MIXING

Add water according to the desired consistency into a clean mixing vessel before slowly adding the SikaRep® N powder. SikaRep® N is best mixed in a forced action mixer, for 2 to 3 minutes or until the mix is free of lumps, not longer than 5 minutes. Slow speed drill (maximum 500 rpm) can be also used for mixing. Normal tumble type concrete mixers are not suitable. Do not mix more grout than can be placed within 15 to 20 minutes. Do not add extra water or other ingredients. Mix only full bags for the best result.

APPLICATION

Apply SikaRep® N while the bonding agent is still wet. The mortar can be applied by spatula or trowel.
For any thickness greater than 30 mm, SikaRep® N must be applied in several layers.
As soon as the mortar has started to set it can be smoothed by wooden or synthetic float, styrofoam block or sponge. For fine surface finish SikaRep® Fine-N, Sika®Rep Fine-PC® can be applied over the SikaRep® N.

CLEANING OF EQUIPMENT

Application and mixing tools should be cleaned with water while the material is still fresh. Hardened material can only be removed mechanically.
