strength should be at least 25MPa, cohesive bond strength at least 1.5MPa and with moisture content below 4%. For Substrate Moisture content more than 4%, please refer to various priming options below. Structurally unsound layers and surface contaminants must be mechanically removed by abrasive blasting, blast-tracking or grinding. Substrates heavily impregnated with oil must be cleaned by torching or suitable solvent cleaning methods. To check that all traces of oil have been completely removed, sprinkle a few drops of water over the surface. If all water is quickly absorbed, the surface is sufficiently oil and grease free. If water forms into globules that remain on the surface, further thorough treatment of the substrate is necessary. Sikafloor -263 SL when used as a self-levelling floor topping will not reprofile irregular substrates. For reprofiling defects on horizontal surfaces a suitable patching mortar is required. The patching mortar can be of epoxy or cementitious base depending on the scope, particular conditions and requirements of the work. Contact the Sika Technical Department for further information. If Substrate moisture content is < 4%: Apply Sikafloor -160 in accordance with the Product Data Sheet. For the best results and to minimise pin-holing in the primer and the top coat, apply the Sikafloor -160 to substrates that are either decreasing in temperature or maintaining a constant temperature. If Substrate moisture content is > 4% and < 6% using Sika Tramex Meter (at the time of application): Apply Sikafloor 161 (Which is Sikafloor 264 Neat Part A+B). Please note that the moisture content must be < 4% pbw using the CM measurement or Oven Dry method. Substrates prone to rising moisture vapour (eg. slab on ground with no waterproof membrane underlay) or with a moisture content in excess of 6% should be treated with Sikagard -720 EpoCem or Sikafloor -81 EpoCem. These products provide a temporary moisture barrier so that the subsequent epoxy coating can fully cure and bond to the substrate without interference from rising moisture. Substrates treated with EpoCem products in accordance with the Technical Data sheets require no further priming once it s water content is less than 4%, prior to the application of Sikafloor -263 SL/264. Prior to mixing, stir component A (resin) thoroughly. Add the pigment pack and all of component B (hardener) and mix components thoroughly with a low speed electric stirrer (300-400rpm) for a minimum of 3 minutes until a uniform mix has been achieved. For self-levelling floor toppings add the required quantity of Sikafloor -263 filler gradually while continuing to mix, avoiding air entrapment in the manner of mixing. Mix until a homogenous consistency is achieved. All equipment should be cleaned immediately after use with Sika Colma Cleaner. Hardened material will have to be mechanically removed. Wash soiled hands and skin thoroughly in hot soapy water. Prior to application, confirm substrate moisture content is below 4%, where the substrate moisture content is 4% - 6% use Sikafloor 161 in accordance with guidelines above. In case of moisture content more than 6% Sikafloor - EpoCem should be applied as a temporary moisture barrier. High build roll on coating Sikafloor -264: Apply mixed Sikafloor -264 onto unprimed substrate by brush or roller. For heavy duty service or for surfaces with abnormal absorbency, prime with Sikafloor -160. Self Levelling Floor Topping Sikafloor -263 SL: Pour mixed Sikafloor -263 SL onto primed substrate and spread evenly to the required thickness with a notched trowel. Roll immediately in two directions with a spiked roller. Anti-slip Self Levelling Floor Topping Sikafloor -263 NS: Apply Sikafloor -263 SL: self levelling floor topping to primed or unprimed substrate depending on the condition of the substrate. Allow to partially cure and blind surface with kiln dried quartz sand as follows: For a slightly textured, antislip finish: Sikadur -505. For a course-textured finish offering maximum grip: Sikadur -501. Carborundum can also be used for high durability anti-slip finishes. Allow the Sikafloor -263 SL to cure and remove loose sand by vacuum. Apply sealer coat of unfilled Sikafloor -264 (part A + B) by short pile roller. Sikafloor -263 SL/264 Page 2 of 6

The substrate must be clean, dry or saturated surface dry (SSD) and free of all contaminants such as oil, grease, coatings and surface treatments, etc. If in doubt, apply a test area first. Substrate priming is normally not required under typical circumstances. However due to variations in concrete quality, surface conditions, surface preparation and ambient conditions, reference test areas are recommended to determine whether priming is required to prevent the possibility of blisters, debonding pinholes and other aesthetic variations. Sikafloor -PurCem can be applied onto recent concrete over 7 to 10 days old or onto old damp concrete (SSD) without having to prime first, as long as the substrate fulfils the above requirements. Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open textured surface to achieve CSP 3-6 according to the International Concrete Repair Institute. Weak concrete must be removed and surface defects such as blow holes and voids must be fully exposed. High spots can be removed by grinding. All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush and/or vacuum. Substrate imperfections.

Can be filled Edge terminations. All free edges and working day joints of Sikafloor -22 PurCem whether at the perimeter, along gutters or at drains require extra anchorage to distribute mechanical and thermal stresses. This is best achieved by forming or cutting grooves in the concrete. Grooves must have a depth and width of twice the thickness of the Sikafloor -PurCem. Refer to the edge details provided in the Method Statement. If necessary, protect all free edges with mechanically attached metal strips. Never featheredge, always turn into an anchor groove. Expansion joints. Expansion joints must be provided in the substrates at the intersection of dissimilar materials. Isolate areas subject to thermal stresses, vibration movements or around load-bearing columns and at vessels sealing rings. Refer to the edge details provided in the Method Statement. Expansion joints already existing in the substrate must be mirrored in the PurCem system. These joints are to re cut and filled using Sikaflex Tank. Polyurethane sealant Application Conditions/Limitations Optimum Substrate Temperature Optimum Ambient Temperature Substrate Humidity Relative Air Humidity Dew Point +10 C min. / +30 C max. +10 C min. / +30 C max. *note - product can be installed down+2 degrees C however cure times will be significantly slower The substrate can be dry or damp with no free standing water (saturated surface dry or SSD). If any moisture is detectable according to ASTM D 4263 (Polyethylene sheet test) for the thin screeds (-21, -22) and the coating (-31), additional tests must be done to quantify actual relative moisture content amount or vapour drive. Refer to System Structure and options for substrate priming. 85% max. Beware of condensation! The substrate and uncured floor must be at least 3 C above dew point to reduce the risk of condensation or blooming on the floor finish. Application Instructions Mixing Time Prior to mixing, add pigment to part A. Stir Part A well and empty into a clean mixing drum. Add the pigment and Part B and mix both liquid parts thoroughly with a low speed electric stirrer for one (1) minute until a uniform mix has been achieved. Then gradually add Part C (aggregate) to the mixed resin parts and mix for a further one (1) minute, until a uniform moist mix is obtained. Mixing Tools Use a low speed electric stirrer (300-400 rpm) for mixing parts A and B. For preparation of the mortar mix use a pan type revolving mixer. Application Method / Tools Prior to application, confirm substrate moisture content, r.h. and dew point. Priming: Neither priming or applying a scratch coat are usually necessary. (See Substrate Quality) Body coat. Pour the mixed Sikafloor -21 PurCem onto the substrate and work with a trowel or pin screed to the desired thickness, achieving a flat surface. Take care to spread newly placed materials across the transition of previously applied mixes before the surface begins to set. Remove air with a spike roller immediately (less than two minutes). Sikafloor -21 PurCem requires aggregate broadcast onto the wet surface. Broadcast selected aggregates onto the wet surface to excess. Remove excess broadcast aggregate by broom then vacuum. This can be carried out as soon as the base is cured sufficiently - approx 4-6 hours depending on Sikafloor -22 PurCem 6/8

Cleaning of Tools substrate and ambient temperatures Finish Coat. Apply Sikafloor -31 PurCem by pouring out then squeegee or steel trowel the product into the aggregate profile. Excess product can be immediately removed by roller to give the required finish surface profile. Important notes ; Discard mixing buckets every 2-4 mixes depending on ambient temp. Product must be placed on the floor immediately after mixing Subsequent mixes must be placed in a continuous fashion to ensure the joining of the wet edge is timely. Failure to apply Sikafloor -31 PurCem in a timely and continuous process will result in uneven texture, gloss level and colour. Clean all tools and application equipment with Thinner C immediately after use. Hardened / cured material can only be mechanically removed. Pot life Refer to individual TDS for Sikafloor 21 PurCem and Sikafloor -31 PurCem Waiting Time / Overcoating Top coat application - Sikafloor -31 PurCem to Sikafloor -21 PurCem Degrees Time Approx. 15 6-7 hours 20 5-6 hours 25 4-5 hours 30 3-4 hours Note: Times are approximate and will be affected be changing ambient and substrate conditions, particularly temperature and relative humidity. Notes on Application / Limitations Construction joints require pre-treatment with a scratch coat to verify and seal loss of material through the joint. It is advisable to perform a groove along the perimeter of the application area particularly if there are columns or gullies in the floor surface, as indicated in the application details of the Method Statement for Application, to prevent curling during curing. Large areas do require perimeter groove. Width and depth must be twice the thickness of the floor finish. Do not featheredge. Do not apply to PCC (polymer modified cement mortars) that may expand when sealed with an impervious resin." Do not apply to water soaked, glistening wet concrete substrates. Do not apply to porous surfaces where significant moisture vapour transmission (out-gassing) will occur during application. Sika Thinner C is flammable. NO NAKED FLAMES. Always ensure good ventilation when using Sikafloor -22 PurCem in a confined space, to prevent excessive ambient humidity. After application, Sikafloor -22 PurCem must be protected from damp, condensation and direct water contact (rain) for 24 hours. Hot steam cleaning may lead to delamination due to thermal shock. Do not apply to un-reinforced sand cement screeds, asphaltic or bituminous substrate, glazed tile or non-porous brick, tile and magnesite, copper, aluminium, soft wood or urethane composition, elastomeric membrane and fibre reinforced polyester (FRP) composites. Do not apply to wet or green concrete or polymer modified patches if the moisture content is above 10%. Do not apply to concrete if the air or substrate temperature is within 3ºC of the dew point. Protect the substrate during application from condensation from pipes or any overhead leaks. Do not mix Sikafloor -PurCem products by hand. Use only mechanical means. Do not apply to cracked or unsound substrates. Sikafloor -22 PurCem 7/8

Colour uniformity can not be completely guaranteed from batch to batch (numbered). Take care when using Sikafloor -PurCem products to draw from inventory in batch number sequence. Do not mix batch numbers in a single floor area. Products of the Sikafloor -PurCem product range are subject to yellowing when exposed to UV radiation. There are no measurable losses of other properties when this occurs and it is a purely aesthetical matter. Products can be used outside provided the change in appearance is acceptable by the customer. Good towelling and levelling prior to broadcast will result better surface appearance (reduced waviness) and more homogeneous aspect of the seal coat.
