Got a leaky tent? Or worried that it might leak? Seams are the area of a tent most vulnerable to water incursion, so it makes sense to reinforce them a little. This is especially true if it's an older tent (or perhaps a more budget tent).

Buyer’s Guide: Choosing the Best Tent Seam Sealer
Camping, as a recreational activity, has really exploded over the years. Tents and the relevant tent seam sealants are a dime a dozen, but sealants all differ in three main areas:
- Cure time.
- Type of tent fabric.
Usability is a decisive factor when selecting a sealer for seam sealing. A sealant is one of those products that you’re most likely to use under bad weather conditions. This is why it’s advisable to have an easy-to-use sealant when you go camping.
One of the factors that affect a sealant's usability is the viscosity of the product. The thicker the product, the more difficult it is to apply to tent seams.
Water-based products are very easy to apply and they often come in padded nozzles or spray cans. If you have the option, I suggest a spray can over a padded nozzle—sprays are very quick and easy to use.
A spray can, by design, allows you to apply the sealant more efficiently and evenly to the tent seams. The trade-off, however, is that you need to spray a spot twice. This eventually leads to some wastage in the long run.
Another factor you have to consider is how much time you are willing, or are able, to put aside for the tears to seal. Most sealants should take 4-12 hours to fully cure, but you can hasten this process by carrying a curing accelerant.
Waiting for a sealant to fully cure isn’t an option if it’s raining. Remember that when buying a tent seam sealant.
Type of Fabric
Before deciding what product to purchase, consider what material you plan to use it on. Manufacturers design tent sealers with specific materials in mind.
Polyurethane coated tent fabric is common in tents, making them the most widely available material in the market. This is a low-cost way for companies to make your tent waterproof.
Polyurethane, however, is not the most durable material around and is often prone to damage. Sealing these tents with a urethane-based product should prolong their lifespans.
Silicon coated tents don’t tear or need seam sealing as often as Polyurethane coated tents. Silicon is usually used in higher-priced tents, such as tarps and ultralight tents. However, any tears or rips wouldn’t be solved so easily—you’d have to sew the tears before using a silicon-based sealant.
The best seam sealer will vary with each unique set of needs. That said, the Gear Aid SilNet Silicone Seam Sealer is the best choice if you are looking for a well-rounded tent seam sealant to suit all your camping needs. This product has been tried and tested and remains the go-to option for experienced campers around the world.
Another noteworthy mention would be the Peregrine McNett Seam Grip—the most versatile sealant in the market. That’s a close runner up. If you can afford it, buy the two together.
By carrying the most durable and the most versatile tent seam sealers with you, you’re essentially preparing for every possible scenario mother nature can throw your way.
