What Is A Penetrating Concrete Sealer?

A penetrating Concrete Sealer is a group of such a substance which is porous itself but never allows the foreign items to cause damage to the concrete floor.

More specifically, the sealer penetrates the surface creates underlying adhesion which is unlikely to peel, disseminate, or blister. It is widely used on any surface that is susceptible to water, oil, or any liquid substance.

Overall, it is an ultimate emulsify agent that is breathable so moisture will certainly diffuse up to 95% but does not change the color of the surface or any compounds.

What Are the Types of Penetrating Concrete Sealers?

Penetrating concrete sealers are of five types, and they are Silicates, Silanes, Silicones, Siloxanes, and Fluorinated substances. Let’s start defining the first one sodium silicate. It is a densifier that makes barriers on concrete surfaces resulting in a consolidated form.

Except for Silicates the rest of the four compounds also penetrate the surface deeply but work as water repellent compounds. As a result, the surface can absorb very less amount of water. It helps concrete damages caused by water, and you won’t see spalling, cracking, or pitting.

Different weathers, wind erosion, and organic growth of mold or mildew become unforgiving to our concrete surface. The Cryli-Tek for your surface traps polymer inside and exhibits aesthetic high-gloss color. Moreover, it offers the same bait of water penetration like any water-based sealant.

Sadly, but truly the high-gloss appearance on the stamped concrete creates a barrier to detect minor cracking. Things would be more deteriorating for relatively old concrete with some crannies. The semi-gloss EnduraSeal would be a more safe, inexpensive and thus an alternative pick for you.

Pros:

  • For a driveway, concrete treats harmful oil compound Xylene & Toluene
  • Prevents flaking, staining, non-yellowing, and exposing UV light
  • Cure bubbles which make the concrete dull & cloudy
  • Avoid water ingression, also keep the surface non-slippery
  • Protect from dusting, wind eroding and weathering effects

Cons:

  • It seals the surface effectively but is unable to restrict any abrasive product which takes a little maintenance.

How to Choose the Best Penetrating Concrete Sealer?

Depending on your driveway surface, there are a variety of sealers out there. For example, if the surface has a slope, then a slip-resistant sealer would be the right trade-off. On top of that, the wet areas are sealed through the porous elements resulting in a dramatic reduction of water absorption up to 95%.

To cure the faded colors, high gloss concrete sealers come with tint packs which make the surface transparent. Besides, different types of products vary in producing different gloss levels from mid to high range.

If your driveway is more susceptible to dust or stain formation, you need to opt for Sodium/Lithium Silicate concrete sealers. Notably, we get to see the surface often contaminated with leaves, pet urine, grease, sticky oil, and many more. The right bait will kick off all of them by digging inside the pores and creating a strong barrier to let them in.

Needless to say, how to freeze-thaw damage harms the surface in a very short life-span of it. Here the best Water Repellent Sealers not only sink into the pores but also withstand the cold water. As a result, the chances of having a cracking surface reduce to a great extent.

Another aspect of enjoining the tough compound chemicals is to get protection from high temperatures when driveways are exposed under the sun. The surface also creates contact with UV rays, fading the true colors, and shine. In that case, an Acrylic penetrating sealer will be the perfect one.

Aside from the freeze-thaw damage, the driveway may have a cracking surface from excessive moisture resulting in a bloom surface at the end. Besides, salt damage is another phenomenon that leads to the same direction. A special sealer containing Alkali-Silica Reaction (ASR) will save the ass of such a surface. Because such a chemical can raise the reduced pH level and uplift the premature degradation.

How to Apply Concrete Sealer?

Go ahead with the following step by step process to know the application process:

Step 1: Know your sealant first like the dry time, containing what amount of gallon.

Step 2: Start from the thin coating and to smoothen the upper surface.

Step 3: After thin coating, pour a gallon of sealer covering the surface varying from 250 to 500 square feet.

A Tip: The more porous your concrete floor the more intensive sealing will require. The Interior floor should expose enough air and sunlight to let the coating dry faster.

Step 4: After the first coating, you will need to wait for one and half an hour at least based then go for the second one.

A Tip: Check out the manufacturer details to sort out the downtime.

Step 5: You may perform the first coating haphazardly like following either vertical or horizontal method and no matter in what angle or in what direction onwards. But on the second coating, we recommend following the horizontal/upward direction, adjusting the right angle correctly.

Step 6: After coating each line at a 90-degree angle, mark the edge or hairline with chalk or any marker then keep doing until last.

A Tip: This is a technique that saves your sealant not applying it twice on the surface.

Why You Should Use A Concrete Driveway Sealer

Water is the worst enemy of any driveway surface like concrete. Needless to say, the importance of a sealer with the maximum penetration feature.

As a result, it slowly sinks inside and won’t allow a liquid-like substance to diffusion outside. Here is why, your concrete driveway won’t be shaky, soggy but in return, extends the maximum life-expectancy, onwards.

We should use such a sealer that penetrates the concrete floor as deeply as possible and fixes everything that you expect to see.

Keeping this in mind the right sealer is pretty breathable so moisture won’t sit inside the underlying layer of your concrete driveway. Surprisingly a good sealer is low in VOC, spreads fewer fumes, and holds up kinship to the environment.

In a deeper sense, you need an emulsifying agent which secures your concrete driveway surface from potholes, cracks, discoloration, stipping off, dust, mites, debris eventually, enough safe with low-VOC, non-toxic, or non-fumes particles.

Frequently Asked Questions (FAQs)

What does a concrete floor sealer do?

A concrete floor sealer prevents foreign objects (dust, mites, debris, oil, grease, etc.) to weaken the surface from striving and deters water to let inside afterward making the surface soggy and damaged.

Is it better to roll or spray concrete sealer?

It depends on the sealer type which either offers the individual application or both. In a deeper sense, a sealer with a slow-evaporation process is a good fit for rolling, on the contrary, fast-drying sealer allows spraying on the surface.

How long does the concrete sealer last?

It depends on the surface whether it is sealed previously or unsealed and new or old. Traffic exposure is another variant factor as well. Putting all the factors the concrete sealer may last from 2 years to 10 years.

How many coats of sealer can you put on concrete?

A sealer may apply the coat up to two times. Most penetrating concrete sealers usually require two times coating since it is pretty porous to the surface. The one-time coating is commonly seen with the solvent-based sealer with its densifier chemicals.

How long does wet look sealer last?

Wet look sealer doesn’t resist the abrasion and is more susceptible to peel off. So, if it contacts abrasive products closely it may last for 2 months. On-contrary, the sealer turns out durable for up to 5 years.

Do you have to acid wash concrete before sealing?

Yes, if you want to paint the concrete first and then apply the sealer onwards, then acid wash would be an effective and must-do task for you. Besides, the relatively old but unsealed concrete surface needs to go through it.

What happens if it rains on a concrete sealer?

When a concrete surface is sealed thoroughly, the water from rain won’t sleep inside an integral part of it. So, you won’t get to see wet or soggy surfaces even after intermittent rainfalls. The pores of the surface have barriers which are called water beading resistance.

Conclusion

Sealing, waxing, and guarding your concrete surface is a one-time decision for a session. Once you have invested then there is no way to return. Here is why choosing the Best penetrating concrete sealer is a painstaking job indeed.

You need to examine several aspects and get to see which sealer turns out great in what condition. After inspecting many weathering conditions, types of concrete surfaces, applications, and from affordable to expensive prices, we showed them all.
