Laminate Flooring Pulling Apart

Laminate flooring coming apart is a common problem in homes where moisture, uneven subfloors, or poor-quality flooring products are present. Many homeowners notice gaps forming between planks or locking systems separating after daily use. In most cases, the flooring itself is not the main issue. Instead, the problem usually starts underneath the floor or from excessive moisture exposure over time.

If you want to avoid laminate flooring coming apart, it is important to choose the right product from the start. Water-resistant laminate flooring with a thickness of 8mm or higher usually performs much better than thinner 6mm or 7mm products. Thicker laminate flooring has a stronger locking system, better stability, and improved durability for long-term use.

Why laminate flooring comes apart

One of the biggest causes of laminate flooring coming apart is excessive moisture. Water can enter through spills, leaks, damp subfloors, or high moisture levels underneath the flooring. Over time, the boards start to swell slightly, placing pressure on the locking system. Once the locking joints weaken, gaps may start to appear between the planks.

This problem is far more common with low-quality or thin laminate flooring. Many 6mm and 7mm laminate floors use smaller locking systems that cannot handle movement and pressure as well as thicker boards. An 8mm or 12mm laminate floor normally has a much thicker and stronger locking profile, making it more stable during daily use.

Modern water-resistant laminate flooring can also help reduce the risk of swelling and joint separation when small spills happen. However, even water-resistant flooring still needs proper installation and moisture control.

Uneven subfloors can cause laminate flooring to pull apart

An uneven subfloor is another major reason laminate flooring starts separating over time. Many homeowners do not realise how important floor preparation is before installation begins. If the subfloor has dips, high spots, or movement, the laminate flooring flexes while people walk on it every day.

As the floor settles during normal use, thinner laminate flooring slowly starts moulding to the shape of the uneven subfloor underneath. This movement places stress on the locking system and eventually causes the planks to pull apart. The thinner the flooring, the easier this usually happens.

That is why professional installers often recommend screeding uneven areas before installation. A level and stable subfloor helps prevent movement, improves the lifespan of the flooring, and reduces the risk of joint separation later on.

Why thicker laminate flooring performs better

Choosing a thicker laminate floor can make a big difference in long-term performance. An 8mm or 12mm laminate floor normally feels more stable underfoot and uses a stronger locking system than thinner products. The boards resist movement better and can handle small subfloor imperfections more effectively.

Many premium laminate flooring ranges also include improved water resistance, stronger core boards, and more durable click systems. These features help reduce the chance of the flooring pulling apart over time.

How to prevent laminate flooring from separating

The best way to prevent laminate flooring coming apart is to combine good-quality flooring with proper installation. Always check for moisture problems before installation starts. Uneven subfloors should be levelled correctly, and a suitable underlay should be used to support the flooring system properly.

It is also important to avoid excessive water exposure after installation. Clean spills quickly, maintain good ventilation, and make sure leaks are repaired as soon as possible.

At Laminate Floor World, we recommend using quality laminate flooring with strong locking systems and proper floor preparation to help prevent common flooring problems in the future.
