Buying Guide: Key Purchase Considerations
- Size accuracy and finished dimensions: Some tarps list precise finished sizes (e.g., 12×20) while others show approximate measurements. Confirm the exact finished size before purchase to ensure a proper fit for your space or project.
- Thickness and durability: Mil thickness directly affects tear resistance and weight. Heavier tarps (12–20 mil) provide lasting protection in windy conditions, while lighter options (5–8 mil) offer portability and easier handling for temporary use.
- Material and UV resistance: Most consumer tarps use virgin or recycled polyethylene. UV resistance helps prevent sun damage and extends lifespan for outdoor use under sun exposure.
- Grommets and edge reinforcement: Grommet spacing (common around 23 inches or 3 feet) and reinforced edges reduce tearing and improve tie-down security, especially in windy or stormy conditions.
- Edge finishing and sealing: Heat-sealed edges reduce fraying and water wicking at seams. Look for tarps with reinforced corners or inner rope reinforcements for added durability.
- Intended use and weight: For vehicle covers, pool area shade, or ground protection, select a tarp whose thickness and weight match the expected environmental stress. Heavier tarps are less prone to gust damage but may be more cumbersome to handle.
- Budget and coverage needs: Balance cost against durability. Reversible or multi-use tarps provide versatility, especially when you need both interior protection and weatherproof outdoor use.
- Maintenance: Clean tarps with mild soap and water; avoid harsh solvents that could degrade polyethylene. Proper dry storage can extend their life.
