Concrete Countertops FAQ
Timing and "feel" are critical in getting a flat, smooth finish. If you are going to grind lightly and polish after the concrete has cured sufficiently (3 to 4 days or less, depending on your cure time and mix design), a flat surface is imperative to avoid tedious grinding to even out the surface. Topical vs. penetrating sealers. Q.

Coffee Grind Size Chart | (Guide For All Brewing Methods!)
Here is a simple 3 point guide on finding the right coffee grind size for any brewing method: Immersion brewing methods such as Cold brew and French press, involve steeping the coffee grounds in water for an extended period. To prevent over-extraction, a coarse grind size is used.
Fine Grinding Considerations
Fine grinding materials--down to the micron, sub-micron, or even into the nano level--is more complex than just reducing particle size. First, knowing and understanding the existing properties of the material to be processed is vital in order to select the right equipment. For example, hardness is one important characteristic to consider, since the type of
