The guide also explains how to caulk your vinyl floor, as well as the most common mistakes people make while caulking their floors and how to avoid them. But first, you should know what type of caulk is best for your vinyl flooring?
What Type of Caulk is Best for Vinyl Flooring?
Choosing the right caulk for vinyl flooring can be tricky because there are many types. But if you understand what caulk is, you will be able to choose the right caulk. Caulk is a silicone-based sealant used to fill and seal gaps around ceramic tile, metal, or glass.
Before deciding what type of caulk is best for you, it will be wiser to learn about each kind and choose the one that’s best for your vinyl flooring.
1. Acrylic Latex Caulk (Best for Indoors)
Acrylic latex caulk is a flexible sealant that is used in a wide range of applications to seal joints and gaps. It combines the properties of both acrylic and latex.
Furthermore, it is a flexible sealant that can be applied easily to most surfaces, including floors, walls, and ceilings. It is also a great alternative to silicone caulks since it does not require any special tools or skills for application.
2. Silicone Caulk (Best for Both Indoor & Outdoors)
Silicone caulk is a type of sealant that is used to fill gaps and seal cracks in the building, plumbing, and automotive industries. It can be applied both to inside and outside surfaces. These are usually white or clear in color, but they can also come in other colors if desired.
Silicone caulk is most commonly used in kitchens and bathrooms, but it can also be used on windows and decks. Since it is waterproof, it won’t shrink or crack when exposed to water.
In comparison to other types of caulks, they are extremely durable and long-lasting.
3. Foam Caulk (Best for Indoors)
Foam caulk is a sealant that is not made of traditional liquid sealant. It comes in a can and expands to fill gaps and cracks. Compared to the traditional liquid sealant, it is easier to apply, resistant to water, and doesn’t require special tools or skills.
Moreover, foam caulk is a type of caulking that uses expanding foam as the sealing agent instead of a liquid sealant. It has been around for years but only recently has become popular among consumers due to its many advantages over traditional caulking methods such as ease of application and resistance to water damage.
4. Butyl-Rubber Caulk (Best for Outdoors)
Butyl rubber caulk is a flexible watertight sealant used to stop leaks and cracks in a home. It dries into a flexible seal that can be used around windows, doors, and other parts of the house.
The primary function of butyl-rubber caulk is to stop leaks and cracks in the home. It is commonly used around windows, doors, and other areas of the home where seals are needed. It dries to form a flexible seal that can fit into tight places.
Also Check: What is the Difference Between Caulk & Sealant?
These are the best caulk options to consider. But if you’re not sure which one to go for, then I suggest the acrylic latex caulk. Since it has the flexibility to adapt to any changes in temperature or humidity, making it the ideal sealant for your project.
Caulking vinyl flooring seams is not a requirement, but it can help prevent water damage. If you are considering caulking your vinyl flooring seams, you should consider what you hope to accomplish with this measure.
If you want to create a waterproof barrier on the seam, then you should use silicone or latex caulk instead of acrylic caulk since they are more durable and will last longer.
However, these are just temporary fixes for your vinyl flooring. To resolve this issue from the root, you need to understand why your vinyl flooring has gaps.

Reasons Why Vinyl Flooring Develops Gaps

Moisture Issues
Moisture is one of the reasons vinyl flooring develops gaps. Water weakens the adhesive that holds vinyl to the backing, allowing it to develop gaps, warp, buckle, and sink.
Solution: You need to check for molds and mildew as they are indicators of moisture/humidity issues in the floor. If you can identify them, take action immediately to ensure the adhesive remains in top condition.
Avoid Exposure To Sunlight
Direct exposure to sunlight can heat surfaces, which can lead to excessive expansion or contraction that results in gaps.
Solution: To limit the damage to floors adjacent to windows, hang blackout and thermal curtains or apply a UV film or glass tint directly to the windows.
Not Using High-quality Adhesive
Another reason is that low-quality adhesives cannot withstand harsh weather conditions, such as extreme temperatures and heavy loads, which can cause gaps to form.
Solution: Ensure that you use an adhesive designed specifically for vinyl floors.
Not Using a Roller to Secure the Floor
You may be experiencing expanding gaps in your vinyl flooring because you didn’t use a roller after it was installed. Using a roller will guarantee the entire surface is secured, resulting in an improved finish.
Solution: As soon as you have installed flooring, roll it with a 100-pound roller to secure it to the subfloor in every area.
Leave Gaps at the End of Flooring
The most common mistake people make when laying flooring is not leaving gaps. It may seem illogical to leave gaps to avoid gaps. However, this allows the vinyl floor to naturally expand and contract as the temperature changes.
Solution: When installing the vinyl flooring, leave between a quarter-inch and a half-inch of space between it and the wall.
Wrong Installation
You may also experience many problems such as discoloration, bulking, and moisture if you install vinyl flooring incorrectly.
Solution: Before installation, read the flooring manufacturer’s installation guide carefully, and if possible, consult a professional.
Moving Heavy Objects
Moving or dragging heavy objects over vinyl flooring can also cause gaps. Additionally, use protective mats underneath the vinyl flooring with a minimum of two inches between them and the edge of your carpeted area.
Solution: To avoid damaging vinyl flooring when you drag a heavy object over it, you should use furniture sliders (or something similar) under the object’s feet.

How To Caulk Vinyl Flooring?
Step 1: Prepare the Floor by Cleaning it
Caulking a floor is a task that needs to be done with care and precision. One of the most important things to do before caulking a floor is to clean it. This will ensure that the caulking won’t have any dirt or debris in it, which could lead to problems over time.

Step 2: Apply a Mask to the Vinyl Plank’s Edges
The edges of the vinyl plank should be masked with a thick layer of painter’s tape before caulking. If you don’t mask the edges of the vinyl plank, it will be difficult to seal them and you could end up with a mess.
Step 3: Caulk the Gaps
Apply caulk between the planks and ensure you apply it under the holes and gap edges with a putty knife. Fill the adhesive under the gaps after cleaning the joint.
Step 4: Take Off the Masking Tape
When done, remove the masking tape and use a wet sponge to wipe up any adhesive that may have been dropped or smeared on the floor.
Step 5: It’s done. Let it Dry For a While.
Make sure the caulking has hardened before allowing traffic to pass through it. Follow the manufacturer’s instructions regarding caulking ventilation.
Common Mistakes to Avoid While Caulking Vinyl Floor
The installation process is not complicated, but it is important to avoid making these common mistakes.
- Using the Wrong Type of Caulk: There are different types of caulks, each designed for a specific purpose. Choosing the wrong caulk can cause problems with the joint and weaken it. So, choose your caulk wisely.
- Not Cleaning the Surface Before Caulking: Cleaning the surface before caulking can solve many problems. For example, dirty surfaces may hamper sealants from adhering properly.
- Applying Caulk Too Soon: Caulk must be applied before the floor is installed, or else it will not adhere. If your floor has already been installed, you can remove the vinyl and re-caulk it.
- Not Using Enough Caulk: You must use enough caulk so that there are no gaps between the floor and the caulk; otherwise, water can get in and ruin the flooring.
- Not Installing the Caulk at a 90-Degree Angle: If this happens, the caulk will not be able to hold up against the floor and will start to peel off.
- Using an Old Tube of Caulking: You should not use an old tube of caulk that has hardened. If yours has hardened, throw it away and buy a new tube.
FAQ: Can you Caulk Around Vinyl Flooring?
Can I use Caulk Around the Edges of LVP?
Yes, you can. The caulking will prevent water from seeping through the joint between the LVP and the substrate, and it will also provide a seal against any insects that might attempt to enter through those joints.
How do you Seal Gaps in Vinyl Flooring?
The first step in sealing gaps is to identify where they are. It can be done by looking at the joints between the tiles and at any areas where there are seams. You should also check for any water damage or other signs that indicate that there may have been a leak.
Once you know where these gaps are, you should use a high-quality sealant and spread it evenly over the area using a brush or roller.
