Surface Preparation


  • 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®-151.
  • 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) using a low speed single paddle electric stirrer (300–400 rpm).
  • Add part B (hardener) to part A and mix part A + B continuously for 3 minutes until a uniform mix has been achieved. When parts A and B have been mixed.
  • Using a double paddle (axis) electric stirrer (>700 W), pan type revolving or forced action mixer or other suitable equipment (free fall mixers must not be used).
  • If required, gradually add the appropriate granulometry of dried quartz sand and if required Extender T.
  • Mix for a further 2 minutes until a uniform mix has been achieved.
  • To ensure thorough mixing pour materials into another container and mix again 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 flat or straight edge trowel at least once to ensure complete mixing.
  • Mix full units only. Mixing time for A+B+quartz sand = 5 minutes.



Application


  • Strictly follow application 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®-151 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 primer waiting/overcoating time has been achieved before applying subsequent products. Refer to individual primer Product Data Sheet.

Levelling Mortar

  • Apply the levelling mortar by squeegee/trowel to the required thickness.

Intermediate Layer

  • Pour mixed Sikafloor®-151 onto the prepared substrate and spread evenly using a serrated trowel to the required thickness.
  • Roll immediately in two directions at right angles to each other with a spiked roller to ensure even thickness and if required broadcast with quartz sand.
  • Broadcast between ≥ 15 minutes minimum, ≤ 30 minutes maximum (at +20°C), lightly at first and then to excess.

Bonding Bridge

  • Pour mixed Sikafloor®-151 onto the prepared substrate and apply by brush, roller or squeegee.
  • For epoxy screed, 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.

Epoxy Screed/Repair Mortar

  • Apply the repair or screed mortar onto the “tacky” bonding bridge.
  • For the screed, use levelling battens and screed rails as necessary.
  • After a short waiting time, compact and smoothen the mortar with a trowel.
  • For the screed, a teflon coated power float (~20–90 rpm) is recommended.

Cleaning Of Tools

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



Limitations


  • After application, Sikafloor®-151 must be protected from damp, condensation and direct water contact (rain) for 24 hours.
  • 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.
  • Discard any material over the pot life recommendations.
  • Do not apply on substrates with rising moisture.
  • Sikafloor®-151 mortar screed is not suitable for frequent or permanent contact with water unless sealed.
  • Pre-trials must be carried out for mortar mixes to assess suitable aggregate grain size distribution.
  • For external applications, apply on a falling temperature. If applied during rising temperatures “pin holing” may occur from rising air. These pinholes can be closed after light grinding by applying a scratch coat of Sikafloor®-151 mixed with ~3 % of Sika® Extender T.
