Why Joint Sealing Issues
Tent textile itself is usually treated with a water resistant or water-resistant layer, however the joints are a different story. Every stitch penetrates the material, developing a potential entrance factor for water. Manufacturers normally use seam tape at the manufacturing facility, yet this tape has a shelf life. Warm, UV direct exposure, repeated folding, and general wear create it to lift at the edges. When that takes place, water will locate its method during any type of actual downpour. Sealing your joints, whether for the very first time or as regular maintenance, is among the most inexpensive and most efficient methods to maintain your shelter really water-proof.
Types of Seam Sealers
Joint sealers typically fall under a few groups, and picking the best one relies on your tent's material.

They tend to be a bit messier to apply and commonly require to be thinned with a solvent, but they produce a versatile, durable seal.
Polyurethane-based sealers are the more common choice and job well on polyester or nylon tents with a polyurethane (PU) covering, which explains the huge bulk of budget and mid-range tents on the market. These sealers go on like a thick liquid and remedy into a versatile, rubbery strip that flexes with the material rather than splitting.
Joint tape is a 3rd choice, regularly made use of at the manufacturing facility yet additionally readily available for home repairs. It's an iron-on or adhesive-backed tape that covers the joint directly. It can be excellent for quick fixes but is generally less durable over time than a properly applied liquid sealer.

How to Apply Joint Sealer Properly

Clean the joints with scrubing alcohol to get rid of dust, oils, and old sealant deposit, then let them completely dry totally.
Use a thin, also layer of sealer straight over the stitching, expanding somewhat beyond the joint on both sides. Avoid globbing it on, given that thick applications can split much more conveniently and take much longer to heal. Many sealants need at the very least a number of hours, and canvas totes often a complete 24 hours, to treat effectively, so plan this job well before your following trip instead of the evening before.
