362840 2005-06-11 01:18:00 Having just been to the Brass Monkey Rally, the short-comings of my tent's water resistance became apparent. Luckily it was only mist and frost.

So I have an older 3 pole nylon igloo. 20 yrs old. Strong and better supported than current models. Most tramping tents are two pole only.

I could buy an equivalent Fairydown or MSR but the $700+ price tag rather chokes for something which is used annually at present.

Any thoughts on water-proofing? I could buy lots of silicon spray but it would be expensive and only lasts a year. Dip it in light machine oil? Nylon might not like that and it would be messy to use. Fat? Wax? :help:

362841 2005-06-11 01:49:00 I find a nice motel room has excellent waterproofing.

Went to a bike rally a couple of weeks ago, Grabbed a motel overlooking lake Taupo with a private spa pool in the unit, Mix that in with a dozen Export golds and some Hells Pizza and its all good....

362842 2005-06-11 01:58:00 What about scotchgard (www.3m.com). I know it is expensive, but it works:) 4bes (2848)
362843 2005-06-11 02:04:00 Yep, Scotchguard works for me, but you will have to redo every year. Oil or silicon may be better inside the tent if there's not much room :)

After recently spending a night in a tin caravan with no sleeping bag up in the 'high country' -10 degrees I can recommend Metla's motel room/spa... but preferably not with him in it while you're trying to sleep/soak :D

362844 2005-06-11 03:09:00 Those other compounds mentioned may be ok, but the best proofing for nylon, used over many years of tramping is Glendermids' "Wettex", it is also cheaper and goes a long way. Aerosol sprays are fairly expensive and not very good.

The method of application is to dilute it 1 part Wettex to 4 parts mineral turps.

Put up your tent ot flysheet stretched tightly, and brush the solution well into the nylon and allow to dry.
A second stronger solution can be brushed onto seams and stitchings.

Edit: Incidently one Wettex treatment will last several years.

362845 2005-06-11 03:29:00 How to Waterproof a Tent here ( . webguru . com/waterproof-tent-solution . htm" target="_blank">www . webguru . com)

Saturate a tent in a solution of sulphate of zinc, sal-soda, and tartaric acid and it will withstand both light moisture and heavy rain .
Dissolve 4 oz . sulphate of zinc in 10 gal . water; add 1/2 lb . sal-soda; stir well until dissolved, and add 1/2 oz . tartaric acid . Put the tent cover in this solution and let lie 24 hrs . Take out (do not wring it) and hang up to dry . --Grinnell's Hand Book on Painting .

---------------------

++ Linseed oil is an old remedy .

++ Check sporting goods stores . Scotch Guard and similar spray-ons have limited life, are expensive, and are only rain repellant .

++ Go to the Warehouse and get a large blue plastic/fibreglass tarp . Keep in the boot of the car at all times; also a smaller one ($4) is good; use when on picnics, for car repairs, etc . IF it rains, throw the large tarp over your tent, and have spare cord/rope and stakes to tie it down . You may want to use another one for the ground as well .

362846 2005-06-11 03:35:00 LOL Steve, I would prefer the Wettex :)

Linseed oil is ok for cotton/linen, that is the basis for an oily Black Japara, but is no good for nylon, and takes for ever and a day to even begin to dry. If you roll up the tent with the linseed oil still oily, it will stick together.

362847 2005-06-11 03:51:00 Terry - I was going to add "that is only good for cotton or canvas", but wanted to see how long a PF1er would shoot at the Linseed idea. SIX MINUTES - good going !! :D Strommer (42)
362848 2005-06-11 04:17:00 Right Steve, can't pull the wool over the eyes of an old hand :thumbs:

For those that remember or even have the old black Barbour 'Thornproof' motorcycle toggs, they sell a linseed oil based cream dressing called strangely enough 'Barbour Thornproof Dressing' . This is ideal for turning dry proofed cotton parkas into oily parkas .

Mind you, you'd be hard pushed to find a genuine black parka these days, it's all fancy coloured fashion wear jackets that dont even cover your bum in sports shops nowadays :(

Barbour aquired the W . Backhouse parka manufacturing firm in Wanganui a few years ago, and their material quality improved by bounds .

I wouldn't be seen in anything else but a Barbour .

Like Met, count me out of tents and give me the motel . Quite a boyscout is old 001 .
