Floating Installation Method
Bamboo flooring utilizes a scientific floating installation method that accommodates the material's physical properties and accounts for the expansion and contraction of both the concrete subfloor and the bamboo planks. The planks are interlocked via tongue-and-groove joints on all four sides without being glued to the subfloor. Expansion gaps (safety gaps) are left along the perimeter walls and covered with baseboards; this maintains the floor's aesthetic appeal while providing the necessary space for expansion and contraction, thereby preventing buckling or warping.
The floating installation method requires no joists, subflooring, glue, nails, sanding, or on-site finishing (each plank is factory-sealed on all six sides with imported UV lacquer, creating a durable, wear-resistant surface). It saves time, labor, materials, and money (installation costs are only one-third of those for traditional wood flooring) and allows for easy disassembly and reinstallation.
Pre-installation Preparation
1. Level the subfloor with cement mortar and allow it to dry completely.
2. Apply one or two coats of asphalt paint to the subfloor and allow it to dry completely.
3. Lay down 3mm-thick foam underlayment (with plastic backing); ensure it is flat, with no overlaps or wrinkles.
4. Prepare a supply of 1.2 × 1.2 cm cedar strips for use during installation.
Installing the Bamboo Flooring
1. Measure dimensions and plan material usage efficiently. All cut ends of the planks must be sealed with clear varnish to prevent moisture absorption.
2. Begin installation by placing the cedar strips (1.2 × 1.2 cm) along the base of the perimeter walls and laying the planks lengthwise. Position the first plank with its groove side against the cedar strips, then proceed to interlock the subsequent planks (tongue-to-groove), tapping them gently to ensure a tight fit. Place shorter planks-cut to fit the room's length-against the walls at the ends of the rows. Stagger the transverse joints of the bamboo planks.
3. Once the entire floor is installed, remove the cedar strips from the perimeter.
4. Install baseboards along the perimeter walls to cover the expansion gaps. Secure the baseboards to the wall using wood screws or bamboo pegs; touch up the screw or peg heads with paint (or varnish) that matches the color. Finally, finish the top edge of the baseboard with a decorative wood molding of the same thickness.
Important Note:
Do not fit bamboo flooring planks too tightly together; allow for natural expansion to prevent compression damage. Do not apply glue to the underside of the bamboo flooring where it contacts the subfloor. Installation quality directly affects the overall appearance and performance of the flooring; professional installation by an experienced carpenter is recommended.】
Fixed Installation Method
Ensure the subfloor is level, thoroughly dry, and clean. Lay a layer of roofing felt or moisture-proof paper over the subfloor, then secure standard wooden battens (joists) to the concrete; a spacing of 30 cm between joists is ideal. Lay and secure 1 cm thick plywood over the joists, then install the bamboo flooring onto the plywood, fastening the tongue-and-groove joints with small nails. Seal the cut ends of the bamboo flooring with clear oil or sealer to prevent moisture absorption. Leave a 1–1.5 cm expansion gap around the perimeter of the floor before installing the baseboards.
Precautions
1. Install the flooring first, followed by the baseboards.
2. Use 1.5 cm thick bamboo flooring material for the baseboards; ensure the expansion gap remains free of debris to allow for natural floor expansion and contraction.
3. Apply proper waterproofing and isolation treatments at the junctions where the flooring meets bathrooms, kitchens, and balconies.
4. Do not walk on the floor for 12 hours after installation.
5. Do not wash the floor with running water; clean only with a wrung-out mop or cloth.
6. Wipe up any spilled water immediately.
7. Close doors and windows when leaving the premises to prevent rain from wetting and damaging the floor.
8. Placing a doormat at the entrance is recommended to minimize abrasion caused by sand, dirt, or mud (this step is unnecessary if it is customary to remove shoes).
9. Wax the floor periodically as needed.
