Thermo Bamboo Maintenance Guide

For outdoor decking and cladding

Why Maintenance Matters

Thermo Bamboo outdoor boards face daily exposure to natural elements like sunlight, rain, soil, and windblown dust. Over time, this can lead to fading, soiling, and surface wear. To preserve beauty and longevity, regular maintenance is essential.

With proper care, your boards can restore up to 80–90% of their original appearance, while reinforcing their weather resistance and extending their lifespan.

Important for Poolside Decking:
Around swimming pools, if the boards are left unmaintained for long periods, the surface can become rough. Walking barefoot may cause discomfort or abrasion to the skin. Regular maintenance is strongly recommended in these areas.

Maintenance Overview

First Treatment: You may oil the decking boards immediately after installation. The ideal first maintenance is around 3–6 months after installation.
Annual Routine: It is recommended to perform maintenance at least once a year for outddor decking using WOCA oil (or another water-based outdoor oil) together with a silicon-carbide broom or pad.
More Frequent Care: Depending on local climate and usage (e.g., heavy traffic or poolside), cleaning and oiling more than once per year may be required.
Cladding & Panels: Typically require less care—once annually or as needed.
Daily Upkeep: Keep the surface free of dirt with regular sweeping.

Best Practices & Tips

Without oiling, the surface will gradually turn grey in outdoor environment. Some may find this attractive, but oiling restores the original rich tone.
Sweeping off dirt regularly can help prevent staining and make annual maintenance easier.
Address spills immediately using mild detergent and water to avoid permanent marks.
Ensure proper drainage, as standing water can damage the bamboo.
Avoid strong acids, alkalis, or harsh high-pressure cleaning, which may erode the surface.
