How to Fix Gaps in Vinyl Plank Flooring? (5 Easy Steps)
Over time, vinyl plank flooring shifts and leaves gaps between them.
Gaps on the vinyl plank floor are critical and pose problems on the surface, like peeling, chipping, cracking, scratches, and crumbling at the edges.
Therefore, it would be wise to fix the gaps to maintain the aesthetic and elegance of the floor and its lifetime. Vinyl plank floors are budget-friendly, durable, and resistant to elements such as humidity, mold, and mildew, thus worthy of fixing the gaps.
Below are some methods you may employ to fix gaps in vinyl plank flooring, depending on flooring installation.
Types of Vinyl Plank Floors
Vinyl plank floor comes in three main types. They include
- Glue-down vinyl plank floor: This type of vinyl flooring is glued down with glue to hold the vinyl plank floor in place.
- Click-in vinyl plank floor: Click-in vinyl plank comes with pieces designed with tongue and groove as the interlocking system to fit them together. After laying the planks on the floor, click them together beside each other to install. But ensure you have flattened the surface before installing to achieve maximum evenness.
- Loose-lay: With this type of vinyl floor, nothing holds them in a place, neither by glue nor clipping. Instead, they are loosely aligned, and they stay in place through the backing of friction.
Prerequisites Before You Start Fixing Gaps on Vinyl Flooring
- Mop the floor to get rid of debris and dirt build-up in the gaps, or you may vacuum for the best outcome.
- After moping, you should wait for about 24 hours to allow the floor to dry for the adhesive to seal the gap effectively. Use your finger to confirm or check if the gap is dry as you desire.
How to Fix the Gaps on Glued or Clicked-In Vinyl Flooring?
If you want to fix glued or clicked-in vinyl flooring gaps, we recommend using the Caulking method.
Caulking is the best because it helps fill and solidify the gaps and is water-resistant.Â
Select a caulk made from latex, silicone, or acrylic. All these are effective, but silicone is the most preferred because it can withstand high-temperature climates and harmful conditions.
But acrylic would serve that purpose if you want caulking that can strengthen and extend the life of floorboards.
For minimal scent and desirable-size expansion, you should opt for latex. Lastly, use a caulk that matches the color palette of your planks best while wet and dry because some caulk changes drastically once dry.

Step 1: Clean the Floor
Mop/vacuum and dry the floor as suggested from the ABOVE.
Step 2: Mask the Edges of Vinyl Planks
Mask the edges of planks where you intend to fix the gap using masking tape to prevent the caulk from smearing and sticking plank top surface.
Step 3: Add Some Caulking in the Gaps
Add some caulking to the gaps between the planks and ensure you apply under the holes and gap edges using a putty knife. Fill the adhesive under the gaps using a putty knife and remove excess glue off the floor after cleaning the joint.
Step 4: Remove the masking tape
Once done, remove the masking tape and use a wet sponge to remove the adhesive that might have accidentally dropped or smeared on the floor.
Step 5: It’s Done. Give Sometimes to Dry
Allow the caulking to breathe according to the manufacturer’s instructions, and confirm it is hardened before you allow traffic on it.
Alternatives ways to Fix the Gaps on Glued or Clicked-In Vinyl Flooring
Aside from Caulking, you may also use other alternatives to fix glued and click-in vinyl flooring gaps. They include;
Use Epoxy Resin
Epoxy resin is a water-resistant adhesive like silicone.
However, epoxy resin is ideal, while the gaps are still relatively small. Administer a small amount of the adhesive under each opening and hole, but ensure you have covered the top edges of the vinyl like in the caulking method.
Note: Epoxy resin is toxic to inhale; therefore, ensure you wear a face mask and that the space /room is well-ventilated to avoid suffocation.
Inserting small parts of Wood or Plastic
This method is ideal for all types of vinyl flooring, especially when the gaps are wider and deeper because they necessitate drastic measures. Take small wood or plastic parts, place them under the gaps, and then use glue to bond and waterproof the vinyl flooring.
How to Fix Gaps in Loose-Lay Vinyl Plank Flooring?
With loose-lay vinyl plank flooring, fixing the gaps between the planks is a straightforward process that can be achieved within a few minutes. There are various methods you may employ. They include;
Use a Suction Cup and a Rubber Mallet
First, mop or vacuum around the plank you intend to fix. Add some caulk or wood putty to the gap, and then attach a suction cup.
After attaching the suction cup, hit it with a rubber mallet to close the gaps and bring the planks back to their original position. Once done, remove the excess caulk or wood putty using a clean damp cloth or wet finger.
Using A Scrap Piece And Double-Sided Tape
If you feel that a suction cup is unfriendly to the texture of your vinyl floor, you may use the double-sided tape method to fix the gaps.
Attach a scrap piece of wood to a double-sided tape, peel the other side of the tape and then attach the scrap to the vinyl plank that needs fixing.
After attaching, use a rubber mallet and hit gently towards the gap you want to close. While using this method will yield more gaps nearby. Therefore, it’s advisable to keep on closing the gaps until the gap behind the baseboard is hidden.
How to Prevent Vinyl Plank from Developing Gaps?

Gaps on the vinyl plank floor are brought due to a change in temperature and humidity, moisture issues, high traffic, and moving heavy objects or furniture across and around the flooring.Â
Nonetheless, not allowing for a perimeter for natural expansion towards the wall while installing vinyl flooring may also buckle, especially with loose-lay vinyl type. Below are some precautions to prevent vinyl plank flooring from developing gaps. They include;
Avoid Exposure To Sunlight
You may either hang a blackout/thermal curtain or apply a UV film or glass tint directly to the windows to minimize heat and UV transfer into the room and limit damage to floors adjacent to the windows. Besides, the indoor and outdoor temperature fluctuation should not be huge as the latter can impact expansion and contraction.

Use High-quality Adhesive
When installing a glue-down vinyl floor, ensure you use a top-quality adhesive. Plus, you apply it properly according to the manufacturer’s guide to achieve the best result.
Use a Roller to Secure the Floor
After installing the flooring, you should roll the floor with a 100-pound roller to secure the flooring and adhesive to the subfloor in every area. Nonetheless, it also prevents buckling of the flooring down the line.
Moisture Issues
Look for molds and mildew as they indicate moisture/humidity issues in the flooring. If you come across them, fix the problem immediately to maintain the adhesive in perfect condition before it becomes weaker.
