Top 7 Best Granite Sealer Reviews


All the modern kitchen contains expensive granite marble which is very elegant and beautiful. To keep their integrity and shine intact you would need to take proper care of them.

During food preparations and daily activity, the oil and moisture may get sip into the marble. This reduces the natural shine and smoothness of the stone. If this problem isn’t resolved then the marble may lose its structural integrity and sometimes ends up with permanent stains.

At a situation like this, the granite sealer becomes your best choice. Basically, granite sealer uses a chemical that bonds with the surface to be protected and doesn’t let any stains or oil sip into the marble.

1. Tuff Duck Granite Sealer

Tuff Duck Granite Sealer

There so many granite sealers are available in the market but nothing works like a tuff duck. Tuff duck may seem like a funny name but once you get past the name it provides protection for all kinds of surfaces including Granite, Grout, Marble, Travertine, Limestone, Slate, and even Concrete!

One of the best thing about this penetrating sealer is that its non-acidic sealer formula will not affect the natural looks of your stone tile or countertop.

The Tuff duck sealer boasts twice the active ingredients compared to leading sealer manufacturers to ensure the proper sealing and protection with the single coat.

This sealer protects the interior surfaces up to 5 years while for exterior surfaces the sealer lasts up to 3 years.
A single quart of this sealer will cover up to 800 square feet and on top of that, it is formulated with advanced, water-based fluoropolymers.

The tuff duck is compatible with most of the surfaces like marble, granite, limestone, slate, terrazzo, travertine, sandstone and other porous stone surfaces as well.

Also, the sealing process is easy too. To seal your grout lines just pour this sealer into a bowl, sock the sealer into a sponge and paint on the grout lines. And after sometime wipe it off and you are good to go.

However, the sealer emanates strong smell when being applied so if you have any pets in the home then I would suggest you keep them outside while applying the sealer.

Also, you need to wipe off the sealer after some time which is very time consuming and furthermore if you don’t wipe off the sealer after application then it might leave a white residue.

  • Excellent for sealing almost any surface
  • The stains of soap and water clean off easily after using tuff duck on the quartzite countertop of bathroom
  • Affordable price range and available in different sizes
  • It protects interior surface up to 5 years and exterior surfaces up to 3 years.
  • The single coat will cover up to 800 square feet

  • Strong smell when being applied (not a major issue)
  • Wiping sealer after some time becomes time-consuming

2. TriNova Granite Sealer

TriNova Granite Sealer

TriNova granite sealer is our step-up pick because of its quality features. This granite sealer provides protection for premium surfaces as well as marble.

The two in one Trinova can be used as a sealer as well as a protectant for all surfaces like Quartz, Marble, Granite, Quartzite, and Soapstone.

The advanced and powerful blend of polymers easily penetrates the porous surface and thus gives a protective layer to granite to protect it from water spots and other residue marks.

As I said earlier, this product can be used as a sealer as well as a protectant. You can use this sealer to protect any type of surface against hard to remove stains while the protectant becomes useful when it comes to polishing the surface.

This sealer helps in protecting the countertop and surfaces of bathrooms from unavoidable stains from soap stains and food oils.

It comes with an 18 Oz of sealing agent liquid and one of the best features is that the bottle incorporates extra-long tube so the sealing agent will be able to reach all corners easily.

In order to use the sealer just bend the tube and screw the nozzle. Also to ensure that you have used every last drop of sealer, you can tilt the bottle.

The only downside of this sealer is its price. The product is a little bit pricer compared to the average sealers and expected wear is about 1 year.

But I would say that considering its features, the product is reasonably priced. It is long lasting quick apply and dry sealer which will save you time and trouble to reapplying the sealer again and again.

  • Quick apply and dry sealer
  • Works on almost any surfaces
  • Dual application (Sealer and protectant)
