If you want to order outdoor bamboo blinds, please let us know. We will produce your bamboo blind by using water-resistant glue. This does not involve any additional cost for you.
In case of outdoor application note that these materials are natural (untreated). It is like wood material taken outdoor without surface treatment. In a short time it will be mildewed.
We strongly recommend treating bamboo blinds for outdoor use with wood treatment oil from both sides(i.e. with Sadolin wood treatment oil). We do not recommend varnishing, because hardened weaving threads can not be rolled. Typically, with one box of wood treatment oil(0.75 litres), 16m2 ~= 172ft2 of material can be treated. Be careful with the amount of oil you apply. It must be applied in thin layer, which the bamboo blind material can absorb.
