Reasons Why Vinyl Flooring Develops Gaps

Can you Caulk Around Vinyl Flooring

1. 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 on the floor.

2. 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.

3. 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.

4. 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.

5. 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.

6. 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.

7. 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.
  • 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.
