Reactive acrylic resins

From date of production:

Sikafloor® -Pronto Hardener must be protected from heat, direct sunlight, moisture and impact.

The packagings must be stored properly in original, unopened and undamaged sealed packaging, in dry conditions at temperatures between +5°C and +30°C.

~ 100% (by volume) / ~ 100% (by weight)

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

Short-term 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®-14 / -16 or - 15 or -32 / -18 Pronto as a broadcast system with approx. 3 - 4 mm thickness.

Part A: Pigment = 9 : 1 (by weight)

The amount of Hardener required to be added on 9 kg Sikafloor®-18 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“

0°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.

0°C min. / +30°C max.

Before overcoating Sikafloor®-18 Pronto allow:

~ 0.6-0.8 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-28, Sikafloor® Pronto RB-55, Sikafloor® Pronto RB-58.

Mix part A thoroughly, then add the Hardener in the correct quantity and mix for further 1 minute.
Pigmented: Mix part A thoroughly. Premix the required amount of Sika® Pronto Pigment with the same quantity of part A by dissolver.
After that, mix part A and the obtained pigment paste with mixing ratio of 4 : 1 to get the final seal coat (overall content of Sika® Pronto Pigment in the final seal coat = 10%) for at least 3 minutes. Then, add the hardener in the correct quantity and mix for further 1
minute.
Over mixing must be avoided to minimise air entrainment. For easy of handling, 25 kg units may be split (please refer to mixing table).
Always weight out components.
Mixing Tools: For indoor work, spark-free mixing equipment must be used (explosion-proof)!
Sikafloor®-18 Pronto must be thoroughly mixed using a low speed electric stirrer (300 - 400 rpm) or other suitable equipment. For the preparation of the pigment powder, a dissolver must be used.

Prior to application confirm 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.

Seal coat:
Immediately after mixing, pour the Sikafloor®-18 Pronto onto the substrate and spread evenly by means of a “non-fuzzing” short-pile nylon roller or squeegee and then back-rolled (crosswise) with a short-piled roller.
A seamless finish can be achieved if a ‘wet’ edge is maintained during application.

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