Horizontal gaps in laminate flooring can be fixed permanently by addressing the boards themselves, or temporarily using a filler.
Horizontal gaps, also known as separation gaps, occur when individual laminate boards pull apart from each other along their edges. This can happen due to various reasons, including:
- Temperature and humidity fluctuations: Laminate expands and contracts with changes in the environment. If the flooring wasn't installed with proper expansion gaps or acclimatized correctly, stress can cause boards to separate.
- Improper installation: If boards weren't clicked tightly together during installation, or if the subfloor wasn't flat, gaps can form over time.
- Traffic: Heavy foot traffic can sometimes cause slight movement, leading to gaps.
Addressing these gaps is important not just for aesthetics but also to prevent dirt and moisture from getting into the subfloor.
Permanent Solution: Board Removal and Replacement
According to experts, the definitive method to resolve horizontal gaps in laminate flooring is to physically rework the installation in the gapped area.
The only way to fix gaps in laminate flooring is to remove the boards and replace them with boards that fit tightly together.
This process typically involves:
- Carefully lifting the laminate planks starting from the wall nearest the gap.
- Working your way across the floor to the boards that have separated.
- Ensuring the click-lock mechanisms on the affected boards and adjacent boards are clean and undamaged.
- Reinstalling the boards, making sure each piece is properly locked into place with its neighbors, eliminating the gap.
- Reinstalling the remaining boards up to the wall.
This method is the most effective because it addresses the root cause – the physical separation of the interlocking boards – and restores the integrity of the flooring system.
Temporary Fix: Using Silicone Caulk
While removing and replacing boards is the permanent fix, a temporary solution is available for cosmetic improvement.
To fill gaps temporarily, use a silicone caulking that matches the color of the floor, applying only enough to fill the gap; wipe away any excess.
This temporary method is useful for small, isolated gaps or when a full repair is not immediately possible. It helps conceal the gap but does not re-secure the boards together.
Steps for the Temporary Caulk Fix
- Clean the gap: Ensure the gap is free of dirt, dust, and debris using a vacuum or brush.
- Select caulk: Choose a flexible silicone caulk in a color that closely matches your laminate flooring.
- Apply caulk: Cut the tip of the caulk tube to a small opening. Gently squeeze the caulk into the gap, applying only a small bead directly into the void. Avoid overfilling.
- Smooth and wipe: Immediately after applying a section, use a damp cloth or caulk tool to smooth the caulk and wipe away any excess from the surface of the laminate boards.
- Cure: Allow the caulk to dry and cure according to the manufacturer's instructions.
Remember that this is a cosmetic fix and will not prevent future movement of the boards.
Choosing the Right Fix
Deciding between removing/replacing boards and using temporary caulk depends on the severity and extent of the gaps:
- Board Removal/Replacement: Best for widespread gaps, large gaps, or when a lasting solution is desired.
- Silicone Caulk: Suitable for small, hairline gaps or as a quick cosmetic fix until a permanent repair can be made.
| Method | Permanence | Effectiveness | Difficulty Level | Primary Goal |
|---|---|---|---|---|
| Board Removal/Replacement | Permanent | High | Moderate to High | Structural & Cosmetic |
| Silicone Caulk | Temporary | Low (Structural) | Low | Cosmetic |
Ultimately, for a true fix that addresses the underlying issue of board separation, removing and properly reinstalling the affected boards is the recommended approach.
