Seam Seal

Please seal the seams by yourself to make shelters and tarps better in the waterproof function.

We try the best to make the seam holes as small as possible in our technique of sewing by double stitching with using the special thinest needle and carefully selected thick spun yarns. However, In case if it was heavy rain over the night, there would be a possibility to pass moisture or water-drop through the holes.

  1. Set up the shelters or tarps when it is sunny and in the normal windy condition.
  2. Seal all seams which have possibility to pass moisture through with using the small brush attached with the sealer or fingers in such a way as to cover the seam lines very thinly.
  3. Dry up perfectly (it will take several hours or an overnight depending on its weather condition). We recommend to use talcum power over the seam seal after drying to prevent from sticking together inside the sack.

Condensation is a phenomenon that a vapor inside the shelter condensed in the shelter surface. it happens caused by the gap between outside and inside in the temperature, when the temperature inside the shelter increased caused by human sweat or body heat or the diffusion of vapor from the ground, the vapor is cooled in the surface of the shelter then becomes water drops.

It is necessary to ventilate air the inside the shelter when condensation is happened, which means to get rid of the temperature differences between inside and outside.

It might be indistinguishable whether condensation or water dropping in the rain.
