Application steps

MIXING

Mix part A thoroughly then add the Hardener in the correct quantity and mix for a 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. Mix part A and the obtained pigment powder (overall content of Sika-Pronto Pigment in the mixture = 10%) for at least 3 minutes. Then 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 (refer to Mixing table).
Always weigh out components.

For indoor work, spark-free mixing equipment must be used (explosion-proof)!
Sikafloor-16 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-16 Pronto onto the substrate and spread evenly by means of a “non-fuzzing” shortpile nylon roller or squeegee and then backrolled (crosswise) with a short-piled roller.
A seamless finish can be achieved if a ‘wet’ edge is maintained during application.

CLEANING OF EQUIPMENT

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