3. Step 3: Install finishing accessories – After completing the installation of the floor panels, proceed to install the finishing accessories such as:

• T-brace: Connect floors or use to divide areas with width and length >7m.
• F-shaped bracket: Installed at the end of the floor and covers any gaps in the floor.
• Basement wool: Cover expansion gap between floor and wall, creating aesthetics.

4. Step 4: Quality check and finishing cleaning – After completing the installation, it is necessary to perform a 3-step quality control process:

• Check for stability: Walk over entire floor area to detect unstable, creaking or shaking areas.
• Check aesthetics: Inspect the entire floor surface to ensure there are no unusual gaps, joints are even and accessories are installed correctly.
