- Some laminate floors might have an underlayment beneath them. It is essential to check if the underlayment is suitable for a second layer. If it is not, removing the initial layer becomes necessary.
Preparing the Existing Laminate Flooring for Installation
Assuming the existing laminate flooring is in good condition, level, and free from moisture issues, here are the steps to prepare it for the installation:
1. Clean the surface thoroughly:
- Remove any dust, debris, or dirt from the existing laminate flooring. This will ensure a clean surface for the new laminate to adhere to.
2. Level any uneven areas:
- It is crucial to have a level surface for the new flooring installation. If there are any uneven areas, use a self-leveling compound to smooth them out.
3. Sand or degloss the existing laminate:
- To improve the bonding between the old and new laminate layers, sand the surface of the existing laminate or degloss it using a liquid deglosser. This step will help the new laminate adhere better.
Installing the New Laminate Flooring
Once the existing laminate is prepared, you can move on to the installation of the new laminate layer. Follow these steps for a successful installation:
1. Choose an appropriate new laminate flooring:
- Select a laminate flooring product that is compatible with the existing laminate and meets your aesthetic preferences.
2. Acclimate the new laminate flooring:
- Before installing, allow the new laminate to acclimate to the room’s temperature and humidity levels as per the manufacturer’s instructions. This step prevents future issues such as expansion or contraction of the new flooring.
3. Install a vapor barrier:
- Lay down a vapor barrier over the existing laminate flooring. This additional layer provides moisture protection and prevents any potential moisture damage.
4. Begin the installation process:
- Follow the manufacturer’s instructions for laying the new laminate flooring. Start from one side of the room, ensuring proper alignment and using spacers to maintain the necessary expansion gap.
5. Trim and finish the installation:
- Once the laminate is installed, trim excess flooring, install baseboards or molding, and make any necessary adjustments for a polished and finished look.
While it is possible to install new laminate flooring over existing laminate, certain conditions must be met. Assessing the condition of the existing flooring, proper preparation, and choosing the appropriate laminate product are all crucial factors to consider. Following the necessary steps and manufacturer guidelines will help ensure a successful and long-lasting installation. However, if the existing laminate flooring is damaged or there are concerns with the subfloor, it is generally recommended to remove the old laminate before installing the new one.
