Repair of a leak:

1. Locate the leak: Pour water or soapy water over the fully inflated mat. If possible, dunk the entire mat into water. Apply additional pressure by folding mat once or twice.

2. Bubbles or a hissing sound indicate a leak. Note leak location and mark if possible.

3. Deflate mat, but not completely leaving some air in the mat to prevent glueing top and bottom surfaces together when repairing. Clean and dry the area around the leak.

4. Quick Repair: a fast temporary repair to get you through the night.

    a. Cover entire puncture with a thick layer of Exped Textile Glue.

    b. Allow Exped Textile Glue to saturate the fabric and dry until tack free (approx. 5-10 min.).

    c. Trim one of the self-adhesive patches to be about 1 cm or 1/4 inch larger than the pool of glue covering the hole. Make sure to trim patch in a curved form.

    d. After trimming patch, remove the backing paper, and cover the glued puncture with the self-adhesive patch.

    e. Now you are ready to go back to sleep.

    Note: The fabric patch is temporary and intendet to prevent the fresh Exped Textile Glue from adhering to a sleeping bag or tent floor. Fabric patch can be removed in the morning and longer term repair can be completed using the steps below for Small Repair or Large Repair.

5. Long-Term Small Repair:  punctures and small cuts less than 1 cm or 1/4 inch

    a. Cover entire puncture liberally with Exped Textile Glue.

    b. Allow Exped Textile Glue to saturate the fabric and dry until tack free (approx. 5-10 min.).

    c. Apply a second layer of Exped Textile Glue to completely coat first layer.

    d. Allow Exped Textile Glue to dry until tack free (approx. 5-10 min.).

    e. Apply a third layer of Exped Textile Glue to completely cover second layer.

    f. Once Exped Textile Glue has dried (approx. 5-10 min.), mat can be inflated and used.

    g. The maximum bonding strength is achieved after 8 hours.

6. Long Term Large Repair: tears and cuts greater than 1 cm or 1/4 inch

    a. Seal cut or tear with three coats of Exped Textile glue as in Small Repair instructions above.

    b.Trim self-adhesive fabric patch beyond sealed cut by at least 1cm or 1/4 inch.  Make sure to trim patch in a curved form. Note: with any cuts, monitor this drying step making sure the fabric edges remain flat. Tamp curling edges flat as the glue dries and becomes tacky.

    c. Apply a layer of Exped Textile Glue over area to be covered by the patch.

    d. Peel paper backer off of self-adhesive patch and cover sealed cut while glue is still wet.

    e. Apply a trail of glue around the perimeter of the patch ensuring that the Exped Textile Glue covers both the edge of the fabric patch and mat surface.

f.  Allow Exped Textile Glue to dry until tack free (approx.5-10 min.).

g. The maximum bonding strength is achieved after 8 hours.

Tips and tricks:

-     Fabric patches are ideal for adding tear strength and abrasion resistance to repairs. Do not expect an airtight seal using fabric patches alone. A long term airtight seal is only achieved by proper application of the Exped Textile Glue as noted in the Small Repair instructions.

-     Placing a flat pan with warm water over the patch will aid in speeding the cure time of the glue.

-     In the event of a long rip, it is best to first sew the edges of the rip together before glueing and patching. Patching might even not be necessary.

-     Don’t confuse an apparent loss of air when moving your mat from hot to cold environments. In such situations, air volume contracts but no air is lost. Just re-inflate the mat to desired comfort level.

-    Dirt can contaminate any valve and cause slow leaking of air. Rinse valve in a pan of water to get rid of dirt.

-    Storage: store all mats unstuffed with both valves open in a dry, dark space, e.g. under your bed. Store the sealed adhesive glue container in a cold environment such as a refrigerator. After usage of the adhesive glue, make sure to advance the remaing contents to the neck of the tube.

-    Since the abrasive force of dirt is a fabric’s primary enemy, use mild soap and water to occasionally wash mat. Never put in washing machine or dryer.

-    Beware of exposure to heat: Do not expose an inflated mat to direct

    sunlight or heat sources. This may cause the air to expand and create pressures that can cause seams to fail.

-    Keep mat away from sharp objects like thorns, corals, jagged stones or similar.

-    Do not use mechanical airpumps which could lead to everpressurising rupturing the seams.

-    Use Exped Textile Glue also for other fabric repairs. For larger holes you might create a backing with removable tape which you remove after curing.

-    Use sealant also as seam sealer.

-    Another good Textile Glue is called Seamgrip by McNett which you might find in your outdoor store.
