Hi again. Everyone was super helpful on my deck question in the Spring of 2019.....it still looks super..ty

In Nov 2019 we had a pressure treated pine fence installed..seems ok....Few issues..1) seems to a fair # of cracks, but I believe that is from the wood drying and 2) a fair # of the boards have this greenish/blue "stuff" on them. I got out my pressure washer and it does NOT come off.... I dont want to be 1 of those whinny customers, so trying to find out what this greenish/blue stuff is..... I have attached a few pics of the stuff....not the cracking!!

2nd part of my question.....Staining!! Thanks to the HOA I can 1) leave it alone and let it go that ugly grey look 2) paint it the colour of my deck..no ty....OR 3...a transparent stain! I want to go the transparent stain route....it is pressure treated pine.......Any recommendations on a good transparent stain?? I have heard Thompsons water seal is not a good product. I just want something to keep it from going grey.....which I believe may be a bit difficult with a transparent stain....but the HOA doesnt give 1 many options!! Thanks in advance

Probably part of the pressure treating process. The stuff that is surface can probably be sanded off if you want to go that route. Deeper in, you might have to try an oxalic acid was for decks.

I'd let it dry for a few weeks in good heat and CWF is better than Thompson.

Thnak you.....I got the sander out..100 grit and it wasnt coming off....I really dont care too much.....I wish the fence crew paid a bit more attention to their wood selection....I keep telling myself its just a fence,lol

The Flood Clear CWF-UV Exterior Wood Finish seems like a much better route. Thank you

I also believe it's part of the PT process. Sanding and scrubbing is the only way I've been able to get rid or lessen it. Depending on the pay I generally don't spend too much time on it. It doesn't seem to affect anything other than looks.


I really like the look of CWF although it doesn't hold up as long as I think it should. A semi-transparent or solid stain should hold up longer. IMO paint would be a last resort.

Poured rain last night....so the bottom portion of the fence is all dirty again, lol Will have to rinse it off again.

I will leave the greenish/blue stuff alone. I really need to stop looking at the fence as the more ticked off I get,lol I thought they did a decent job....then u see a fair # of boards where they put 8 nails in 1 spot.....nice grouping if your doing rifle practice,lol

Think will go with the CWF....seems to get v good reviews.....can 1 get away with just 1 coat on the fence? If I am lucky, the wife will paint it while I am at work,lol thanks again

I believe that green/blue is the PT chemical being brought to the surface with the sap as the wood dries. Pine - all of the softwoods - are full of sap. You could try sanding it but you go through a lot of paper due to gumming and no guarantee that it won't return.

CWF has a specific recoat window. 2 hrs if I'm not mistaken. If a 2nd coat is applied after that window it might not adhere as good as it should.

Yes, as its still wet it states......apply a 2nd coat if so desired....ty

Update (if anyone cares) and maybe some useful info

Bought the Flood CWF UV (clear) paint....finished product is not exactly clear, it does have a "glow" to it. We think it looks super.

Started to brush/roll it on..nightmare....1 section (front/back) was taking my wife and I nearly 1 hour to do....getting it applied to the inner edges was a pain!! Boards were 5ft high, approx 4" wide with about 1.5" spacing

I had enough of that, so looked at paint sprayers. Bought a Graco Magnum 257025 Project Painter Plus. Then I realized the sprayer not work with the Flood CWF UV paint, as its maximum was 0.015, while I found out that Flood wanted 0.017 as a min! I called up Flood and the gentleman, said no, this spray should work, but use a smaller tip such as a 313....he was surprised I was told 0.017.

Set up of the sprayer was a breeze (thanks to youtube) It reached the inner edges so much easier....and yes we back brushed!! Finished the whole fence in about 7 hrs and that included me cleaning the machine and putting stuff away! Fence looks great and so much easier with the sprayer.
TY for the help

.017 tip would be for siding and logs where you want a lot of material and back brush. for a fence 313 is a good size.

According to the email and FB response, 1 stated 0.017 and the other stated 0.019.....Guy on the phone was like "What!!" lol Glad I called.

Most of the CWF I've sprayed was with a 4/15 tip. When spraying wood it's beneficial to back brush/roll the coating. I often spray, back roll and spray again.


I've always loved the look of the clear CWF.

 

[flames9]

What i was concerned with was that the CWF was too thick for this sprayer as its max was 0.015 and according to Flood reps on email and FB I needed a machine that could handle 0.017.

 

[mark sr]

I don't know if I've ever used an airless that wouldn't support an .017 tip but I've been on the commercial end. Small airless pumps often need the paint thinned a little in order to spray properly but I wouldn't think you'd need to thin CWF to get it to spray.


A 4/15 tip is my go to size for most exterior spraying.

 

[woodco]

Dont pay any attention to recomended tip sizes. I would probably use a 313 for that fence myself.

And CWF is NOT thick material.
