Installation of Solid Wood Flooring

1. Ground Preparation:
   • Thoroughly clean the ground to ensure it is free of dust, sand particles, and other debris.
   • Check the flatness of the ground, and if there are areas with unevenness exceeding 3mm, leveling treatment is required.
   • Measure the ground moisture content to ensure it is dry to prevent the floor from warping due to moisture.
2. Determine the Laying Direction:
   • Based on the room orientation and lighting conditions, determine the direction of floor laying. Typically, for south-facing rooms, the floor should be laid vertically towards the direction of sunlight.
3. Preparation of Auxiliary Materials:
   • Prepare auxiliary materials such as joists, moisture-proof mats, and floor-specific nails according to the floor laying method.

1. Installing Joists:
   • Joists should be made of dry, moth-proof, and straight wood, usually with specifications of 3×5 cm or 4×6.25 cm.
   • Joists need to be planed on all four sides and dried to ensure their moisture content is moderate, preventing the floor from warping.
   • Use special joist nails to fix the joists to the ground, ensuring they are level and securely fixed.
2. Laying Moisture-Proof Mats:
   • Lay 1.5mm-thick moisture-proof mats on the joists to isolate ground moisture and protect the floor from dampness.
3. Pre-Laying the Floor:
   • Pre-lay the floor to check for color differences and texture matching, avoiding large patterns or excessive contrast.
   • When pre-laying, the length of the floor should align with the direction of the entrance to ensure a good visual effect.
4. Official Laying:
   • Use floor-specific nails to fix the floor to the joists at a 45-degree angle. Note that nails should not be driven directly into the floor; instead, pre-drill holes first.
   • When laying, leave an expansion gap of 8-10mm between the floor and the wall to accommodate thermal expansion and contraction.
5. Installing Baseboards:
   • After laying the floor, install baseboards to cover the expansion gap and enhance the indoor aesthetics.
6. Installing Trim Strips:
   • Use trim strips or edging strips at the connections between the floor and thresholds, tiles, etc., to ensure a beautiful and sealed appearance.

1. Avoid Cross-Operations:
   • Avoid cross-operations with other renovation projects when installing the floor to prevent damage to the floor.
2. Keep the Ground Dry:
   • Ensure the ground is dry before installation to prevent the floor from warping due to moisture.
3. Regular Maintenance:
   • Regularly maintain the floor, such as waxing, after installation to extend its lifespan.
4. Professional Installation:
   • It is recommended to have solid wood flooring installed by professionals to ensure installation quality and aesthetics.
