Extending Life of Bimini?

[Hudson Force]

I stand in agreement with Dennisjay regarding the use of less expensive water sealers. I've used the Thompson's Waterseal and the cheaper Ace Hardware sealers that are listed for application on wood, cement, and other surfaces. The Sunbrella representatives suggest that the use of these sealers will decrease the lifespan of their product by embedding dirt particles that will abrade the fabric. I still remain pleased with the less expensive brush on sealers and my Sunbrella continues to last well over ten years. My usual damage comes from chafe points that I try to avoid.

Thinwater's caution about the damage that these sealers can cause to the vinyl windows is important. I don't witness a runoff damage after the sealer drys, but any runs when brushing it on can permanently damage the clear windows and I'm very cautious with the edges.

Can you tell us exactly what you're using? Does it change the appearance? thanks, Pete

I too, am interested in Dennisjay's answer to your question, but I will toss in that my use of the inexpensive Thompson's or Ace Harrdware's water seal is easily brushed on and it does make the Sunbrella fabric somewhat darker even after drying. It's very effective in restoring the water repellant quality and it seems to last one year to eigthteen months.
