What is a marble sealer?

Marble sealer, also known as a marble impregnator is a waxy substance that’s applied to marble in order to keep from staining or yellowing. It’s an extra barrier of protection for your flooring investment, akin to what polyurethane does for wood floors. Marble sealer consists of a combination of oils and waxes that is designed to penetrate deep into the pores in the stone. It fills the pores with an oily barrier, which is what helps protect your marble from staining. When water hits this shiny surface, it beads up and repels rather than soaking into the stone itself. Therefore, you don’t have to worry about murky residue or discoloration once it dries.

The oil mixes together with fine particles in order to make a glossy coating on top of your marble. This means that you will get a durable finish once it’s applied properly. However, you need to know how long marble sealer takes to dry in order for it be effective at sealing.

Why use a marble sealer?

There are multiple reasons why you should consider using a marble sealer:

1) The sealers will help prevent spills from seeping into the pores of the stone and

2) They keep dirt particles from leaching out onto your flooring surface. Both these problems can eventually lead to chipping if not addressed

3) Sealer will improve the look of your marble  floor by filling in stone pores and level out discoloration

4) In the case of unsealed marble, a sealer can be used to smooth over any scratches.

How to apply marble sealant

Step 1: Prepare the marble: you need to dry the surface of the marble with a towel and remove any grease on it. Then, dampen the sponge with water, wipe it on the surface carefully. Rub your fingers or roller to make sure that there is no dust left behind.

Step 2: Apply plenty of sealant into the sponge then rub it onto your marbles gently until they are shiny and glossed up again. Make sure that you work in even strokes on each section of your stone in order for a smooth finish. The whole process only takes 15 to 30 minutes. You can use cotton swabs or toothpicks to help you apply sealants on every corner of your floors if necessary. After applying the sealer you can let it dry for several hours or overnight. Then, you are ready to put things back in place and enjoy your sparkling marble.

Common mistakes people make when applying marble sealer

When people first use marble sealer to protect their countertops, they often have difficulty getting the results they were hoping for. This is usually because of a few common mistakes that are made along the way. Let’s take a look at these:

Mistake 1 – Improper prep work before applying marble sealer.

Marble Sealer will not be able to bond properly if the surface it is being applied on has not been properly prepared beforehand. In order for sealant or polish to stick to any surface, there has to be something that can actually bond with the product. A dirty and dull countertop is simply not going to provide this necessary base for your marble polisher to adhere too effectively.

Mistake 2 – Improper applying of marble sealer

Another mistake that was made often is applying too thin of a coat. The application must be very even so as not to have areas where the polish will not adequately cover and therefore, areas will appear dull in appearance. Thick coats are also another reason for marble sealer failure because when they dry it leaves behind an oily residue which makes the surface much more prone to scratching and scuffing than if you had used just one very thin and even layer.

Mistake 3 – Using improper polishes or tools while revitalizing marbled counters or other surfaces

There are some specific types of polishes that should only be used on certain types of countertops. For instance: Oil-based products like soap should never be used on painted concrete.

Using a professional service vs doing marble sealing yourself

If you are looking to have your marble sealed properly managed, there are five main factors to consider: Cost, Time Commitment, Pain and Discomfort (As you’ll be doing the job yourself), Skill Level (Are you capable of getting a professional result?) and Personal Preference.

With regards to cost, Professionally sealing marble sealers can cost between 5%-15% more than DIY marble sealing products. If it’s a large-scale project then this could potentially save lots of money in labor costs over the course of many years. However, if you’re only sealing one or two areas then it might not be worth forking out extra cash on professional service – especially as they may charge an additional fee for things like travel time. Professionals will seal your marble more quickly and better than a DIYer, but they will also use more expensive (and often harsher) products.

A professional worker will have all the right tools and products to guarantee the best result, and you should never need more than two or three coats of sealer – so it’s worth paying for quality. However…if you’re just sealing one or two small areas yourself then there’s no need to pay for professional services. You can simply buy some chemicals from your local hardware store as they’ll be cheaper without sacrificing great results. A 3-5% discount on cheap sealers won’t make any real difference in cost vs a professional service over time!

How can you tell if marble is sealed?

The basic rule of thumb is if the finish appears uniform and there are no chips or cracks, it has been sealed. However, in order to be 100% sure, you can do a quick test on the surface to see how likely it is that your marble countertop could get damaged by water. Take a piece of newspaper (make sure no ink from the paper was used on your stone – never use an ink pen on marble!) and pour some water onto the top. If it soaks in quickly without leaving any potential for staining then you know it’s been sealed well!

Does sealing marble change the color?

Marble is comprised of minerals, primarily calcite or dolomite. Both of these minerals are crystalline and will not change their color when sealed.

The common misconception about sealing marble is that it will change its color. While the sealer itself may impart a slight color to the stone, the process should not permanently alter its optical properties.

It’s important to remember that different colors and hues of marble can vary greatly due to multiple factors, one of which being the mineral makeup of that particular slab. Colors such as black or green marble are comprised of dark minerals such as pyrite or malachite and these stones tend to be less porous than lighter colored marbles that typically have calcite crystals in them.

How long does marble sealer last?

Marble sealer lasts for years and years but is not a permanent sealer. It will eventually wear off, especially if exposed to the elements (water), use & traffic (dirt from shoes, etc.), or other harmful substances – like paint strippers containing methylene chloride…

It’s best to re-seal your marble every one or two years for maximum protection. The only thing that will last forever is marble itself. Marble is extremely durable when sealed properly! That said, you can still damage it with improper cleaning techniques.
