I purchased this to make a Philmont compliant tarp that would weigh substantially less than the crew gear one provided. Tarp was 10x12 with grosgrain loops to as tie outs. I laminated an additional reinforcement layer at each tie out (PU side to PU side) using Seam Grip +WP that I thinned with toluene and applied with a brush. No delamination after 12 days at Philmont with rain for a few hours to all day on 10 of those days. This material is essentially rainproof and will actually hold standing water. Things remained dry after 12+ hours of driving rain at over 8000 ft of elevation. I have not weighed the tarp alone, but with stakes and line it was just under 2 lbs.
Fabric was super easy to work with compared to membrane silnylon and is much stronger at resisting thread pulling through the fabric when under tension.
Thank you Dave for the fantastic write up and review of the 1.1 oz Silpoly PU4000 for your tarp! We would love to see photos from your Philmont trip, be sure to tag us on social media!
Used for a bathtub floor for a tent. The PU coating reduces the slip of normal silpoly making it a lot easier to sew.
Perfect application! We're glad you found this fabric for your bathtub floor, enjoy!
I have made a few free standing tents over the last 2 years and I found out silnylon is a slip and slide when used as a tent floor. This Silpoly PU4000 has enough urethane to create some traction and still stay pretty light. I just wish RSBTR would update their projects page so the DIY community can continue to share and inspire
Thank for your review David! That is a great idea for a project. We are working on a new space for makers to share projects, stay tuned! We'd love to see photos of your project, here is a link if you'd like to share! https://forms.gle/erH82vVyNZF8UPao8
I recently purchased some silpoly 1.1 Oz pu 4000 to make a pack cover. The material it is a little heavier than regular soap Ali 1.1 Oz but it works great as a pack cover.
Thanks for your review Phil! This is a great fabric for making your own pack cover. We'd love to see photos of your project, be sure to tag us on social media!
Great materials and excellent service, with super prompt delivery to Australia.
Thanks so much JWP! We're glad you were able to receive your materials quickly across the pond! We'd love to see what you're creating, be sure to tag us on social media!
