decking stain

[medindexer]

I want to use a water-borne decking paint, and would like to use a product that lasts as long as possible (who enjoys redoing this sort of stuff?). I don't mind paying considerably more for something if it lasts considerably more time. I know there are some products out there (Scandinavian perhaps) and Jotun make something called Demidekk decking and garden stain - I've come to prefer their Butinox products for wood.

Can anyone recommend anything that the consider is definitely longer lasting than the more usual Ronseal, Cupinol etc. products?
