Concrete Board As Flooring? (2 Install Mistakes!)

And let me tell you, I’ve seen it all!

Today, we’re diving into the world of concrete board flooring.

It’s a material that’s been gaining popularity, and for good reason.

And guess what? I’m here to spill the beans on the two biggest installation mistakes I see time and time again.

But before we get to the nitty-gritty, let’s talk about something near and dear to my heart: allergies.

The Allergies Connection

In today’s world, allergies are more common than ever.

I mean, it seems like everyone knows someone who’s battling sniffles, sneezes, or worse.

And a lot of times, these allergies are exacerbated by what’s going on inside our homes.

Think about it: poor indoor air quality, dust mites, mold, pet dander—it’s a cocktail of allergens just waiting to wreak havoc.

That’s why choosing the right flooring is so crucial.

We want materials that minimize allergens, are easy to clean, and contribute to a healthy indoor environment.

Enter concrete board.

It’s durable, moisture-resistant, and can actually be a great choice for allergy sufferers.

But here’s the kicker: if it’s not installed correctly, you could be setting yourself up for a whole host of problems.

And trust me, I’ve seen those problems firsthand.

So, stick with me as we explore concrete board flooring, its benefits, and those two critical installation mistakes that can turn your dream floor into an allergy nightmare.

Section 1: Understanding Concrete

Board as Flooring

Alright, let’s get down to brass tacks.

What exactly is concrete board, and why should you even consider it for your floors?

What is Concrete Board?

Concrete board, also known as cement board, is a composite material made from cement, aggregate, and reinforcing fibers.

Think of it as a super-tough, moisture-resistant panel that can be used in a variety of construction applications.

You’ll often find it used as a backer board for tiles in bathrooms and kitchens, but it’s also gaining traction as a flooring option in its own right.

Why?

Well, it’s incredibly durable and resistant to moisture, mold, and pests.

Unlike wood, it won’t rot or warp when exposed to water, making it a fantastic choice for damp environments like basements or bathrooms.

Plus, it’s dimensionally stable, meaning it won’t expand or contract significantly with temperature changes.

Now, you can use concrete board as a subfloor, providing a solid base for other flooring materials like tile or vinyl.

Or, you can use it as a finished flooring surface, giving your space a modern, industrial look.

Either way, it’s a versatile material with a lot to offer.

Benefits of Using Concrete Board

for Flooring

So, why should you choose concrete board over other flooring options?

Let me break it down for you:

Durability: This stuff is tough! It can withstand heavy foot traffic, impacts, and even the occasional dropped object without showing signs of wear and tear.
Ease of Maintenance: Concrete board is super easy to clean. Just sweep or mop it regularly, and you’re good to go. No need for special cleaners or treatments.
Longevity: With proper installation and maintenance, concrete board flooring can last for decades. It’s a long-term investment that will pay off in the long run.
Stability: Concrete board creates a stable and level surface, which is essential for preventing cracks and other issues in your finished floor.
Thermal Mass: Concrete has excellent thermal mass properties, meaning it can absorb and store heat. This can help regulate the temperature in your home and reduce your energy bills. According to the U.S. Department of Energy, using materials with high thermal mass can reduce heating and cooling costs by up to 50% in some climates. (Source: U.S. Department of Energy)
Versatility: Concrete board is suitable for a wide range of environments, from basements and kitchens to bathrooms and even outdoor patios.

I’ve seen it used in everything from modern lofts to rustic farmhouses, and it always looks fantastic.

But remember, all these benefits are contingent on one thing: proper installation.

And that’s where things can get tricky.

Section 2: Common Install Mistakes

with Concrete Board Flooring

Okay, we’ve covered the basics of concrete board and its benefits.

Now, let’s get to the heart of the matter: the two biggest installation mistakes I see that can turn your dream floor into a nightmare.

And it’s a big one!

Think of the subfloor as the foundation of your entire flooring system.

If it’s not properly prepared, you’re setting yourself up for problems down the road.

So, what does adequate subfloor preparation entail?

Well, it involves several key steps:

Cleaning: You need to start with a clean slate. Remove any debris, dirt, dust, or old adhesive from the subfloor. I recommend vacuuming thoroughly and then wiping down the surface with a damp cloth.
Leveling: This is crucial! Concrete board needs to be installed on a level surface to prevent cracking and ensure a smooth, even floor. Use a self-leveling compound to fill in any low spots or uneven areas.
Moisture Testing: Moisture is the enemy of any flooring system. Before installing concrete board, you need to test the moisture content of the subfloor. I use a moisture meter to get an accurate reading. If the moisture level is too high, you’ll need to take steps to dry out the subfloor before proceeding.

Now, what happens if you neglect these steps?

Well, here are some of the consequences:

Uneven Surfaces: If the subfloor isn’t level, your concrete board will be uneven as well. This can lead to tripping hazards and an unsightly finished floor.
Cracking: Uneven surfaces can also cause the concrete board to crack over time, especially in areas with heavy foot traffic.
Moisture Problems: If the subfloor is damp, the moisture can seep into the concrete board and cause mold growth. This is a major health hazard and can lead to serious allergy problems.
Adhesive Failure: If the subfloor isn’t clean, the adhesive used to install the concrete board may not bond properly. This can cause the boards to come loose over time.

And let’s not forget about the allergy connection.

Trapped moisture and contaminants in the subfloor can create a breeding ground for mold and dust mites, which are major allergens.

According to the EPA, indoor mold growth can cause a variety of health problems, including allergic reactions, asthma attacks, and respiratory infections. (Source: EPA)

So, skimping on subfloor preparation is not only a bad idea for your floor, but it’s also a bad idea for your health.

Mistake #2: Improper Sealing and Finishing

Okay, let’s say you’ve done a stellar job preparing the subfloor.

You’re halfway there!

But the job’s not done yet.

The next crucial step is sealing and finishing the concrete board.

And this is another area where I see a lot of mistakes.

Why is sealing so important?

Well, concrete board is porous, meaning it can absorb moisture.

And as we’ve already discussed, moisture is the enemy.

Sealing the concrete board helps to prevent moisture infiltration, protecting it from mold growth and deterioration.

It also helps to create a more durable and stain-resistant surface.

Now, there are several different types of sealants you can use for concrete board, including:

Acrylic Sealers: These are water-based sealers that are easy to apply and provide good protection against moisture.
Epoxy Sealers: These are more durable than acrylic sealers and offer excellent resistance to chemicals and stains.
Polyurethane Sealers: These are the most durable type of sealant and provide the best protection against abrasion and wear.

The type of sealant you choose will depend on your specific needs and the environment where the concrete board is installed.

For example, if you’re installing concrete board in a bathroom, you’ll want to use a sealant that’s highly resistant to moisture and mold.

Now, here’s where things can go wrong.

Improper sealant application can lead to a whole host of problems, including:

Deterioration of the Board: If the sealant isn’t applied properly, moisture can still seep into the concrete board, causing it to deteriorate over time.
Increased Susceptibility to Mold and Allergens: If the sealant is cracked or damaged, it can create a breeding ground for mold and dust mites.
Peeling or Chipping: If the sealant isn’t applied to a clean, dry surface, it may peel or chip over time.

And let’s not forget about the potential health implications.

Unsealed concrete board can emit volatile organic compounds (VOCs), which are chemicals that can cause a variety of health problems, including headaches, dizziness, and respiratory irritation.

According to the CDC, exposure to VOCs can cause a range of health effects, from mild irritation to more serious conditions like cancer. (Source: CDC)

So, sealing your concrete board is not just about protecting your floor; it’s also about protecting your health.

Section 3: Real-Life Case Studies

Alright, we’ve covered the theory.

Now, let’s take a look at some real-life examples of what can happen when concrete board flooring is installed improperly.

Case Study 1: A Family with Allergies

I once worked with a family who were desperate to find a flooring solution that wouldn’t aggravate their allergies.

They had two young children, both of whom suffered from asthma and eczema.

They decided to go with concrete board flooring in their basement, hoping it would be a healthier alternative to carpet.

Unfortunately, they hired a contractor who didn’t have much experience with concrete board.

He skipped several crucial steps, including leveling the subfloor and properly sealing the concrete board.

Within a few months, the family started noticing problems.

The concrete board was cracking in several places, and there was a musty odor in the basement.

The children’s allergy symptoms also got worse.

They were constantly coughing and wheezing, and their eczema was flaring up.

I was called in to investigate, and it quickly became clear that the installation was the problem.

The subfloor was uneven, and the concrete board hadn’t been properly sealed.

Moisture had seeped into the board, creating a breeding ground for mold.

The family was devastated.

They had spent a lot of money on the flooring, thinking it would improve their health.

Instead, it had made things worse.

We had to rip out the entire floor, level the subfloor, and install new concrete board with proper sealing.

It was a costly and time-consuming process, but it was essential for the family’s health.

Hire a contractor who knows what they’re doing and who will take the time to do the job right.

Case Study 2: A Commercial Space

I also worked on a commercial project where concrete board flooring was installed in a retail space.

The business owner was excited about the modern, industrial look of the concrete board.

He thought it would be a great way to attract customers and create a unique atmosphere.

However, he made the mistake of hiring a contractor who didn’t understand the nuances of concrete board installation.

The contractor rushed the job, skipping several important steps.

He didn’t properly prepare the subfloor, and he didn’t use the right type of sealant.

Within a few months, the concrete board started to show signs of wear and tear.

It was cracking in several places, and the surface was becoming stained and discolored.

Employees and customers started complaining about the air quality in the store.

Some people reported headaches, dizziness, and respiratory irritation.

The business owner was horrified.

He realized that the flooring was not only unsightly but also potentially harmful to people’s health.

He had to shut down the store for several days to have the flooring replaced.

It was a major setback for his business, both financially and reputationally.

The moral of the story is that you need to do your research and hire a contractor who has experience with concrete board installation.

Don’t just go with the cheapest option.

Invest in quality workmanship, and you’ll save yourself a lot of headaches in the long run.

Section 4: Summary and Conclusion

Okay, we’ve covered a lot of ground in this article.

Let’s recap the key points:

Concrete board is a durable, moisture-resistant flooring option that can be a great choice for allergy sufferers.
However, improper installation can lead to a variety of problems, including uneven surfaces, cracking, moisture problems, and mold growth.
The two biggest installation mistakes I see are inadequate preparation of the subfloor and improper sealing and finishing.
These mistakes can not only damage your floor but also create a breeding ground for allergens and expose you to harmful VOCs.
Real-life case studies show that these problems can have serious consequences for both residential and commercial spaces.

So, what’s the takeaway?

If you’re considering concrete board flooring, it’s essential to do your homework and hire a qualified contractor who understands the nuances of concrete board installation.

Don’t cut corners on subfloor preparation or sealing.

Invest in quality materials and workmanship, and you’ll be rewarded with a beautiful, durable, and healthy floor that will last for years to come.

Remember, your floor is an investment in your home and your health.

Take the time to do it right, and you’ll enjoy the benefits for years to come.
