Picture
If you have countertops in your kitchen that are made of great-looking marble, then you may be wondering how to seal marble countertops? It’s only natural that you would want to keep your marble countertops looking good for as long as possible. The short answer to that question is yes, you can seal marble countertops but it’s not just as simple as having the desire to do so.

So, what do you need to do as far as sealing your beautiful marble countertops are concerned? Here are the steps involved in that process. 

Step 1: Prep Work

As with any type of paint or sealing job, a big part of how to seal marble countertops is the prep work that goes into the job. This can be done with just a damp cloth or by using a special marble cleaner. You just need to make sure there is no dust or any other surface contaminants on the marble countertops before you start to seal them. Allow the countertops to dry for 30 minutes to an hour after doing this.

Step 2: Apply the Special Sealant

You can’t just apply any sealant to marble countertops. It must be a sealer specifically made for this task. Most of which come in spray form. Spray a generous amount on the countertop being sure to coat it 100%. Work in sections to ensure that you don’t miss any areas and there is no need to wipe or brush it in. 

Step 3: Watch How the Sealer Dries

Once you have applied the marble sealer, it’s very important to check on the sealer every few minutes to see how it’s drying. This is the phase of the project that many overlook but it’s important. You have to observe the first 30 minutes of drying to make sure that the sealer fills the pores and not just dries on the surface. If too much sealer goes into the pores you will also have to coat the surface again. Lightly wipe off any excess sealer on the surface to avoid hazing. 

Step 4: Allow the Proper Amount of Time for the Counter to Dry

The last step in learning how to seal marble countertops is allowing them to dry properly. Although your newly sealed countertops may appear to be dry after the sealant has been on for a few hours, this is not the case. So don’t be too tempted to start using your marble countertops too soon. If you want your sealant to cure completely, you should wait for at least 24-hours before using your marble countertops again.
