Welcome To My World
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?
Yes, you are wrong
Also Is spray application ok?
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
how should the surface be preped?
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)
(we don't have many houses with cedar in my area)
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
