How To Fix Gaps In Laminate Flooring

Laminate flooring, prized for its affordability and durability, may encounter issues like gaps over time, affecting its visual appeal and functionality. This detailed guide delves into effective strategies to fix gaps in laminate flooring providing insights for a seamless and enduring solution.

Commence the gap-fixing process by meticulously clearing away any dirt or debris lodged in the gaps. Utilize a vacuum or a soft brush to ensure a clean surface, preparing it for the subsequent repair steps. Equally important is maintaining optimal room humidity, preventing gaps caused by the natural expansion or contraction of laminate.

Using Wood Filler

Once the laminate flooring is meticulously cleaned and prepared, the next critical step in addressing gaps involves the strategic application of wood filler. This step not only serves a functional purpose in closing gaps but also plays a crucial role in restoring the visual integrity of the flooring.

  1. Selecting the Right Wood Filler: Begin by choosing a high-quality wood filler that closely matches the color and texture of your laminate flooring. This ensures a seamless blend, making the repaired areas nearly indistinguishable from the rest of the floor. Wood fillers are typically available in various shades, allowing you to find an option that complements your specific laminate design.
  2. Application Process: With the chosen wood filler in hand, use a putty knife to carefully apply the filler into the gaps. Ensure that the gaps are adequately filled, and the excess filler is smoothly spread over the surface. The putty knife facilitates a precise application, helping create a uniform and well-integrated repair.
  3. Smoothing the Surface: After applying the wood filler, it’s crucial to focus on achieving a smooth surface. Gently run the putty knife over the filled gaps to level the filler with the surrounding laminate. This step is essential for not only enhancing the visual appeal but also ensuring a seamless transition between the repaired areas and the rest of the floor.
  4. Drying Time: Allow the wood filler sufficient time to dry completely. The drying time may vary based on the specific product used, so refer to the manufacturer’s instructions for guidance. Patience during this phase is crucial to prevent any premature damage to the repaired areas.
  5. Finishing Touches: Once the wood filler has dried, inspect the repaired areas for any imperfections. If needed, lightly sand the filled gaps to achieve a flawless finish. This additional step contributes to the overall smoothness and uniformity of the repaired laminate flooring.

Adjusting Laminate Planks

If the gaps persist even after applying wood filler, the next step involves adjusting the laminate planks to ensure a snug fit and eliminate any remaining spaces. This process requires a gentle touch and precise alignment to seamlessly bring the planks back into cohesion.

  1. Identifying Problematic Areas: Begin by identifying the specific areas where the gaps persist. Inspect the flooring closely, paying attention to any irregularities or misalignments in the laminate planks. Pinpointing the problematic spots will guide you in targeting the adjustments more effectively.
  2. Gentle Tapping with a Rubber Mallet: Utilize a rubber mallet to gently tap the laminate planks into position. Position the mallet at the edge of the plank and apply controlled force to encourage it to slide snugly against its neighboring plank. This technique is particularly effective in cases where minor adjustments are needed to close gaps.
  3. Ensuring Proper Alignment: As you tap the planks, pay careful attention to their alignment. Ensure that each plank sits flush against the adjacent one, leaving no room for gaps to reappear. A gradual and measured approach is key to avoiding damage to the laminate surface while achieving the desired alignment.
  4. Filling Larger Gaps: For larger gaps that persist despite adjustments, consider using additional wood filler to fill the spaces between the planks. Apply the wood filler with the putty knife, following the same principles outlined in the wood filler application step. This secondary application can provide extra support in closing more substantial gaps.
  5. Visual Inspection: After making adjustments, conduct a thorough visual inspection of the entire laminate floor. Ensure that the gaps have been effectively closed, and the overall appearance is cohesive. Walk across the floor to check for any creaking or movement, which could indicate lingering issues.
  6. Reassessing and Fine-Tuning: Reassess the areas that were adjusted after some time, as laminate flooring can settle. Fine-tune the adjustments if necessary, addressing any gaps that may reappear over time. This proactive approach ensures the continued integrity of the laminate flooring.

Transition Strips

Enhance both visual appeal and gap concealment by installing transition strips in doorways, especially between rooms with varying dimensions. Opt for transition strips that complement the laminate flooring, contributing to a cohesive and polished look.

Subfloor Inspection and Maintenance

Address persistent gaps by inspecting the subfloor for irregularities that may be exacerbating the issue. Uneven subfloors can lead to an uneven laminate surface, causing gaps to manifest. Promptly rectify any subfloor concerns to establish a stable foundation for your laminate flooring.

Preventive Measures

Ensure the longevity of your laminate flooring by adopting preventive measures. Regular maintenance, such as prompt spill cleanup and periodic inspections, is crucial. Proactive care will not only address existing issues but also prevent potential complications, sustaining the aesthetic appeal and functionality of your laminate flooring over time.


In conclusion, repairing gaps in laminate flooring is a manageable task when approached systematically. By following the comprehensive steps outlined in this guide, you can effectively remedy existing gaps and implement preventive measures, ensuring your laminate flooring remains both visually pleasing and functional for an extended period.
