Bleaching Oil?

42769 Views 16 Replies 8 Participants Last post by  painttofish
I had this estimate today. The house is sided with cedar shakes. Customer applied bleaching oil 10-12 years ago. He wants it redone. I thought that this only to be applied to new wood... am I wrong? Also Is spray application ok? how should the surface be preped? Thanks.(we don't have many houses with cedar in my area)

Yes, you are wrong

Ummmm....not really
You will find many painters that do it, but I'm telling you, the customers are pissed because it doesn't last, and call me because I do it with a big fat brush
Spraying does not force the oils into all the nooks and crannies it needs to be in
I strongly recommend NOT spraying
Besides, that stuff is nasty

I'd clean any mold/mildew with Jomax or sim if needed, powerwash depending on how bad it is and how comfortable you are with the machine (keeping in mind you can destroy that siding pretty darn quick with that machine)

In most neighbor hoods around here, 90% of the houses must have cedar shingles on three sides, and white trim
If not, the neighborhood gets bulldozed to put up a Dunkin Donuts and a CVS Parmacy
See less See more
Hard to say w/o seeing it
Not sure if it's normal blotchy or too blotchy
If the (possibly sitting on the shelf since last fall) oil was well shaken, and well mixed while applying, and the surface was cleaned and brightened, then I'll have to go with normal blotchy
That stuff does look like that sometimes
Generally it weathers ("bleaches") out more even

I wouldn't put a semi-trans over it at this point
That will defeat the bleaching oil, and it could look pretty goofy in 6 months

Pics would help
...man just reading about it and I can smell it...that stuff is nasty
I think that's a wise move
