How to Choose the Best Granite Sealer

Granite sealers are used for a variety of projects that include stone, tile, or granite. These sealers help you keep whatever material you use safe from wear and tear. Things like water-stains and weather-damage can be prevented by using a granite sealer, too! Want to know the best part? Granite sealers can be used almost anywhere, inside or out. They also make cleanup easier in case a mess occurs. But there are a few things you should consider before choosing the best sealer for your project:

Best Granite Sealers

Application Method: Depending on the project you’re tackling, you may need a sealer with a specific kind of application method. Application methods that are common in granite sealers include sprays and squeeze tubes. Some may require extra tools such as a paint brush or towel to apply.

Best Granite Sealers

Package Size: The size of your project can also be a determining factor in how much sealer you will need. Look for a sealer that will cover the entirety of your project to avoid spending extra cash on sealer you won’t use.

How to Choose the Best Granite Sealer

Water Based: Granite sealers that are water based only coat the surface of your project, while oil based sealers penetrate the first layer under the surface to prevent cracking or expansion during seasonal temperature changes. Water based sealers may be best for inside projects, while oil based sealers may work better for outdoor projects.

Best Granite Sealers

Finish: If you’re going for a certain look, one of your highest priorities may be the finish. A high gloss granite sealer will give your project a shiny finish, while a matte finish will give it a flat look.

Best Granite Sealers

Food Safe: If you choose to apply your sealer near or on an eating surface, you may be concerned with the safety of your food on the newly sealed counter or table. Always check to see if the sealer you’ve chosen is food safe if you plan to serve food on or near these areas.

Streak Free: No one likes to see streaks on their newly finished countertop or floor! If you’re looking to have a clean and clear finish, you should be on the lookout for a streak free formula!

Granite Gold Sealer Spray

Review
Granite Gold has been in the stone care industry for over 50 years. Their Sealer Spray gives you 24 ounces of sealant to work with, but for maximum protection Granite Gold suggests you add a second or third coat after each application dries.

This coat provides protection against all spills and messes, but you may find that after drying there are a few streaks left on your countertop. This formula is biodegradable, pH balanced, and food-safe for any of your food prep areas you plan to seal. To apply Granite Gold correctly, be sure you spray your project in 3-foot sections and immediately wipe off with a lint-free cloth. Again, if you are looking for maximum protection do this 2-3 times! Granite Gold Sealer is a good granite sealer if you’re looking for maximum protection in just a few basic coats!
