If you have to cover a large area undiluted nik wax. If its a small area latex glue painted on outside

As Skev has said Nik Wax is an excellent product. If it's a really big area of Canvas I find Storm Brush on Canvas Waterproofer is a wee bit cheaper (I paid about £13 for 2.5 litres)

This is probably a stupid question, but how often should a tent be re-waterproofed?

Depends on useage but every five years or so should be OK.

When it leaks. We have one about 25 years old, never re-proofed, and it don't leak.

MIne must be on its 5th or 6th season, no need to waterproof yet. I think it'll depend on the thickness and quality of the canvas, so get yourself a good heavy tent. One of the other tents we have is probably 9 or 10 years old and I've never heard of it being waterproofed.

Is it the whole tent, or just seams? If just seams, simply rub them with a plain old candle. Works fine to help seal the thread/needle holes.

I have tested out a concrete water repellent on about 2 foot sq of canvas - totally undiluted ! smeared the b**ger on in great dollops - left it a few days in the shed, bingo - works a treat - at £4 for 5 litres from wicks can't be bad -- will now try it out on a large section of my sail tent and see how that goes !

what about the risk from flames? As we all know too well, when a tent without fire proofing goes up, it is a disaster within seconds.. look at Tewks or Tintagel, tents ignited and reduced to smouldering embers quicker than most can react. Best remedy i found for this over the years is to buy a good quality tent at the offset and expect it to have a finite lifespan.

What, canvas tents? As far as I was aware, the tents burnt in the plastic camp at Tewkes a couple of years ago were plastic, not canvas.
I've tried setting fire to canvas to test how likely my furnace is to set the fire shelter on fire. Answer - not really.

that is reassuring !! -- those flimsy nylon jobbies in plasti are not good at all the ones I have seen have the 'Do not expose to fame ' warning on them.

Tintagel 3 years ago, canvas tent went up in seconds, i was there. Sterkshoff Belgium, Canvas tent reduced to ashes in what seemed like less than a minute, 2 inhabitants were lucky to escape without serious injury, saw that one with my own eyes too. Cant say about the one at Tewks, it may have been plastic as you say Guthrie but i have seen canvas tents go very quickly.
Sterkshoff one was particularly hairy as the tents were packed in very close together, the resultant panick and confusion was something i am not in a hurry to see again. The only way they prevented a tradgedy was by forcefully collapsing the tent and smothering. Very quick thinking by someone who had not been drinking as much as the rest!!

So do we have any methods of making canvas type tents fire resistant?

I've done some testing of my own and found that nylon bursts into flame immediately but I had to hold a naked flame onto normal tent canvas for 10 seconds before it reached a flash point and burst into flame.

There was a fire in the plastic camp at Tewks. Have only seen one canvas fire with a brazier too close to an awning at Berkley. It was me who spotted it and raised the alarm. Seemed to be large flames leaping skywards but when we got the awning away from the source of heat and Bucket who was tall enough, doused with water there was actually remarkably little damage and it went out easily. If I recall correctly, water proofing like nikwax is also fire retardant but shoot me down in flames if you know better... It ay have had separate fireproofing but whatever - it was effective.

Langley, I don't think its fireproof, but it is not pertochmical based so definatly doesn't increase the flamibility of the Canvas. This is exactly the reason why I use it. Its more expensive than alot of other solutions but definately on the safer end.

Well if nikwax is based on ethylene vinyl acetate with stabilisers, as the internet suggests, that is an organic compound like a kind of plastic with extra bits, so flammable. Just not as immediately flammable as tar would be.

If you want a safe and cheap fireproofing try BORIC ACID. Mix boric acid with water and just spray it on, let it dry and Robert's your mothers brother!

FLAME RETARDANT : Boron is an effective chemical flame retardant for an ample array of products. It is also used for wood, plywood, textile products, cotton, paper and cellulose.

How to Fireproof With Borax

By Francis Walsh, eHow Contributor



We use many naturally occurring fire inhibiters every day. Some of them are used to put out the flames while others inhibit the spread of fire. One of the lesser known fire inhibitors available to the consumer is borax. Borax is a natural mineral mixture that is soluble in water and can reduce the spread of fire on properly treated surfaces.

Difficulty: Moderate

Instructions:

Things You'll Need

Borax

Boric acid

Sprayer

Wooden spoon

Measuring cup

Gloves

Pot

1. Put 4 cups of boric acid in a pot on the stove until it reaches 212 degrees (when the liquid begins to boil). Stir the boric acid as it reaches its boiling point and then lower the stove to a medium temperature range. Let the boric acid reduce its temperature for two minutes.

2. Pour 1 cup of dry borax into the boric acid and begin to mix them. Continue to add dry borax into the pan with heated boric acid until the boric acid is unable to absorb any more borax. You know you've saturated the boric acid completely when flakes of borax reach the bottom of the pan yet will not dissolve in the liquid.

3. Turn the stove off. While the liquid is still warm, fill a hand-pump, pressurized sprayer with the solution. Close and tighten the sprayer's lid and pump the handle to pressurize the air inside the sprayer.

4.Spray the fireproofing liquid on natural construction material like wood or fiber and other flammable materials. Four cups of solution should cover at least 1,000 square feet of surfaces.

5.Let the fireproofing solution dry completely before handling anything treated. The solution must be allowed to dry to get the benefit of the fire retardant properties. Apply more solution on surfaces that are in close proximity to potential fire sources.

Borax can be obtained from your local chemists or DIY store. Don't get hot, get Borax!
