Marble is the soft stone from the sedimentation of lime. The crystallization process should be done to make the marble more strong and shine and flashed. But, it needs to do the crystallization process again, through two ways below:
Covered the pore of the marble with marble powder 47 to make the marble is more flashed.
Covered the pore of the marble with thin film layer in order to make the surface of the layer more flashed
Usually it used acrilyc 47 layer. Both of these steps are effective, but there are two differences. The Compacting process is more long endured, but the process needs more time. The Coating process is more quickly, but it does not long endured. Both of them have superiority, it depends us will choose which one.
