EWT5 5 US Gallon, Long Lasting, Silvery Patina | Semi-Transparent (1 Pack), 640 Fl Oz (Pack of 1), 18927 Millilitre

I used the product on western red cedar siding. So far I am satisfied. I thought it would be interesting to show the effect on the cedar. The first two pictures show the difference of treated and untreated cedar. The lower part had been treated a few weeks before these photos have been taken while the upper part are untreated shingles that had been newly installed. The 2nd and 3rd pictures show the color change 24 hours after application (top) compared to 6 weeks after treatment (bottom). I decided to use this product in order to darken the red cedar as well as to control the aging process. Unfortunately cedar tends to age very unevenly depending on water and sun exposure. My decision to use eco wood treatment was made in the premise that this product allows me to enforce a more even aging process and to darken the shingles in a short time. The alternative would have been paint or stain with all its associated issues regarding peeling, maintenance etc. I was close to going with a dark stain and to do this properly I would have dipped and brushed each shingle individually ore install in order to get the best technical result (testing only on the visible side will lead more rapidly to peeling and decay as humidity can travel from the untreated side through the wood). Dipping and painting about 7k shingles would have been a lot of work, complexity and cost. Eco wood treatment is super easy and done with a ladder and sprayer in no time. I did invest in a battery powered sprayer (Makita) which proved invaluable over the manual pump and spray I used for the first trial. In summary: so far so good!

My designer found this product on-line in preparation for a home remodel where I wanted to get a rustic/aged look while also providing protection from weather on interior and exterior 6x14 Doug Fir beams and cedar tongue and groove ceilings and facia. This product doesn't have multiple color options. Here is an update on two projects: 1) 300+ Ft of new cedar fencing (applied one year ago). This was the test for the home wood needs. Sprayed with 5 gal backpack sprayer. One coat and NO tint. I was looking for the silver patina look. The first photo shows new fence on left and 10yr old fence on right that was already pretty aged. The new cedar has a more brownish look than I desired, however, I really like how it turned out. I did apply to existing fence too (right side of photo) and there wasn't a noticeable color change to my eye... 2) House- Photo 2 & 3 are exterior Doug Fir, Cedar facia and Cedar T&G. Photo 4 is interior same wood type. Applied one week ago (7-2022) OK, this is going to be a lot of details. The two wood types are different grain etc and it gave me the variation I was looking for. 1) I test sprayed interior Doug Fir beam that was going to be dry-walled as a test (I was concerned about how this would react with Doug Fir). We felt the color was too green. Designer brought me some CCE Maroon tint (i think it's Sherman Williams tint they use to custom color paint). This tint is very concentrated and the goal was to eliminate the green on DF. 2) I kept cuttings of DF and Cedar T&G to sample with. Started with 1 quart sample with 1 tablespoon of tint. Very red. Took a 1/8 tspn measuring spoon and put 8 drops into one quart. Not 8 1/8 tspoons. I let the tint drip from the end. Too red. Went to 4 and landed on 2 drops/qrt. Tested on DF beams that would be drywalled and cutting samples. 3) Cutting samples left in the sun for days/weeks. Ended up with final product 2 drops/qrt. 4) Bought Ryobi One electric 1 gallon sprayer because the ceiling was high and I didn't was to pump. Mixed 5 gallon Eco with 8 drops per gallon tint in 5 gal bucket. Used this to fill the sprayer. Used 9 gallons and it took about 3 hours of spraying on a ladder. Very happy with final color after just one week. I expect it to continue to change over time. I am concerned about a few of the beams that are exposed about 10" so I am putting 2" copper cap on them. As to the protective nature of this product, only time will tell but I will be keeping an eye on it.

I've always wondered how exactly this stuff works. But so far it has worked well. It does give the wood the sort of silvery grey look that aging would impart. My wooden planters have held up well so far - though I haven't put it to severe test with termites and such.

We were pleasantly surprised. It was easy to apply with a sprayer. Nice silver barnwood look. Six months later it looks great.

Product did as advertised. Pretty amazing, really. Our cedar deck turned a nice shade of light brown. Went on easy; cleaned up easy. We’ll have to wait and see if it actually preserves the wood and turns silver like it promises.
