- Is this tarp actually waterproof?
- Yes. It is 20-mil vinyl, which is a solid waterproof sheet rather than a woven fabric. Water will not pass through it, though water can still get in at unsealed edges and grommet holes.
- How does 20-mil compare with a standard tarp?
- Most general-purpose tarps are 5 to 12 mil. At 20 mil this one is roughly twice as thick as a heavy consumer tarp, so it holds up better to abrasion, wind flap and repeated use.
- Can I use it as a roof or canopy cover?
- Yes, it is commonly used for small roof and porch covers. Tie it down through the grommets and slope it so water runs off rather than pooling.
- Is it flame retardant?
- The product is marketed for flame-retardant covering uses, but confirm the rating on the label before relying on it near heat sources or open flame.
- What size area does a 4x6 tarp cover?
- About 24 square feet. Measure your span first, and allow extra length for overhang and tie-down points.
