MIXING
Coatings
- Prior to mixing all parts, mix separately Part A (resin) using an electric single paddle mixer (300 - 400 rpm) or other similar equipment. Mix liquid and all the coloured pigment until a uniform colour / mix has been achieved.
- Add Part B (hardener) to Part A and mix Part A + B continuously for 3.0 minutes until a uniformly coloured mix has been achieved.
- To ensure thorough mixing pour materials into a clean container and mix again for at least 1.0 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 = ~4.0 minutes.
Self-smoothing resin
- 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 3.0 minutes until a uniform mix has been achieved. When Parts A and B have been mixed, using an electric double paddle mixer (> 700 W), pan type revolving, forced action mixer or other similar equipment (free fall mixers must not be used) gradually add the required granulometry of dried quartz sand and if required Sika® Extender T.
- Mix for a further 2.0 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+Sika® Quartz sand = ~5.0 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 and dew point. If > 4 % pbw moisture content, Sikafloor® EpoCem® may be applied as a T.M.B. (temporary moisture barrier) system.
- Refer to the individual System Data Sheet for the applications required.
Primer
- Pour mixed Sikafloor®-161 HC primer onto the prepared substrate and apply by brush, roller or squeegee (most preferred) 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®-161 HC levelling mortar.
- Confirm waiting /overcoating time has been achieved before applying subsequent products. Refer to individual Product Data Sheet.
Coating
- Apply Sikafloor®-264 HC N onto the prepared substrate using a short-piled roller, brush or squeegee in two directions at right angles to each other.
- A seamless finish can be achieved if a ‘wet’ edge is maintained during application.
Self-smoothing wearing layer
- Pour mixed Sikafloor®-264 HC N onto prepared substrate and spread evenly using a suitable trowel or pin leveller to the required thickness.
- Spike roller immediately in two directions at right angles to each other to remove trowel marks, aid air release, ensure an even thickness and obtain the required surface finish.
- A seamless finish can be achieved if a ‘wet’ edge is maintained during application.
Slip-resistant broadcast layer
- Pour mixed Sikafloor®-264 HC N onto prepared substrate and spread evenly using a suitable trowel or pin leveller to the required thickness.
- Spike roller immediately in two directions at right angles to each other to aid air release and ensure an even thickness.
- After about 15 minutes (at +20 °C) but before 30 minutes (at +20 °C), broadcast with quartz sand or silicon carbide, at first lightly and then to excess to produce an even distribution surface profile.
- Allow Sikafloor®-264 HC N to initially cure and remove all loose sand by vacuum extraction equipment.
Seal / Top coat
- After waiting the required overcoating time / curing, pour the mixed Sikafloor®-264 HC N onto the slip resistant broadcast layer and spread evenly using a squeegee at the required consumption rate 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 OF TOOLS
Clean all tools and application equipment with Thinner C or suitable solvent immediately after use. Hardened material can only be removed mechanically.
CLEANING
To maintain the appearance of the floor after application, Sikafloor®-264 HC N 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.
Refer to Sika Method Statement: Sikafloor®-Cleaning Regime.
