Attached are pics of my deck one year after a total sand (floor sander) and application of Sikkens Cetol SRD semi-transparent. The SRD is a 1-coat application. Because it's wet on the deck, pics don't accurately reflect the amount of graying all throughout (i.e. the deck appears much grayer/ugly when dry).
Because it's cedar, I've been hesitant to apply an opaque stain, but actually thinking of it now, as stripping and cleaning (and/or sanding) and staining is getting very old.
Deck is in 100% shade, guessing not much airflow underneath, underneath is not stained (and too low to ground to do so now).
What I'm after is significantly longer time between re-application, even if it is at the expense of asthetics, if that's what it comes down to. I'm hesitant to apply another semi-transparent. Love what the wood looks like with clear, but that is a joke - don't even get a year out of them.
thanks,
Mark
