Application

SUBSTRATE QUALITY / PRE-TREATMENT
The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. Pull-off strength shall be not less than 1.5 N/mm². The application of a trial area is mandatory to ensure the compatibility of the substrate and the proposed Sikafloor Pronto System, especially when cementitious substrates treated with a curing agent.

All dust, loose and friable material must be completely removed from all surfaces before application of the product, preferably by brush or vacuum.

MIXING 
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 data sheet). Always weigh 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.

APPLICATION
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.
