Things to Consider When Choosing a Tent Seam Sealer

Before you buy tent seam sealer there are a few things that you need to consider. We've covered all the bases with the important questions to ask before settling on a product. It's important to get the right one for the type of tent that you have.

Does a factory taped seam mean I don't need sealer?

Just because of tent comes with factory taping at the seams, doesn't mean that it is fully waterproof. The taped seams do help in preventing moisture seepage, but it's not the same as seam sealing. You can seal right over the taped areas to add an extra layer of waterproofing protection.

Does the fabric type of a tent matter?

This is an important question to ask and the answer is yes. Some seam sealers work fine on any type of tent fabric. Some others are intended for nylon or other fabric types only. It is very important to read the manufacturer's information before you make your purchase. You should also look at the specifications of your tent to determine what kind of fabric it is made of. If the information is missing, then it's best to go with an all-purpose tent sealer.

How much sealer do I need?

This depends on the size of your tent. If your tent is large, you should buy two tubes of seam sealer to be safe. You should also have two brushes on hand to apply the sealer. Some tent sealants give you information on how much area a container covers. Always read the information on your label before purchase.

Answer: Most of them dry within 4 to 8 hours. The water-based quick dry types an be dry in as little as 2 hours. The rule of thumb is to read the product description for approximate drying times.

Answer: Most of them are used on the outside of the seams only.
