Can You Use Polishing Compound on Quartz Countertops? A Complete Expert Guide

As a home improvement specialist, I‘m often asked if it‘s possible to polish quartz counters that have become worn and scratched from daily use. The short answer is yes – with the proper techniques and compounds, you can absolutely buff quartz to restore its factory finish and luster.

In this comprehensive 2500+ word guide, I‘ll share everything you need to know to effectively polish quartz yourself, from start to finish.

Why Consider Quartz Countertops?

Quartz has surged in popularity in recent years as a durable, low-maintenance alternative to natural stone counters. Made from crushed quartz blended with pigments and resins, quartz rates very highly on key performance criteria:

Property	Quartz	Marble	Granite
Scratch resistance	Excellent 9/10	Poor 3/10	Good 7/10
Stain resistance	Superb 10/10	Moderate 5/10	Very Good 8/10
Heat resistance	Excellent 9/10	Poor 2/10	Good 7/10

Based on my experience, quartz performs extremely well in terms of durability. However, it can still develop minor surface scratches or lose its polished finish over time.

The good news is that you absolutely can restore the factory shine and polish through do-it-yourself buffing and polishing. With a bit of time and elbow grease, I‘ll demonstrate how to make quartz look brand new again!

Popular Quartz Brand Comparison

There are many excellent quartz brands to choose from. Here‘s an overview of some of the most popular options:

Brand	Price Range	Colors	Warranty
Caesarstone	$$$	60+	Lifetime Limited
Cambria	$$$-$$$$	100+	10 years
Silestone	$$	60+	Lifetime Limited

I recommend Caesarstone and Silestone as great mid-range options that offer outstanding durability backed by lifetime warranties. Cambria is exceptional quality but comes at a higher price point.

No matter which brand you select, follow the polishing steps in this guide to keep your quartz counters looking like new. I‘ll go through the process from start to finish.

Step 1 – Clean the Quartz Surface

Before polishing, it‘s imperative to thoroughly clean your quartz. This removes any dirt, dust, grease or grime that could interfere with polishing and result in surface scratches.

Here‘s how to properly clean quartz prior to polishing:

• Mix a pH neutral cleaner (like Method All-Purpose) with warm water in a spray bottle. Avoid alkaline cleaners like bleach.
• Liberally spray down the entire surface and let soak for 2-3 minutes.
• Use a soft microfiber cloth to gently wipe the quartz clean. Do NOT use abrasive scouring pads or paper towels.
• Rinse thoroughly with clean water to remove all cleaner residue.
• Dry completely with a fresh microfiber cloth. Ensure no moisture remains.

Proper cleaning is the first crucial step to ensure a smooth, uniform polish.

Step 2 – Assemble Your Polishing Supplies

To expertly polish your quartz countertops, you‘ll need the following supplies:

• Quartz polishing compound – Use a polish specifically formulated for quartz. I recommend Stonetech Revitalizer or Hope‘s Perfect Countertop Polish.

• Buffing pad – A microfiber or thin foam pad is ideal. I prefer LCD Microfiber Pads. Avoid hard abrasive pads.

• Soft cloths – Have plenty of clean, lint-free microfiber cloths on hand.

• Power buffer (optional) – A rotary buffer like the Porter Cable 7424XP makes polishing much faster. Use care not to apply too much pressure.

• Masking tape – To protect backsplashes, underside edges, etc. by taping off.

• pH Neutral Cleaner – For prep and post-polish cleaning.

• Quartz sealer – Like Miracle Sealants 511 Impregnator to protect the renewed finish.

Gather all supplies and equipment before starting to make the process smooth and efficient.

Step 3 – Tape Off Borders

Use painter‘s masking tape to tape off any backsplashes, underside edges, or other areas you don‘t want to accidentally polish. This keeps the polish and buffing confined to the counter surface.

Apply tape smoothly across any seams or vertical intersections. When taping around sinks, hold the tape taut to prevent creasing. Take care removing tape after polishing to avoid lifting any quartz sealer.

Step 4 – Apply Polish and Buff in Circular Motions

Here is the heart of the polishing process:

• Put a dime-sized amount of quartz polish on your buffing pad and spread it evenly across the surface.
• Keeping the buffing pad flush with the quartz, move it in consistent circular motions. Apply light even pressure.
• Begin working in an area about 2 square feet. Be systematic and focus on small sections at a time.
• Frequently lift pad to reapply polish. Don‘t let pad "drag" on dry quartz.
• Rinse pad often to remove residue buildup.
• Check for enhanced gloss in each section before moving to a fresh area.
• Target scratches with extra polish and light repeated motions.
• After the full counter is complete, rinse thoroughly and dry with clean soft cloths.

Maintaining consistent pressure and motion is crucial for uniform results. Take your time working across the entire quartz surface until the original polish has been restored.

Tip – Use Minimal Pressure

It‘s vital not to apply excessive downward pressure when polishing quartz. Too much force can damage, crack or chip the surface. Let the polishing compound do the work. Think of the buffing pad as gently massaging the quartz.

I recommend no more than 3-5 lbs of pressure – about the same as rubbing a stain out of clothing. Quartz is strong, but not indestructible. Caution here pays off!

Tip – Check Your Progress Frequently

Make sure to stop buffing and visually inspect the quartz surface every few minutes. This allows you to monitor progress and determine if scratches are fading or if additional polish needs to be applied.

Frequently check if the circular motions are yielding a uniform, streak-free finish. If any areas aren‘t glossing up, give them more focus. But avoid over-polishing sections that already have adequate luster restored.

Tip – Clean and Reapply Polish Often

When polishing a full countertop, don‘t expect one application of polish to do the trick. Plan on reapplying compound every 2-3 square feet. Frequently rinse and dry your buffing pad to avoid spreading dirty residue.

Removing buildup also helps ensure the polishing compound remains evenly distributed and effective. The more regularly you clean and reapply, the better the results.

Be Careful on Quartz Edges

Special care should be taken when polishing edges of a quartz countertop. Avoid applying direct perpendicular pressure along the edge. Instead, work on edges with vertical movements or by tilting the buffer to come across at a 45 degree angle.

Too much direct pressure on the corners and edge seams can damage quartz. Take extra precautions in these vulnerable areas.

Troubleshooting Polishing Problems

Here are some common polishing problems and solutions:

Cloudy Appearance: Usually indicates chemical damage from cleaners or etching agents. Try re-polishing with a buffing compound followed by a quartz-specific sealer. Ensure pH neutral cleaners only are used.

Severe Scratches: Deep scratches may require a professional refinishing. But try making several gentle polishing passes using minimal pressure before considering pro help.

Discoloration/Etching: Caused by acidic substances like wine, juice or harsh cleaners. Can attempt to minimize with polish but full removal may not be possible without a pro.

Chalky/Dull Finish: Generally means regular maintenance is overdue. Clean well with pH neutral cleaner and re-apply polish to restore luster.

Be cautious of pressure and heat when encountering any issues. Damaging quartz further will only add to problems. Consult a professional for major repairs.

Maintaining the Polish on Quartz

To keep your quartz counters looking newly polished for years to come:

• Use trivets and hot pads under hot pans, dishes.
• Clean up spills immediately – especially oil and acidic substances.
• Avoid exposing quartz to harsh cleaners or chemicals.
• Use cutting boards for food prep instead of cutting directly on quartz.
• Apply quartz sealer every 1-2 years per manufacturer instructions.
• Gently polish periodically with quartz compound to maintain gloss.

Follow these tips and your counters will stay beautiful with minimal upkeep required!

Quarts vs. Granite – Which is Easier to Polish?

How does quartz compare to granite in terms of polishing difficulty? Based on working extensively with both materials, quartz is generally much easier to achieve a smooth polished finish on for these reasons:

• Quartz has a uniform manmade composition while natural granite has extreme variances in veining, pits, and density.

• Polishing compound glides evenly over quartz but tends to get trapped in granite pores and crevices.

• Quartz rates 7 on the Mohs hardness scale making it slightly softer than granite which ranks 6-7.

• Granite can stain while quartz‘s non-porous surface resists absorbing stains which hamper polishing.

• There are polishes specifically formulated for quartz while granite may require diamond abrasives.

Bottom line – quartz will polish up faster and with less effort than granite. But as with any stone surface, exercise great care and caution when polishing. Consider hiring a professional if repairing deep damage.

To Hire a Pro or DIY?

You may be wondering if it‘s worth hiring a professional quartz restoration company vs polishing yourself. Here are some pros and cons to consider:

Benefits of Professional Polishing:

• Access to special equipment like high speed floor buffers for faster results

• Professionals can repair severe damage like deep scratches that are beyond DIY methods

• They have expertise on the most effective polishing techniques and compounds for your specific quartz type and finish

• Results will typically have a very uniform smoothness across the entire surface

Downsides of Professional Polishing:

• Cost will be higher – from $200 up to polish an average sized countertop area

• You need to arrange your schedule around appointment times instead of tackling whenever convenient

• Risk of inexperienced companies further damaging the quartz surface if not cautious

For minor surface level scratches and wear, DIY polishing often makes sense. But if your counters have significant damage or you want them looking perfect, consulting a pro may be worth the price.

With a deliberate, careful approach, polishing compound can safely be used to buff out minor scratches in quartz and restore its glossy just-installed finish. Focus on using specialized quartz polish, minimal pressure, frequent compound reapplication, and consistent circular motions across the entire surface. Bear in mind edges and seams need extra precautions not to chip.

I hope these comprehensive tips give you the confidence to take on polishing your quartz counters yourself. Just be patient, take it slow, and follow the techniques outlined to achieve professional-level results. Let me know if you have any other questions!
