Waterproffing for Sunbrella material?
 

Does anyone know what product I should use to waterproof Sunbrella material, the stuff bimini tops are made from? I have a boat cover for my small boat made with that stuff and it needs to be waterproofed.

Thanks

Slip,

How about just using Scotchgard. Don't know how long it will last but will probably work for a season.

Thanks but I think scotchgaurd may be better for inside fabrics, I could be wrong though.

I did some research and the sunbrella site actually reccomends this product http://www.303products.com/store/cat...TOKEN=61254556

I also read that you should NOT use a silicone product over the sunbrella

I think I will get some of this 303 stuff and try it out unless someone else has another firsthand experience.

Many moons ago I waterproffed a whole bunch of leaky cancas tents with Thompsons Water Seal. Don't know what Sunbrella is, but it may be an option.........

Slip. I've used this Satrbrite product with good results on Sunbrella material.

I used the Starbrite on my sunbrella t-top. lasted well over one season.

I used to work for the Haartz Corporation in Acton MA which made several marine fabric constructions. I was focused on developing automotive interior trim products, but had some exposure to all products. Sunbrella is a solution dyed acrylic fabric. Unfortunately since it is only a fabric it will never be truly 100% waterproof. Haartz makes a coated product called Seamark with combines the fabric with .007” of vinyl making it 100% waterproof. I shot an e-mail over to the product development manager for this area of the business and he recommended a product called Raggtop Fabric Protectant. You can find it at www.wolfsteins.com. He reiterrated the fact that you should not use silicone.

I use 303.
It should be applied in bright, direct sunlight. It's not cheap but it works very well.
