Seam Sealing
Before taking your Six Moon Designs tent into the backcountry,
you'll want to seal all exposed outside seams with a
silicone based sealer. This can be done either by applying
the SilNet™ seam sealer or
making your own seam sealer.
Once properly sealed you should have years of maintenance free seams.
Unlike polyurethane seam sealer, silicone seam sealer won't peal off your
seams over time.
- If you've purchased the SilNet™
sealer, follow the package instructions for proper application and curing.
However, here's a helpful hint regarding application. To better control
the flow of sealer, and make the SilNet™go farther,
purchase a plastic glue syringe for about $1 at any art supply store,
and cut off part of the tip to make a larger opening. You should be
able to seal the entire tent with 1 tube. Note: Contrary
to the SilNet instructions, seal the outside of the seams.
-
If you're into saving a few bucks, you can easily make your own seam
sealer. This is especially cost effective if you're sealing several
items (tents, stuff sacks, tarps, etc.). To make your own sealer,
follow the instructions below:
Steps for Making Your Own Silicone Seam Sealer
- Purchase the following items. They should be are available from most local hardware stores.
- GE Silicone II clear tub and sink caulk - The small tube will
make enough to seal several tents. The large tube will make
enough to seal everything you own and then some.
- Mineral Spirits - Commonly used for cleaning paint brushes.
- Small brush to apply the sealer - A 3/4" foam brush works well.
- Electric Drill with Paint Stirrer attachment.
- Dilute Silicone In a glass jar, mix one part mineral
spirits with one part silicone caulk (1 oz mineral spirits and 1 oz
silicone should be enough.) Using the drill with paint stirrer attachment,
mix well. (Note: You can mix by hand with a regular paint stirrer, but
caulk is stiff, so will take much longer to mix.) When mixture is the
right consistency, it will be smooth and milky, and flow smoothly when
applied. If it's too thick or lumpy, the waterproofing won't flow well
into the seams, or be absorbed by the exposed threads.
Sealing Your Tent
-
Seal the Tent - Working in a well ventilated area,
pour a small amount into a paper cup, and close the jar to keep rest
of sealer from thickening. Use a small brush to apply a thin
coat of sealer to all exposed outside seams.
Spread seams open flat and hold them taut while applying, to ensure
even coverage. If sealer thickens while applying, stir in a few drops
of mineral spirits. Use waxed paper to separate overlapping areas
of wet sealer.
-
Strip the Floor - Adding a series of strips with the sealer
to the floor of the tent will reduce the tendency of your sleeping
pad from sliding around on the silicone nylon floor.
-
Drying your Tent - Hang your tent, or lay it out
flat, and cure for at least 8 to 12 hours after sealing. Hanging with
simple wire hooks on the overhead support brackets of a garage door
works well, as does hanging over a shower rod with floor sides together.
Once cured, the sealer dries to a clear matte finish that is nearly
invisible, and will be both durable and flexible.
