Seam Sealing Service - Tent

Seam Sealing Service charge for Tents and Two person tarps:

Lunar Solo, Skyscape Trekker, Lunar Duo Explorer, Haven Tarp

Many of the shelters made by Six Moon Designs require an after-production sealant to be applied to all the sewn seams that would be vulnerable to precipitation. This not only creates a watertight bond between the pieces of fabric and fills the tiny holes created by the sewing machine, but also adds strength to the seams. This process is required to make the shelters completely waterproof.

Shelters can be sealed by the customer or our in-house seam sealing service can be added at check out. See below for further details.

  • We understand space, time and comfort can be limiting factors which is why we offer an in-house seam sealing service.

    A few things to note:

    • The seam sealing service can increase processing time. Orders requiring the seam sealing service could be delayed by up to two weeks depending on seam sealed shelter order volume. Please inquire for current lead times.
    • The sealant is applied mostly to the outside of the shelter and though dries clear, may be slightly visible.
    • The seam sealing service is not available for polyurethane coated shelters (Skyscape Scout, Lunar Duo Outfitter)
    • Shelters made with Dyneema do not require the seam sealing service.


    Any shelter sealed in-house is guaranteed to be effectively sealed and waterproof. If you are dissatisfied with the appearance of the seam sealing service, we can offer to refund the cost of the service and exchange the shelter for an unsealed one.  

  • Six Moon Designs always encourages customers to seam seal their own shelters in order to more intimately understand the setup and seams of their shelter. We offer for sale two pre-made seam sealing products. The appropriate product for each shelter is listed below.

    Lunar Duo Explorer, Haven Tarp, Gatewood Cape, Lunar Solo, Deschutes Plus, Deschutes, Skyscape Trekker

    Lunar Duo Outfitter, Skyscape Scout


    It is also possible to make your own seam sealer by mixing the following recommended ingredients 1:1 by weight:

    • GE 100% Silicone Caulk
    • Mineral Spirits

    Mix vigorously until a smooth and the consistency of a thick cooking oil.
    Apply using a small squeeze bottle or small brush (3/4” foam brush works well)

    Lunar Solo Seam Seal

    Seam seal looks great. Cleaner than I’ve done before. I haven’t had the tent in weather yet…but it will see plenty on the PCT…
