Sealing the tent construction and the formulation of the tent door

If your tent is used in a long-term rain or often damp environment, the corner line (the junction between the bottom and the sides) of the tent must be sealed. The surroundings of the tent floor mats should be erected with the poles, and never be coated with sealant liquid in a cold and humid environment. Apply only cloth and tarpaulin (shiny) in the tent. Sealant fluid should not stick to the side of the tent that is not covered by the membrane, because there is already waterproof glue there. Please apply several layers of thin book in several times, the effect will be better than just one thick layer. Coat the sealant liquid around the tent floor mat, and wipe the glue back and forth evenly. Please carefully follow the drying instructions on the sealant liquid tank to avoid improper use to damage your tent.

The curtain of the tent is heated and sealed with tape in the factory. In most weather conditions, there is no need to further seal the tent. But if you are using the tent under continuous rain or long-term humid environment, we still recommend that you add sealant to some places inside the curtain. Put the lining of the tent curtain outside the erected tent, with the degree of film (shining) facing up. Add the sealant liquid to all the seams of the tent according to the method described in the previous paragraph, and carefully follow the instructions on the sealant liquid tank to let the glue dry completely.
