All Tarptent must be seam-sealed with silicone.
We offer seam-sealing kits ($6-$8) containing premix silicone, a foam brush, and a latex glove in the webstore.
We also offer a seam-sealing service ($35) in our webstore. The service includes sealing the fly seams and the application of non-skid lines on the interior floor. Please note that seam-sealing is weather dependent and ordering this service may add over a week to the wait time.
