Product Description

Sika Sikafloor® 150 is a 2-part, low odour, low viscosity, multi-purpose epoxy resin which can be used as an epoxy primer, levelling mortar and mortar screed.

Best Uses

Sika Sikafloor® 150 is formulated for the priming of concrete substrates, cement screeds and epoxy mortars as part of a system. Sika Sikafloor® 150 is moisture control on cement-based substrates with moisture contents of ≤ 4 % CM (99 % RH).

Sika Sikafloor® 150 is suitable for normal to strongly absorbent substrates, as a primer for all Sika Epoxy and PUR floorings,  as a binder for levelling mortars and mortar screeds and for substrate consolidation on concrete, cement and anhydrite screeds and refurbished substrates.

  • Low viscosity
  • Low odour
  • Good penetration
  • Good bond strength
  • Suitable for use on underfloor heated screeds
  • Short waiting times
  • Multi-purpose

Sika Sikafloor® 150 may only be used by experienced professionals.

Application

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®-150. 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.

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 (>700W), 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.

Strictly follow installation procedures as defined in information manuals, 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 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®-150 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®-150 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.
