Reactive acrylic resins

From date of production:

The packagings must be stored properly in original, unopened and undamaged sealed packaging, in dry conditions at temperatures between +5°C and +30°C.  Sikafloor® -Pronto Hardener must be protected from heat, direct sunlight, moisture and impact.

~100 %

~100 %

Resistant to many chemicals. Please ask for a detailed chemical resistance table.

Short-term moist/wet heat* up to +80 °C where exposure is only occasional (steam cleaning etc.)
* No simultaneous chemical and mechanical exposure and only in combination with Sikafloor®-11/-18 Pronto as a broadcast system with approx. 3 - 4 mm thickness.

Part A: Part C: Pigment = 12.5 : 25 : 1 (by weight)

The amount of Hardener required to be added on 12.5 kg Sikafloor®-15 Pronto is dependent on the ambient- and substrate temperature.

The hardener powder can also be supplied by Sika under the product name "Perkadox CH 50 X“

+5 °C min. / +30 °C max.

~ 80 % r.h. max.

Beware of condensation!
The substrate and uncured floor must be at least 3°C above dew point to reduce the risk of condensation or blooming on the floor finish.

+5 °C min. / +30 °C max.

≤ 4 % pbw moisture content.
Test method: Sika®-Tramex meter, CM - measurement or Oven-dry-method.
No rising moisture according to ASTM (Polyethylene-Sheet).

Before overcoating Sikafloor®-15 Pronto allow:

~ 3-4 kg/m² depending on the system applied

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.

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.

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.

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