11 Things You Can Put on Laminate Flooring to Make It Waterproof?

what can you put on laminate flooring to make it waterproof

Waterproofing your laminate flooring is critical to maintain its durability and aesthetic value. Despite its popularity as a cost-effective and versatile option for homeowners, laminate flooring is not naturally waterproof.

Left unprotected, it can be susceptible to damage from moisture and spills, leading to costly repairs or replacements.

However, there are practical solutions to this challenge. In this article, we will explore 11 different products and techniques you can apply to your laminate flooring to make it waterproof, increasing longevity and preserving its beauty over time.

Waterproof Laminate Flooring

What is Laminate Flooring Made Of?

As a flooring enthusiast, I find laminate flooring fascinating. It’s a multi-layer synthetic product fused in a lamination process.

The four main layers are the wear layer, the design layer, the inner core layer, and the backing layer. The wear layer contains aluminum oxide and provides resistance against wear and tear.

The design layer is what gives your floor its aesthetic appeal. The inner core layer, usually made of high-density fiberboard, provides stability, and the backing layer keeps everything aligned and prevents moisture from seeping upwards.

Why is Laminate Flooring Not Naturally Waterproof?

Now, you might ask, “Why isn’t this product naturally waterproof?” Well, the answer lies in the inner core layer.

Despite its many benefits, the high-density fiberboard in the core is highly susceptible to moisture. I remember how shocked I was when I first learned this during my early days of navigating the flooring world.

A single spill left unattended can cause the fiberboard to absorb moisture, leading to swollen planks and a ruined floor.

Adding a Protective Layer for Waterproofing

Given these issues, it’s clear why many of us search for a solution to make laminate flooring waterproof.

Enter the concept of adding a protective layer for waterproofing. I once had a client who ran a busy café, and, trusts me, spillages were a daily occurrence.

By adding a waterproof layer to her café’s laminate floor, we significantly extended its life, saving her from the frequent, costly repairs almost becoming a norm.

These protective layers are a barrier, preventing moisture from reaching the vulnerable core.

And that, my friends, is how we can enjoy the beauty and affordability of laminate flooring without worrying about water damage.

What Can You Put on Laminate Flooring to Make It Waterproof?

1. Water-Resistant Underlayment

Underlayment plays a pivotal role in the longevity and durability of your laminate flooring.

Think of it as a guardian, tirelessly working beneath the surface to protect your floor from moisture damage.

In my years of experience, I’ve learned that investing in a good underlayment can make a difference.

Underlayment in Laminate Flooring

The underlayment for laminate flooring is like the unsung hero of a successful flooring project.

Not only does it provide additional comfort and sound insulation, but it also forms a crucial moisture barrier.

I once had a client who skipped on underlayment to save some bucks. Trust me, the result was far from ideal.

The moisture seeping up from his concrete subfloor led to warped planks, and he had to replace the entire floor within a year.

Types of Water-Resistant Underlayment

  1. Rubber Underlayment

Rubber underlayment is a reliable choice for combating moisture. It’s dense, durable, and provides excellent sound reduction – ideal for environments where noise is a concern.

I recommended this to a client with an at-home fitness studio. The rubber underlayment not only protected his laminate flooring from sweat and spilled water bottles, but it dampened the sound of his workouts, much to his downstairs neighbors’ relief.

  1. Cork Underlayment

Then comes cork underlayment, a favorite of eco-conscious clients. Cork is naturally resistant to mold, mildew, and rot – all moisture-induced.

It’s also a renewable material, making it an excellent choice for those looking to make sustainable choices.

I remember a client who was passionate about green choices. I suggested cork underlayment for her laminate flooring.

She loved it as it aligned with her values and kept her floor safe from water damage.

Advantages of Using Water-Resistant Underlayment

Using a water-resistant underlayment gives you peace of mind. It’s like having an insurance policy against moisture damage.

You also benefit from added comfort and sound insulation. It might seem like an extra expense at the start, but believe me, it’s a wise investment that can save you from costly repairs in the future.

For those who love the look and affordability of laminate flooring, water-resistant underlayment is the secret ingredient to achieving a beautiful, long-lasting floor.

2. Seal the Joints and Edges

Sealing the joints and edges of your laminate flooring is a critical yet often overlooked step in protecting your investment from water damage.

How Water Seeps Through the Joints and Edges

Even after installing a water-resistant underlayment, the threat of moisture isn’t eliminated. Water can be a crafty adversary, finding its way through the most minor cracks and crevices.

The most vulnerable points are the joints and edges of your laminate flooring. I once had a client who had installed a top-quality underlayment but neglected to seal the joints.

Within a few months, water had seeped in, causing the laminate to warp and the beautiful floor to lose appeal.

The Use of Seam Sealer

Here’s where the use of a seam sealer comes into play. Seam sealers create a waterproof barrier that prevents moisture from seeping through the joints.

I’ve found it an effective solution in my years of experience. One of my clients had a high-traffic commercial space where spillage was a regular occurrence.

After applying a seam sealer, he noticed significantly reduced water damage incidents.

The Importance of Properly Sealing the Joints and Edges

Properly sealing the joints and edges of your laminate flooring is truly a game-changer. It enhances the longevity of your floors and maintains their aesthetic appeal.

A friend learned this the hard way; she had to replace her entire floor due to water damage from improperly sealed joints.

After replacement, we used a high-quality sealer, and she hasn’t had a water issue since – testament to the importance of this often overlooked step.

3. Waterproofing with Wax

Waterproofing solutions come in various forms, and one such solution that I’ve come across, albeit not as frequently, is the use of wax.

Yes, you heard it right, wax! Just like you’d wax a car to maintain its shine and shield it from external elements, you can apply a layer of wax to your laminate flooring for water protection.

Applying Wax to the Flooring

The wax application process is straightforward, but do pay attention to details. Begin with a clean, dry floor.

Use a soft cloth or mop to spread a thin layer of wax on the surface of the laminate, following the grain of the wood. Work in small sections to ensure an even coat.

Allow the wax to dry (anywhere from 10 to 30 minutes, depending on the brand of wax), then buff it with a clean, dry cloth to bring out the shine.

Remember, the goal is not to make the floor slippery but to provide a protective layer.

Advantages of Using Wax

One of the main advantages of using wax is that it adds a protective layer that repels water, reducing the risk of water damage.

It also enhances the floor’s shine, lending an appealing sheen to make your laminate look as good as new.

I recall when I first tried wax on a worn-out floor in my living room. I was amazed at how it returned the shine and made the floor look freshly installed.

Disadvantages of Using Wax

However, using wax is not without its drawbacks. Wax cannot be used on all types of laminate flooring, especially those with a glossy finish.

It can also make the floor slippery if over-applied, a risk, particularly in homes with kids or elderly residents.

Lastly, the wax protection isn’t permanent. It wears off with time and traffic, necessitating regular reapplication.

So, while the idea of waxing might sound like a perfect solution, it’s essential to weigh these considerations before deciding to wax your laminate floors.

4. Waterproof Laminate Flooring

While exploring flooring options, I came across a gem that is waterproof laminate flooring.

It completely reshaped my understanding of laminate floors. Let me share with you my experiences and insights.

Waterproof Laminate Flooring

When I first moved to my new house in Seattle, where rain is as regular as clockwork, waterproof flooring was paramount.

One day, while shopping at a local home improvement store, I stumbled upon waterproof laminate flooring.

It’s a remarkable engineering marvel where each piece is designed to withstand water penetration.

Unlike traditional laminate, the waterproof variety has a layer that repels water, preventing it from seeping through the gaps and causing damage.

Benefits of Waterproof Laminate Flooring

Having lived with waterproof laminate flooring for a few years, I can vouch for its advantages. The most significant benefit for me is peace of mind.

No more worrying about the kids spilling their drinks or the dog tracking in mud and water. Cleaning up is easy – a quick wipe-down, and it’s as good as new.

Also, it’s a fantastic mimic of the aesthetics of hardwood or stone flooring, but at a fraction of the cost. It truly combines style and practicality in perfect harmony.

Considering the Cost Factor

When I first considered waterproof laminate, the cost was a significant factor. Yes, it’s pricier than traditional laminate flooring, and I had to stretch my budget a bit.

But when I factored in durability, longevity, and the potential savings from avoiding water damage repairs, it was worth it.

Over the years, this investment has paid off. So, if you’re considering flooring options and water is a concern, I’d highly recommend giving waterproof laminate flooring a thought. It’s an investment you won’t regret.

5. Polyurethane Coating

Polyurethane coating is a high-performance surface finish used to protect and add longevity to a wide range of materials.

It forms a hard, durable film over the material to shield it from damage, making it particularly useful for flooring.

I remember the first time I encountered polyurethane coating. I was in awe of the transformation it brought about – turning a dull surface into a glossy, robust finish that screamed quality and refinement.

The Application Process and Precautions

The application of polyurethane coating is a task that demands careful preparation and execution.

Let me take you back to when I decided to apply it to my wooden floor. The first step was to ensure the surface was clean and well-sanded.

Once prepped, I mixed the polyurethane carefully, following the manufacturer’s instructions.

Then, using a good quality brush, I applied thin, even strokes along the wood grain. It’s important to ventilate the room well during this process, as the fumes can be intense.

Benefits of Using Polyurethane Coating

One of the significant benefits I’ve discovered with using polyurethane coating is the remarkable resistance it offers against wear and tear.

It’s been a few years since I applied it to my wooden floors, and they still look as good as new despite numerous parties, pet antics, and everyday traffic.

Not only does it protect the floor, but it also enhances its natural beauty, and the glossy finish is a real eye-catcher.

To top it all off, cleaning is a breeze – a simple sweep and mop, and the floor is back to its sparkling best.

So, if you’re considering a durable and aesthetically pleasing finish for your floors, polyurethane coating is an option worth exploring.

6. The Magic of Silicone Caulk

Oh, the wonders of silicone caulk! This nifty material has been a lifesaver in my home repairs journey.

It’s primarily used to seal gaps and cracks in various parts of your home. From the bathroom to the kitchen, windows to doors, silicone caulk is your go-to solution for preventing water and air leaks.

Silicone Caulk

I still remember the first time I used silicone caulk. It was to fix a nagging leak around my kitchen sink.

The previous sealant had worn off, and I needed something sturdy and waterproof. Enter silicone caulk – a flexible yet robust sealant that can resist water, temperature changes, and mildew.

Applying Silicone Caulk

Applying silicone caulk is not rocket science, but it does take a bit of skill and patience. Here’s my tried-and-tested method: start by cleaning and drying the area you intend to caulk.

Next, cut the caulk tube’s tip at an angle, load it into a caulk gun (a tool that’s made caulking jobs a breeze for me), and apply a smooth, steady bead of caulk to the desired area.

Remember to smooth the bead with a caulk finishing tool or your finger for a neat finish. Let it dry, and voila! You’ve sealed the gap!

Weighing the Pros and Cons

Like all things, silicone caulk has its pros and cons. Plus, it’s waterproof, flexible, and resistant to weather changes.

It’s been years since I fixed my kitchen sink, and the caulk is holding up admirably with no signs of cracking or shrinking. However, it has its drawbacks, too.

Silicone caulk can be challenging to apply neatly, and it doesn’t take paint well. In my experience, though, its advantages far outweigh these minor inconveniences.

When applied correctly and carefully, silicone caulk can be a game-changer in home repair tasks.

7. Waterproof Rugs and Mats

Waterproof rugs and mats are more than just decorative items – they’re functional, too. I’ve found them invaluable over the years, especially in rooms with a lot of water, like the kitchen and bathroom.

These rugs protect my floors from water damage, and the added traction they provide makes slipping less likely.

The last thing I want is to be the star of my home-based sitcom, slipping on a wet floor!

Types of Waterproof Rugs and Mats

There are a plethora of options available when it comes to waterproof rugs and mats. For instance, there are vinyl-backed mats that are great at trapping water and dirt.

They’re incredibly durable and easy to clean – a quick swipe, and they’re good as new. Then there are rubber mats, popular in bathrooms and kitchens due to their high water and slip resistance.

I particularly love cotton bath mats; they’re soft, absorbent, and quick-drying. And let’s not forget the outdoor mats, usually made from polypropylene or coir, which bravely endure rain, snow, and muddy shoes!

Choosing the Right Size and Style

Choosing the right size and style of a waterproof rug or mat can be a tricky task. I always start by measuring the space I have.

For instance, in my bathroom, I needed a compact mat to fit in front of the shower. In the kitchen, however, I had more freedom and went with a longer, runner-style mat.

Style is a personal choice, but I advise going with something that complements your decor. I have a rustic theme in my kitchen, so I opted for a mat with warm, earthy tones.

Remember, these rugs and mats are functional and aesthetic elements in your home as well!

8. Laminate Floor Sealer

Have you ever heard of a laminate floor sealer? If not, allow me to introduce you to your floor’s new best friend.

Essentially, laminate floor sealer is a protective coating applied to laminate floors to prevent damage from water, scratches, and even UV light.

Imagine it as a shield, acting as the first line of defense, ensuring your floors’ longevity.

Applying Laminate Floor Sealer and Maintenance

Trust me when I say the application process is far from rocket science. It’s a simple DIY task that requires a clean floor, a quality sealer, and a bit of patience.

Start by thoroughly cleaning your floor, ensuring no dust or debris. Then, apply the sealer evenly using a mop or a roller – I find a roller easier to use, personally.

Let it dry, and voila, your floor is now shielded! As for maintenance, a regular sweep and mop, using a gentle cleaner, will keep the sealed floor looking fresh and new.

Pros of Using Laminate Floor Sealer

The benefits of laminate floor sealer are numerous. Firstly, it’s a fantastic way to extend the life of your floors, protecting them from spills, scuffs, and scratches.

I remember when I first used it in my old apartment; I was amazed at how it maintained the floor’s shine and texture despite constant foot traffic.

Plus, it’s easy to apply and makes cleaning much more accessible, saving you time and energy.

Cons of Using Laminate Floor Sealer

However, I believe in balanced perspectives, so let’s discuss some downsides. One of the main drawbacks is that once applied, removing a sealer can be challenging work if you wish to change it later.

Also, not all sealers are created equal, and cheaper ones may not provide the protection you need.

Lastly, while most sealers are clear, some might slightly alter your floor’s color, so it’s essential to test a small area before you apply it throughout.

However, I’ve found that the pros of using a laminate floor sealer far outweigh the potential cons.

9. Water-Resistant Adhesive

Water-resistant adhesive for laminate flooring is another essential tool in my flooring toolkit.

This specific type of adhesive is designed to resist water penetration, which is particularly useful for those areas of your home that are prone to getting wet, like the bathroom or kitchen.

Water-Resistant Adhesive

Water-resistant adhesive, as the name suggests, is a bond that can withstand the occasional splash or spillage.

This adhesive creates a barrier preventing water from seeping into the cracks between your laminate tiles, protecting the underlying floor and the laminate itself from water damage.

When I first used it in my parent’s kitchen, they were worried about spills causing warping or discoloration. This adhesive was the perfect solution.

Proper Application of Adhesive

Applying the adhesive requires precision and patience. Not too different from sealing, you need a clean surface.

Apply a thin, even layer of adhesive on the floor, then lay your laminate tile on top. Be careful not to apply too much – you don’t want it seeping out the sides!

It takes a little practice, but once you get the hang of it, it’s a relatively straightforward process.

Advantages and Considerations

The most significant advantage of water-resistant adhesive is, of course, its water resistance. It offers protection for your floors, especially in high-moisture areas.

Besides this, it also helps to secure the tiles more firmly, reducing movement and thus the risk of damage over time.

As for considerations, proper ventilation is essential when working with adhesives due to the fumes.

Also, remember to give it ample time to dry; rushing the process can compromise the adhesive’s efficacy.

Despite these minor considerations, I’ve seen first-hand that the benefits of using water-resistant adhesive are plentiful, and the peace of mind it provides is priceless.

Regular Maintenance and Cleaning

Like a finely tuned vehicle, your laminate floor thrives on regular upkeep. Think of maintenance as a small investment that pays dividends in the long run, preserving the shine and durability of your laminate for years to come.

Importance of Regular Upkeep

There’s an old saying I love that goes, “Take care of the pennies, and the pounds will take care of themselves.”

I think this sentiment applies perfectly to laminate flooring. Small, regular actions to maintain your floor can prevent big problems down the line.

For instance, I once had a friend who neglected the maintenance of their laminate floor. Over time, the lack of cleaning led to a buildup of grime and dust, causing the laminate to lose its shine and the protective sealant to wear off.

The floor started showing warping and discoloration, and the previously beautiful laminate tiles looked dull and worn.

Regular upkeep isn’t just about keeping your floor looking good; it extends its lifespan and maintains its water-resistant properties.

If you’ve invested time and effort into installing and sealing your laminate floor correctly, regular maintenance is the key to protecting that investment.

Tips on Cleaning and Maintaining Waterproofed Laminate Flooring

Now, you might be wondering, “Okay, I understand the value of regular upkeep, but how exactly do I go about it?” Well, here are some tips and tricks I’ve picked up over the years:

  1. Use a Soft Broom for Daily Sweeping: Regular sweeping prevents the buildup of dirt and dust that can scratch the surface of your laminate. I prefer using a soft broom to avoid any potential damage.
  2. Mop with a Damp Cloth or Mop, Not a Wet One: A common mistake is people mopping laminate with a soaking wet mop. This can cause water to seep into the cracks and cause damage, even if the floor is sealed. Use a damp cloth or mop instead.
  3. Avoid Harsh Cleaners: Some cleaning agents can damage the sealant on your laminate. I usually stick to a mixture of vinegar and warm water for a safe, natural cleaning solution.
  4. Attend to Spills Immediately: Even with the most effective sealants and adhesives, it’s best to clean up spills as soon as they happen. I say this from experience – I once spilled a glass of red wine and was slow to clean it up. Even though my floor was sealed, the wine left a faint stain that took some elbow grease to remove!
  5. Consider Professional Cleaning: Every once in a while, especially for larger spaces, it might be worth getting a professional cleaning service. They have specialized equipment and products to give your laminate a deep clean without damaging it.

Like any other aspect of home care, a bit of effort goes a long way when maintaining your laminate flooring. Trust me, your floors will thank you!


To encapsulate, we’ve dug into numerous ways to protect our beloved laminate floors from the bane of water damage.

Regular cleaning with a soft broom and a damp mop, swift action on spills, and the cautious use of gentle, non-abrasive cleaners are fundamental care practices that have saved my floor countless times.

And then there are the heavy hitters – sealants, waterproof underlayment, silicone caulks, and even professional cleaning services.

I remember thinking my floor was a goner due to a massive water leak, but a correctly applied sealant saved the day.

Remember, laminate flooring, while durable and aesthetically pleasing, is fundamentally a wood product and is, therefore, susceptible to water damage.

Over the years, I’ve learned that no amount of appeal can compensate for the heartbreak and cost of a water-damaged floor. Trust me, the sight of a swelling, peeling floor is one you’ll want to avoid.

Finally, it’s your turn to choose your best defense against moisture. Maybe you’re a fan of the DIY approach and eager to perform your sealing.

Perhaps your busy schedule means a professional cleaning service is a more practical option. I encourage you to pick whichever method suits your needs, preferences, and lifestyle.

I once tried hiring professionals due to a hectic week, and although it was a bit more expensive, the exceptional results and convenience were worth every penny.

The choice is yours. Give your laminate floors the love and protection they deserve, and they will repay you with years of beauty and durability.
