The Granite Gold Sealer Spray was created to provide a long-lasting seal on granite countertops. The product comes in a flat-bottomed can that can easily be sprayed directly on the countertop surface.
The granular formula, when applied to the countertop, provides a self-sealing protective film on the surface. The formula has a density of 400-500 and it seals edges and joints, preventing water from dripping through the edges and joints of granite countertops.
WHAT WE LIKE
Granite Gold is actually quite soft, so the film is more of a draw and putty product, rather than a thick liquid. It is easy to use; just wet the countertop with water and spray the granular product on.
Wait for the formula to dry on the surface and then buff the edges of the sealer onto the counter.
Granite Gold Sealer Spray is a convenient product to solve various problems related to granite countertops, floors, and walls.
It is a clear sealer that leaves no residue. It is made of a durable material that is free of toxic substances. It is used by professionals, and it is a product that is made to last.
PROS
- Impressive sealing power
- Has a pleasant smell to it
- Safe to use on all food surfaces, non-toxic
CONS
- We couldn’t really find anything bad today about the product. From most reviews, it seems that the customer failed to properly follow the directions on the package. We feel we cannot fault the company for this. The instructions are plain and clear in our opinion.

TriNova’s Granite Sealer has been praised for its performance and ease of use. A powerful yet easy-to-use sealer, TriNova claims to not only fix on-site problems, but also creates a professional finish.
This is a mineral based self-leveling sealer that helps to provide the perfect balance between gloss and shine. A rubber base layer prevents any buildup of the sealer and helps prevent chipping and cracking on the face of your countertop.
WHAT WE LIKE
The sealer has a “removable” base, which helps protect against surface unevenness and bumps, as well as gives you the option to apply additional coats to the surface. TriNova Granite Sealer comes in two different sizes: 18 ounce and one gallon.
Homeowners (especially those who are remodeling) can save money and get professional results when they use the TriNova Granite Sealer. It produces a beautiful, hard-wearing, seamless seal on all granite surfaces, including kitchen countertops, shower stalls, porches, and staircases.
It is perfect for homeowners who are remodeling their homes and want a beautiful result.
PROS
- Can be used on nearly any type of stone surface including marble
- Provides powerful stain protection
- Great Customer Happiness Policy
- One hour cure time
CONS
- Not very good with super porous type stone
- People have a hard time knowing if the product works because they cannot see a difference. At the same time, this is a water-based product, so you won’t likely see anything after applying
- Some customers have reported that they need to use more of the product than expected

- Performs poorly with very porous granite

The Stone Care International Granite Sealer and Protector is a top-rated product for countertops that have cracks or water seeping through. This sealer removes excess water more effectively than some other products such as silicone sealers.

PROS
- Works on multiple types of surfaces
- Applies very easily
- Very good instructions are included
CONS
- Some customers describe this as a ‘Hit or Miss’ product. Some have great results while others have a poor experience. We are not certain if this is because they are not following the instructions or if they are receiving a bad batch of product.

Rock Doctor Granite Sealer has a very simple, and fast, installation procedure. Once your countertop has been cleaned with cleaning wipes, a tube of the Rock Doctor Granite Sealer will be applied to the countertop.
When the granite has been covered, the sealer will dry to a crack-free finish in about 30 minutes. After that, if you apply your favorite sealer to your countertop, it will seal your countertop for up to 30 years.
The only downside to this product is that it requires professional installation and will not be compatible with stains and dents. However, for the average homeowner that doesn’t have access to a granite shaper or mason to install a countertop, this product should be an excellent choice.
