THINGS TO CONSIDER BEFORE BUYING SEAM SEALER

Seam sealer seems like a must-have thing for a perfect camping trip. However, there are many factors you need to consider before buying one to make sure you will get the most suitable and the best tent seam sealer for your tent and also other gears. 

1. The fabric types of your tent coating

There are different types of fabric to make a tent coating and hence, you need to know exactly about yours. Bear in mind that not all sealers do work well on all types of fabric, and knowing which works effectively on your tent’s material will help you choose the best tent seam sealer. 

Polyurethane-coated fabric is a common material in the tent market and hence, it is an ideal choice for the tent companies to make a waterproof tent and keep the price competitive. This material is not really a durable one and is often prone to damage. To prolong the lifespan of your polyurethane-coated tent, use a urethane seam sealer.

Silicon coated tents don’t need to be sealed as often as polyurethane coated tents. Silicon is widely used for high-priced and ultralight tents and gears that mostly work well on waterproofing you and the contents. However, to make sure that your camping trip will not be bothered by any raindrops; you should prevent your tent from any leak using a silicon-based sealant. Only silicon adhere to silicon, bear it in mind.

Sometimes, the tent coating is made from both polyurethane and silicon (on two different sides), which is called silpoly or SilPolyPU coating. If so, you will need to find out which side is coated with silicone and which side coated with polyurethane before sealing the seams. 

If you are using a tent that made from cubenfiber or Dyneema, you will not need to seam the seals in most cases. However, prevention is always better than cure. Get yourself a spray sealer and set the seal quickly over the seams. 

2. The thickness of the seam sealer

The thickness of the seam sealer differs among the variety of its kinds and contributes a lot to the effectiveness of the product. The thick seam sealer is hard to apply, but it bonds the specific parts of the tent well. On the contrary, you can apply the thin seam sealer easily but it also runs easily. Be careful when applying the product and thin out the sealer when necessary by mixing them with a small number of mineral spirits. Make sure that you take out enough product and seal the seams altogether.  

3. The applicator of the seam sealer

The seam sealers come with different options of applicator:

  • Tub/bottle with nozzle: you can apply the sealer to the fabric directly using the nozzle that comes with the tub/bottle
  • A can with spray nozzle: you can spray the product directly on the area you want to seal
  • Tub/bottle with/without paintbrush: use your own paintbrush to paint the product on the seams or the brush that comes with the sealers made by the manufactures
  • Tub/bottle with built-in applicators: Some seam sealers come in a tub/bottle that has a built-in applicator, the most convenient way to apply the product

4. Quantity of the seam sealer

The sealers come in different sizes and based on your need you can choose the size which suits you the most. For example, you just need to buy a small tube if you seal a small/personal tent. If you plan on a family camping trip, you might need a larger quantity. Consider buying a big tub/bottle if you need to seal the seams regularly, which also saves you a lot of money.

5. The cure time of the seam sealer 

An important factor to consider when choosing a seam sealer is how much time you are willing to spend on/put aside for the seams to be sealed. The waiting time varies from 02 – 14 hours, and can be hastened by a curing accelerant. 

6. Price of the seam sealer

Most of the seam sealers are cheap to buy but there are still differences in price among them. When considering the price of the product, think about below points:

  • Brand, quantity & type of the seam sealer
  • Where you buy the seam sealer, online or in-store. You might find a good deal online and are able to compare the price of many seam sealers; however, some people prefer to have hands-on experience.

FAQs

1. What is a Tent Seam Sealer?

A tent seam sealer is, as its name suggests, a product that helps you seal the seams of a tent. Its sealants seal the gaps between the seams to prevent it from allowing the raindrop to come in the tent inside. Hence, it reduces the risk of getting wet during the camping trip if there is a night rain. Although the tent you buy has been sealed or even double-sealed, some parts are simply stitched. These areas will not be as durable as these sealed ones, so you should take care of them with the seam sealers. 

You can also use the seam sealers as a maintenance for the seams, which might wear off after a long time of usage. Check it regularly, especially before setting off for a trip as you don’t want to wake up in the night realizing that there is a leak right above your sleeping bag.  

Another usage of the seam sealer is to repair the small tear/crack in the seams of your tent, which might be caused by a falling branch or rock. The sealer then will attach the part together and the wound will be bound. 

2. Should you Seam Seal a New Tent?

If you have a brand new tent, check the seams if they have been sealed or not. Apply the sealer at the area that has yet to be sealed, and remember to check the seals carefully before setting off.  

3. How to use seam grips?

Follow the below steps to apply the seam grips easily:

  • Clean the seams 
  • Wear the gloves, take out a thin film of seam grip and apply inside the seam. If you do not wear the gloves, wash your hands with soap after application
  • Let it dry (approx.8-12 hours)

An investment in a new tent can cost a fortune and it is not necessary if you know how to maintain it. Seam sealer is a cheap and convenient way to do so, and with it, you will never worry about getting leak during the camping trip.
