How to Maintain Composite Decking
Composite decking is known for its durability, low maintenance, and resistance to weathering—making it a popular choice for outdoor spaces in humid climates like Singapore. While it requires less upkeep than natural wood, regular care helps preserve its appearance and extend its lifespan.
1. Regular Cleaning
Dirt, dust, and debris can accumulate on the surface over time.
Sweep the deck weekly to remove leaves and dirt.
Wash the surface every few months using mild soap and water.
Use a soft-bristle brush to scrub gently along the grain to remove grime.
Rinse thoroughly with clean water to prevent soap residue.
2. Prevent Mold and Mildew
Although composite decking resists mold better than timber, moisture can still cause buildup in shaded or damp areas.
Keep the deck dry by ensuring proper drainage.
Trim nearby plants to improve airflow and sunlight exposure.
Use a diluted vinegar solution or a composite-safe cleaner to remove mold spots.
3. Avoid Stains and Spills
Composite decking can stain if spills are left unattended.
Wipe up food, oil, or drink spills immediately.
For stubborn stains, use a gentle household degreaser or a cleaner recommended by the decking manufacturer.
Avoid harsh chemicals or bleach, which can damage the surface.
4. Protect from Scratches
While composite boards are tough, they can still scratch under heavy use.
Place protective pads under furniture legs.
Avoid dragging heavy objects across the deck.
Use outdoor rugs made from breathable materials to prevent discoloration.
5. Manage Heat and Sun Exposure
Composite decking can get warm under direct sunlight.
Choose lighter-colored boards if your deck receives full sun.
Add shade structures like pergolas or umbrellas to reduce heat buildup.
Rotate furniture occasionally to prevent uneven fading.
6. Seasonal Maintenance
Clean thoroughly before and after the rainy season.
Check gaps between boards to ensure proper drainage and airflow.
With consistent care and simple maintenance, composite decking can stay beautiful and functional for many years. Regular cleaning, protection from stains, and attention to drainage will keep your outdoor space looking fresh and inviting.
