How to Repair Laminate Flooring That Is Separating [4 Simple Steps]

Laminate flooring has been a popular choice for a long time.

But when those floors start to separate, you have to repair them.

And if you don’t know how to, you might ask:

How to repair laminate flooring that is separating? 

The first objective is to figure out which board was the first to move. Clean out the gaps and take off the baseboard. Leave a small expansion gap though. Then apply the wood glue in places where the boards have come off. After that, knock them all back in place. 

This is only a summary of the entire procedure. To get more insights follow my lead!

Let’s scroll down and read the article!

Why Does Laminate Flooring Separate? 

Laminate flooring is sometimes called the floating wood floor. It’s one of the best floorings that goes with a lot of houses. 

Now, before we start repairing, I think it’s important that you know the cause behind separating. There are quite a few reasons, let’s go over them one at a time. 

The first reason is the high humidity level. Laminating floors swell and shrink as a result of the hot and humid weather. This causes gaps to occur. 

Laminating flooring might also separate when the temperature is very low. If your room temperature drops below 60 degrees Fahrenheit, they can separate. 

The last reason for separation might occur for specific cases. The laminate floorboards that use a click-lock system can separate. 

Another possibility is that the latch is broken or that the installation is bad. Poor installation can cause the glue to get in the interlock system. Which will cause the latch to not lock. 

The final reason is an uneven subfloor. You need to put subfloors underneath laminate flooring. If those subfloors are uneven, the laminate flooring will separate. 

Step-By-Step Process of Fixing Laminate Flooring

You might find some similarities in this process with fixing gaps in the tub and floor tile. The only exception is the adhesive used. 

You should be aware of the required equipment before we begin the step-by-step procedure.

Let’s look at the type of equipment you’ll be needing-

Necessary Equipment

Here’s a list of all the tools and equipment you’ll need-

  • Dust cleaner 
  • Hammer
  • Mallet
  • Chisel 
  • Crowbar
  • Improvisation tool (could be a toothpick or a matchstick etc.)
  • Wood Glue
  • Floor Gap Fixer 

These are just about everything that you’ll need to repair your separating laminate flooring. Without any further ado, let’s go right into the procedure immediately- 

Step 1: Locate The First Gap

Before all the pieces start separating, there’s always one or two boards that start it. Your first task is to locate the board.

It’s not that difficult to find out. Once you start to see the gaps, you can trail it back to the first one. 

You’ll see that dust has accumulated between the gaps. Use the dust cleaner to clean them out. You don’t want any dust to be there when you’re repairing the floor. 

Once you figure out the beginning, you can start repairing the floor.

Step 2: Removing The Baseboard

Removing the baseboard is quite easy. Take up the crowbar and the hammer or mallet and start working on it. Just be gentle with the boards so you don’t damage them. 

Before you start putting them back on, remember to leave a small expansion gap. This gap will be between the boards and the wall. The gap can be the width of a coin. 

This expansion gap is security for when your floors expand again. They’re bound to do so in the winter. 

Step 3: Application of The Wood Glue

Once you’re done taking off the boards, it’s time to apply wood glue. Here’s a list of some of the best wood glues-

Product 2

Use these products to get the best result!

Put small drops of the glue in places where the boards have come. You can use the improvisation tool to put them in place. 

The chances of them coming off from the same area is pretty high. Using the wood glue will make sure it doesn’t move from its place anytime soon. 

Also, it’s better if you don’t use any other type of glue. Wood glue dries and clears some time after application. Other glues expand in place. Which can be problematic. 

Step 4: Knocking The Planks Back in Place

Unless all the boards have been put in place, you’ll have to knock them back in place. 

Fit the floor gap fixer on boards that have to be put in place. After that, use the hammer or mallet to reinstall them. You can even caulk the baseboards if you want to. 

Once you’re done, you should let the floor be for at least 24 hours. It’ll dry in the meantime. 

Follow these steps thoroughly and you won’t face any problems. 


Question: Do you glue down laminate boards when you get them at first?

Answer: When you get laminate boards at first you don’t glue them down. There’s this snap-together fastening system that is used. If you get gaps more often, you should glue them down.

Question: To acclimate laminate boards to room temperature, how long should they be kept?

Answer: It’s wise to store laminate boards for at least 48 hours in the room. The boards will get accustomed to the temperature and humidity of the room. 

Question: Can bubbled laminate flooring be fixed?

Answer: Laminate floors bubble up due to high humidity in the atmosphere. Poke the small ones with a pin. And push down the big ones by filling them up with glue. 


This is everything on how to repair laminate flooring that is separating. Follow the procedure properly and there shouldn’t be any problem. 

After you’ve finished, leave the glue to cure for at least 24 hours.

Facing a different type of problem? It’s better if you call for a professional. 

Good luck!
