Application steps

MIXING

SikaRep® Fine N can be mixed with a low speed (< 500 rpm) hand drill mixer or using a force action mixer.

Pour the recommended water in a suitable, clean mixing container. While stirring slowly, add the powder to the water and mix thoroughly at least for 3 minutes to acheive required homogeneous consistency. The obtained mix should be very creamy, easily spreadable and thixotropic.

Do not add extra water or other ingredients after mixing. Normal tumble type concrete mixers are not suitable. Do not mix more material than can be placed within its pot life.

APPLICATION

SikaRep® Fine N 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, XPS block or sponge. No additional water should 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 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.
