2) Wearing safety belts and helmets while working at heights.
3) Wearing safety goggles while chipping of loose concrete.
4) Polyalk EP should be handled carefully using hand gloves.
PURPOSE:
To strengthen the concrete, where said defects are observed.
MATERIALS AND TOOLS:
Polyalk EP Polymeric Mortar Modifier (PMM) of Sunanda Speciality Coatings Pvt.Ltd, Cement, Quartz’s sand, water, chipping tool, wire brush masons trowel, pan for mortar mixing, measuring jar, wooden stick.
