Benefits To Sealing Polished Marble

Let’s proceed by taking a look at some of the benefits of sealing your polished marble surface.

1. Sealing Polished Marble Protects From Staining

One of the benefits of sealing polished marble is that it protects against stains. It won’t protect completely, because spills are bound to happen, but this will help in most cases.

Sealing your polished marble surface provides an added layer of protection against stains. This is especially important if you have children or pets in your home.

So if you’re looking for an added protection against stains on your flooring, countertops, or walls, then it may be worth the extra work of maintaining them regularly by sealing.

This is one of the main reasons to consider using a sealant would be the added protection from stains which provide an excellent barrier between spills and your beautiful marble surface – especially when it comes to high traffic areas like kitchens where there may always be cooking oil on the countertop!

2. Sealing Polished Marble Makes It More Easier To Clean

The sealant will also make it easier to clean and keep the polished marble looking nice. As long as you use a high-quality, non-abrasive cleaner on the surface regularly this can be very effective.

Polished marble is beautiful but it does need regular maintenance to preserve its beauty.

3. Prevents Acid Damage

Another reason to seal polished marble is that it can be damaged by acid. Acidic foods, such as tomatoes, lemons, and oranges will cause damage to the surface of polished marble over time.

Acid damage can be very bad and in some cases can be permanent. It’s important to seal polished marble surfaces so that acid is not a problem.

A typical sealant will prevent this from happening and keep the surface looking as good as new for many years!

It is also recommended when cleaning your kitchen countertops not to also use an acidic cleaner, such as vinegar, lemon juice, bleach as they could damage the material over time.

Drawbacks of Sealing Polished Marble

1. Cost

Sealing your polished marble surface will cost you a few bucks which can get expensive really quick. This is because what’s actually involved in your marble sealing is a sealer and then a polish.

These are two products that you will have to buy.

The amount of money spent on sealing the marble also depends on how large your surface is because it’s not just one product being used but two. This means more time for the application process as well (usually about an hour).

2. May Require An Expert

Not everyone knows how to properly seal the marble. If you’re not an expert in this area, then it might be difficult for you to do so and may require hiring a professional.

I have seen a lot of unsuccessful attempts by people who have tried sealing their own polished marble surfaces only to realize that they need help from someone else as soon as possible because of the mistakes made during the application process or even improper technique used.

It’s best if you give yourself time and money to hire somebody who will know exactly what needs to be done when it comes down to cleaning your kitchen countertops while keeping them safe at the same time!

Tips On Sealing Polished Marble

  • There’s a variety of ways you can seal the polished marble. The most popular is using products that can be found at Amozon such as wax, oil, or varnish.
  • These substances will help protect the surface from things like dirt and grease while also providing some level of hardness to counter items that may scratch your flooring over time.
  • It’s important to keep in mind that sealing is not only meant for newly installed surfaces but it should be done on old ones too! This is especially true if you have noticed any wear and tear occurring due to constant use, making the original finish more vulnerable than before.
  • If you want an alternative option for protecting your polished marble then there are several types of paint available at hardware stores etc., including clear varnish, gloss, or satin.
  • This process can be done on a DIY basis but it’s recommended that the surface is cleaned as much as possible first to ensure there are no contaminants like dust or dirt left behind which could cause problems for you down the road such as peeling and chipping paint.
  • The sealant should also allow some degree of shine which will offer protection from those hard surfaces in your home such as tables, chairs, etc., while still allowing good traction so things don’t slide around too easily.
  • If you’re going to use a sealant you’re not familiar with then make sure to test it out on an inconspicuous part of the marble.
  • If you’re going to use a sealant, be sure it’s something that can withstand chemicals.
  • If the marble will come into contact with water or other liquids such as condensation from a humidifier then make sure you find one that won’t react negatively.
  • The goal is for your marble surface to look new again when finished without all of those pesky imperfections!
  • Wipe down the surface with a damp cloth or paper towel.
  • Once you’ve cleaned up all of your messes, apply sealant and watch for an instant shine!
