Check Latest Price on AmazonWhich One Should You Choose?
If budget is tight → the 12' x 20' 10 Mil (ASIN B015RVUPVU) gives the best durability per dollar. If you need broad coverage for multiple pieces → the 16' x 20' 2 Pack (ASIN B07FW851FK) covers more area and includes reinforced hems for secure tie-downs. If you want the best size-to-price balance → the 18' x 24' (ASIN B07D9S74ZL) is a strong mid-range choice. For maximum single-piece coverage choose the 25' x 40' (ASIN B07D9SWC8L) but plan anchors and handling accordingly.
Best for Specific Scenarios
- Protecting a dining set: Trademark Supplies 16' x 20' 2 Pack (B07FW851FK) because the two large sheets can overlap for full coverage and secure tie points keep wind out.
- Covering a grill and cushions: 12' x 20' 10 Mil (B015RVUPVU) because its thicker material resists punctures and grease stains better than thinner tarps.
- Whole patio/seasonal storage: 25' x 40' (B07D9SWC8L) because it covers multiple items at once — plan for helpers to lay and anchor it to avoid damage.
Frequently Asked Questions
How do I prevent water from pooling on a tarp-covered table?
Create slope: prop the tarp up in the center with a rigid support (PVC pipe, broom handle, or temporary frame) so water sheds off the sides. Pull the tarp taut and anchor corners every 3–4 feet. Regularly check after heavy rain and clear any small pools quickly.
What’s the best way to stop a tarp from blowing away in gusty spring winds?
Use reinforced tie points: thread ropes or ratchet straps through rust-proof grommets and secure to anchors, patio railings, or heavy furniture. Add screw-in ground anchors or weighted sandbags at corners and avoid loose flapping by keeping the cover taut.
Will covering cushions cause mildew?
Covered wet cushions can develop mildew if moisture is trapped. Either store cushions indoors or remove covers soon after storms to dry. If outdoor storage is necessary, use breathable covers briefly and open them to air on dry days.
