MIXING

Add water according to the desired consistency into a clean mixing vessel before slowly adding the SikaMur®-100 Blockfix BH powder. SikaMur®-100 Blockfix BH is best mixed in a forced action mixer, for 2 to 3 minutes or until the mix is free of lumps. Slow speed drill (maximum 500 rpm) can be also used for mixing. Normal tumble type concrete mixers are not suitable. Do not add extra water or other ingredients. Mix only full bags for best results.

Note: In hot weather application, use chilled water to extend the open time of the mixed materials.

APPLICATION

Apply the SikaMur®-100 Blockfix BH by trowel. Place the block on mortar ensuring good contact. Check the level and continue with next block. Tool mortar joints when the surface is thumb print hard. Protect newly applied mortar from sun and wind. After setting of SikaMur®-100 Blockfix BH, curing with water will help to gain better strength.
