The only thing you can tell them is you cannot guarantee the longevity as it is not how the product was intended to be used. Correct that a marine spar varnish would extend it, but still...no guarantee. A lot of our weavers just refuse work if it is to be left outside. I had a customer with 4 reed porch rockers and she was going to paint them (so reed, not binder cane)...I told her to do them quickly, she changed her mind and decided to seal them natural color...but waited and they got mold spots. Hard to see but...I gave her complete instructions. Sue
@Administrator I totally understand. I did 8 chairs in pre-twisted seagrass rush for a customer who insisted on keeping them on her porch all year long - in Central Texas heat and weather! It was the second time they were being replaced, but she would not put them inside when she was out of state for most of the year (this was her vacation home.) I applied a couple of coats of linseed oil hoping that they would not turn black like the last set. 🤷🏼♀️
Hi! Is this reed or cane? In any case, it can not be left out in the weather. If you are using it under a porch or screened in area, I would suggest shellac. Sue
@Administrator It is #5 round reed and 6mm binder cane. They plan to have them outside. 😕
My customer is going to put the finish on. I was thinking of suggesting that he use spar varnish - the type that is used on boats.
