Laying new laminate flooring over existing laminate is a common question among DIY enthusiasts. The appeal is undeniable – it offers the potential to transform the look of a room without the inconvenience and dust of a full removal. However, the feasibility of this endeavor depends on several crucial factors. This guide will explore the pros and cons, the necessary steps, and the potential pitfalls of layering laminate over existing laminate. We’ll provide you with the information you need to make an informed decision for your home improvement project.

The Pros and Cons of Laying Laminate Over Existing Laminate

Before you grab your tools and start ripping up the old flooring, let’s weigh the advantages and disadvantages of laying laminate over existing laminate.

The Pros

  • Cost Savings: Replacing existing laminate with new flooring can be a significant expense. Layering laminate over existing flooring could potentially save you a lot of money, especially if you’re doing the work yourself.
  • Faster Installation: Laying laminate over existing flooring can be significantly faster than removing and replacing it. This can be a great advantage if you’re looking for a quick and easy renovation.
  • Less Mess: Layering new laminate over existing flooring can create significantly less dust and debris compared to removing the old floors. The less messy installation can make a big difference, especially if you live in a smaller space or have furniture you need to move.
  • Potential for Adding Insulation: In some cases, laying new laminate over existing laminate can offer an opportunity to add extra insulation underneath to your flooring. However, it’s important to consider the extra height it might add to your floors and if that would hinder any door clearances.

The Cons

  • Potential for Uneven Surfaces: If the existing laminate flooring isn’t completely level, the new laminate may not lay flat. Unevenness could lead to buckling, gaps, and unevenness, compromising the aesthetic appeal and potentially causing safety hazards.
  • Increased Floor Height: Laying new laminate over existing laminate will add thickness to your floor. This can impact things like door clearance, furniture, and appliance fit.
  • Potential for Sound Transmission: Depending on the existing laminate and the new laminate, you might notice an increase in sound transmission. This can be a concern in apartments or homes with multiple floors where noise reduction is important.
  • Limited Underlayment Options: Laying new laminate over existing laminate may limit your choice of underlayment. Ensure the underlayment is compatible with both the existing laminate and the new laminate.
  • Uneven Wear and Tear: Layering laminate over existing laminate can lead to uneven wear and tear since you’re essentially adding extra weight to a pre-existing structure.

When It’s a Good Idea to Lay Laminate Over Existing Laminate

While there are advantages and disadvantages to consider, layering laminate over existing laminate can be a viable solution in certain situations:

  • Minor Unevenness: If the existing laminate has minimal unevenness, especially if it’s less than 1/4 inch, layering new laminate might be possible.
  • Solid Subfloor: If the subfloor beneath the existing laminate is in good condition – solid and stable – then adding a layer of laminate on top can be a good option.
  • Cosmetic Update: If your primary goal is to refresh the look of your room with a new color or style of laminate, layering can be an efficient solution.

When You Should Not Lay Laminate Over Existing Laminate

While it can be tempting to take the easy route, layering new laminate over existing laminate isn’t always the best solution. Here are some scenarios where it’s best to avoid this approach:

  • Significant Unevenness: If the existing laminate flooring has significant unevenness, or dips and bumps greater than 1/4 inch, layering new laminate is likely to result in unevenness and potential issues with movement and stability.
  • Poor Subfloor Condition: If the subfloor beneath the existing laminate is damaged, warped, or weakened, then layering new laminate will only amplify the problems. It’s crucial to address the subfloor issues before considering flooring.
  • Structural Concerns: If the existing floor is showing signs of structural movement – cracking, bowing, or shifting – layering new laminate won’t adequately address the underlying problem.

Steps to Lay Laminate Over Existing Laminate

If, after careful consideration, you decide to lay new laminate flooring over existing laminate, it’s crucial to take the correct steps:

  • Prepare the Subfloor: Ensure the subfloor beneath the existing laminate is solid, flat, and even. Repair any cracks, dips, or unevenness in the subfloor.
  • Evaluate Existing Flooring: Assess the existing laminate flooring for any loose boards or loose areas. If necessary, glue or nail down these areas.
  • Moisture Barrier: Apply a moisture barrier, such as a thick plastic sheeting, to the existing laminate floor. This will protect the new laminate from moisture damage.
  • Underlayment: Install an underlayment on top of the moisture barrier. The underlayment will help cushion the new laminate and provide insulation.
  • Lay the New Laminate: Install the new laminate flooring according to the manufacturer’s instructions. Make sure you’re using the proper tools and techniques for a seamless installation.
  • Finish the Edges: Trim and install the edges of your new laminate flooring to ensure a professional-looking finish.

Important Considerations

  • The Height Factor: Always consider how layering laminate over existing laminate will change the height of your floor and any potential impacts on doorways, appliances, or furniture.
  • Warranty: Consult with the manufacturer of your new laminate to ensure that installing a second layer of laminate flooring won’t void the warranty.

Alternatives to Laying Laminate Over Existing Laminate

If layering new laminate over existing laminate isn’t feasible or you’re hesitant about the potential problems, consider these alternative options:

  • Sand and refinish: If your existing laminate is in good condition, sanding and refinishing it can effectively give it a fresh look. However, this is only an option if the laminate can be refinished.
  • Vinyl Plank Flooring: Vinyl plank flooring is a water-resistant flooring option that can be easily installed over existing laminate. It tends to be more forgiving than laminate with uneven surfaces, and it comes in various styles to match your décor.
  • Engineered hardwood flooring: For a more luxurious look, engineered hardwood flooring can be installed over existing laminate. Engineered hardwood is more stable than traditional hardwood, making it suitable for layering.
