Does Sealing Flagstone Keep It from Flaking?

It is a diplomatic question, which comes with the dual answer, No and sometimes Yes.

According to users’ reviews and experts’ suggestions Sealing does not keep flagstones from flaking for it traps the moisture in. But before we dig in, let’s beware about flagstone first!

Flagstones are basically flat stones, cut in several shapes for home or outside decor. For instance, it can be square, rectangular, or even unshaped sometimes. And it is generally used as walkways, flooring, ceiling, memorials, headstones, etc.

It is generally a type of Alluvial rock or you can say sandstone blended with quartz and feldspars (Aluminum and Potassium) which bonded with silica, iron oxide, and calcite which give it cementing colors such as buff, blue and Red.

Flagstone flaking is a natural deterioration of sand layers. Well, it is not the only reason; it may be caused by chemicals or water entrapment sometimes. Other times, it occurs for less maintenance, cleaning, and removing of stains.

As of now, the sealer claims to protect it from dust, stain, water, and other things. But it can hardly stop popping out of stones.

Again without sealers, your flagstone will be fruitless already. So, I would better suggest users use hard flagstones rather the soft ones.

And when it is about sealing, take any professional help. They will testify your stone and then suggest you the correct sealer, which will give you long-lasting effect.

If you want to use your money wisely, take advice from experts. As we all between every action and reaction, precaution is the best one to choose.

Though sealers claim to be waterproof and water repellent, for a long duration of time, it goes off to the opposite. Again, in further cases, users use it incorrectly without proper knowledge.

Factors To Consider While Choosing Sealer For Flagstone

Factors To Consider While Choosing Sealer For Flagstone

Divers sorts (Acrylics, Polyurethanes, Epoxies, Penetrating sealers, etc.) of sealers are available in the market. However, you can’t use them all without proper knowledge.

You have to justify it and then satisfy your need. So, you need to consider some obvious factors while sealing Flagstones. To elaborate, they might be,


Due to the long run of stress and weighty pressure, the sealer might get hazardous sometimes. There you need to resupply it to the pores of flagstone.

Again it is also necessary for the flagstones’ natural lifespan. Re-coating gives it a fresh look again with a healthy finish.

Can Endure UV Rays and Sunlight

As the sealer is the top layer, it has to go through sunlight and UV rays. Be sure to use the resisting one, which will not leave any yellowing effect.

It also confirms the longevity of the sealer on the flagstone. Sometimes for sunlight and UV rays, the flagstone gets darkened, and it is not acceptable at all. It makes the flagstone look very ugly.


Reconsider the flagstone’s natural look issues while protecting your decorative flagstone. It is better to choose a breathable sealer.

Because most of the time for this quality, air, vapor, and moisture get entrapped and causes deterioration, reviews say it is safe to use penetrating sealers for the best feedback.


The sealer must fit well with the flagstone in the context of compatibility. As the sealer is the sacrificing layer, it must endure the daily misuse with protection and without much maintenance.

It will also reduce the chances of flaking, cracking and popping out, etc. Compatibility is what decides the lifetime of both the flagstone and the sealer.

Stain & Water Resistant

If the sealer doesn’t provide these two benefits, it’s useless to even seal your flagstone. The sealing surface must go through the dirt, filths, and sticky stains.

According to experts, it is better and safe to use lower-level VOCs (Volatile Organic Compounds) and water-based sealers than solvent-based. Solvent-based sealers are biodegradable.


Users always seek fewer maintenance sealers, for it is money-saving and less laborious features. Therefore, you must consider it before sealing your flagstone.

Again, it also saves the flagstones’ natural look. Over maintenance can cause overpressure, which may harm the look sometimes.

Is Not Slippery

It is totally unsafe to use a slippery surface for flagstone as a sealer. It can cause many types of accidents. So, you should avoid it unless this sealer is being used for roofing.


Matte-finished sealers are more reliable than glossy ones. A glossy sealer can entrap moisture and water into the pores if there’s heavy rain or snowfall.

So, the matte-finished sealers keep the underlying flagstones natural and less composed.

Cleaning Process

Use a more cozy sealer, easy to clean dirt and grimes. This will make you less tired after work. We all have to maintain hygiene, and so cleaning is also a major part of sealing. Daily cleaning can cause the sealer less maintenance.

Applying Process

Easy to applications are easy to peel off after years. Most of the user almost destroys their flagstones while peeling off, for hard applying process.

Moreover, hard applying processes sometimes cause failure due to a lack of the right information too. So overall, it will be a smarter decision to choose the easy-going processes.

How Do You Apply Flagstone Sealer?

How Do You Apply Flagstone Sealer?

Without sealing, the flagstones cause water impregnation, discoloration, cracking, chipping, etc. Again, mold, mildews, grimes, stains, extra exposing UV rays, sunlight, calcium deposition, etc., works like a threat for it.

It does not need any elaboration that to keep flagstones’ natural look and lifespan. You need to seal it for a must. Through proper cleaning and maintenance can also be fruitful. It’s safe to take prior cautious.

There are some simple processes to apply sealer on flagstones. They are given below.

Step 1

Before using any sealer, clean your flagstone surface first. For that, you will need a broom (soft-bristled) or mopper, dust-keeper pan, brush or a vacuum cleaner, or a power washer and detergents or soap water.

Step 2

Use a broom and dustpan for dry filths to carry out of the flagstone and mopper for liquid stains. You can also use detergents and soap water for stubborn oily stains.

Some may use a vacuum cleaner or pressure washer to clean the surface layer or brush on obstinate grimes.

Step 3

The next part is to cover the joints of flagstone with sands. You can use any type of sand and yard broom to fill up sand equally to the joints. But keep the level a little bit low, as sealing with rollers will fill them to the top with excessive sands.

Step 4

After the previous process is completely done, go for the coating process. With plenty of sealing products comes plenty of ways to seal the flagstones.

For this, you may need a paintbrush or roller or an industrial sprayer. And follow the instructions of the product bottle. We have already discussed it earlier.

Step 5

Finally, apply the next level of coat to ensure full protection. But don’t use a brush; it may destroy the first level of coating.

Make sure it’s a holiday and your family is out of home, so nobody can halt the process. Again, it is needed for better sealing.

Over mess and crowd will allow less scope and give facility to dry or get destroyed the sealing surface, for it needs time for both cleaning and drying process.
