is this for waterproofing or uv protecting

Both. Does an effective job if you apply as directed. Have been using it for 7+ years...

I used UVX1. I was waterproofing a canvas drop cloth that we had painted. we used it as a gazebo cover. Worked great.I put it in a garden pump sprayer, which worked great by the way.

It's not waterproof, but it still stays on pretty well. It does prevent tanning.

I never tested it so I am assuming the UVB passed through since it is a thin plastic and I would have hoped the manufacture did test that. Also I felt it was safer to have a protective barrier between the water and the light tube just in case. UVB does pass though plastics and some glass but may be "diluted" or refracted and depending on the thickness and the clarity of the material it can be blocked completely. Also UVB does dissipate with distance so you need to read the details to ensure it is placed appropriately. Hope this helps....

Yes it is. We did spray a UVB and waterproofing protectant on it as well. Our firstnone faded reall bad in the hot sun. So. Hope this one will not do that

I don't believe so, I purchased the product to keep the rain water from seeping through our 10x10 canopy at craft shows. I believe it is more of a repellant for water than a sealing agent.

It's not a waterproofer. It is a moisture inhibitor and helps eliminate water stains

Per the manufacturer - Soft yet durable backing layer pampers paint finish and protects vehicle from sun, dirt, dust, moisture and pollution. This cover is NOT waterproof.

I can't say from experience, but the whole product is designed to be waterproof. I see that it is waterproof vinyl or plastic covered on top with a nice soft material.

It provides a little shade and I would assume the covering blocks UV rays but I'm not 100% on that.

It does prevent oxidation. I have no idea about UV protection though. I used it on an application that is exposed to water every day, but is indoors.

While it appears to be completely sealed and weather resistant, I believe I read in the accompanying literature that it is not officially rated for exterior applications. I would trust using it in under a soffit if it did not rain directly on the light.

It is not waterproof, it is like a heavy mesh or screen and intended to provide shade only. Look at fabrics for awnings, those are more like a canvas and are usually waterproof.

I am not sure, but for outdoor applications with lots of sun exposure and weather, I like to use a marine varnish. It will last a long, long time.

Yes. It won't be water proof, but if you are just sealing it, this stuff will work. If you need water proof, look for a water proof varnish.

The UV-protection is for the prolonged life of the plastic, it's not nearly enough to stop plants from growing. My setup is in an area where it gets a lot more shade than I'd care to get and everything still grows great.

I'd be afraid to try that on anything of value. 303 works great when freshly applied and dry, but wears away over time. On our Sunbrella enclosure of our boat, we re-coat it two or three times during the 5-month sailing season. Between coats, I find it still necessary to hit it lightly with an electric power-washer (1800 psi) to remove dirt and bird droppings. I'd hate to think what might happen to art work with all that abuse. 303 is probably the best canvas water-proofing around.
