When Should You Use Marble Sealer

Untreated Stain

Marble accessories, extensions, and surfaces are porous. It’s especially true if you are using natural marble without any polish or honing. Thus, it’s quite easy for stains, such as a coffee or a wine spill to seep through those pores.

If you don’t immediately wipe off the stain, the liquid will keep travelling deeper into the internal structure of the marble by using the pores. This will make the stain permanent and very hard to remove.

So, before something like this happens, you should use a marble sealer.

It will use a carrier agent to send resins into the marble, which later becomes solidified to close up the pores for good. Thus, even if you accidentally spill something on your marble kitchen top or dining table, the stain won’t be able to penetrate through so easily.

Natural Marble

If you are using purely natural marble, then applying a sealer is a must.

Natural marble is adored by many due to its unaltered color and texture, which can add a luxurious organic feel to any décor. However, among all the types, natural marbles have the most porous surface. Therefore, they are most vulnerable in terms of permanent staining, which is every marble lover’s nightmare.

But, if you use a marble sealer at the time of installation and then reapply them within an appropriate time window, your marbles will be much safer from gaining a permanent stain on their gracious natural texture.

First Time Installation

Due to being newly installed, the marbles are already in a fragile situation. Thus, an accidental leak or a flow of dust (in terms of an outdoor installation) can seriously damage the texture of your marble.

So, when you add in the inherent porous nature of marble, this is literally the worst time you want a red wine spill on your newly installed kitchen top.

This is why you should use marble sealers at the installation stage.

Heavily Used Areas

You should always apply marble sealers at heavily used areas. This may include bathroom floors, kitchen extensions, sink extensions, etc. If we are talking outdoor use, consider surfaces like fountain guards, garden sits, pathways, patios, and backyards.

These areas take a strong beating due to a ton of usage (in indoor situations) and foot traffic (in outdoor situations). So, it’s normal for a lot of spillages, dust, and moisture to take place on them. As a result, you’ll be faced with lots of hard to remove stains that have already sunk in.

Unless you secure these surfaces with a high quality marble sealer, it’s very likely that the marbles will stain, fade, and even show crack signs over time.

Top 10 Best Marble Sealers – Reviews in 2022

1. TriNova, Marble Sealer, Protector & Care Product

TriNova, Marble Sealer, Protector & Care Product

The SYNCHKG079542 is an elegant combination of sealer and protectant that provides you sustained maintenance for all types of marbles.

It’s contained in a stylish white sprayer, holding 540-milliliters of liquid. The sprayer has a ridged cap for spontaneous usage. It’s designed with an easy-push trigger, lessening finger stress while a square nozzle covers more surface with less effort.

The product is perfect for treating roughly used marbled surfaces. For example, the sink extension, kitchen countertops, and floors of the living room, hallway, front yard, etc.

The AASP (Advanced-Action Stain Protection) tech uses a specialized resin (known as polymers) and carries them into the pores of your natural marble. Once the polymers are integrally solidified, your marble becomes shielded from the inside. This lets them fight off intruding liquids such as a coffee or lemon-juice spill from entering and damaging the insides of your marble.

The “spray-and-wipe” method allows a comfortable yet effective user experience. You simply spray the mixture and then rub off (preferably, with a soft linen cloth) the extra liquid. And, just like that, your marbles now have an extra protective layer on top.

The multifunctional sealer also provides protection against water-spots, streaks, and hazy/gloomy areas appearing on the surface. The mixture is reviewed to perform exceptionally well on treating grouts and enhances clarity of your marble without disrupting a natural look.

Highlighted Features:

  • “Advanced-Action Stain Protection” offers foolproof internal protection.
  • “Spray-and-wipe” method lets you use the product easily yet effectively.
  • It provides protection against water-spots and streaks.

What to Look for Before Buying Marble Sealer?


We recommend purchasing a marble sealer that has multi-functional properties. That is, apart from sealing, the product should also be able to provide a protective finish as an additional layer of protection.

You can also look for sealers that are able to clean and provide a shine to your marble. This way, you get multiple benefits from using a single product.

Fast Reapplication Window And Cure Time

You should purchase a marble sealer that provides a quick intermediary time between multiple coatings and cures fast. This will significantly improve the speed of your workflow. It’ll also allow you to correct errors in coating (e.g. an uneven coat) with ease.

Strength Of Penetration

This feature is one of the most important ones to look for.

You need to purchase a sealer that is formulated with deep penetration technology. This way the sealer will be able to reach the deep seated pores in the marble and lock them. As a result, you’ll get a foolproof stain protection at the deepest level.

Surface Coverage

Before making a purchase calculate the amount of surface you need to cover and then buy accordingly. This will save you from making multiple trips to the utility store or making several orders online to accomplish a single sealing job.

For example, if you need to cover an area of 4000-square feet, 3.785-liters of Miracle Sealant’s 511GAL4 will do the job perfectly. So, match your surface coverage with the required amount of sealant to make a single, perfect purchase.

Specialized Sealing

If you have any specialized sealing requirements, it’s wise to determine that exactly before making a purchase.

For example, some sealers work better for outdoor marble surfaces like patios and some are specifically engineered to seal marbles used around indoor food processing areas like kitchen tops and dining tables.

Also, there are specific sealants to treat natural marbles and other products that are manufactured for polished or honed marble. Some sealers work well on grouts and some don’t.

Thus, determining your priorities in this area will save you from making a regrettable purchase and lead right to the best marble sealer for your marbles.

Dynamic Protection

Look for these protective qualities while purchasing a marble sealer-

  • Water-repellence
  • Deep penetration (e.g. ioSeal by supreme surface)
  • Weatherproofing features for outdoor marble surfaces
  • Protective qualities that can remove old/sunk in stains
  • A protective finish on top after the sealing is done
  • Steak-free usage
  • Residue-removal technology
  • An engineered “quick vapor release” that prevents moisture buildup

Environment Friendliness

You should ensure that the marble sealer you’re purchasing is environment friendly, specifically if it’s being used around a food processing area.

We recommend looking for a sealer that is produced without usage of harmful chemical elements like ammonia, alcohol, etc. Also, ensure that the sealer is biodegradable, doesn’t release any nasty odor, and engineered not to emit health hazardous chemical emissions.

Frequently Asked Questions

How Do Marble Sealers Work?

Answer: Sealers use a carrier, using various penetration techniques, to transport specialized polymers (usually resin) into the deep pores of the marble. The resins then harden to block these pores, making it difficult for stains to sink into the marble.

Do Sealers Provide A 100-percent Protection Against Stains?

Answer: No.

They definitely provide a substantial amount of protection, making it less likely for stains, dusts, and debris to sink into the marble and become permanent.

However, it’s recommended to clean your marbles (preferably with a pH-neutral cleaner) on a regular basis and immediately wipe off stains when they do occur. This will give you an edge at protecting your beloved marble accessories and surfaces.

Why Do I Need Different Types Of Sealers For Differed Types of Needs And Marbles?

Answer: There are a variety of sealers in the market and for good reason. Each of them specializes in certain areas.

For example, a sealer may be perfect to protect your marble walkway but can turn out to be an imperfect choice to use around food processing areas due to its formulation.

On the other hand, an ammonia and alcohol free biodegradable sealer is a proper choice to use on marble kitchen tops but won’t function well on a patio due to lack of weatherproofing features.

Also, sealers for natural marbles and polished/honed marbles are manufactured differently. Thus, it’s important to first detect the purpose of your usage and then make a purchase. Otherwise, applying a sealer may do more harm than good.

What Is A “Streak-free” Feature Equipped Sealer?

Answer: This means the sealer multi-functions as a cleaner and doesn’t leave streak marks after the cleaning is done.

What Is A “Residue-Removal” Property Installed Sealer?

Answer: It means using the sealer won’t leave any waxy or oily residue on your marble after application.

How Often Do I Need To Seal My Marbles?

Answer: It depends on the type of your marble and where it’s located.

Generally speaking, outdoor marble surfaces require more sealing than indoor ones.

However, if the indoor surface is heavily used, such as a bath floor or a cutting counter in the kitchen, then they’ll require resealing every two to three months according to most experts for keeping your marble in the best possible shape.

Final Words

We protect what we love. The same is true for your marble accessories, surfaces, and extensions.

That is why, in this guide, we’ve taken a no-comprise approach to introduce you with the best marble sealers that are equipped on all facets to protect your marble and increase its longevity.
