Pre-wet the existing concrete surface to a SSD condition prior to application of micro concrete. In order to prevent air voids apply mixed EXCEM-MC60 from one side or corner only. EXCEM MC60 should be placed within half an hour of mixing. During that time keep material in mixer well agitated. After half an hour discard any mix that shows signs of stiffening. Flowable mix may be used with low pressure cement grouting equipment or may be hand rodded into restrained sections. High points must be adequately vented to allow entrapped air to escape. Plastic mortar may be rodded into place or trowel handled where freedom of movement permits. Consistency can range from thick cream to smooth plastic. For large volume of placement areas EXCEM – MC60 may be pumped with a heavy duty diaphragm pump, screw or any other standard pump.

EXCEM – MC60 shall be used in the thickness range of 20mm to 100mm in single pour. For thickness of a section is more than 75 mm, 40-60 % (by weight of Excem–MC60) 6-10mm down washed coarse graded aggregate shall be used to reduce temperature built up which may cause crack in the hardened micro concrete. For large flat floor area, 50% aggregate can also be used if the thickness is 50-75mm with glass/aluminium strip in 1.5 -2 m box grid to avoid irregular crack development.
