As above i needed to reproof a 2 rib bivvy,that even though stated at 10,000 fabric has only been used for 8 day sesions and was leaking all over , no waterproofing,at all now,acts like drips through cotton t shirt, so ive used 3 coats of non gold fabsil, but havent tested yet and have no idea ,howvlong it lasts?, hope it works

What bivvy is it warchild??
You sure it's not condensation?
I've never re-proofed any shelter and never suffered leaking.

how old is it?
how old is it?
hi to below posts its a vision kenuick quick rib- jim shelleys one?, the 2 rib bivvy rated at 10,000 hh, its 2-3 years old but only had very small bank time, stored dry , i think being stored for 2 years has sent it funny,
its no aqua or trakker, but hey there all made in the same china factorys, so should have been ok, only thing that might have made its coating go to poo, is i was under a big tree in the rain and after just 10 mins after set up, it was dripping all over the underside, onto my bloomin chair and all my stuff ,while getting rods sorted, i presume its made worse by the bigger drips of the tree hitting it if you will

You're 100% sure it's not condensation yes?
You can buy a new Vision 2 rib shelter for 70 quid so don't go mental on the Fabsil - you'll spend more on that than the bivvy is worth mate.

agreed,might of been better to just get another 2 rib of jrc or someone,anyway, also the fabsil even though it seems to be the holly grail of go to waterproofing, i did my chair and unhooking mat at the same time 3 coats,after posting this - i thought ill just pour a little water over my mat,
straight through into it, could see the wet colour change, it defo did no waterproofing on my matt, nothing on my unhooking matt, hope my bivvy is ok

You waterproofed your chair and unhooking mat?

You do realise you cant waterproof every fabric? Only those with a tight weave / mesh?
Mats and chairs are not designed to resist water so the weave is quite loose, wont matter how much fabsil you pour onto them. It would be like trying to waterproof a tennis racket or Colander.
Plus, higher wearing surfaces like a chair, the fabsil wouldnt last too long.
I waterproofed an Armo MK3 and it helped, it wasnt that only but i never used a second skin.
If its leaking when raining thats one thing, if you wake up and the roof is moist thats condensation.

I've used Fabsil and find it brilliant. I've only ever used one coat as that does the job. I would expect it to last at least a year between reproofing. When I did my brolly last, it wasn't because it was leaking but was getting 'heavy' during a storm as the water was clinging to it, probably not helped by a bit of 'spod spill' on it either. Afterwards it really was like a ducks back and a quick flick was enough to put it away dry.

Would you do a brand new bivvy to act as a barrier. Like ceramic coating or waxing a new car.
Thinking of doing the tempest see if it actually reduces condensation

Dont waste your time bud.
Condensation is formed by temperature differences. Unless you dont plan on breathing all night you are going to get it.
Sleep with your door open, and vents open. It does help.

It's more likely to make the condensation worse as the material wont be able to breathe as it were , thats always been my experience of Fabsiling bivvys anyway.
Best way to help with condensation is use twin skins and leave the door open abit to help even out the outside/inside temps

I just cannot believe the amount of people that totally unnecessarily !! Fabsil bivvies ?
I have a few bivvies some are over 10 years old and have never needed reproofing ! most of the time its condensation dripping unless you have damaged it in some way
like for instance its delaminated and thats normally quite evident it looks like a used durex hanging from the roof
the other common thing is simply DIRT a simple wash with a brush and plain warm water will most times restore the beading properties

I've never treated a bivvy either, got a 10 year old M3 that is still watertight, water doesn't bead on it like it did when new but it doesn't leak
In reply to Post #14
Likewise, I treat my waterproofs but never a shelter.
I can imagine treating a shelter may extend its life but I treat my brollies like crap anyway..... I'll patch them up where I rip them but if I can get four or five years out of each one I'm more than happy. Never had one lose its waterproof qualities other than rips but Fabsil aint gonna help there.

Overall leaking on a bivvy is more likley to be crap seams. The Chinese will do anything to cut costs and make an extra penny.
Just run some seam sealer on your seams on the inside of your bivvy. Should help the leaking no end.
Had my Mk1 Tempest brolly from the day they came out and never reproofed it. Has a skull cap and and open front.
I dont look after my kit either but a bit of seam sealer on cracked or loose seams works for me.

That's not always the case mate. I audit manufacturers in China. For sure, some are a joke, but others are up there with the best in the world.

I can only speak from personal experience.
And what you order and what you get from them is usually two different things.

As I understand it its the PU membrane on the fabric that is the "waterproof" bit, some more expensive fabrics use a breathable membrane that is also waterproof. The outer fabric/nylon simply adds robustness to the structure/garment. The fabric is impregnated with something that repel's the water - it doesnt make it waterproof per-sey - so in fabsil its the silicon in it that repels the water away (i.e. bead off) without it the outer fabric becomes water logged and eventually will make it through the water proof membrane. So the point of the repellency is to keep the water away from the delicate waterproof membrane
Fabsil (and most "water proofers" of the same ilk) simply disolve silicon in a solvent, you then apply the solvent containing the disolved silicon on the material and the material absorbs it. The solvent then evaporates leaving behind the silcon on the fibers of the fabric. This silicon will come away over time, and hence needs replacing to rejuvenate the repellency (beading) on the fabric.
Some bivvys clearly use better materials than others - the membrane on my M3 is a lot thicker than my tempest brolly - and hence would stand up to a lot more water on it before it leaked.
....so in a long-winded way - fabsil makes the water bead away from the fabric and the inner membrane, but alone doenst make the material waterproof - if your shelter leaks like a sieve then it sound like the membrane is pretty ****ed. Time for a new bivvy as fabsil is unlikely stop every bit of water making it through.
But I agree with the others - be sure its penetrating and not just condensation before throwing away your hard-earnt.

If you are convinced that your shelter fabric is letting in water and have decided that to re-proof the exterior fabric is the only viable option then don't paint it on with a brush or sponge.
Buy a large pump atomiser (garden centre, pet shop or el cheapo shop) and spray it as a fine mist on a dry day. This will prevent the sealer being pushed into the membrane and sealing the microscopic breathing holes in it.
But as has been said I've got nylon Bivvies going back 25 years and two Aqua Union Jack badged bivvies that have never been touched which are still waterproof

100%
Last time I re-proofed anything was my old Nash canvas oval bivvy - canvas does need re-prooing now and again.
If it's leaking and you can't see a hole - clean it and dry it properly. Bet it's cured.

Great bit of kit Keebs but combination of Nash canvas over a 50" wavelock was murder to carry home on the bus along with all the other kit carried for a couple of nights session if you wern't able to dry it out before leaving.Couple of times I had to stay longer than intended for just that reason and a couple of times fellow carpers took pity on me and gave me a lift home

i use to use brick sealer but its not as good now a days, could leave my chair in the rain,great for river stalking when waterproof, and i did my matt to stop them getting soaked and heavy , and smelly, and i had a flat with no shed etc

I had the canvas over a 50". Not that I'm the type of person to put the door down but I reckon if you did you could put a light show and strobe in there and no light would escape.
I put some canvas waterproofer on it and it turned a strange yellow colour

I had one. It's where i learnt the phrase . " Don't touch the tent" . canvas shrinks the gaps between the fibres when it gets wet so becomes heavier and doesn't leak. unless you poke it, and make a gap for the water to come through.. Canvas is bloody heavy, especially when wet but it's warm in the winter.

Still got mine - I'm going to see if I can get it to peg down over my MHR brolly and resurrect it this winter.
(Nash Oval Profile long gone!).
I don't think they made many ovals in canvas.
There was something very cosy about hearing the rains dull thud
