Waterproofing boat cover

[mike rousseau]

Hello all

 

My cover isn't exactly keeping all the water out... Is there a good product/spray to seal her back up again or should I shop for a new one?

 

 

Thanks

 

Mike

you can buy liquid silicone at CTC in the camping section (or you used to be able to - haven't looked for it in a few years) . If you spray it on once or twice a year it should do the trick. I used it lots when I did a lot of camping and tents started to weep; cured it every time.

Mike,

 

3 cans of Scotch Guard on my clean dry canvas mooring cover has done it for me once a season for my 19 footer. I do 2 foot square sections at a time and mark it off with blackboard chalk as it doesn't show a wet edge. Cover is 19 years old. Paint on sealer has been suggested to me but the Scotch Guard has worked and if it ain't broke I don't mess with something. If and when she won't bead any longer I will get a travel cover for her and save on the shrinkwrap.

The best waterproofer is 303 Fabric Protectant, but its pricy. The next best is Starbrite Waterproofing PTFE (I buy it in the gallon jugs). You should wash the cover before you waterproof it. You can machine wash it, but you should rinse it twice since hte detergent will prevent the waterproofing from working as well. Once its dry I use a deck sprayer to spray my canvas then let it dry well.

I think I read yesterday that this may not be the best for boat covers and it can change the colour of the cover. Someone said it changes the colour to white. Haven't tried it myself but just so you know.

I was thinking about using that stuff... The never wet...

 

I don't care at all what the cover looks like to be honest so I don't mind a color change...

But I don't wanna spend $50 a year waterproofing a cover I can replace for $250-300

I think I'll get a new one when I replace the floor in my boat...
