These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc. For detailed info, please refer to the system data sheet Sikafloor® Pronto RB-25, Sikafloor® Pronto RB-27 and Sikafloor® Pronto RB-55.
MIXING
Mix part A thoroughly, then add the Sikafloor®-Pronto Filler, and (if required) the Sika®-Pronto Pigment and mix for at least 1 minute. When the different components are adequately mixed, add the Hardener in the correct quantity and mix for a further 1 minute.
Over mixing must be avoided to minimise air entrainment.
For ease of handling, 25 kg units may be split (2 x 12.5 kg) (refer to Mixing table). Always weigh out components.
Mixing Tools
For indoor work, spark free mixing equipment must be used (explosion-proof)!
Sikafloor®-15 Pronto must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment.
APPLICATION
Prior to application, confirm substrate moisture content, r.h. and dew point.
For external applications, apply on a falling temperature. If applied during rising temperatures “pin holing” may occur from rising air.
Levelling:
Rough surfaces need to be levelled first. Therefore use e.g. Sikafloor®-15 Pronto or Sikadur®-12 Pronto levelling mortar (see PDS). Apply by squeegee / trowel to the required thickness.
Reinforced layer:
Sikafloor®-15 Pronto filled with Sikafloor®-Pronto Filler is poured, spread evenly by means of a serrated trowel. Roll immediately in one direction with a spiked roller to ensure even thickness and to remove entrapped air. Roll out Sika® Reemat Premium into the wet resin, ensuring the complete removal of entrapped air free using a lamb wool roller. Allow a minimum 50mm overlap on all joints of the reinforcement fleece. Apply wet on wet an encapsulation layer of Sikafloor®-15 Pronto filled with Sikafloor®-Pronto Filler using a lamb wool roller or flat spatula to ensure full
saturation of the fleece.
Broadcast base coat:
Sikafloor®-15 Pronto is poured, spread evenly by means of a serrated trowel. Roll immediately in one direction with a spiked roller to ensure even thickness and to
remove entrapped air. Immediately afterwards, broadcast with quartz sand.
Note: Broadcast quartz sand in ca. three steps, which means the first couple of times broadcast slightly, then to excess in order to ensure an even distribution of quartz sand and to avoid misplacing of the material.
A multi coloured surface can be obtained by broadcasting with coloured-quartz.
The material cures very quickly and therefore application must be carried out steadily and “wet on wet” in order to achieve joint free floors.
CLEANING OF TOOLS
Clean all tools and application equipment with Thinner C immediately after use. Hardened and/or cured material can only be removed mechanically.
