What to use to make a top for gazebo?

What if you use the cloth top, but treat it with marine uv protectant like they do on sail boats and yachts?

This may sound crazy and I have never had one so it's just a thought, do painter grade tarps come in that size. I ask because they just seem to last forever and although not exposed to the elements I was actually thinking about the cost factor. If you have to replace it every few years may be more cost effective. Also you can use fabric paint on them because on this site people have done so I just don't know if they sell a sealant to protect paint fading and maybe make it water resistant. Now you may want to really check first and see if the canopy that you can be is coated with anything to keep harmful sunray off of you and/or if you can buy that and spray it on which ever item you purchase. Just a wild thought 😞.

You can use the Shade cloth available in the garden department at Lowe's... it is available by the foot...you would need to sew at least 2 sections together to make the width.

We have also used rippled tin to cover a Harbor Freight garage... but for the gazebo... the rippled fiberglas would be better... comes in several colors

Sunbrella fabric is UV resistant for outdoor use, you can find it on Fabric.com and then you would have to sew it yourself or find someone to do it for you.

What if you bought the fabric top and then rolled and painted it in the "rubber" stuff that is waterproof. It is expensive but it might be cost effective for your situation. I am pretty sure it is available in white.

You can purchase a product called Sunbella cloth on line it is the same fabric used in awning, it is easy to work with and I have sewn it with even a very light weight machine. I have purchased ends at Sportman's guide on line very inexpensively. No much choice on color but what I got was pretty neutral.

Rippled Fiberglas? I think it is the answer I was looking for!!!!

thank you so much.
