If you are a beginner and trying to find the most straightforward tips for starting your grinding and polishing tasks for different types of stones and countertops, here is everything you need to get going.

Learning the Basics

You strive for a smooth finish with grinding by smoothing out rough areas or sharp edges. While polishing, your purpose is to create a narrow point or a sharp edge, not the other way around.

A general rule before beginning to grind and polish is to clean. Cleaning stones and countertops beforehand display accurate imagery of the scratches, specifically how serious they are. You can see how deep the polishing should be and determine what procedures would work best.

Wet and Dry 

Wet or dry grinding, honing, and polishing are all possible. Diamond tooling made for wet use, on the other hand, can practically never be used dry, but specific dry tooling can.

A variable-speed polisher is not required for wet processing, but it does provide you with more control. Dry processing necessitates using a variable-speed polisher since tooling speed affects the cutting rate, pad temperature, and finish quality. Furthermore, dust extraction should always be used when dry polishing, with equipment suited to manage fine concrete dust. Crystalline silica dust is extremely harmful to one's health.

Wet processing is faster, produces superior results at all grit levels, and produces no dust. Dry processing has the advantage of not generating a lot of wet mess; thus, it may be done inside a house with powerful dust collection. Dry polishing also produces a higher amount of gloss.

Do Not Skip the Grits

One of the most basic rules is not to skip the grits, regardless of the appearance you want or whether you complete one or more stages. The purpose of each grit in the series is to smooth away scratches from the preceding one. No matter how long you grind, a 3,000-grit pad will not be able to smooth out scratches from a 200-grit place. 

Work your way through the grits, starting with the coarsest and ending with the finest. Do not be tempted to cut corners by missing a grit to save a few minutes. To eliminate the scratches caused by previous grit, you must go through finer and finer grits. With each grit size, the idea is for the scratches to get finer and finer until they are no longer visible. Skipping a grit results in significant scratches in the final polish.

Take Your Time and Be Observant

To secure the results you want, you must be patient. You have to go through every single detail and not miss anything. Remember, your aim is for a polished look for your stones and countertops.
