The quality of installation for multi-layer solid wood flooring directly impacts its performance and longevity. At Macro-Resistant Flooring, we're here to guide you through three commonly used and effective installation methods for multi-layer solid wood flooring. Depending on your specific situation, you can choose the most suitable method for your home.
**1. Direct Mount Installation Method (Suitable for both underfloor heating and non-underfloor heating systems):**
This method involves using a moisture-proof cloth beneath the floor.
- **Application Scope:** Ideal for floors with a flatness tolerance of ±2mm.
- **Installation Steps:**
(1) After preparing the subfloor, lay a moisture-proof cloth across the entire surface to provide insulation, sound reduction, and moisture control. For underfloor heating systems, the cushion material should not be too thick to ensure efficient heat transfer.
(2) Place the multi-layer solid wood flooring directly on top of the moisture-proof cloth.
**2. Traditional Floating Installation Method (Suitable for non-underfloor heating systems):**
This approach uses plywood, moisture-proof cloth, and the multi-layer solid wood flooring.
- **Application Scope:** Best suited for floors with a flatness of no more than 5mm, especially for second-floor installations.
- **Installation Steps:**
(1) Clean the subfloor thoroughly. Cut the plywood into pieces no larger than 600 x 600mm, leaving a 5–10mm gap between each piece.
(2) Lay a moisture-proof or flame-retardant foam layer on the plywood. Ensure that the moisture-proof cloth extends 8–10mm above the floor edge, and avoid bonding the plywood directly to the moisture-proof cloth.
(3) Install the multi-layer solid wood flooring on top of the moisture-proof cloth without adhering it. Use 45-degree angled nails to secure the floorboards to the subfloor.
**3. Elevated Installation Method (Suitable for non-underfloor heating systems):**
This method includes a dedicated wooden frame, padded splints, moisture-proof cloth, and the flooring itself.
- **Application Scope:** Suitable for floors with a flatness of up to 5mm and for second-floor applications.
- **Installation Steps:**
(1) Prepare special wooden keels with spacing no more than 350mm apart, ensuring the surface is level.
(2) Apply waterproof adhesive to the wooden keels, then place 12mm-thick plywood over them. Cut the plywood into pieces no larger than 600 x 600mm, leaving 5–10mm gaps between each. Secure the plywood to the keels using an air gun and headless nails.
(3) Lay a moisture-proof cloth over the plywood, then install the multi-layer solid wood flooring on top. Fix the flooring with 45-degree angled nails without using glue.
It’s important to note that most multi-layer solid wood flooring installations are carried out by professional installers. While this guide provides a general overview, it's always best to hire experienced and skilled professionals to ensure a long-lasting and beautiful finish. At Macro-Resistant Flooring, we strongly recommend working with qualified installers who understand the nuances of proper installation.
