How to Seal a Marble Dining Room Table

Our new marble dining table- love it!

As you guys know, we finally have a dining room table. It only took us about 10 months of living in our home to take the plunge and choose one. Can you tell we like to weigh all of our options first?! Ha!

But lo and behold, we finally chose a dining room table and I could not be happier with our purchase! Our marble table is seriously stunning, and these photos do not do it justice. During the entire first week of it being in our home, I’m pretty sure I “pet” it every day while walking by. Yep, weird. But that’s how much I love this baby!

The marble is stunning- now to keep it in this pristine condition

Because my love for this table runs deep, you can bet your bottom dollar that I am going to do everything in my power to keep it looking great for years to come. And because it’s marble…that means that sealing it right away was my top priority!

Why seal marble?

Our marble table, up close

Earlier this year we chatted about the importance of sealing your granite countertops. It’s just as (if not more!) important to seal any marble, or else you’re leaving the porous stone exposed and open to staining and markings. Even something as simple as putting a glass of iced water on an unsealed piece of marble can leave a water ring. No bueno. So it’s really important to properly seal marble and continue to keep up on that seal every couple of years.

The perfect supplies- marble sealer, a sponge and rag

Before the table even arrived, I had already researched dozens of products to find the best one to seal our porous marble. After reading lots of tutorials and reviews, I went with Tuff Duck (which I found on Amazon, because online shopping is the only way I know how these days! #prime)

SuppliesTuff Duck Natural Stone Sealer is my personal favorite

  • Stone Sealer (I used the brand Tuff Duck)
  • Kitchen Sponges
  • Rags
  • Beach Towels (to keep your surrounding surfaces clean from over-spray)

How to Seal Marble

1. First, I wiped off the table with a dry rag and made sure it was squeaky clean.

First, clean your table and protect the floor area below

2. I shook up the bottle of Tuff Duck and put beach towels on the ground where I was going to spray, so it wouldn’t over-spray onto the ground. Then I started spraying generously in a small 2ft x 2ft area.

Carefully apply the sealer with a sponge

3. Per the directions, I made sure to keep the area very wet and evenly coated. To get it even, I used a kitchen sponge and patted the sealer all around that small area. The sponge really helped ensure that I didn’t miss any areas, and it kept any areas from being too heavy, and others too light.

Cover the table with the sealer completely

4. I continued doing this until the entire table was covered with sealer. I had to keep moving my angle to make sure it wasn’t drying. If an area looked dry, I simply sprayed and patted that spot again.

This is how the table looked once the sealer was evenly distributed.

5. The instructions inform you to keep the area fully wet for 15 minutes. So again, if it looks like it’s drying…spray some more sealer on there!

Simple supplies- sealer, rag and sponge. That's all it takes!

6. Once it’s been 15 minutes, I wiped the excess sealer off with an absorbent rag. You’ll want to make sure you get all of the sealer off of the table.

7. Because I’m suuuuper nervous about our table getting stained, I decided to repeat this process twice to make sure it was completely protected! That second coat went on 30 minutes after the first. The bottle says full protections happens after 24 hours, so we avoided using it until then (which was pretty easy since we didn’t even have chairs at this point…)

And the completed project- newly purchased and sealed marble table

And seriously…that’s it! Not very hard, right?! Seems totally worth it to take some time upfront, instead of being stuck with a stain or watermark FOREVER!

I’m not gonna lie though, even though the table is sealed I still find myself always using a coaster. Plus when we eat we use placemats. Am I being overly crazy? Do any other marble owners out there want to ensure me that it is totally safe? No one ever likes to be a crazy coaster lady.

But can you blame me? It’s just sooooo pretty.
