A: No, it is not waterproof, however, it is water-resistant.
A: Yes, Sigman 5 ft. x 7 ft. Blue Tarp is waterproof. It is the same roof tarp used by many roofers to temporarily cover roof leaks before repairs. However, this tarp cannot be used a water container. Any water must be able to run off the tarp.
A: I think it is excellent depends on what you need it for. I have not tried it on any occasions to hold a large volume of water and let it sit there for extended time. I doubt many things can hold up to that. I have put it under the ditch that was dug right outside the foundation to prevent water from seeping into a old style stone-mortar basement, that works very well. Several people I know have been using it to cover the naked part of the roof when it rains in the middle of a roof replacement job that last for weeks or months (remember the roof has a pitch and does not retain and hold water). It worked well in those situations as far as I know.
A: This tarp is probably listed as "Finished Size 5 ft. x 7 ft., but it is slightly smaller that that. I didn't measure it with my tape measure but it's probably closer to 4',9" x 6',8". Just like a 2" x 4" isn't actually 2 inches x 4 inches at most places. I hope I answered your question.
A: 5 ft. x 7 ft.
A: Sigman 5 ft. x 7 ft. Blue Tarp is a finished size tarp. A finished size tarp's actual dimensions are usually within 1 - 3 inches of its nominal dimensions.
A: If you mean bicycle it may be not quite large enough to completely cover!
A: If my math skills still serve me right, yes! And with approximately 4" left over on the sides
A: It would "cover" it, but likely will NOT completely cover/surround it. I personally would use a larger tarp... an 8x10 should be good. It's better to have too much tarp than not enough.
A: I have no idea, as I use mine to cover my garden bed to prevent weed and grass growth. But if one converted the feet into inches, which comes out to be 148 inches, I would say it would cover a 26 inch tricycle very easily!
A: Some adult size tricycles are around 3 ft wide x 6 ft long. But you need to check the length and width of your tricycle. It is possible that the tarp might cover the tricycle, but would not be able to surround it.
A: The tarp that I received does NOT have grommets every three feet. There grommets at the corners and the long 7 foot side has a grommet in the center but there are NO grommets on the short 5 foot side.
A: Sigman 5 ft. x 7 ft. Blue Tarp's grommet spacing is every 3 ft approximately.
A: One in all corners and one in middle of (all) sides Very secured!
A: This tarp has a grommet every 3 ft.
