How to Choose the Best Marble Sealer

If you’re looking into how to seal marble countertops or floors, you might be looking for the best product to get the job done. We’ve got you covered! We’ve done all the research to present you with the top ten marble sealers on the market right now. First, let’s jump into what you should look for, and afterward check out our amazing list of marble sealing products to keep your stone looking great!

Application Method: There are a few different ways that you can apply a sealer, and most sealers can be applied in any way you prefer. Still, we’ll tell you what type of container it comes in and what the company prefers!

Package Size: How much are you getting? This is important depending on the amount of marble that you need to seal. Don’t buy a gallon if you have a small area, but also don’t buy less than you need for your surface.

Water Based: Water-based sealers don’t have as many harsh chemicals as sealants that are based in petroleum and other chemicals. They are also more prone to being food-safe than polymer-based sealers, but we’ll let you know here.

Finish: The finish can make all the difference on your countertops or floors. Some sealers finish with a high gloss, while some are matte (meaning they don’t change how your marble looks). Choose the one that you prefer!

Food Safe: Is the sealer food safe? Most of them will be after a certain amount of time has passed after application. Still, it’s better to be safe than sorry, so we will tell you here if they are or not.

Streak Free: Streak-free application is the norm for most of these products, which basically means that it’s going to dry clear, without any streaks from whatever application method that you used. This is important to keep your home looking great.
