Daniel,
Between you and Diamond Jim, the both of you gave me the creeps. Stopped by to look at the only 2 ESI stain jobs we did this year.
The first one was a 3 or 4 month old PT deck, stained with ESI's Timber Oil. Prepped with Restore (sodium percarbonate) wood cleaner, brightened with citric acid, and rinsed well. Normal prep.
Two separate apps of Timber Oil into the wood. It was at 12% moisture from a Delmhorst meter when stained. Had a call back and put down a 3rd Timber Oil application on the lower deck. No big deal, its new wood. And this part of the deck is nearly sitting on the ground, with a bare soil base.
Russell sent me the stain gratis, without a clue. Came home after the estimate and there it was on my doorstep. Gave the stain to the customer, one other reason I stopped by today was to give them the remainder of the stain. Cleaning out inventory for winter storage.
This job was completed on July 7th of this year. Today, the floor is very faded and blotchy, but again, new PT wood close to the ground. This deck gets a ton of sunlight for most of the day.
Horizontals are fine. But in one corner that is shaded, see the first picture. Look familiar? Something is wrong.
It is not paraffinic oil. Paraffinic oil is a byproduct of petroleum, nothing close to a vegetable or flax seed that makes up linseed oil. We have been using another paraffinic oil stain for six years without this problem. But then again, we rarely work on new wood.
Something is wrong. Either new PT wood, kiln dried or not, is infected with a mold or mildew. Or there is something in the Timber Oil promoting mildew/mold growth. Or, there is a new species of mildew/mold infesting the East coast.
The 2nd ESI job is a red mahogany, stripped, neutralized, rinsed, and stained with WoodTux in mid June of this year. Does not look all that great after 6 months, but without a bleach mix on hand cannot tell if the dark areas are mildew/mold or just dirt/weathering.
