Θέμα: polishing granite

[Mike Marinis <favorable_omen@zzzzzzzz>]

There are 2 details I'm sure you as most people miss.
Do the following:

1) polish with water angle grinder

2) 2000 to 4000 RPM are almost the same. Not less (you extend unnessecarily the time ypou must work). Not more (the biotite "burn" effect may be more posible to happen with blur-not shine results)

3) Use little water flow. As much as not become edge dry, as low as not wet yourself.

4) Very Very important!!! Use hard rubber pad if you have no this item, fix it, i have fixed my own. Not rigid steel, neither soft foam pad. Steel pads polish flat surfaces but needs very very skilled use to keep exactly 90 degrees angle. In curves, metal  rigid pads are very difficult to use, it is like you try to paint a surface with a 0.5 pencil.Foam pads become curved to pressure and leave middle part of flat surfaces  bad polished! Hard Rubber pads does perfect for all purposes, curves or flat parts.

5) For perfect results you need to spent more time in grits 200,800 and 3000

6) Pressure of pad must be normal. 1-2 times the weight of grinder.

7) Wher buff press more the grinder to develop heat. Increasing RPM, or cut water flow will not help. Just press pad more.

Do the above and  you will get the best result that it will not match polished machine result but it will be very very close.

Thank you for you time
Mike
