How To Grout Vinyl Plank? (1 Wrong Way!)

Vinyl plank has exploded in popularity, and for good reason! It’s tough, looks great, and is relatively easy to maintain. We’re talking about a flooring option that can handle kids, pets, and even the occasional clumsy adult (I’m raising my hand here!). It’s resistant to scratches, stands up to heavy foot traffic, and laughs in the face of minor spills. But can you grout it? Should you grout it? And if so, how do you do it right?

Grouting vinyl plank isn’t something you have to do. It’s not like tile where grout is essential for structure and waterproofing. However, adding grout lines can really elevate the look of your vinyl plank, giving it a more authentic tile or stone appearance.

In this article, I’ll walk you through everything you need to know about grouting vinyl plank, from understanding the material itself to avoiding the one major mistake that can turn your dream floor into a nightmare. So, grab a coffee, settle in, and let’s get started!

Section 1: Understanding Vinyl Plank Flooring

Okay, let’s break down what we’re dealing with.

What is Vinyl Plank Flooring?

Vinyl plank flooring is a multi-layered synthetic flooring product designed to mimic the look of hardwood or tile. It’s typically made of four layers:

• Wear Layer: This is the top layer, a clear coating that protects the floor from scratches, stains, and wear. The thicker the wear layer, the more durable the plank. I usually recommend at least a 12 mil wear layer for residential use and 20 mil or higher for commercial spaces.

• Print Layer: This layer features the design, whether it’s a wood grain, stone pattern, or something else entirely. High-quality vinyl planks use realistic printing techniques that can fool even the most discerning eye.

• Core Layer: This is the main body of the plank, providing stability and water resistance. Cores can be made of different materials, including:

  • WPC (Wood Plastic Composite): This core is waterproof and provides a softer underfoot feel. It’s a great option for bathrooms, kitchens, and basements.

  • SPC (Stone Plastic Composite): This core is even more rigid and durable than WPC, making it ideal for high-traffic areas. It’s also more resistant to temperature changes.

• Backing Layer: This bottom layer provides cushioning and helps to absorb sound.

There are two main types of vinyl plank flooring:

• Luxury Vinyl Plank (LVP): This is the higher-end option, typically thicker, more durable, and with more realistic designs. LVP often features embossed textures that mimic the feel of real wood or stone.

• Standard Vinyl Plank: This is a more budget-friendly option, usually thinner and with simpler designs. It’s still a good choice for many applications, but it may not be as durable as LVP.

Advantages and Disadvantages

Like any flooring option, vinyl plank has its pros and cons.

Advantages:

• Durability: As I mentioned earlier, vinyl plank is tough. It can withstand a lot of wear and tear, making it a great choice for busy households.

• Water Resistance: Most vinyl plank is highly water-resistant, and some types are even waterproof. This makes it a good option for kitchens, bathrooms, and basements.

• Ease of Maintenance: Vinyl plank is easy to clean. Just sweep, vacuum, or mop with a mild detergent.

• Affordability: Compared to hardwood or tile, vinyl plank is relatively inexpensive.

• Easy Installation: Many vinyl plank products are designed for DIY installation, with click-lock systems that make it easy to put together.

Disadvantages:

• Not as Durable as Real Wood or Tile: While vinyl plank is durable, it’s not as long-lasting as real wood or tile. It can be scratched or dented by sharp objects or heavy furniture.

• Can Look Artificial: Some lower-quality vinyl plank can look obviously fake. However, high-end LVP can be very convincing.

• Difficult to Repair: If a vinyl plank is damaged, it can be difficult to repair. You may need to replace the entire plank.

Why Grout Vinyl Plank?

So, why would you want to grout vinyl plank in the first place? Here are a few reasons:

• Aesthetic Appeal: Grout lines can add a touch of realism to vinyl plank flooring, making it look more like tile or stone. This can be especially effective if you’re using vinyl plank that mimics the look of natural materials.

• Hiding Imperfections: Grout can help to hide minor imperfections in the vinyl plank installation, such as slight gaps or uneven edges.

• Creating a Custom Look: You can use different colors of grout to create a custom look that complements your decor. For example, you could use a dark grout with light-colored vinyl plank to create a dramatic contrast.

Aesthetic Options

When it comes to grouting vinyl plank, you have a lot of aesthetic options to choose from. Here are a few things to consider:

• Grout Color: The color of your grout can have a big impact on the overall look of your floor. You can choose a grout color that matches your vinyl plank for a seamless look, or you can choose a contrasting color for a more dramatic effect.

  I’ve seen some homeowners go bold with colors like blues or greens to really make their floor pop!

• Grout Width: The width of your grout lines can also affect the look of your floor. Narrow grout lines will create a more modern look, while wider grout lines will create a more traditional look. I typically recommend a grout width of 1/8 inch to 1/4 inch for vinyl plank.

• Grout Pattern: You can also create different grout patterns to add visual interest to your floor. For example, you could use a herringbone pattern or a checkerboard pattern.

Section 2: The Grouting Process

Alright, let’s get down to the nitty-gritty. Here’s how to grout vinyl plank the right way.

1. Preparation

Proper preparation is key to a successful grouting job. Don’t skip these steps!

Tools and Materials:

• Vinyl Plank Flooring: Obviously! Make sure it’s properly installed and adhered to the subfloor.

• Grout: Choose the right type of grout (more on that below).

• Grout Float: This is a rubber-faced tool used to apply grout evenly.

• Grout Sponge: You’ll need this to clean up excess grout.

• Buckets: One for mixing grout and one for rinsing your sponge.

• Clean Water: For mixing grout and cleaning.

• Measuring Tools: For measuring grout and water accurately.

• Painter’s Tape: To protect adjacent surfaces.

• Safety Glasses and Gloves: Always protect yourself!

Preparation Steps:

1. Clean the Floor: Before you start grouting, make sure the floor is clean, dry, and free of debris. Vacuum thoroughly and then wipe down the floor with a damp cloth.

   I often use a mild detergent to remove any stubborn dirt or grease. Make sure to rinse the floor well and let it dry completely before proceeding.

2. Protect Adjacent Surfaces: Use painter’s tape to protect baseboards, walls, and other surfaces that you don’t want to get grout on.

3. Mix the Grout: Follow the manufacturer’s instructions for mixing the grout. Add water gradually until you reach the desired consistency. The grout should be thick enough to hold its shape but still be workable.

   I like to use a mixing drill with a paddle attachment to ensure that the grout is thoroughly mixed.

Choosing the Right Grout:

This is where things get tricky. Choosing the right grout is crucial for a successful vinyl plank grouting job. Here’s what you need to know:

• Sanded vs. Unsanded Grout: Sanded grout contains sand, which makes it stronger and more resistant to cracking. However, it can scratch vinyl plank if not applied carefully. Unsanded grout is smoother and less likely to scratch, but it’s not as strong.

  I generally recommend using unsanded grout for vinyl plank, especially if the grout lines are narrow (1/8 inch or less). The risk of scratching the vinyl is just too high with sanded grout.

  If you’re using wider grout lines (1/4 inch or more), you could consider sanded grout, but be extra careful during application and cleanup.

• Epoxy vs. Cement-Based Grout: Epoxy grout is more expensive than cement-based grout, but it’s also more durable, water-resistant, and stain-resistant. It’s a good choice for wet areas like bathrooms and kitchens. Cement-based grout is more porous and may require sealing to protect it from stains and water damage.

  For vinyl plank, I usually recommend cement-based grout. It’s more affordable and generally sufficient for most applications. Just be sure to seal it properly after it cures.

2. Applying Grout

Now for the fun part!

1. Apply the Grout: Using a grout float, apply the grout to the seams between the vinyl planks. Hold the float at a 45-degree angle and press firmly to force the grout into the seams.

   Work in small sections at a time, and be sure to fill the seams completely.

2. Remove Excess Grout: After you’ve applied the grout, use the grout float to remove any excess grout from the surface of the vinyl planks. Hold the float at a 45-degree angle and scrape it across the surface of the planks.

   Be careful not to gouge or scratch the vinyl.

3. Clean with a Sponge: Using a damp grout sponge, gently wipe the surface of the vinyl planks to remove any remaining grout residue. Rinse the sponge frequently in clean water.

   Don’t use too much water, as this can weaken the grout.

4. Repeat: Repeat steps 1-3 until you’ve grouted the entire floor.

Grout Joint Width:

Maintaining a consistent grout joint width is crucial for a professional-looking result.

• Use Spacers: If you’re installing the vinyl plank yourself, use spacers to ensure that the grout joints are uniform. You can find spacers at most home improvement stores.

• Be Consistent: Pay attention to the grout joint width as you’re applying the grout. If you notice any areas where the grout joints are too wide or too narrow, adjust accordingly.

Common Mistakes to Avoid:

• Overfilling Grout Lines: Don’t overfill the grout lines. This can make it difficult to clean the grout and can also cause the grout to crack.

• Using Too Much Water: As I mentioned earlier, using too much water when cleaning the grout can weaken it.

• Letting Grout Dry on the Surface: Don’t let the grout dry on the surface of the vinyl planks. This can make it difficult to remove and can also stain the vinyl.

3. Finishing Touches

Almost there! These final steps will ensure a long-lasting, beautiful result.

Cleaning Excess Grout:

Even after wiping with a sponge, you may still have some grout haze on the surface of the vinyl planks. Here’s how to remove it:

• Use a Grout Haze Remover: You can find grout haze removers at most home improvement stores. Follow the manufacturer’s instructions for application.

• Use a Vinegar Solution: If you don’t want to use a chemical remover, you can try using a solution of vinegar and water. Mix equal parts vinegar and water and apply it to the surface of the vinyl planks. Let it sit for a few minutes and then wipe it away with a clean cloth.

Curing the Grout:

Grout needs time to cure properly.

• Drying Time: Allow the grout to dry for at least 24 hours before walking on it. Avoid heavy traffic or placing furniture on the floor during this time.

• Conditions: Keep the room well-ventilated and avoid exposing the grout to extreme temperatures or humidity.

Sealing the Grout:

Sealing the grout is essential to protect it from stains and water damage.

• Choose a Sealer: Choose a grout sealer that is appropriate for the type of grout you’re using.

• Apply the Sealer: Follow the manufacturer’s instructions for applying the sealer. Typically, you’ll apply the sealer with a brush or applicator pad and let it dry for the recommended time.

  I usually recommend applying two coats of sealer for maximum protection.

Section 3: The Wrong Way to Grout Vinyl Plank

Okay, let’s talk about the one big mistake that people make when grouting vinyl plank. And believe me, I’ve seen it happen more times than I can count.

The Mistake: Using the Wrong Grout (or Applying It Incorrectly!)

I know I’ve already touched on this, but it’s so important that it bears repeating. The biggest mistake you can make is using sanded grout on vinyl plank flooring.

As I mentioned earlier, sanded grout contains sand, which can scratch the surface of the vinyl. Even if you’re careful during application, it’s almost impossible to avoid scratching the vinyl completely.

But it’s not just about the type of grout. Applying any grout incorrectly can also lead to problems. This includes:

• Using too much water when mixing the grout. This can weaken the grout and make it more prone to cracking.

• Not filling the grout lines completely. This can leave gaps where water can seep in.

• Letting the grout dry on the surface of the vinyl. This can stain the vinyl and make it difficult to remove.

Consequences of the Mistake:

So, what happens if you use the wrong grout or apply it incorrectly? Here are a few possible consequences:

• Scratched Vinyl: This is the most common problem. Sanded grout can leave unsightly scratches on the surface of the vinyl planks.

• Cracked Grout: If the grout is too weak or not properly applied, it can crack over time.

• Water Infiltration: Gaps in the grout can allow water to seep under the vinyl planks, which can lead to mold and mildew growth.

• Stained Vinyl: Letting grout dry on the surface of the vinyl can stain it, especially if you’re using a dark-colored grout.

• Aesthetic Issues: Even if none of the above problems occur, improper grouting can simply make your floor look bad. Uneven grout lines, inconsistent color, and a generally sloppy appearance can detract from the overall look of your home.

Case Study: The Kitchen Catastrophe

I once had a client who decided to grout her vinyl plank kitchen floor herself. She’d seen some tutorials online and thought it looked easy enough. Unfortunately, she didn’t do her research properly and ended up using sanded grout.

The result? The entire floor was covered in fine scratches. It looked like she’d taken sandpaper to it!

She called me in a panic, and I had to break the bad news: the only way to fix the problem was to replace the entire floor. It was a costly and time-consuming mistake that could have been easily avoided.

Conclusion

So, there you have it! Everything you need to know about grouting vinyl plank flooring.

Let’s recap the key points:

• Vinyl plank is a durable and versatile flooring option that can be enhanced with grout.

• Choosing the right grout is crucial. I recommend using unsanded grout for vinyl plank to avoid scratching.

• Proper preparation is essential. Clean the floor, protect adjacent surfaces, and mix the grout according to the manufacturer’s instructions.
