Tent How to Seal and Proof For Winter Weather

There will come a time with any tent, where it may need to be reproofed, to increase or top up the waterproof layer on the tent, to prevent water leaking into the tent.
Purchase a waterproofing agent, and some seam sealant.
Wait for a clear, dry warm day.
Pitch the tent in an outdoor setting so there is plenty of ventilation.
Spray or paint the waterproofing agent to the outside of the tent.
Make you you understand what material your outer fabric is made of and then choose the right sealant and waterproof spray!
