I just built a cedar deck, and I've got people trying to sell me
sealant. In fact I bought one: an expensive petrochemical that I will
probably need to reapply every year.
Here's my question: Do I really need to go down this road? I know my
deck is going to turn grey eventually, and that using sealants is just
going to slow the process down. Cedar already has mildew resistant
properties to begin with -- that's why we use the stuff for decks,
If I'm going to pressure wash my deck at least twice a year anyway, and
if I don't really care about maintaining the bright coloring, do I
really need to start spreading petrochemicals on it?
P.S. I live in rainy Portland OR
