The tent cloths of our roof tents are impregnated and coated as standard. In addition, the seams are taped. This makes our tents maintenance-free.
For the L-series tents 140L, 180L and 220XL, there is one exception: the seam of the zip where the lower tent for the 140L, 180L and 220XL is zipped on.
This seam should be impregnated before the first use and 1-2 times a year thereafter. This can be done with a seam sealer, waterproofing spray or beeswax.
To improve the beading effect of the water, it is not a bad idea to treat the outside of the tent with an impregnator after 2-3 years. The fabric does not get wet so intensely and the tent dries more quickly.
