    Surface Preparation


    Pre-treatment

    • Cementitious substrates (concrete / screed) must be structurally sound and of sufficient compressive strength (minimum 25 N/mm²) with a minimum tensile strength of 1.5 N/mm².
    • Substrates must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings, laitance, surface treatments and loose friable material.
    • Cementitious substrates must be prepared mechanically using suitable abrasive blast cleaning or planing / scarifying equipment to remove cement laitance and achieve an open textured gripping surface profile suitable for the product thickness.
    • High spots can be removed by grinding.
    • Weak cementitious substrates must be removed and surface defects such as blow holes and voids must be fully exposed.
    • Repairs to the substrate, filling of cracks, blowholes/voids and surface levelling must be carried out using appropriate products from the Sikafloor®, Sikadur® and Sikagard® range of materials. Products must be cured before applying Sikafloor®-2640.
    • All dust, loose and friable material must be completely removed from all surfaces before application of the product and associated system products, preferably by vacuum extraction equipment.

    Mixing

    • Prior to mixing all parts, mix separately Part A (resin) thoroughly using an electric single paddle mixer (300 - 400 rpm) or other suitable equipment.
    • Add Part B (hardener) to Part A and mix Part A + B continuously for 3 minutes until a uniformly consistent mix has been achieved.
    • To ensure thorough mixing, pour materials into a clean container and mix again for at least 1 minute to achieve a smooth consistent mix.
    • Excessive mixing must be avoided to minimise air entrainment.
    • During the final mixing stage, scrape down the sides and bottom of the mixing container with a straight edge trowel or spatula at least once to ensure complete mixing.
    • Mix full units only. Mixing time for A+B = ~4 minutes.



    Application


    • Strictly follow installation procedures as defined in method statements, application manuals and working instructions which must always be adjusted to the actual site conditions.
    • Prior to application, confirm substrate moisture content, relative air humidity, dew point, substrate, air and product temperatures.
    • If moisture content > 4% parts by weight, Sikafloor® EpoCem® may be applied as a Temporary Moisture Barrier (T.M.B.) system.

    Primer

    • Pour mixed Sikafloor®-150 /-161 primer onto the prepared substrate and apply by brush, roller or squeegee then back roller in two directions at right angles to each other.
    • Ensure a continuous, pore free coat covers the substrate.
    • If necessary, apply two priming coats.
    • Confirm waiting /overcoating time has been achieved before applying subsequent products.
    • Refer to individual primer Product Data Sheet.

    Levelling

    • Rough surfaces must be levelled first using Sikafloor®- 150/-161 levelling mortar.
    • Confirm waiting /overcoating time has been achieved before applying subsequent products.
    • Refer to individual Product Data Sheet.

    Textured coating

    • Pour mixed Sikafloor®-2640 onto the prepared substrate and apply using a short-piled roller in two directions at right angles to each other.
    • A seamless finish can be achieved if a ‘wet’ edge is maintained during application.

    Seal coat

    • After waiting the appropriate overcoating time / curing, pour the mixed Sikafloor®-2640 onto the textured coating and spread evenly using a squeegee at the required consumption rate (0.6–0.8 kg/m²) to completely encapsulate the sand.
    • Then using a short-piled roller, back roller in two directions at right angles to each other.
    • A seamless finish can be achieved if a ‘wet’ edge is maintained during application.



    Cleaning


    Cleaning Of Tools

    • Clean all tools and application equipment with Thinner C immediately after use.
    • Hardened material can only be removed mechanically.

    Cleaning

    • To maintain the appearance of the floor after application, Sikafloor®-2640 must have all spillages removed immediately and must be regularly cleaned using rotary brush, mechanical scrubbers, scrubber dryer, high pressure washer, wash and vacuum techniques etc. using suitable detergents and waxes.



    Limitations


    • Do not leave mixed product in container after the end of the pot life. Fill container completely with quartz sand to stop the rapid exothermic reaction of the product which leads to foaming.
    • Do not apply on substrates with rising moisture.
    • Do not blind the primer.
    • After application, product must be protected from damp, condensation and direct water contact for at least 24 hours.
    • For areas with limited exposure and normal absorbent concrete substrates. Priming with Sikafloor®- 150/-161 is not necessary for roller or textured coating systems.
    • If product is used for roller / textured sealer coats. Uneven and / or dirty substrates must not be considered for thin coating application. All areas must always be prepared and cleaned thoroughly prior to application.
    • The incorrect assessment and treatment of cracks may lead to a reduced service life and reflective cracking.
    • For exact colour matching, ensure the Sikafloor®- 2640 in each area is applied from the same control batch numbers.
    • Under certain conditions, underfloor heating or high ambient temperatures combined with high point loading, may lead to indentations in the resin.
    • If temporary heating is required, do not use gas, oil, paraffin or other fossil fuel heaters, these produce large quantities of both CO² and H²O water vapour, which may adversely affect the finish. For heating use only electric powered warm air blower systems.
