How to Cut, Polish, and Seal Granite Countertops

Introduction

If you’re considering adding granite countertops to your kitchen, you’ll need to know how to cut them to size. In this blog post, we’ll walk you through the process of cutting, polishing, and sealing granite countertops with links to posts with more expanded instructions. We’ll also provide some tips on how to maintain your countertops so they always look their best.

Cutting granite countertops

Cutting granite requires the right tools and techniques for accurate results. Here is an step-by-step guide on how to cut granite:

Protect the granite surface with clear plastic that is made to stick to surface. Granite dust if cutting dry or sludge if cutting wet will scratch the granite. Top polishing granite to original factory finish is not a simple or easy process so avoid this at all costs. Measure and mark the desired cut line on the plastic with a medium tip paint pen in opposite shade of granite, if dark use a white or silver paint pen, if light shade use a blue or yellow, black can be used but lining up the blade is harder with black because the reflection is not good.

Set up a stable workspace and secure the granite slab if need be. A large piece has enough mass that won’t need secured.

Attach a diamond blade to a circular saw or wet saw. There are granite/quartz specific saws 5″ and 7″. By the way, 8″ diamond blades will fit a 7″ saw with a little finesse. When using a traditional circular saw you need to protect the granite surface with acrylic plastic to run the saw on even though you have the clear plastic film on the granite. You can use a couple layers of blue painter’s tape or duct tape on bottom of saw but the acrylic plastic will yield best results. Use a straight 2×4 or 2×6 as a gate to help guide the saw and secure with clamps. With blade up slide the saw along your marked line to be sure your wood gate is properly positioned.

If you plan on working with granite more than once or if you have a fairly large job you should consider buying a granite specific rail saw to make your cutting much easier. The rail has rubber on underside of rails so you won’t need the acrylic,just the plastic film we discussed earlier will be needed. The rails can be secured easily and are perfectly straight.

Put on safety goggles, ear protection (you need it) and if cutting dry a dust respirator.

 Start cutting along the marked line, applying even pressure only cutting roughly 3/8″ deep at a time (step cutting) keeping blade cool with water. Keep in mind a dry blade will cut wet but a wet blade won’t cut dry without risking ruining the blade.

Take your time and make slow, steady cuts.

Clean the cut edge and inspect for accuracy.

Next step is Shaping and Polishing the Granite.

Tools and Materials

In order to cut granite countertops, you will need a few tools and materials. First, you will need a saw. There are many different types of saws that can be used to cut granite, but a diamond blade wet saw is the best option. You will also need a measuring tape, a level, and template of actual size of finished piece.

In terms of materials, you will need granite adhesive, caulk, silicone sealant, epoxy, putty knife, and rags.

Granite Countertop Thickness

When it comes to cutting granite countertops, thickness is an important factor to consider. The average thickness of granite countertops is between 3/4 to 1-1/4 inches. Prices for the thinner granite will usually be less than the thicker whether you’re buying raw slabs or paying a fabricator to make the tops for you.

Polishing the Edges

After you have cut the granite countertops to your desired size and shape, you will need to polish the edges. This can be done with a variety of different tools including variable speed polisher/grinder, diamond polishing pads, shaping tools, or a router and polishing wheels. Complete Instructions

Sealing Granite Countertops

Why Seal Granite Countertops

One of the most important things you can do to maintain your granite countertops is to seal them on a regular basis. Granite is a porous material, which means that it can absorb liquids and stains if it is not properly sealed. Sealing your granite countertops will help to protect them from spills, stains, and everyday wear and tear.

How to Seal Granite Countertops

Sealing your granite countertops is a simple process that only takes a few minutes to complete. You will need to purchase a quality granite sealer from your local home improvement store or online retailer. To understand which sealer you need and the complete process, simply Follow the Instructions in this Expanded Post.

How Often to Seal Granite Countertops

You should be sealing your granite countertops at least once every 12 months, although more frequently may be necessary if they are used heavily on a daily basis. There are a number of higher quality sealers available that can last many years longer. If you are unsure whether or not your countertops need to be resealed, simply place a drop of water on the surface of the stone; if the water beads up and does not absorb into the stone, then it does not need to be resealed at this time. Complete Sealing Instructions can be found HERE.

Maintaining Granite Countertops

How to Clean Granite Countertops

It is important to clean granite countertops regularly in order to prevent staining and discoloration. Granite is a porous material, so it can absorb spills and stains if they are not cleaned up promptly. The best way to clean granite countertops is with a mild detergent and warm water. Use a soft cloth or sponge to avoid scratching the surface. Rinse the area well after cleaning and dry with a soft cloth. Complete Instructions HERE.

How to Remove Stains from Granite Countertops

If a stain does occur, it is important to treat it immediately. Granite is a porous material, so the longer a stain sits, the more difficult it will be to remove. There are several ways to remove stains from granite, depending on the type of stain:

-For oil-based stains, such as grease or makeup: Blot the area with a paper towel or clean cloth to absorb as much of the spill as possible. Then, apply a small amount of dish soap directly to the stain and scrub with a soft brush or cloth until the stain lifts. Rinse well and dry with a soft cloth.

-For water-based stains, such as coffee or tea: Mix equal parts water and baking soda into a paste and apply it directly to the stain using a soft brush or cloth. Scrub in gentle circular motions until the stain lifts then rinse thoroughly and dry completely.

-For tough or stubborn stains: You may need to use a commercial granite cleaner/polish following the manufacturer’s instructions. Be sure to test any cleaner in an inconspicuous area first before using it on the entire surface.

How to Prevent Damage to Granite Countertops

Granite countertops are durable and long lasting, but they can still be damaged if not properly cared for. To prevent damage:

-Avoid placing hot pots or pans directly on the surface; always use trivets or hot pads instead

-Use cutting boards when chopping food; never cut food directly on the countertop

-Wipe up spills promptly; do not let liquids sit on the surface for too long

-Avoid using harsh chemicals or abrasive cleaners; these can damage the sealer and in turn the finish.

-Have your countertops sealed every 6 months – 1 year by a professional to prevent staining. You can seal yourself, it is quite simple once you know how and a proper sealer will last many years longer.

Conclusion

In conclusion, cutting, polishing, and sealing granite countertops is not as difficult as it may seem. With the right tools and materials, you can easily cut and polish the edges of your granite countertops. It does take a bit of practice to become proficient with the process so practicing on scrap pieces is highly recommended.  Additionally, sealing your granite countertops will help to protect them from stains and damage. Finally, regular cleaning and maintenance will help keep your granite countertops looking like new for years to come.
