If you wonder why some garage floors look so pristine and nice, here’s the secret – garage floor sealers. What are garage floor sealers, and how do they protect your garage floor?
Garage floor sealers protect the garage floor from water, freeze-thaw, dirt, oil, chemicals, mould, UV, road salt, and wearing & tearing. You apply garage floor sealers by clearing the floor, applying sealers, and allowing it to cure.
In this article, learn all you need to know about garage floor sealers – pros and cons, types, and how to apply them yourself.
What Are Garage Floor Sealers?
Garage floor sealers are products you use to protect your garage floor. They work like a shield, keeping it safe from things like water, oil, dirt, or chemicals that can make it look bad or wear out over time.
If you want your garage floor to last longer and look better, a sealer is a great idea.
When you apply a floor sealer, it creates a protective layer on the surface. This layer can help prevent stains from things like:
- oil spills,
- grease, or
- paint.
It also stops moisture from soaking into the concrete, which can cause cracks or damage, especially if you live in a place where it freezes in the winter.
There are a few types of garage floor sealers, and choosing the right one depends on what you need. For example:
- Acrylic Sealers: These are simple and affordable. They provide a clear, protective layer but may need to be reapplied more often.
- Epoxy Sealers: These are tougher and more durable. They give your floor a shiny, professional look and are great for handling heavy use.
- Penetrating Sealers: These soak into the concrete instead of sitting on top. They’re good for protecting the floor without changing how it looks.
Why Should You Seal Your Garage Floor?
A garage floor sealer is more than just a cosmetic upgrade. It’s a practical investment that helps keep your concrete garage floor protected and looking great. Here’s why you need one.
Protects Against Oil Stains and Moisture
Ever tried scrubbing out an oil stain that seems to have become one with your floor? A sealer acts like a barrier, stopping oil, moisture, and other contaminants from seeping into the porous surface of the concrete.
Products like Ghostshield 8510 penetrate deep into the pores, offering hands-down the best protection against intrusion and stains.
Adds Durability to the Surface
A concrete garage floor takes a beating—car tyres, heavy tools, welding slag, and more. Adding a floor coating like epoxy or polyurea gives it a durable layer that withstands wear and tear.
Epoxy floors not only last for years but also create a smooth, glossy finish that looks incredible. If you’re worried about slipperiness, go for an additive that provides texture.
Improves Appearance
A sealed floor isn’t just practical; it’s decorative. A clear coat enhances the natural look of the concrete, while tinted coatings let you customize the finish.
Whether you prefer a glossy epoxy floor or a natural look with penetrating sealers, the result is a polished, professional appearance that transforms your space.
Prevents Cracks and Deterioration
Water intrusion is the silent destroyer of concrete floors. It seeps into pores, freezes, and expands, causing cracks over time.
Garage floor sealers, especially densifiers, fill the pores of the concrete and block moisture. This makes your floor resistant to damage and keeps it strong for years.
Easy DIY Application
Sealing a garage floor is a weekend DIY project that saves money and gives you full control. Most concrete coatings are easy to apply with a roller or brush.
A gallon of this stuff can provide the coverage and sealing you need for your garage floor, without breaking the bank.
Pros Of Garage Floor Sealer
A garage floor sealer is more than just a nice-to-have. It’s a must for protecting and improving your garage floor. Here’s why you should consider it.
Shields Your Floor from Oil and Stains
Oil stains on a concrete garage floor are like an unwelcome guest that just won’t leave. A sealer creates a barrier that stops oil and other contaminants from penetrating the porous surface.
They penetrate deep into the concrete, offering unmatched protection against stains and moisture. Whether you’re working on cars or just parking them, a sealed floor stays clean.
Makes Your Floor Durable and Long-Lasting
Garage floors endure constant abuse. From welding slag in workshops to the weight of vehicles, they need protection.
A garage floor coating like epoxy or polyurea adds a durable layer that resists wear, chemicals, and impacts.
Polyurea, for example, is tough enough to handle extreme temperatures without cracking. Unlike acrylic, which needs frequent touch-ups, polyurea and epoxy floors can last for years.
Improves the Look of Your Garage
A sealed floor instantly enhances the appearance of the concrete. Whether you choose a clear coat to highlight the natural look or go for a glossy epoxy floor, the transformation is undeniable.
Epoxy coatings are also available in a wide range of colours, so you can customize your garage’s aesthetic. Decorative chips or additives can even give your floor a high-end, showroom feel.
Keeps Moisture Out
Moisture is one of the worst enemies of a concrete slab. It seeps into the pores, freezes in winter, and expands, causing cracks.
A good floor sealer fills the pores and seals the surface of the concrete. This blocks water intrusion and helps keep your floor strong and crack-free.
It’s a must if your garage floor concrete is power-troweled or exposed to the elements.
DIY-Friendly and Cost-Effective
Installing a garage floor sealer is easy to do yourself. Most sealers come with clear instructions, and you can apply them with a roller or brush.
Epoxy kits, for instance, offer enough coverage to seal a standard garage with one pail. Products like Ghostshield 8510 are ready to use, and a gallon can go a long way.
With prices ranging from $51.99 to $109.99, sealing your floor is an affordable way to protect your investment.
Cons Of Garage Floor Sealer
While a garage floor sealer has plenty of benefits, there are some downsides you should consider. Knowing these can save you from surprises later.
The Prep Work is Time-Consuming
Sealing your concrete garage floor isn’t as simple as slapping on a coat of paint. Prep is a must. You’ll need to clean the surface thoroughly, etch it, and sometimes repair cracks beforehand.
If the floor isn’t properly prepped, the sealer might not adhere well, leading to peeling or bubbles. This step can be tedious and might turn a weekend project into something much longer.
Epoxy Floors Can Be Slippery When Wet
Epoxy coatings are glossy and look great, but they can get dangerously slippery, especially in wet conditions.
If your garage is exposed to water or moisture, this can become a hazard. Adding a texture additive helps, but it’s an extra step and cost.
Unlike penetrating sealers, which don’t alter the surface, glossy coatings can be more of a safety concern.
Sealers Can Be Pricey
High-quality sealers like Ghostshield 8510 or polyurea coatings don’t come cheap. A gallon of a premium product can cost $76.99 or more, depending on the type.
For larger garages or workshops, the coverage required can quickly add up. If you’re looking to reapply every few years, the cost can become a long-term investment.
Application Can Be Tricky
While many sealers are marketed as DIY-friendly, applying them properly isn’t always easy.
Epoxy floor coatings, for example, have a short pot life, meaning you need to work fast once mixed. Uneven application can leave streaks, bubbles, or patches that don’t cure correctly.
Even “easy-to-install” penetrating sealers like Ghostshield require even coverage, or you risk leaving parts of your concrete slab exposed.
They Don’t Fix All Issues
A sealer isn’t a cure-all for a worn or damaged garage floor. If your concrete surface already has deep cracks, stains, or pitting, a sealer won’t restore it.
You might need to invest in repairs or resurfacing first. Penetrating sealers, while excellent at protecting from moisture intrusion, won’t change the appearance of your concrete.
If aesthetics are a priority, you’ll need to combine them with a decorative topcoat.
Sealing a garage floor has plenty of pros, but you need to weigh these cons too. From prep work to cost, it’s not always a quick or cheap solution.
Types Of Garage Floor Sealers
Not all garage floor sealers are created equal. Each type has unique benefits and drawbacks, so knowing what you’re getting into can save time, money, and frustration.
Penetrating Sealers: Invisible Protection
Penetrating sealers soak into the concrete surface, creating a barrier from within. They don’t alter the appearance of the concrete, which is perfect if you want a natural look.
Products like Ghostshield 8510 are hands down the best for moisture resistance, making them ideal for areas prone to dampness.
The upside is their durability. These sealers last for years and are resistant to moisture intrusion, oil, and contaminants. They help keep your concrete garage floor looking clean without much maintenance.
The downside? They don’t provide a decorative finish or protect against surface wear. If your concrete slab is exposed to heavy traffic, penetrating sealers alone may not be enough.
Epoxy Floor Coatings: Durable and Decorative
Epoxy is a popular choice for its durability and aesthetic appeal. It creates a thick, glossy finish that transforms a concrete garage floor into a sleek, showroom-like space.
Epoxy floor coatings resist oil, chemicals, and stains, making them a go-to for workshops and garages.
The upside? They’re tough and look incredible. With proper prep and installation, an epoxy floor can last for years. The downside? They can be slippery when wet, especially without an additive for texture.
Epoxy also requires meticulous prep, including cleaning, etching, and ensuring the substrate is completely dry. The short pot life during application also means you have to work quickly.
Polyurea Coatings: Flexible and Long-Lasting
Polyurea coatings are like the stronger sibling of epoxy. They’re resistant to cracks, UV rays, and extreme temperature changes, making them a durable option for outdoor or high-traffic garages.
These coatings are also more flexible, reducing the risk of peeling.
The upside is their longevity. Polyurea coatings dry quickly—often within 12 hours—and are resistant to yellowing over time.
The downside is the price. High-quality polyurea sealers can cost $109.99 or more per pail, making them less budget-friendly for large areas.
Acrylic Sealers: Affordable and Easy
Acrylic sealers are one of the most affordable and DIY-friendly options. They form a thin, clear coat on the concrete surface, offering basic protection against stains and moisture.
They’re easy to install with a roller and dry quickly.
The upside is the cost. At $51.99 or less per gallon, acrylic sealers are a budget-friendly way to seal your floor.
The downside is their durability. These sealers need to be reapplied frequently, especially in high-traffic areas. They also don’t penetrate the pores of the concrete, so moisture and stains can still seep through over time.
Concrete Densifiers: Strength from Within
Concrete densifiers are designed to make the surface of the concrete harder and more resistant to dust and wear.
They penetrate deeply into the pores, reacting with the concrete to fill gaps and increase density.
The upside? They’re great for sealing power-troweled surfaces and preventing dusting. Products like Ghostshield densifiers are resistant to wear and improve the durability of your concrete slab.
The downside is they don’t provide a glossy or decorative finish. If you’re looking for aesthetics, densifiers might not be enough.
Penetrating Concrete Sealers vs. Topical Sealers
Choosing between penetrating sealers and topical sealers for your concrete garage floor can feel like choosing between function and form. Each has its perks and pitfalls.
Penetrating Sealers: Invisible Guardians
Penetrating sealers work by soaking into the concrete surface, filling the tiny pores to create a protective barrier.
They’re perfect if you want to keep the natural appearance of the concrete while guarding it against moisture and contaminants.
Penetrating sealers excel in durability. Once applied, they last for years with little maintenance. You don’t have to worry about reapplying or touch-ups.
These sealers are especially effective for power-troweled surfaces and areas prone to water intrusion. They help keep moisture out, reducing the risk of cracks caused by freezing and thawing.
If you’re budget-conscious, penetrating sealers like Ghostshield 8510 offer great value. A gallon priced at $76.99 or so can cover a wide range of surfaces.
The downside? They won’t protect against surface wear or create a decorative finish. If you want a glossy or decorative look, penetrating sealers won’t deliver.
Topical Sealers: The Showstoppers
Topical sealers, including epoxy and acrylic coatings, sit on top of the concrete like a shield. They not only protect the surface but also transform the appearance of the concrete.
Epoxy floors, for instance, create a thick, glossy coating that’s both durable and decorative. These coatings are also resistant to oil and chemical stains, making them ideal for workshops.
The pros are clear: topical sealers offer durability, aesthetics, and versatility.
But there are downsides too. They can be slippery when wet unless you add a texture additive.
Installation requires meticulous prep, including cleaning, etching, and ensuring the floor is completely dry. A poorly prepped surface can lead to peeling or bubbling.
They also might need more care. Acrylic coatings, for instance, often require reapplication every couple of years, especially in high-traffic areas. Epoxy coatings last longer but may show wear in spots with heavy use.
High-end epoxy or polyurea coatings can also cost significantly more. While they provide added benefits, the price might be steep for larger areas.
How To Choose The Right Garage Floor Sealer?
Picking the right garage floor sealer isn’t a one-size-fits-all decision. You need to consider your floor’s specific needs, your budget, and the long-term benefits. Here’s how to make the right choice.
Floor Usage
Think about how you use your garage. Is it a workshop with heavy tools and welding slag, or just a parking spot?
If your floor faces constant wear and tear, an epoxy floor coating or polyurea might be the best option. Both are durable and resistant to impact.
For light use, a penetrating sealer like Ghostshield 8510 is perfect for moisture protection without overkill.
Surface Condition
Inspect the surface of your concrete garage floor. If it’s power-troweled, smooth, and dust-free, a penetrating sealer works great.
These sealers penetrate the pores and create a barrier from within.
If the concrete slab has cracks or surface damage, a thicker coating like epoxy can help fill imperfections while sealing the floor.
Protection Needs
Do you need to protect against oil spills, moisture, or both? For moisture-prone areas, penetrating sealers are hands down the best.
Densifiers fill the porosity of the concrete to block water intrusion. If oil stains and chemical spills are a concern, a topical coating like epoxy or polyurea offers better surface protection.
Aesthetics
Consider the appearance you want for your floor. If you’re after a decorative finish, epoxy floor coatings are hard to beat.
They’re available in a wide range of colours and can include additives for texture or decorative chips for a showroom feel.
Penetrating sealers, unlike topical sealers, don’t alter the look of the concrete. They’re ideal if you prefer a natural appearance.
Budget
Your budget will play a big role in your decision. Penetrating sealers like Ghostshield 8510 offer excellent protection starting at around $76.99 per gallon.
High-end options like polyurea coatings can cost over $109.99 per pail but offer unmatched durability.
Acrylic coatings are more affordable, often priced at $51.99 or less, but may need frequent reapplication.
Ease of Installation
Decide whether you want a DIY-friendly solution or if you’re willing to hire a professional. Acrylic sealers and penetrating sealers are typically easy to apply with a roller or sprayer.
Epoxy coatings require more prep, including cleaning, etching, and mixing within a limited pot life. If you’re not confident with the process, you might prefer a simpler option.
Longevity
Think about how often you’re willing to reseal your floor. Penetrating sealers last for years with little maintenance.
Topical sealers like acrylic may need reapplication every couple of years, especially in high-traffic areas.
Epoxy and polyurea coatings are more durable, but once they show wear, repairs can be more involved.
Choosing the right garage floor sealer depends on balancing these factors. Whether you want durability, aesthetics, or low maintenance, there’s a sealer to match your needs.
Which Is Better: Water or Solvent Based Concrete Sealer?
When it comes to choosing between water-based and solvent-based concrete sealers, the decision depends on your needs, environment, and priorities. Both types have clear strengths and trade-offs.
Water-Based Concrete Sealers: Eco-Friendly and Subtle
Water-based sealers are the eco-conscious choice. They emit fewer fumes, making them a safer option for indoor use, like sealing a concrete garage floor or workshop.
These sealers penetrate well into the concrete surface and often enhance its natural appearance with a soft, matte finish.
If you want to maintain the natural appearance of the concrete, water-based sealers are the better choice. They create a clear coat that enhances the concrete’s look without changing its texture.
The upside is the ease of application. Water-based sealers are easy to install, even for DIYers, and clean-up requires just soap and water.
The downside? Water-based sealers don’t always achieve the same level of gloss or durability as solvent-based options. If you’re looking for a thicker, glossy floor coating, water-based may not deliver.
Solvent-Based Concrete Sealers: Glossy and Durable
Solvent-based sealers are prized for their durability and high-gloss finish. They’re a popular choice for creating a decorative epoxy floor or a garage floor coating with a professional, showroom look.
These sealers bond tightly to the substrate and can resist stains, oil spills, and moisture better than most water-based options.
Solvent-based options, like polyurea coatings, are more resistant to extreme temperatures and weather conditions. They’re less likely to peel or yellow under UV exposure.
Solvent-based sealers are more durable, making them ideal for high-traffic concrete garage floors. The glossy finish not only looks decorative but also helps keep surfaces easy to clean.
The downside is their strong odour during application. You’ll need proper ventilation, and permission to access the area might be denied until the fumes dissipate. Cleaning up requires solvents, which can add to the overall cost.
How Much Does It Cost to Seal a Concrete Floor?
Sealing a concrete floor can cost as little as $51.99 for basic acrylic sealers or go beyond $109.99 for premium polyurea coatings. The price depends on the type of garage floor sealer you choose and the size of your floor.
For a standard two-car garage, a gallon of Ghostshield 8510, one of the hands-down best penetrating sealers, provides excellent moisture resistance for around $76.99.
If you need a thicker floor coating like epoxy, expect to pay $82.99 to $109.99 per pail. Epoxy floors require more prep and multiple coats, which can increase the cost further.
DIY projects save you money. A roller and proper prep can help keep costs low, but remember, the surface of the concrete must be clean and etched. Professional installation, while convenient, adds significant labour charges.
Coverage also affects costs. Most sealers cover between 200 and 400 square feet per gallon, depending on the porosity of the concrete.
For highly porous floors, you may need more product. Durable options like polyurea last longer but come at a premium.
How To Seal Garage Floor?
Sealing your garage floor might seem intimidating, but it’s surprisingly straightforward with the right tools and prep. Here’s how to do it, step by step.
Clear and Clean the Floor
Start by clearing everything off the garage floor. Remove all cars, tools, and storage items. Sweep thoroughly to get rid of dirt and debris.
If your concrete garage floor has oil stains, use a degreaser to clean them. For stubborn stains, scrubbing with a stiff-bristled brush can help lift the oil.
Rinse the floor well and let it dry completely. A wet floor will prevent the sealer from adhering properly.
If you’re using penetrating sealers, the floor must be completely dry for it to penetrate the pores of the concrete effectively.
Repair Cracks and Damage
Inspect the surface of the concrete for cracks, chips, or pits. Use a concrete repair compound to fill any visible damage.
Let the repairs cure before moving to the next step. This ensures the garage floor sealer applies evenly.
For a power-troweled or polished surface, you might need to scuff the concrete slightly to improve adhesion. A light sanding can help create a better surface for the sealer.
Etch the Concrete (If Necessary)
Etching prepares the surface by opening up the pores of the concrete, allowing the sealer to penetrate more deeply.
Many DIY etching solutions are available, often containing muriatic acid. Follow the manufacturer’s instructions and wear protective gear.
Pour the etching solution onto the floor, scrubbing it with a stiff broom to ensure even coverage. Rinse the floor thoroughly to remove all residue. Let it dry completely before proceeding.
Choose the Right Sealer
Pick a sealer that fits your needs. For moisture resistance, penetrating sealers like Ghostshield 8510 are hands down the best.
If you’re aiming for a decorative, glossy finish, go for an epoxy floor coating or polyurea.
Remember that topical sealers like epoxy are also resistant to oil stains and chemical spills, making them great for workshops.
Calculate how much sealer you’ll need based on the coverage listed on the product. A gallon of Ghostshield 8510 typically covers 200-400 square feet, depending on the porosity of the concrete.
Apply the Sealer
Use a roller or sprayer for even application. Start at one corner and work your way across the garage floor in sections.
If you’re using a penetrating sealer, apply a thin, even coat and let it soak into the concrete. For an epoxy or polyurea coating, mix the product according to the instructions and work quickly due to its short pot life.
Apply the first coat evenly and let it dry. If a second coat is needed, wait the recommended time (usually 12-24 hours) before applying. Avoid walking on the surface while it cures.
Watch for Uneven Areas
Check for areas where the sealer beads on the surface or hasn’t absorbed evenly. These spots might require additional product or reapplication.
A roller can help smooth out inconsistencies in thicker coatings.
For an epoxy floor, add decorative chips or texture additives during the first coat if desired. This not only improves aesthetics but also helps reduce the floor being slippery when wet.
Let It Cure
Curing times vary depending on the type of sealer. Penetrating sealers often dry within a few hours but need a full 24 hours to cure completely.
Epoxy and polyurea coatings may take longer, especially for heavy foot or vehicle traffic.
Make sure the area is well-ventilated during this time. Avoid allowing dust or debris to settle on the wet floor coating, as it can ruin the finish.
Maintain the Sealed Floor
Once the garage floor sealer is fully cured, maintenance is straightforward. Regular sweeping and occasional mopping help keep the floor looking fresh.
For epoxy floors, avoid using harsh chemicals that can dull the glossy finish.
With the right prep, product, and patience, you’ll have a sealed garage floor that looks great and lasts for years.
Garage Floor Sealer Improves Your Garage
Sealing your concrete garage floor is a simple yet effective way to protect it from wear, stains, and moisture.
With the right garage floor sealer, proper prep, and a step-by-step approach, you can enhance your floor’s durability and appearance.
Whether you choose penetrating sealers for deep protection or epoxy coatings for a decorative finish, sealing your floor ensures it lasts longer and stays easy to maintain.
A sealed garage floor isn’t just practical—it’s an investment in your space.
FAQ
Should You Seal Old Concrete Floors?
Sealing old concrete floors is a smart way to revive and protect them. Over time, moisture, oil, and stains can damage the porous surface of the concrete.
If the floor has cracks or pits, repair them before sealing. For heavily worn surfaces, a thicker garage floor coating, like epoxy or polyurea, provides added durability and a fresh, glossy finish.
Prep is crucial. Clean thoroughly, etch the floor if needed, and ensure it’s dry. A concrete sealer applied properly can transform an old, tired floor into a durable and attractive surface.
Can You Pressure Wash Sealed Concrete Floors?
Yes, you can pressure wash sealed concrete floors, but be cautious. A high-quality garage floor sealer is resistant to moisture and can handle light-pressure washing.
Avoid using excessive pressure that could damage the floor coating or penetrate the sealant barrier. Stick to settings below 2,000 PSI and use a wide spray nozzle to distribute water evenly across the surface of the concrete.
If your floor has a glossy epoxy floor coating, pressure washing can help keep it clean without scrubbing. Be mindful of slippery areas once wet and avoid harsh detergents that could dull the finish.
For penetrating sealers or densifiers, ensure the water doesn’t pool for too long, as it may seep through porous areas not fully sealed.
Pressure washing is an effective way to maintain the appearance and durability of your sealed concrete garage floor when done correctly.
Will Sealing Make Garage Floors Slippery?
Sealing your garage floor can make it slippery, depending on the type of sealer you use. Glossy floor coatings like epoxy or polyurea are often slippery when wet.
Adding a texture additive during installation helps reduce this risk. These additives create a non-slip surface, making it safer for workshops or garages exposed to moisture.
Penetrating sealers don’t alter the surface texture, so they’re less likely to create a slippery surface. They penetrate the pores without leaving a glossy finish.
If safety is a concern, avoid smooth, high-shine coatings unless you include anti-slip additives. Regular maintenance, like keeping the floor free from water and oil, also helps prevent accidents.
Can You Add Sand To Garage Floor Seal?
Yes, you can add sand to a garage floor sealer to improve traction. This is especially helpful if you’re sealing a concrete garage floor with a glossy epoxy or polyurea coating.
Use a fine-grit sand or a specialized non-slip additive. Mix it into the sealer during the application or broadcast it evenly onto the wet floor before the first coat cures.
This creates a textured finish that helps keep the surface from being slippery when wet.
Adding sand doesn’t impact the durability of the sealer. It works well in workshops or areas exposed to moisture.
What Temperature Does It Need to Be to Seal Concrete?
Sealing concrete requires the right temperature for the sealer to cure properly. Most garage floor sealers work best between 50°F and 90°F. Extreme temperatures can affect the finish.
If it’s too cold, the sealer won’t penetrate or bond correctly. This is especially true for penetrating sealers which rely on absorption into the concrete surface.
High temperatures can make topical sealers, like epoxy floor coatings, cure too quickly. This shortens the pot life and can leave uneven areas.
Check the product’s label for specific temperature guidelines. For example, Ghostshield recommends applying its best-selling sealers between 55°F and 85°F for optimal performance.
Make sure the concrete slab isn’t too hot from sun exposure. A surface that’s overly warm can evaporate the sealer too quickly, reducing coverage.
How Often Do You Have to Seal Concrete Floors?
The frequency of sealing depends on the type of sealer and how much traffic your floor gets. Penetrating sealers can last up to 10 years with minimal maintenance.
Garage floor coatings, such as epoxy or polyurea, typically need reapplication every 5 to 7 years in high-traffic areas.
Acrylic floor sealers, while more affordable, may require reapplication every 1 to 3 years. Heavy use in workshops or exposure to oil and moisture can shorten their lifespan.
Watch for signs that your sealer is wearing out. A dull surface, stains penetrating the concrete, or moisture intrusion are clear indicators. Proper prep and application extend the life of any garage floor sealer.
Choosing a durable, high-quality sealer reduces maintenance and keeps your concrete garage floor protected longer.
How Long Does a Concrete Sealer Smell?
The smell of a concrete sealer depends on the type you use. Solvent-based garage floor sealers, like polyurea or epoxy coatings, can emit strong odours for 24 to 48 hours.
Ventilation is key. Open windows, use fans or set up a server-style exhaust system to move air out of the space. Without airflow, the smell might linger longer, especially in enclosed garages.
Water-based sealers are nearly odourless and a better choice for indoor applications. They penetrate the concrete surface without leaving a heavy scent.
For solvent-based coatings, avoid staying in the area until the fumes dissipate. Permission to access should be delayed for safety, particularly in workshops or homes with sensitive individuals.
