Higher impact velocity induced the droplet to spread faster and has a bigger diameter. At high impact velocity, spreading factor cannot be determined due to splashing and droplet break ups. In addition, at 1.5 m/s the phenomenon of splashing was found to be almost absent except on the surface with {\^a}??square{\^a}?? texture. {\^a}??Square{\^a}?? surface tends to splash earlier compared to other surfaces and is followed by {\^a}??triangle{\^a}??, {\^a}??curve{\^a}?? and smooth surface. At low impact velocity, the smooth surface has the highest spreading factor and followed by {\^a}??triangle{\^a}??, {\^a}??square{\^a}?? and {\^a}??curve{\^a}?? surface. {\^A}{\copyright} 2014 Trans Tech Publications, Switzerland.} }
