I'm looking for feedback with regard to re-waterproofing the seams of a boat cover constructed of sunbrella. While sewing the top I used the smallest needle I've been able to find for the ultrafeed: #14(90). Is there any smaller needle available? The person I sewed the cover for says the seams are leaking.

Would a spray on flurocarbon based retreatment like '303 High tech fabric guard' help to seal the seams?

Anyone reading this who sews boat tops semi-professionally? - would you see 're-waterproofing' as a service over and above the initial product cost? or do you know of anyone who treat the seams on project completion?

thanks,

Hi Cordm:

There are a couple of things that you can do regarding seam leakage. 

The first, and most effective thing is to baste any seam with #129 Seamstick tape prior to sewing and then sew right through the tape.  The adhesive from the tape imbeds itself in the holes and stops ant leaks before they start.  I do this routinely using a 20 gauge needle and V-92 thread, and I have yet to have a problem with leaking seams.

The second is to coat the inside of a seam prone to leakage with 29301 Plastiseam.  Do this on the inside only as it may leave a whitish streak.

303 fabric card is a good product, but it is best not to apply it until the Sunbrella is at least 3 years old.  Treatment prior to this may result in a mottled appearance because of the sizing that has not yet worn away from newer Sunbrella.

I hope that this helps.
