Expert Guide: Best Tools for Sanding Granite

If you’re looking to sand granite, you’ll need the right tools for the job. Granite is a tough and durable stone that requires specialized equipment to properly shape and smooth its surface. Here are some of the best tools for sanding granite:

Diamond Polishing Pads

Diamond polishing pads are a must-have tool for sanding granite. These pads are made of diamond particles that are embedded in a resin or metal matrix. They come in a variety of grits, from coarse to fine, and are used to polish and shape the surface of the stone. Diamond polishing pads can be used wet or dry, and are typically attached to a handheld polisher or angle grinder.

Angle Grinder

An angle grinder is a versatile tool that can be used for a variety of tasks, including sanding granite. When used with a diamond polishing pad, an angle grinder can quickly smooth and shape the surface of the stone. It’s important to use a variable speed angle grinder, as granite is a hard stone that requires lower speeds to avoid overheating and damaging the surface.

Diamond Drum Wheel

A diamond drum wheel is a specialized tool that is used to shape and smooth the edges of granite. The drum wheel is attached to an angle grinder or polisher and is used to remove material from the edge of the stone. Diamond drum wheels come in a variety of sizes and grits, and are typically used wet to prevent overheating and ensure a smooth finish.

Diamond Hand Pads

Diamond hand pads are small, handheld tools that are used for polishing and shaping small areas of granite. They are typically used for touch-up work or for getting into tight spaces that cannot be reached with larger tools. Diamond hand pads come in a variety of grits and can be used wet or dry.


Water is an essential tool for sanding granite. When used with diamond polishing pads or drum wheels, water helps to cool the surface of the stone and prevent overheating. It also helps to remove debris and keep the surface clean, which is important for achieving a smooth finish.

With the right tools and techniques, sanding granite can be a rewarding and satisfying task. Whether you’re a professional stone fabricator or a DIY enthusiast, these tools will help you achieve the results you’re looking for.

The Ultimate Guide to Choosing the Best Sandpaper for Granite

If you’re planning on sanding down some granite, you’ll need the right sandpaper to get the job done. But with so many options available, it can be tough to know which one to choose. In this ultimate guide, we’ll walk you through everything you need to know to choose the best sandpaper for granite.

Understanding Grit

When it comes to sandpaper, grit is king. The grit refers to the number of abrasive particles per square inch of sandpaper. The higher the number, the finer the sandpaper. For granite, you’ll typically want a grit of at least 220, but finer grits can also be used.

Dry vs. Wet Sanding

Another important consideration is whether to use dry or wet sandpaper. Dry sandpaper is best for small projects and for shaping surfaces, while wet sandpaper is ideal for larger projects and for achieving a smoother finish. Wet sandpaper is also less likely to clog with dust and debris, which can help extend its lifespan.

Types of Sandpaper

There are several different types of sandpaper that can be used for granite. Here are a few of the most common:

  • Silicon carbide: This is the most popular type of sandpaper for granite. It’s durable and can be used wet or dry.
  • Diamond: Diamond sandpaper is the most expensive option, but it’s also the most effective. It’s best used wet.
  • Aluminum oxide: This type of sandpaper is affordable and versatile, but it’s not as durable as silicon carbide or diamond.

Choosing the Right Sandpaper

When choosing sandpaper for your granite project, consider the size of the project, the desired finish, and your budget. If you’re working on a large project, wet sandpaper is likely your best bet. If you’re looking for a smooth finish, diamond sandpaper is the way to go. And if you’re on a tight budget, aluminum oxide sandpaper will get the job done.


Choosing the right sandpaper for granite is crucial for achieving a smooth, polished finish. By understanding grit, dry vs. wet sanding, and the different types of sandpaper available, you’ll be able to make an informed decision and get the job done right.

Renew Your Granite: Learn How Sanding and Resealing Can Revive Your Countertops

If you’re tired of your granite countertops looking dull and worn out, you don’t need to spend a fortune on replacing them. Sanding and resealing your granite can give it a new lease on life and make it look as good as new. Here are some tips on how to renew your granite countertops.

Why Renew Your Granite?

Granite is a popular choice for countertops because of its durability and natural beauty. However, over time, it can become dull, scratched, or stained, making it look old and worn out. Renewing your granite can restore its natural shine and make it look like it did when it was first installed.

How to Sand Your Granite

Sanding your granite removes the top layer of the stone, which can be scratched, stained, or dull. You’ll need a diamond sanding pad, which you can find at most home improvement stores. Start with a low-grit sanding pad and work your way up to a higher grit to achieve a smooth finish.

Before you start sanding, clean your countertop thoroughly with a granite cleaner. Then, use a spray bottle to mist the surface with water. This will help the sanding pad glide smoothly over the surface and prevent it from overheating. Work in small sections, using a circular motion, and keep the surface wet at all times.

How to Reseal Your Granite

Resealing your granite protects it from stains and damage and helps it maintain its shine. You can buy a granite sealer at most home improvement stores. Before you start, make sure your countertop is clean and dry.

Apply the sealer evenly to the surface using a soft cloth or brush. Let it sit for 10-15 minutes, then wipe off any excess with a clean cloth. Repeat this process two or three times, allowing each coat to dry completely before applying the next one.

Tips for Maintaining Your Renewed Granite

Once you’ve sanded and resealed your granite, it’s important to take care of it properly to maintain its beauty. Avoid using harsh chemicals or abrasive cleaners, which can scratch the surface. Instead, use a granite cleaner and a soft cloth to clean it regularly. Wipe up spills right away to prevent staining, and use coasters or trivets under hot dishes to prevent heat damage.

Sanding and resealing your granite countertops can give them a new lease on life and make them look like new again. With these simple tips, you can renew your granite and enjoy its natural beauty for years to come.

Grinding Down Granite: What You Need to Know
