The separate joints of our laminate flooring or laminate flooring are one of the most common problems in this type of installation. The logical thing is that it should be at most one or two meetings. If many were separated, it is possible that the problem is much greater: a bad installation (a critical failure), poor quality flooring and a poor anchoring system.

When I speak of incorrect installation, we do not necessarily mean that the parts have been fitted incorrectly. It may also be due to irregularities in the subsoil that have not been resolved or the climatic conditions are not ideal (many fluctuations in temperature and humidity).

The real problem with open joints in laminate floors is not aesthetic. Once opened, deterioration accelerates. Particles are introduced, the edges are chipped and mainly water starts to penetrate. You have to come up with a solution as soon as possible. Fortunately, it’s not too complicated to do that

Why does the laminate floor open?

The laminate floor is mainly wooden. And this naturally expands or contracts in the face of environmental changes. With these fluctuations, small gaps can occur between some pieces of laminate flooring.

The importance of the click system on laminate floors

The purpose of current click or anchor systems is not only to facilitate installation, but also to prevent the joints from opening with the natural movement of the laminate floor.

If the type of click is bad, the result is a weak union and what happens happens. Other factors that can affect adherence are the thickness of the board and the density of the board. That is, the thicker and higher the density, the greater the resistance.

These are some of the factors that go unnoticed by many laminate flooring buyers who only look at the design and price and, at most, the AC rating.

How to repair the gap in the laminate floor?

Depending on the size of the problem, there are several solutions for joining laminate or laminate flooring joints.

It’s something specific

If it’s one or two, we can use some tricks to repair open or separate joints. The idea is very simple. Fix something that we can achieve in one direction or another in a clapboard in a timely manner and without leaving any marks.

repair laminate floor joints


Option 1: A piece of wood, strong double-sided tape and a hammer.

option 2: A suction cup, like those used by masons for large ceramic pieces, and a hammer, preferably rubber, to avoid damaging the suction cup.

We fix the piece of wood or the suction cup on the clapboard and tap in the direction in which we want to join the pieces.

The problem with this method is that, when joining a joint, we can separate another on the same line. It is something that must be contemplated and anticipated to decide where we will start to repair together. The idea is to have the least number of joints up to the wall.

The problem is big and there are many separate cards

If there are many meetings open, it is best to attack him head on.

  • Separate the baseboard from the wall. You can damage the wall and even the skirting to do this (this is something that is often overlooked). Do not start removing the baseboards like crazy, look where the joints have opened and determine where you are going to hit to put the pieces together.
  • Use the laminate floor installation lever to put the pieces back together. Although the advantage of doing this is that new joints will not be opened between the pieces, it will be necessary to check the expansion joints with the walls. Minimum and maximum distances must be respected, which in this case are defined by the thickness of the baseboard, which is the element that must hide it.
  • Replace the baseboard. You may need to reuse caulking and even some paint to make it look good again.

Note: If it turns out that the problem is recurring, we can use carpenter’s glue. We will impregnate the joint before joining it and then, once joined, we will clean the surface.
