Application steps

MIXING

Mix 25 kg bag with necessary, above mentioned amount of cold water, using an electric blender with a suitable mixing spiral, in a clean bucket. Add the SikaRep® Fine PC powder slowly while mixing continuously for at least 3 minutes and until a homogeneous consistency is achieved.

Use a blender at 500 rpm maximum; do not mix at faster rate because of mechanical strength decay of cured product. The obtained mix results very creamy, easily spreadable and thixotropic.

APPLICATION

SikaRep® Fine PC can be applied by trowel, spatula or wet spray. As soon as the mortar has started to set it can be smoothed by wooden or synthetic float, styrofoam block or sponge. No additional water must be used as it may lead to surface discoloration.

CURING TREATMENT

Where ambient conditions may lead to rapid surface drying, the use of light water fogging for 48 hours or application of a suitable water based curing compound like Sika® Antisol WB is recommended. Do not commence fogging until final set has been reached.

 

CLEANING OF EQUIPMENT

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