So, total price for mosaic tiles is 1k for 25 ft2. That means RM40 psf. If the mosaic tiles themselves are RM20 psf, means the tiling workmanship is RM20 psf. I think that's very high for the workmanship!
Ya lo, rm20 psf tiling workmanship if u employ chinese worker. For indonesian is cheaper. But not everyone prefer indonesian's work.

Added on June 18, 2009, 5:43 pmMany people plan to choose tiles for their countertop, but most people do not realize that concrete is porous. In fact, more porous than Swiss cheese! The pores constitute 12 to 18% of the concrete but the pores are invisible, much smaller that human hair. After concrete is poured, almost a half of the water has to evaporate. As this surplus water pushes to the surface, it leaves behind a network of capillaries (pores) inside the concrete.
The pores are much larger than water molecules. Water vapor or gases flow easily right through, drawn in by the lower pressure inside buildings. But liquid water is initially held back by its surface tension, as the glob of water gets stuck inside the microscopic dry pore. However, as water enlarges the pores or they get wet by condensation, water starts seeping in. And eventually, the pores start actively pulling in water by capillary action.
Concrete blocks, particularly cinder blocks, are more permeable to water vapor than poured concrete. They all start as impermeable to liquid water but, when exposed to water, their porosity increases and they start seeping water.
2 to 3 years later, if you are using 2x2 tiles, the problem above may occur.
You can choose smaller tiles to avoid this problem. Anyway, granite still will be the best choice for now.
