 Does every tent need seam sealing? Not all tents need seam sealing but it's recommended to seam seal any tent that is not already factory sealed or that has been used extensively. If you notice water seeping through the seams of your tent it's a sign that you need to seam seal it. If you're unsure whether your tent needs seam sealing or not check the manufacturer's recommendations or contact them directly for any advice. It's important to take care of your gear so it can take care of you. Thanks for watching and enjoy your next dry camping adventure!
