waterproofing a tent

Post by bencollver3 » May 16th, 2020, 12:59 pm

I have a pup tent with no rain fly. I read about applying waterproof spray directly on the tent. Would it be better to leave the tent untreated and use a tarp as a rain fly? I imagine that might make the tent more breathable.

Thanks!

welcome

Trinity Alps are good a little further south

external tarp would be more waterproof and breathable. And heavier.

waterproof spray might work, I don't know which. Depends on the fabric too.

just a tarp would be more minimalist, lighter, cheaper

The spray-on type of waterproofing is not very effective in my experience. Adding a tarp as a rain fly would be better protection in anything resembling real rain. Unless your pup tent provides a bugproof interior (a real advantage!), you might consider leaving the tent home and just using a tarp with a ground sheet as your shelter.

I'm not sure it will be breathable if the tarp is laying flatly against the tent fabric. Double wall tents provide a few inches of space between the inner and outer walls.
