3. Maintenance
The Suncast Horizontal Stow-Away Storage Shed is designed for low maintenance and long-lasting durability.
3.1 Cleaning
To clean the shed, simply hose it down with water. For tougher dirt, use a mild soap solution and a soft cloth or brush. Rinse thoroughly with water. Avoid abrasive cleaners or harsh chemicals that could damage the resin material.
3.2 Material Durability
Constructed of steel-reinforced, multi-wall resin, the shed is engineered for strength and durability. Its all-weather construction provides water resistance and UV protection, preventing cracking, peeling, or discoloration over time.
4. Troubleshooting
- Difficulty during assembly: Ensure all parts are correctly oriented and aligned according to the instructions. A rubber mallet can be used to gently coax reluctant parts into place. Having an extra set of hands can also be beneficial, especially when attaching the lid.
- Lid not staying open or closing too quickly: Verify that the gas shocks are correctly installed and functioning. The soft-close hinge is designed to prevent rapid closing.
- Shed instability: Ensure the shed is placed on a flat, level surface. Consider anchoring the shed to the ground using appropriate screws and anchors for increased stability, especially in high-wind areas.
- Water leakage: While the shed is water-resistant, ensure all panels are properly seated and sealed during assembly. Check for any gaps or misalignments that could allow water entry.
