I am busy repairing my old boom cover & the fabric is rubbery covered type stuff & has faired remarkably well considering it's thirty odd years of age but in the most exposed surfaces it has suffered from ultra violet deterioration.It is still pretty good but I wondered if there is some sort of rejuvenating unction I can apply?
I have read of some sort of re water proofing stuff somewhere previously & wondered if it really works.Anybody have some experience of this problem?
 
Well I have just bought a new product-Storm Canvas reproofer-its a thin white liquid water based which when on and dried seems to work very well and you can get 5 litres of the stuff on Amazon(Tents Spares) for under £30 delivered.Do not buy direct if you live in Scotland as they want £12 postage!

Thanks for that.I only really need about half a pint of it but it's worth knowing.I shall check out the camping scene! :)

With PVC covered material, unlikely a re-proofer will be satisfactory when the PVC starts to break down. You could try vinyl paint as used on inflatables. http://www.rib-shop.com/product.asp?cookiecheck=yes&P_ID=372

In order to use that site I had to enable cookies which looked like a hell of a polava so I did'nt bother.It's a good tip though so I will check out vinyl paint as used on inflatables,maybe cheap non boaty alternative will be available?

Just click on Shop and you will go straight in, go to Inland Marine restoration products.
 
Fabsil or pop into B&Q/Homebase etc they sometimes stock their own. Could also try Renovo who supply dye's and waterproofing for car hoods, boat sprayhoods etc. http://www.renovointernational.com/testimonials.php

As an aside I looked into re-dyeing my sprayhood but it has to be the right fabric, got to be cleaned, died then sealed - all adds up for what could not work in the first place - Googling indicates this also but i bet it works for some, it's all down to the right fabric apparently!!

It's want Land Rovers owners do to avoid silly prices, they use it on their canves tilts - same stuff half the time ;)

"Fabsil?" I shall check it out.It has also occurred to me that I need some sort of miracle treatment for my sprayhood or possibly to buy some new material to try & repair/manufacture a new one.It's amazing what you have to become an expert in when you buy an old boat to try & do up! :D
 
I'm in the same boat er... that is to say my spray hood is also faded and defintely has no waterproof properties. I was going to make a new one up this winter but kitchen installation took priority :rolleyes: Good luck with it, you may need to borrow a professional machine for the stitching...

I've resown by hand about twenty feet of stitching in my boom cover & have always repaired my sails by hand in the past so I think I can get away without a sowing machine.Could'nt find any rubbery paint in Homebase or Wicks so the search continues.
The sprayhood will be a project for next winter.Very satisfying in practice!
Good luck to all & thanks for the info.

I've just backed a carpet square with an adhesive similar to Copydex. It leaves a clear rubbery layer. I needed to spread talc over it to remove the surface tack. May be worth a try? Is Copydex just the same as the big tubs of PVA you can get in builders merchants?

That sounds worth checking out.I've got a load of "WATERPROOF EVO-BOND PVA" stuff I've used in the past but I think it dries hard.I shall carry out some tests :)

Used it, works, http://www.grangers.co.uk/product.cfm?cat=17&productid=20
But: whole canopy took 10 bottles of spray (aerosol) and still could use much more, the stuff was not cheap (just this was only stuff in local store). A lot of solvents with not so much silicone in, probably formulated for leather and such. I'd advise to buy a liquid for brush-on application, and meant for canvas - knowing similar here in Poland that has much more silicone in. Btw: canvas should be well washed first, no grease (fats, oils) in it before silicon. And really dry...
Or other waterproofing, like the mentioned http://www.canvastentshop.co.uk/products/canvas-care/storm-canvas-tent-waterproofer-(5-litre).aspx

I'm not so much worried about waterproofing the stuff as it dos'nt really matter if a boom cover (or sprayhood for that matter) is a 100% waterproof.
What I am more concerned about is the integrity & strength of the fabric.Obviously when the PVC covering/impregnating rubbery stuff wears of it is a lot less durable.
