The canvas in a king tent gives it a unique atmosphere full of character and charm. It is also more durable and longer lasting than most alternatives. The downside is canvas takes a little more looking after.
All king tents are waterproof, they may however suffer from a small amount of initial leakage along the seams. When material is stitched together you are essentially punching a series of holes through the material. As with any good quality tent we use Egyptian cotton which is designed to expand when wet thus filling the holes, until the cotton has fully expanded there may be a very small amount of leaking.
The canvas is waterproof, you can tell by the 'beading' of water droplets on the outside of the tent. When the water stops that beading (and the tent takes longer to dry out) it's time to re-proof your canvas. If you use a cleaning agent (see below) you will also have to reproof the canvas afterwards.
Don't put a tent away wet. This is a golden rule for any tent or marquee. You don't need to put the tent back up again, just leave it draped out in a garage or undercover and move around a few times to ensure it is completely dry before packing it away.
Always remove any leaves or foliage off the tent when you take it down.
Tents can get muddy, especially when used at festivals. The most common place is around the bottom of the walls or the underside of the groundsheet. When dismantling your tent try to fold it so any wet or dirty parts of the tents are facing similar dirty/wet parts. Don't make your job harder by making other parts of the tent dirty!
Let the mud dry and then brush off with a stiff brush/broom
You can use a canvas cleaning agent but if you do ensure you reproof the canvas afterwards.
